Stabilization of epoxyeicosatrienoic acids (EETs) levels via soluble epoxide hydrolase (sEH) deletion or its pharmacol. inhibition have been shown to have beneficial effects on inflammation, ischemia, hypertension and diabetes. Owing to the diverse role of EETs, current study was designed to evaluate the therapeutic potential of 1-trifluoromethoxyphenyl-3-(1-propionylpiperidine-4-yl) urea (TPPU), a novel sEHI against fructose-induced diabetes and related complications in rats. Sprague-Dawley rats (200 – 230 g) were divided into four different groups, each containing 10 animals. One group served as a normal control and received standard diet and drinking water. The second group served as a diseased control and received standard diet, 25% fructose in drinking water and was treated with vehicle only. The third and fourth groups received standard diet, 25% fructose in drinking water and TPPU (2 mg/kg) or metformin (150 mg/kg), resp. All treatments were given orally for 12 wk. At the end of the study, blood samples were collected to measure serum insulin levels and other biochem. parameters. Animals were dissected to collect tissue specimens for histol. and immunohistochem. anal. Animals fed on fructose and treated with vehicle demonstrated elevated blood insulin and glucose levels as well as high levels (P < 0.001) of triglycerides (TGs), cholesterol, low-d. lipoprotein (LDL) and homeostatic model assessment of insulin resistance (HOMA-IR) compared to naive rats. Similarly, the levels of alk. phosphatase (ALP), alanine aminotransferase (ALT), urea and uric acid were significantly (P < 0.001) increased in vehicle treated fructose fed animals. TPPU (2 mg/kg p.o.) and simultaneously fed on fructose for 12 wk substantially decreased HOMA-IR levels, lowered blood glucose, serum cholesterol, LDLs and TGs while high-d. lipoproteins (HDL) levels were increased compared to untreated animals. Metformin, a standard reference drug showed similar results. Microscopic studies of liver and pancreatic sections of TPPU treated animals showed marked improvement in cellular architecture compared to untreated animals. Current study demonstrated profound therapeutic potential of TPPU against fructose induced-diabetes and related metabolic complications which was evident by its attenuating effect fructose-induced hyperglycemia, hyperlipidemia and impaired renal and hepatic serum markers. This study involved multiple reactions and reactants, such as 1-(1-Propionylpiperidin-4-yl)-3-(4-(trifluoromethoxy)phenyl)urea (cas: 1222780-33-7Name: 1-(1-Propionylpiperidin-4-yl)-3-(4-(trifluoromethoxy)phenyl)urea).

1-(1-Propionylpiperidin-4-yl)-3-(4-(trifluoromethoxy)phenyl)urea (cas: 1222780-33-7) belongs to piperidine derivatives. The piperidine structural motif is present in numerous natural alkaloids. These include piperine, which gives black pepper its spicy taste. The piperidine and polyhydroxylated indolizidine derivatives have shown to be promising α-glucosidase inhibitors. The former are analogs of DNJ with an improved α-glucosidase inhibitory profile than that of DNJ. Boisson et al.Name: 1-(1-Propionylpiperidin-4-yl)-3-(4-(trifluoromethoxy)phenyl)urea

Alterations in histamine responses between juvenile and adult urinary bladder urothelium, lamina propria and detrusor tissues was written by Stromberga, Zane;Chess-Williams, Russ;Moro, Christian. And the article was included in Scientific Reports in 2020.Recommanded Product: 2-(4-(1-Hydroxy-4-(4-(hydroxydiphenylmethyl)piperidin-1-yl)butyl)phenyl)-2-methylpropanoic acid The following contents are mentioned in the article:

Inflammatory mediators may have a role in various lower urinary tract disorders. Histamine is known to induce significant increases in both the tension and frequency of spontaneous phasic contractions in both urothelium with lamina propria (U&LP) and detrusor muscle via the activation of H1 receptor in juvenile animal models. However, it is unclear whether age affects these contractile responses to histamine. This study assessed the histamine receptor subtypes mediating contraction in juvenile and adult porcine bladders and compared the urothelium with lamina propria and detrusor responses to histamine. Isolated tissue bath studies were conducted using strips of porcine U&LP and detrusor obtained from juvenile (6 mo) and adult (3 years) animals exposed to histamine receptor agonists and antagonists. Treatment with histamine (100μM) in U&LP of juvenile animals caused increases in baseline tension by 47.84 ± 6.52 mN/g (p < 0.001, n = 51) and by 50.76 ± 4.10 mN/g (p < 0.001, n = 55) in adult animals. Furthermore, the frequency of spontaneous phasic contractions was significantly enhanced in response to histamine in U&LP of both juvenile and adult tissues (p < 0.001 for both age groups). Treatment with an H2 agonist in U&LP of juvenile animals decreased baseline tension by 13.97 ± 3.45 mN/g (n = 12, p < 0.05), but had no effect in adult animals. Inhibition of H1 receptors resulted in significantly reduced contractile responses of U&LP and detrusor to histamine in both juvenile and adult animals (p < 0.05). Treatment with an H2 receptor antagonist significantly enhanced contractions in juvenile preparations (n = 10, p < 0.05) but had no effect in adult preparations (n = 8). In detrusor, treatment with histamine (100μM) in juvenile tissues showed a significantly higher increase in baseline tension of 19.10 ± 4.92 mN/g (n = 51) when compared to adult tissues exhibiting increases of 8.21 ± 0.89 mN/g (n = 56, p < 0.05). The increases in the baseline tension were significantly inhibited by the presence of H1 receptor antagonists in both juvenile and adult detrusor preparations Treatment with either the H2 receptor antagonist or agonist in detrusor had no effect on both juvenile and adult tissues. Therefore, the histamine receptor system may play an essential role in the maintenance of bladder function or in bladder dysfunction observed in some lower urinary tract disorders.

Anti-inflammatory treatment with a soluble epoxide hydrolase inhibitor attenuates seizures and epilepsy-associated depression in the LiCl-pilocarpine post-status epilepticus rat model was written by Shen, Yijun;Peng, Weifeng;Chen, Qinglan;Hammock, Bruce D.;Liu, Junyan;Li, Dongyang;Yang, Jun;Ding, Jing;Wang, Xin. And the article was included in Brain, Behavior, and Immunity in 2019.Recommanded Product: 1-(1-Propionylpiperidin-4-yl)-3-(4-(trifluoromethoxy)phenyl)urea The following contents are mentioned in the article:

This study aimed to investigate whether 1-trifluoromethoxyphenyl-3-(1-propionylpiperidin-4-yl) urea (TPPU), a soluble epoxide hydrolase inhibitor with anti-inflammatory effects, could alleviate spontaneous recurrent seizures (SRS) and epilepsy-associated depressive behaviors in the lithium chloride (LiCl)-pilocarpine-induced post-status epilepticus (SE) rat model. The rats were i.p. (IP) injected with LiCl (127 mg/kg) and pilocarpine (40 mg/kg) to induce SE. A video surveillance system was used to monitor SRS in the post-SE model for 6 wk (from the onset of the 2nd week to the end of the 7th week after SE induction). TPPU (0.1 mg/kg/d) was intragastrically given for 4 wk from the 21st day after SE induction in the SRS + 0.1 TPPU group. The SRS + PEG 400 group was given the vehicle (40% polyethylene glycol 400) instead, and the control group was given LiCl and PEG 400 but not pilocarpine. The sucrose preference test (SPT) and forced swim test (FST) were conducted to evaluate the depression-like behaviors of rats. Immunofluorescent staining, ELISA, and western blot anal. were performed to measure astrocytic and microglial gliosis, neuronal loss, and levels of soluble epoxide hydrolase (sEH), cytokines [tumor necrosis factor alpha (TNF-α), interleukin (IL)-1β, and IL-6], and cyclic adenosine monophosphate (cAMP)-response element binding protein (CREB). The frequency of SRS was significantly decreased at 6 wk and 7 wk after SE induction in the 0.1TPP U group compared with the SRS + PEG 400 group. The immobility time (IMT) evaluated by FST was significantly decreased, whereas the climbing time (CMT) was increased, and the sucrose preference rate (SPR) evaluated by SPT was in an increasing trend. The levels of sEH, TNF-α, IL-1β, and IL-6 in the hippocampus (Hip) and prefrontal cortex (PFC) were all significantly increased in the SRS + PEG 400 group compared with the control group; neuronal loss, astrogliosis, and microglial activation were also observed The astrocytic and microglial activation and levels of the pro-inflammatory cytokines in the Hip and PFC were significantly attenuated in the TPPU group compared with the SRS + PEG 400 group; moreover, neuronal loss and the decreased CREB expression were significantly alleviated as well. TPPU treatment after SE attenuates SRS and epilepsy-associated depressive behaviors in the LiCl-pilocarpine induced post-SE rat model, and it also exerts anti-inflammatory effects in the brain. Our findings suggest a new therapeutic approach for epilepsy and its comorbidities, especially depression.

Safety of fexofenadine and other second-generation oral antihistamines before and after the removal of the prescription requirement in Italy and other European countries: A real-world evidence study and systematicreview was written by Carnovale, Carla;Battini, Vera;Gringeri, Michele;Volonte, Marina;Uboldi, Maria Chiara;Chiarenza, Andrea;Passalacqua, Giovanni. And the article was included in World Allergy Organization Journal in 2022.Application In Synthesis of 2-(4-(1-Hydroxy-4-(4-(hydroxydiphenylmethyl)piperidin-1-yl)butyl)phenyl)-2-methylpropanoic acid The following contents are mentioned in the article:

The change from prescription to over-the-counter (OTC) status of oral antihistamines may raise concerns about drug safety due to the possibility of misuse/abuse. In most European countries, oral antihistamines are available without prescription, whereas in Italy, only <10-tablet packs are available OTC. To evaluate the safety profile of fexofenadine after OTC switch in Italy in a real-world setting, and to compare its safety profile to that of other European countries where larger pack sizes are available. To compare the safety of fexofenadine, cetirizine, and loratadine in Italy. To examine safety/efficacy across Europe with a systematic review. This case-by-case anal. used the US Food and Drug Administration (FDA) adverse event reporting system (FAERS) to extract data of the adverse events (AEs) related to fexofenadine, loratadine and cetirizine in Italy Jan. 2010-June 2020. The year 2016 was taken as the index date (removal of prescription requirement) for evaluation of the reporting trend of AEs of fexofenadine in Italy and make a comparison pre/post-OTC switch. A comparison of AEs with other European countries where fexofenadine is sold OTC in large packs >20 tablets (Belgium, Portugal, Switzerland, Finland, Hungary) was made. The rate at which an AE related to oral antihistamines occurred was estimated by calculation of the reporting rate (number of cases/[defined daily dose/1000 inhabitants per day]) on the basis of IQVIA sales data using the Italian Institute of Statistics database. A systematic review of the literature was also performed. There were 3760 reports of AEs with a suspected association with fexofenadine; of these, eight were reported from Italy. There was a slightly increasing trend per yr, in line with a general reporting trend of other drugs. In European countries where fexofenadine is available, the impact of OTC switch on AE reporting activity was negligible: from 2016, the reporting rate increased slightly and then normalized at 3.01, an incidence value similar to that recorded before the OTC switch (3.7 in 2015). Of 22 studies included in the systematic review, 18 (82%) pos. evaluated the OTC use of oral antihistamines, confirming an acceptable safety/tolerability profile. There was no difference in number of AEs reported for fexofenadine pre/post-OTC switch, indicating a similar safety profile. Spontaneous reporting systems are a valuable source of real-world data and support the OTC provision of oral antihistamines in Europe and fexofenadine in Italy, in addition to supporting the use of larger pack sizes in Italy.

Development of a robotics platform for automated multi-ionization mass spectrometry was written by Karki, Santosh;Meher, Anil K.;Inutan, Ellen D.;Pophristic, Milan;Marshall, Darrell D.;Rackers, Kevin;Trimpin, Sarah;McEwen, Charles N.. And the article was included in Rapid Communications in Mass Spectrometry in 2021.Safety of 2-(4-(1-Hydroxy-4-(4-(hydroxydiphenylmethyl)piperidin-1-yl)butyl)phenyl)-2-methylpropanoic acid The following contents are mentioned in the article:

Successful coupling of a multi-ionization automated platform with com. available mass spectrometers provides improved coverage of compounds in complex mixtures through implementation of new and traditional ionization methods. The versatility of the automated platform is demonstrated through coupling with mass spectrometers from two different vendors. Standards and complex biol. samples were acquired using electrospray ionization (ESI), solvent-assisted ionization (SAI) and matrix-assisted ionization (MAI). The MS® prototype automated platform samples from 96- or 384-well plates as well as surfaces. The platform interfaces with Thermo Fisher Scientific mass spectrometers by replacement of the IonMax source, and on Waters mass spectrometers with addnl. minor source inlet modifications. The sample is transferred to the ionization region using a fused-silica or metal capillary which is cleaned between acquisitions using solvents. For ESI and SAI, typically 1μL of sample solution is drawn into the capillary tube and for ESI slowly dispensed near the inlet of the mass spectrometer with voltage placed on the delivering syringe barrel to which the tubing is attached, while for SAI the sample delivery tubing inserts into the inlet without the need for high voltage. For MAI, typically, 0.2μL of matrix solution is drawn into the syringe before drawing 0.1μL of the sample solution and dispensing to dry before insertion into the inlet. A comparison study of a mixture of angiotensin I, verapamil, crystal violet, and atrazine representative of peptides, drugs, dyes, and herbicides using SAI, MAI, and ESI shows large differences in ionization efficiency of the various components. Solutions of a mixture of erythromycin and azithromycin in wells of a 384-microtiter well plate were mass analyzed at the rate of ∼1 min per sample using MAI and ESI. The authors report the anal. of bacterial extracts using automated MAI and ESI methods. Finally, the ability to perform surface anal. with the automated platform is also demonstrated by directly analyzing dyes separated on a thin-layer chromatog. (TLC) plate and compounds extracted from the surface of a beef liver tissue section. The prototype multi-ionization automated platform offers solid matrix introduction used with MAI, as well as solution introduction using either ESI or SAI. The combination of ionization methods extends the types of compounds which are efficiently ionized and is especially valuable with complex mixtures as demonstrated for bacterial extracts While coupling of the automated multi-ionization platform to Thermo and Waters mass spectrometers is demonstrated, it should be possible to interface it with most com. mass spectrometers.

Target, suspect and non-target screening analysis from wastewater treatment plant effluents to drinking water using collision cross section values as additional identification criterion was written by Hinnenkamp, Vanessa;Balsaa, Peter;Schmidt, Torsten C.. And the article was included in Analytical and Bioanalytical Chemistry in 2022.Computed Properties of C32H39NO4 The following contents are mentioned in the article:

The anthropogenic entry of organic micropollutants into the aquatic environment leads to a potential risk for drinking water resources and the drinking water itself. Therefore, sensitive screening anal. methods are needed to monitor the raw and drinking water quality continuously. Non-target screening anal. has been shown to allow for a more comprehensive investigation of drinking water processes compared to target anal. alone. However, non-target screening is challenging due to the many features that can be detected. Thus, data processing techniques to reduce the high number of features are necessary, and prioritization techniques are important to find the features of interest for identification, as identification of unknown substances is challenging as well. In this study, a drinking water production process, where drinking water is supplied by a water reservoir, was investigated. Since the water reservoir provides surface water, which is anthropogenically influenced by wastewater treatment plant (WWTP) effluents, substances originating from WWTP effluents and reaching the drinking water were investigated, because this indicates that they cannot be removed by the drinking water production process. For this purpose, ultra-performance liquid chromatog. coupled with an ion-mobility high-resolution mass spectrometer (UPLC-IM-HRMS) was used in a combined approach including target, suspect and non-target screening anal. to identify known and unknown substances. Addnl., the role of ion-mobility-derived collision cross sections (CCS) in identification is discussed. To that end, six samples (two WWTP effluent samples, a surface water sample that received the effluents, a raw water sample from a downstream water reservoir, a process sample and the drinking water) were analyzed. Pos. findings for a total of 60 substances in at least one sample were obtained through quant. screening. Sixty-five percent (15 out of 23) of the identified substances in the drinking water sample were pharmaceuticals and transformation products of pharmaceuticals. Using suspect screening, further 33 substances were tentatively identified in one or more samples, where for 19 of these substances, CCS values could be compared with CCS values from the literature, which supported the tentative identification. Eight substances were identified by reference standards In the non-target screening, a total of ten features detected in all six samples were prioritized, whereby metoprolol acid/atenolol acid (a transformation product of the two β-blockers metoprolol and atenolol) and 1,3-benzothiazol-2-sulfonic acid (a transformation product of the vulcanization accelerator 2-mercaptobenzothiazole) were identified with reference standards Overall, this study demonstrates the added value of a comprehensive water monitoring approach based on UPLC-IM-HRMS anal.

A study on prescription pattern of chronic kidney disease in tertiary care hospital was written by Saraswathi Pravallika, M.;Sampreethi, H.;Anusha, C. H.;Rohini, K.;Shete, Shivkumar. And the article was included in European Journal of Biomedical and Pharmaceutical Sciences in 2021.Electric Literature of C32H39NO4 The following contents are mentioned in the article:

The aim of the present investigation is to study the prescription pattern of chronic kidney disease in tertiary care hospital. The objective of the study was to study the prescription patterns of drugs used in chronic kidney disease and other comorbid conditions and to identify which drug is mostly prescribed at that hospital. To assess the rationality of prescription. To evaluate the medication adherence in CKD patients. The study on prescribing pattern definitely improves the quality of prescription writing, so study of drug prescribing pattern is relevant in the present scenario. To evaluate the prevalence of correct dosing in chronic kidney diseases depending on renal function estimation This is a retrospective, prospective observational study conducted over a period of six months. The study was conducted at Medicine ward of GLENEAGLES AWARE GLOBAL HOSPITAL LB.NAGAR. Patients who admitted to Nephrol. department of the hospital during a six- month period from Oct. 2021 to March 2021 are enrolled. CKD patients visiting the nephrologists are evaluated, diagnosed and prescribed with suitable therapy. All necessary details were collected from patient demographics, prescription chart, lab data, progress chart, medical records, doctor’s notes, nursing notes using a suitable designed data collection form. One hundred one patients were included in the project; with a mean age of 62.5. ± 18 years. More than half of patients were male, 77(76.2%). The mean BMI was 26 ± 1.15 kg/ m². The majority of patients were having normal weight 80 (79.2%), 15 (14.8%) patients had overweight, and obesity and only 6 (5.9%) patients were underweight. While 35 (34.6%) patients were smokers, 10 (9.9%) were ex-smokers and 56 (55.4%) patients were non- smokers. Anti- hypertensive agents are predominantly used among the patients. The most preferred options were beta blockers, calcium channel blockers and diuretics. Most of the physicians prescribed metoprolol (18.2%), amlodipine (38.3%), and cilnidipine (2%). Diuretics were the preferred option by the physician furosemide (92.3%), anti-platelets that are prescribed by the physicians are Aspirin (69.2%), clopidogrel (30.7%). Among the lipid lowering agents, atorvastatin (92.8%) was given to the most of the patients. sulbactam (20.4%), cefoperazone (20.4%), clarithromycin (10.25%), amoxycillin (10.25%) were mostly prescribed antibiotics in the study. The study concluded that most of the patients included in the study were suffering from chronic kidney disease. These may be due to their food habits, smoking, less exercise and poor health hygiene. The maximum number of patients was male; it may be due to smoking and alc. habits. Comorbidities such as hypertension, hyperglycemia, albuminuria, renal structure, and sex hormones, have been reported to have different effects on males and females. Thus, CKD progression may differ depending on sex. Early recognition with timely initiation of treatment in collaboration with nephrologists will improve the care for CKD patients. Thus, physicians and Nephrologists play an important outcome in patients with CKD.

Allergic Rhinitis is the most common of all atopic diseases. It is an important public health problem. It affects 20-25% of world population. The most common pharmacol. treatment options include intranasal corticosteroids, antihistamines, Leukotriene (LT) pathway inhibitor, α-adrenergic agonist, etc. Here, we aim to compare the efficacy of Levocetrizine and Fexofenadine and also, to compare the efficacy of Levocetrizine + Montelukast and fexofenadine + Montelukast in the treatment of allergic rhinitis in a tertiary hospital in Jharkhand, India. This observational follow up study was conducted in the department of pharmacol. & Therapeutics, among the patient attending out patient department of Ear, Nose and Throat (ENT) of Rajendra Institute of Medical Sciences, Ranchi, Jharkhand with prior approval from Institutional ethics committee. Observational, single centered, randomised, open label, four arm, parallel-group, comparative clin. study. 110 Patients were enrolled who have met the inclusion criteria for the study from the OPD of ENT Department of RIMS during the study period. The patients were placed in four groups and received their resp. medication orally once daily in the evening for period of two weeks. On the day of the participant enrolment, a written informed consent was taken from all the patient, medical history, phys. examination, patient′s symptoms recorded on TNSS Sheet (Total Nasal Symptoms Score) and demonstrated to subject how to note and hand over the TNSS Sheet. After Completion of study on 15^th day, phys. examination and vital sign were checked; recording on sheet was collected. Mean changes in TNSS at the end of 24 h, 1^st and 2^nd week and comparison of effect of drugs with and without montelukast with the help of Total Nasal Score were calculated by using Statistical Package for the Social Sciences, IBM SPSS 20. The data was tabulated as mean ± standard deviation (Mean SD). Paired′t′ test was used to compare mean changes in TNSS Score before and after treatment. Out of total 110 enrolled patients, 98 completed the study, 4 patients not completed 2weeks treatment, 2 patients had change in disease pattern and 6 patient lost to follow up. The demog. characteristics of four groups were compared for age and sex. All groups had female predominance. The baseline Total Nasal Symtoms Score (TNSS) were comparable among the all four treatment groups. The mean TNSS was significantly reduced in all four study groups. After 1day of treatment change in TNSS have in following order Group C > Group D >Group A >Group B. Maximum change was observed in Levocetrizine & Montelukast combination group and min. change was observed in Fexofenadine group. Same order of change in TNSS was observed in study after 1 wk and 2weeks of treatment. So in our study Levocetrizine have been found better than fexofenadine in decreasing TNSS in allergic rhinitis patient. Similarly Levocetirizine-Montelukast combination decreases TNSS more than Fexofenadine-Montelukast combination. All the study drugs have shown significant improvement in quality of life of Allergic rhinitis patients. Levocetrizine has shown more effectiveness than Fexofenadine when used alone in allergic rhinitis patient.
