Kinetics and mechanism of counterionic salt-catalysed piperidinolysis of anionic phenyl salicylate in the presence of cationic-nonionic mixed micelles

The quantitative correlation of counterion-affinity to aqueous hexadecyltrimethylammonium bromide (HDAB, cationic micelles/nanoparticles) and the counterion-induced HDAB micellar growth, in the presence of different amounts of poly(ethylene glycol hexadecyl ether) (C16E20, nonionic surfactant), was achieved by the use of a semi-empirical kinetic (SEK) method. The values of the ratio of cationic HDAB, as well as mixed HDAB-C16E20, micellar binding constants of X and Br, K-X/K-Br (= K-X(Br) or R-X(Br)) for X = 4-ClC6H4CO2-, were obtained by the SEK method. The concentration range (0.006-0.015 M) of pure HDAB was found to have no influence on the values of K-X(Br) or R-X(Br). These observations were also recorded upon addition of a nonionic surfactant, C16E20, in an aqueous solution of HDAB. The mean value of K-X(Br) or R-X(Br) obtained in the presence of pure HDAB (K-X(Br) or R-X(Br) = 50.3) is 2.3 times larger than that in the presence of mixed HDAB-C16E20 (K-m(X)Br or R-m(X)Br = 21.7). From rheometric measurements of aqueous HDA(+)/4-ClC6H4CO2- with 0.015 M HDAB, single symmetric maxima (at both 25 and 35 degrees C) were obtained at [4-ClC6H4CO2Na] = 0.03 M. This is evidence for the existence of wormlike micelles/nanoparticles. However, the absence of a maximum in rheometric data for aqueous HDA(+)/C16E20/4-ClC6H4CO2- with 0.015 M HDAB and 0.006 M C16E20 at various [4-ClC6H4CO2Na] revealed the existence of spherical micelles.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 106-52-5, in my other articles.

In silico and BSA binding study of some new biological analogs of 1,2,4-triazole pendant with azinane through microwave and conventional synthesis

Microwave and conventional techniques were employed to synthesize a novel array of compounds 7a-g with 1,2,4-triazole and piperidine rings having great biological importance. The microwave assisted method has a better operational scope with respect to time and yield comparative to the conventional method. H-1-NMR, C-13-NMR and IR techniques were employed to justify the structure of synthesized compounds. The antioxidant, butyrylcholinesterase inhibition and urease inhibition potential of every synthesized compound was evaluated. Every member of the synthesized series was found potent against mentioned activities. Compound 7g was the most active anti-urease agent having IC50 (mu M) value 16.5 +/- 0.09 even better than the thiourea with an IC50 (mu M) value of 24.3 +/- 0.24. The better urease inhibition potential of 7g was also elaborated and explained by docking and bovine serum albumin (BSA) binding studies.

Diversity-oriented synthesis derived indole based spiro and fused small molecules kills artemisinin-resistant Plasmodium falciparum

BackgroundDespite numerous efforts to eradicate the disease, malaria continues to remain one of the most dangerous infectious diseases plaguing the world. In the absence of any effective vaccines and with emerging drug resistance in the parasite against the majority of anti-malarial drugs, the search for new drugs is urgently needed for effective malaria treatment.MethodsThe goal of the present study was to examine the compound library, based on indoles generated through diversity-oriented synthesis belonging to four different architecture, i.e., 1-aryltetrahydro/dihydro-beta -carbolines and piperidine/pyrrolidine-fused indole derivatives, for their in vitro anti-plasmodial activity. Trifluoroacetic acid catalyzed transformation involving tryptamine and various aldehydes/ketones provided the library.ResultsAmong all the compounds screened, 1-aryltetrahydro-beta -carbolines 2 and 3 displayed significant anti-plasmodial activity against both the artemisinin-sensitive and artemisinin-resistant strain of Plasmodium falciparum. It was observed that these compounds inhibited the overall parasite growth in intra-erythrocytic developmental cycle (IDC) via reactive oxygen species-mediated parasitic death and thus could be potential anti-malarial compounds.ConclusionOverall the compounds 2 and 3 identified in this study shows promising anti-plasmodial activity that can kill both artemisinin-sensitive and artemisinin-resistant strains of P. falciparum.

Electric Literature of 5570-77-4, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 5570-77-4 is helpful to your research.

Structure-Based Drug Discovery of N-((R)-3-(7-Methyl-1H-indazol-5-yl)-1-oxo-1-(((S)-1-oxo-3-(piperidin-4-yl)-1-(4-(pyridin-4-yl)piperazin-1-yl)propan-2-yl)amino)propan-2-yl)-2 ‘-oxo-1 ‘,2 ‘-dihydrospiro[piperidine-4,4 ‘-pyrido[2,3-d][1,3]oxazine]-1-carboxamide (HTL22562): A Calcitonin Gene-Related Peptide Receptor Antagonist for Acute Treatment of Migraine

Structure-based drug design enabled the discovery of 8, HTL22562, a calcitonin gene-related peptide (CGRP) receptor antagonist. The structure of 8 complexed with the CGRP receptor was determined at a 1.6 angstrom resolution. Compound 8 is a highly potent, selective, metabolically stable, and soluble compound suitable for a range of administration routes that have the potential to provide rapid systemic exposures with resultant high levels of receptor coverage (e.g., subcutaneous). The low lipophilicity coupled with a low anticipated clinically efficacious plasma exposure for migraine also suggests a reduced potential for hepatotoxicity. These properties have led to 8 being selected as a clinical candidate for acute treatment of migraine.

Synthesis of novel spiropiperidine derivatives and their antimicrobial and antioxidant activities

A series of novel spiro-piperidinyl pyrazolones are synthesized by the reaction of N-Boc protected ethyl nipecotate with heteroaryl and alkyl aldehydes in presence of lithium diisopropyl amide (LDA) to yield corresponding beta-hydroxy ester, followed by MnO2 oxidation to give beta-keto ester. Further reaction of beta-keto ester with hydrazine hydrate results in the formation of spiro-piperidinyl pyrazolone scaffold 5a-d which upon N-benzylation followed by deprotection yields compounds 7a-s. The pyrazolone-NH group has been alkylated in compound 5a with ethyl chloroacetate followed by hydrolysis and amide coupling to afford compounds 9a-d. The furan ring in compound 5a is oxidized to carboxylic acid with KMnO4 and coupled with amines to prepare amide derivatives 11a-c. All the synthesized compounds are evaluated for their in vitro antibacterial and antioxidant activity. Compounds 7a-d and 7g-s are found to possess high antibacterial activity and compounds 7a,7b, 9a, 9b, 11a and 11c are found to be potent antioxidants.

Sample Flow Rate Scan in Electrospray Ionization Mass Spectrometry Reveals Alterations in Protein Charge State Distribution

Sample flow rate is one of the parameters that influence the sensitivity of electrospray ionization (ESI) mass spectrometry. By varying the sample flow rate, initial droplets of different sizes can be generated. Protein molecules in small droplets may form gas-phase ions earlier than the ones in large droplets. Here, we have systematically studied the influence of sample flow rate on the ESI charge state distributions (CSDs) of model proteins. A dedicated programmable sample flow rate scanner was used to infuse protein samples at different flow rates into a mass spectrometer. The synergistic influence of sample flow rate and various electrolytes (ammonium acetate, ammonium bicarbonate, ammonium formate, and piperidine) was studied. Significant alterations to the CSDs with increasing flow rate were observed. For example, in the presence of ammonium acetate, at low flow rates, lower charge states of proteins showed high intensities, while at high flow rates, ions related to higher charge states of proteins dominated the spectra. On the other hand, in the presence of piperidine, a significant reduction in the ion currents of all charge states was observed during the flow rate scan. Our observations suggest that at low flow rates the protein molecules follow a charged residue model of ionization mechanism, and at high flow rates-due to structural changes in protein molecules in large ESI droplets-the charged residue and chain ejection models can possibly coexist. We propose the use of sample flow rate scan as a way to reveal the influence of flow rate on the CSDs of the studied proteins.

Epidemiological Study of Multidrug Resistant and Efficiency of Piperidine Compounds against Hospital Acquired Opportunistic Pathogens in Tamil Nadu, India

The pathogens attained through nosocomial infection exhibit a higher degree of antibiotic resistance due to constant exposure to drug therapy. There is a need to develop alternate therapeutics for treating these resistant pathogens. Objective: The objective of this study is to isolate pathogens from hospital-acquired infection to determine its epidemiology and multidrug resistance. In this study, urine and swab samples (354) were obtained from hospitalized patients with no prior infection history. For screening antibiotic resistance among the isolates, 15 antibiotics were used in this study, and also various piperidine compounds were used to evaluate the minimum inhibitory concentration against the isolates. Among them, 160 reported positive for the presence of Staphylococcus species (37), Salmonella species (23), Pseudomonas species (27), Proteus species (21), E. coli (34) and Klebsiella species (18). Mostly, all the pathogens obtained from clinical cases show high antibiotic resistance. The highest percentage of resistance was recorded against amoxicillin and penicillin (98%). The least rate of resistance was noticed against gentamycin (42%). Like antibiotics, the test compounds exhibited better minimum inhibitory concentration (MIC) against the test isolates. The MIC of the compounds against Staphylococcus species and E. coli was discovered to be higher when compared to Klebsiella species and Salmonella species. The piperidine compounds that were used as alternatives showed promising susceptibility towards pathogens.

Understanding the Conformational Behavior of Fluorinated Piperidines: The Origin of the Axial-F Preference

Gaining an understanding of the conformational behavior of fluorinated compounds would allow for expansion of the current molecular design toolbox. In order to facilitate drug discovery efforts, a systematic survey of a series of diversely substituted and protected fluorinated piperidine derivatives has been carried out using NMR spectroscopy. Computational investigations reveal that, in addition to established delocalization forces such as charge-dipole interactions and hyperconjugation, solvation and solvent polarity play a major role. This work codifies a new design principle for conformationally rigid molecular scaffolds.

Development of Highly Efficient Organocatalytic Reaction toward Practical Total Synthesis of ent-Quinine

Recently, cinchona alkaloids such as quinine and quinidine were re-focused as next generation organocatalysts. Therefore, practical total syntheses of enantiomers of these alkaloids are required in current chemical society. Thus, efficient protocol for preparation of C4-alkyl substituted chiral piperidines using secondary amine catalyzed formal aza[3+3]cycloaddition reaction using aliphatic alpha,beta-unsaturated aldehydes and thiomalonamate derivatives were discovered as key step in total synthesis. In our reaction system, thiomalonamate is excellent nucleophile, and the addition of suitable acid and it’s amounts are important factor for the acceleration effect in organocatalytic reaction. These efforts lead to only 0.1 mol% catalyst loading in multi-gram scale synthesis for suitable reaction time.
