And the article contained the following:

High-performance thin-layer chromatog. (HPTLC)-densitometric method of haloperidol (HP) and its two metabolites (reduced haloperidol [RHP], 4-(4-chlorophenyl)-4-hydroxypiperidine [CPHP]) from human plasma has been developed by use of mobile-phase additives. The influence of the type of inorganic/organic additive on the retention of the studied compounds was evaluated. The chromatog. process was carried out with traditional mobile phase modifiers and 1-alkyl-imidazolium ionic liquid as separation enhancers, in the presence of chlorpromazine as internal standard 1-Ethyl-3-methylimidazolium tetrafluoroborate ([emim][BF4]) ionic liquid offered good selectivity in comparison with traditional mobile phase additives. The studied drugs were well distributed as the RF values were 0.31 for chlorpromazine hydrochloride (CPZ), 0.38 for HP, 0.44 for CPHP, and 0.58 for RHP, resp., with no apparent broadening and overlapping of spots. The test compounds were extracted using acetonitrile as precipitation agent. The identity of the bands from human plasma was addnl. confirmed by rapid and contamination-free CAMAG thin-layer chromatog.-mass spectrometry (TLC-MS) interface. The limit of detection (LOD) values obtained by densitometry scanning were 0.1807, 0.3158, and 0.3924μg spot-1 (for HP, RHP, and CPHP), whereas the limit of quantification (LOQ) values for the presented method were 0.5476, 0.9570, and 1.1892μg spot-1 (for HP, RHP, and CPHP). Recovery values of all tested compounds were in the range from 95.43% to 99.60% (intra-day) and 96.13% to 103.18% (inter-day);%RSD did not exceed the value of 5%. The results confirm the pos. effect of ionic liquids in the separation process related to their silanol blocking properties and their suitability for use in thin-layer chromatog./mass spectrometry method. The experimental process involved the reaction of 4-(4-Chlorophenyl)piperidin-4-ol(cas: 39512-49-7).Category: piperidines

On March 9, 2022, Rodrigalvarez, Jesus; Reeve, Luke A.; Miro, Javier; Gaunt, Matthew J. published an article.Formula: C11H14ClNO The title of the article was Pd(II)-Catalyzed Enantioselective C(sp3)-H Arylation of Cyclopropanes and Cyclobutanes Guided by Tertiary Alkylamines. And the article contained the following:

Here, a palladium-catalyzed enantioselective C(sp3)-H arylation of aminomethyl-cyclopropanes I [R = H, Me, (CH2)2OMe, 4-ClC6H44; R1 = NMe2, NEt2, N-piperidinyl, etc.; Ar = Ph, 2-naphthyl, 6-Cl-3-pyridinyl, etc.; n = 1] and -cyclobutanes I [n = 2] with aryl boronic acids was reported. A range of native tertiary alkylamine groups were able to direct C-H cleavage and forge carbon-aryl bonds on the strained cycloalkanes framework as single diastereomers and with excellent enantiomeric ratios. Central to the success of this strategy was the use of a simple N-acetyl amino acid ligand, which not only controls the enantioselectivity but also promotes γ-C-H activation of over other pathways. Computational anal. of the cyclopalladation step provided an understanding of how enantioselective C-H cleavage occurred and revealed distinct transition structures to our previous work on enantioselective desymmetrization of N-iso-Bu tertiary alkylamines. This straightforward and operationally simple method simplified the construction of functionalized aminomethyl-strained cycloalkanes, which was believed will find widespread use in academic and industrial settings relating to the synthesis of biol. active small mols. The experimental process involved the reaction of 4-(4-Chlorophenyl)piperidin-4-ol(cas: 39512-49-7).Formula: C11H14ClNO

On August 15, 2016, Etukala, Jagan R.; Zhu, Xue Y.; Eyunni, Suresh V. K.; Onyameh, Edem K.; Ofori, Edward; Bricker, Barbara A.; Kang, Hye J.; Huang, Xi-Ping; Roth, Bryan L.; Ablordeppey, Seth Y. published an article.Computed Properties of 39512-49-7 The title of the article was Development of CNS multi-receptor ligands: Modification of known D2 pharmacophores. And the article contained the following:

Several known D2 pharmacophores have been explored as templates for identifying ligands with multiple binding affinities at dopamine and serotonin receptors considered as clin. relevant receptors in the treatment of neuropsychiatric diseases. This approach has resulted in the identification of ligands that target multiple CNS receptors while avoiding others associated with deleterious effects. Three compounds including I may have potential for further development as antipsychotic agents as they favorably interact with the clin. relevant receptors including D2R, 5-HT1AR, and 5-HT7R. The authors have also identified the pair of compounds I and II as high affinity D2R ligands with and without SERT binding affinities, resp. These differential binding profiles endow the pair with the potential for evaluating SERT contributions to antipsychotic drug activity in animal behavioral models. In addition, compound I has no significant affinity for 5-HT2CR and binds only moderately to the H1R, suggesting it may not induce weight gain or sedation when used clin. Taken together, compound I displays an interesting pharmacol. profile that necessitates the evaluation of its functional and in vivo effects in animal models which are currently ongoing. The experimental process involved the reaction of 4-(4-Chlorophenyl)piperidin-4-ol(cas: 39512-49-7).Computed Properties of 39512-49-7

Part 2: Improving the profile of a series of 1,3-bis(aryloxy)benzene derivatives. And the article contained the following:

The initial lead compound was modified to improve its metabolic stability. The resulting compound showed excellent metabolic stability in rat and human liver microsomes. The authors subsequently designed and synthesized compound N-[3-[4-(aminocarbonyl)phenoxy]-5-(4-fluorophenoxy)phenyl]-4-(4-chlorophenyl)-4-hydroxy-1-piperidinecarboxamide (I), which showed improved S1P2 antagonist activity and good metabolic stability. The subsequent introduction of a carboxylic acid moiety into I resulted in 4-[3-(4-fluorophenoxy)-5-[[[4-(4-fluorophenyl)-4-hydroxy-1-piperidinyl]carbonyl]amino]phenoxy]benzoic acid (II), which showed potent antagonist activity towards S1P2 with a much smaller species difference between human S1P2 and rat S1P2. Compound II also showed good metabolic stability and an improved safety profile compared with compound I.

On January 1, 2014, Gitto, Rosaria; De Luca, Laura; Ferro, Stefania; Scala, Angela; Ronsisvalle, Simone; Parenti, Carmela; Prezzavento, Orazio; Buemi, Maria Rosa; Chimirri, Alba published an article.Formula: C11H14ClNO The title of the article was From NMDA receptor antagonists to discovery of selective σ2 receptor ligands. And the article contained the following:

Following previous studies focused on the search for new mols. targeting GluN2B-containing NMDA, a small series of 1-(1H-indol-3-yl)-2-(4-phenylpiperidin-1-yl)ethanone derivatives has been synthesized by using Microwave Assisted Organic Synthesis (MAOS). Given that GluN2B ligands frequently exert off-target effects we also tested their affinity towards sigma receptors. Binding assay revealed that only the 1-(5-hydroxy-1H-indol-3-yl)-2-(4-phenylpiperidin-1-yl)ethanone (7a) retained GluN2B affinity. Interestingly, the 5-methoxyindoles 5a and 6a were efficient and selective ligands toward σ2 receptor (Ki values of 10 nM and 20 nM, resp.). Thus, in this case the discovery of new σ2 receptor selective ligands was an unexpected result emerging from the screening of cross-activity against other CNS receptors. The experimental process involved the reaction of 4-(4-Chlorophenyl)piperidin-4-ol(cas: 39512-49-7).Formula: C11H14ClNO

On August 6, 2020, U. Dighe, Shashikant; Julia, Fabio; Luridiana, Alberto; Douglas, James J.; Leonori, Daniele published an article.HPLC of Formula: 39512-49-7 The title of the article was A photochemical dehydrogenative strategy for aniline synthesis. And the article contained the following:

Chem. reactions that reliably join two mol. fragments together (cross-couplings) are essential to the discovery and manufacture of pharmaceuticals and agrochems.1,2. The introduction of amines onto functionalized aromatics at specific and pre-determined positions (ortho vs. meta vs. para) is currently achievable only in transition-metal-catalyzed processes and requires halogen- or boron-containing substrates3-6. The introduction of these groups around the aromatic unit is dictated by the intrinsic reactivity profile of the method (electrophilic halogenation or C-H borylation) so selective targeting of all positions is often not possible. Here we report a non-canonical cross-coupling approach for the construction of anilines, exploiting saturated cyclohexanones as aryl electrophile surrogates. Condensation between amines and carbonyls, a process that frequently occurs in nature and is often used by (bio-)organic chemists7, enables a predetermined and site-selective carbon-nitrogen (C-N) bond formation, while a photoredox- and cobalt-based catalytic system progressively desaturates the cyclohexene ring en route to the aniline. Given that functionalized cyclohexanones are readily accessible with complete regiocontrol using the well established carbonyl reactivity, this approach bypasses some of the frequent selectivity issues of aromatic chem. We demonstrate the utility of this C-N coupling protocol by preparing com. medicines and by the late-stage amination-aromatization of natural products, steroids and terpene feedstocks. The experimental process involved the reaction of 4-(4-Chlorophenyl)piperidin-4-ol(cas: 39512-49-7).HPLC of Formula: 39512-49-7

Rampa, Angela; Bartolini, Manuela; Pruccoli, Letizia; Naldi, Marina; Iriepa, Isabel; Moraleda, Ignacio; Belluti, Federica; Gobbi, Silvia; Tarozzi, Andrea; Bisi, Alessandra published an article in 2018, the title of the article was Exploiting the chalcone scaffold to develop multifunctional agents for Alzheimer′s disease.Reference of 4-(4-Chlorophenyl)piperidin-4-ol And the article contains the following content:

Alzheimer′s disease still represents an untreated multifaceted pathol., and drugs able to stop or reverse its progression are urgently needed. In this paper, a series of naturally inspired chalcone-based derivatives was designed as structural simplification of our previously reported benzofuran lead compound, aiming at targeting both acetyl (AChE)- and butyryl (BuChE) cholinesterases that, despite having been studied for years, still deserve considerable attention. In addition, the new compounds could also modulate different pathways involved in disease progression, due to the peculiar trans-a,β-unsaturated ketone in the chalcone framework. All mols. presented in this study were evaluated for cholinesterase inhibition on the human enzymes and for antioxidant and neuroprotective activities on a SH-SY5Y cell line. The results proved that almost all the new compounds were low micromolar inhibitors, showing different selectivity depending on the appended substituent; some of them were also effective antioxidant and neuroprotective agents. In particular, compound 4, endowed with dual AChE/BuChE inhibitory activity, was able to decrease ROS formation and increase GSH levels, resulting in enhanced antioxidant endogenous defense. Moreover, this compound also proved to counteract the neurotoxicity elicited by Aβ1-42 oligomers, showing a promising neuroprotective potential.

And the article contained the following:

Whole-food-based strategies to prevent metabolic diseases are growing interests. Agrocybe cylindracea (AC) is a major edible mushroom with high values of nutrition, but little is known about its health benefits as a portion of whole food. Diet-induced obese, C57BL/6J mice are fed an high-fat diet (HFD) with or without AC (3% or 5%, weight/weight in the diet) for 9 wk. The results show that dietary AC reduced body weight, adipose accumulation, impairment of glucose tolerance, lipid levels, and liver injury in HFD-fed mice. Moreover, AC not only prevents HFD-induced gut disorder, as indicates by the enriched probiotic Bifidobacterium and reduced endotoxin-bearing Proteobacteria, but also improve the lipopolysaccharide (LPS) level and gut tissue structure. Fecal metabolites such as harmine and harmanine are also remarkably altered by AC. Spearman′s correlation anal. reveals that the AC-altered microbes and metabolites are strongly correlated with obesity-related indexes. These findings suggest that dietary AC prevents HFD-induced obesity and its complications in association with modulating gut microbiota and associated fecal metabolites. The experimental process involved the reaction of 4-(4-Chlorophenyl)piperidin-4-ol(cas: 39512-49-7).Reference of 4-(4-Chlorophenyl)piperidin-4-ol
