Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent， Quality Control of: Ethyl N-benzylpiperidine-4-carboxylate, Which mentioned a new discovery about 24228-40-8

The modification of sodium bis(2-methoxyethoxy)aluminum hydride (SMEAH) with pyrrolidine provided a highly selective reducing agent to transform N-benzyl-4-ethoxycarbonylpiperidine into N-benzyl-4-formylpiperidine 1 under mild conditions. However, this simple modification led to a significant amount of N-benzyl-4-(pyrrolidin-1-ylmethyl)piperidine 4 due to overreduction of an intermediate. Our extensive research revealed that an alkaline base such as potassium tert-butoxide could suppress the formation of the by-product to give the desired aldehyde, enabling us to establish a viable synthetic process for a key intermediate of donepezil hydrochloride. The potential applications of this reagent are also described.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 24228-40-8, help many people in the next few years.Quality Control of: Ethyl N-benzylpiperidine-4-carboxylate

Synthetic Route of 126501-70-0, In heterogeneous catalysis, the catalyst is in a different phase from the reactants. At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 126501-70-0, name is 1-(2,2,2-Trifluoroacetyl)piperidine-4-carboxylic acid. In an article，Which mentioned a new discovery about 126501-70-0

We previously reported the discovery of 4-[(Z)-(4-bromophenyl)(ethoxyimino)methyl]-1?-[(2,4-dimethyl-3 -pyridinyl)carbonyl]-4?-methyl-1,4?-bipipefidine N-oxide 1 (SCH 351125) as an orally bioavailable human CCR5 antagonist for the treatment of HIV-1 infection. Herein, we describe in detail the discovery of 1 from our initial lead compound as well as the synthesis and SAR studies directed toward optimization of substitution at the phenyl, oxime, and right-hand side amide groups in the oximino-piperidino-piperidine series. Substitutions (4-Br, 4-CF3, 4-OCF3, 4-SO2Me, and 4-Cl) at the phenyl group are well-tolerated, and small alkyl substitutions (Me, Et, nPr, iPr, and cyclopropyl methyl) at the oxime moiety are preferred for CCR5 antagonism. The 2,6-dimethylnicotinamide N-oxide moiety is the optimal choice for the right-hand side. Several compounds in this series, including compound 1, exhibited excellent antiviral activity in vitro. Compound 1, which has a favorable pharmacokinetic profile in rodents and primates, excellent oral bioavailability, and potent antiviral activity against a wide range of primary HIV-1 isolates, is a potentially promising new candidate for treatment of HIV-1 infection.

Overexpression of AKT has an antiapoptotic effect in many cell types, and expression of dominant negative AKT blocks the ability of a variety of growth factors to promote survival. Therefore, inhibitors of AKT kinase activity might be useful as monotherapy for the treatment of tumors with activated AKT. Herein, we describe our lead optimization studies culminating in the discovery of compound 3g (GSK690693). Compound 3g is a novel ATP competitive, pan-AKT kinase inhibitor with IC50 values of 2, 13, and 9 nM against AKT1, 2, and 3, respectively. An X-ray cocrystal structure was solved with 3g and the kinase domain of AKT2, confirming that 3g bound in the ATP binding pocket. Compound 3g potently inhibits intracellular AKT activity as measured by the inhibition of the phosphorylation levels of GSK3beta. Intraperitoneal administration of 3g in immunocompromised mice results in the inhibition of GSK3beta phosphorylation and tumor growth in human breast carcinoma (BT474) xenografts.

In order to target behavioral and psychological symptoms of dementia (BPSD), we used molecular modeling-assisted design to obtain novel multifunctional arylsulfonamide derivatives that potently antagonize 5-HT 6/7/2A and D2 receptors, without interacting with M 1 receptors and hERG channels. In vitro studies confirmed their antagonism of 5-HT7/2A and D2 receptors and weak interactions with key antitargets (M1R and hERG) associated with side effects. Marked 5-HT6 receptor affinities were also observed, notably for 6-fluoro-3-(piperidin-4-yl)-1,2-benzoxazole derivatives connected by a 3-4 unit alkyl linker with mono- or bicyclic, lipophilic arylsulfonamide moieties. N-[4-[4-(6-Fluoro-1,2-benzoxazol-3-yl)piperidin-1-yl]butyl] benzothiophene-2-sulfonamide (72) was characterized in vitro on 14 targets and antitargets. It displayed dual blockade of 5-HT6 and D2 receptors and negligible interactions at hERG and M1 receptors. Unlike reference antipsychotics, 72 displayed marked antipsychotic and antidepressant activity in rats after oral administration, in the absence of cognitive or motor impairment. This profile is particularly attractive when targeting a fragile, elderly BPSD patient population.
