employed to study interactions within the AChE active site. In silico ADME study was performed to estimate pharmacokinetic parameters. Based on computational studies, some analogues were synthesized and subjected to pharmacological evaluation involving antioxidant activity, toxicity and memory model studies in animals followed by detailed mechanistic in vitro cholinesterase inhibition study. Amongst the
gel (P2O5/SiO2) has been used as an efficient and reusable catalyst for the one‐pot pseudo four‐componentsynthesis of 2,4,5‐trisubstituted imidazoles from benzil or benzoin, aldehydes, and ammonium acetate. It was also used for four‐component preparation of 1,2,4,5‐tetrasubstitutedimidazoles from benzil or benzoin, aldehydes, primary amine, and ammonium acetate under thermal solvent‐free conditions
负载在硅胶(P 2 O 5 / SiO 2)上的五氧化二磷已被用作一种高效且可重复使用的催化剂,用于由苯甲腈或安息香,醛,和醋酸铵。它也可在无热溶剂的条件下用于由苄基或安息香,醛,伯胺和乙酸铵四组分制备1,2,4,5-四取代的咪唑。这种新方法的显着特征是高转化率,更清洁的反应,简单的实验和后处理程序,并且催化剂可以轻松地从反应混合物中分离出来并重复使用几次,而不会损失其活性。

In a previous study, target based screening was carried out for inhibitors of β-hematin (synthetic hemozoin) formation, and a series of triarylimidazoles were identified as active against Plasmodium falciparum. Here, we report the subsequent synthesis and testing of derivatives with varying substituents on the three phenylrings for this series. The results indicated that a 2-hydroxy-1,3-dimethoxy
The efficient construction of 2,4,5-trisubstituted imidazoles, through a copper-mediated three-component reaction involving ketones, aldehydes, and Me3SiN3, has been developed.
