组织蛋白酶 K (Cat K) 是一种主要的半胱氨酸蛋白酶和在破骨细胞中表达的高效胶原酶。Cat K 抑制剂是治疗骨质疏松症的抗吸收剂。以先导化合物1x为例的新型组织蛋白酶 K 抑制剂支架被用作设计和合成总共 61 种以前未曾报道过的衍生物的模板。探索性构效关系分析确定了有效的 Cat K 抑制剂A22,其对Cat K的 IC 50值为 0.44 μM 。铅化合物1x. 表面等离子体共振分析证实了A22与 Cat K的体外结合。分子对接研究表明, A22在 Cat K 的活性口袋内有几个有利的相互作用位点。此外, A22还在体外阻断了活性破骨细胞并增加了斑马鱼的脊柱骨密度,其中它显示出高于市售治疗性骨代谢剂依替膦酸二钠的活性。A22代表了一种非常有前途的先导化合物,可用于开发用作 Cat K 的正构抑制剂的新型抗吸收剂。

Benzimidazole and piperazines are the important pharmacophores in the structures of many antifungal compounds. Further, the phenylmethanone are also a unique class of compounds whose antifungal profile is not much exploited. So to exploit their antifungal potential we have selected these three combinations and framed the novel parent structure for our research work. In this study a novel series of benzimidazoles derivatives was synthesized by microwave irradiation and characterized by 1H NMR, 13C NMR, Infra Red (IR), and Mass Spectroscopy (MS), and by elemental analysis. The screening of compound for in vitro (turbidimetric method) antifungal activity against C.albicans revealed activity in many of the compounds as comparable to that of ketoconazole.

Twelve novel compounds of 2‐acetyl‐1H‐benzimidazole oxime‐ethers and 2‐acetyl‐6‐chloro‐1H‐benzimidazole oxime‐ethers were synthesized with o‐phenylenediamine (or 4‐chloro‐o‐phenylenediamine), 2‐hydroxypropyl acid, alkoxy (or benzyloxy) amines hydrochloride as starting materials. The structures of the target compounds were characterized by IR, 1H NMR spectra and elemental analyses. The in vitro fungicidal

of 2-acetyl benzimidazoles ( 4a – d ) with different aromatic aldehydes, which in turn were obtained by the oxidation of 2-(α-hydroxy)ethyl benzimidazoles ( 3a – d ) prepared by the reaction of o -phenylenediamines ( 1a – d ) with α-hydroxy propionic acid 2 . The synthesized compounds were characterized by their IR, 1 H NMR and MS analyses. These compounds were screened for their antibacterial and antifungal
