been concerned with the design of selective inhibitors of heme oxygenases (HO‐1 and HO‐2). The majority of these were based on a four‐carbon linkage of an azole, usually an imidazole, and an aromatic moiety. In the present study, we designed and synthesized a series of inhibition candidates containing a shorter linkage between these groups, specifically, a series of 1‐aryl‐2‐(1H‐imidazol‐1‐yl/1H‐1
medicinal chemistry due to the wide spectrum of biologicalactivities and mainly antifungal activity of 1,2,4-triazole derivatives. The main mechanism of antifungal action of the latter is inhibition of 14-alpha-demethylase enzyme (CYP51). The current study presents synthesis and evaluation of eight triazole derivatives for their antimicrobialactivity. Docking studies to elucidate the mechanism of

compositions comprising an effective amount of said compounds either alone or in combination with other chemotherapeutic agents, and methods useful for treating or preventing cancer and for inhibiting tumour tissue growth. These compounds attenuate the oxidative damage associated with increased heme-oxygenase activity and can reduce cell proliferation in transformed cells. In addition, the described compounds and compositions are useful as neuroprotectants and for treating or preventing neurodegenerative disorders and other diseases of the central nervous system.

further tested and found potent competitive cholinesterase inhibitorsvia enzyme kinetics study. The active derivatives showed negligible toxicity in in vitro cytotoxicity tests. Molecular modeling studies predicted that these derivatives were druglike, could penetrate blood-brain barrier, and tightly bind to cholinesterase active site making key interactions via the imidazole moiety at protonated state
胆碱酯酶抑制在对抗阿尔茨海默病等神经退行性疾病方面非常重要。最近的发现强调了咪康唑及其衍生物对胆碱酯酶的功效和潜力,唑类抗真菌剂已成为人们关注的焦点。在这项研究中,我们使用体外和计算机方法评估了针对乙酰胆碱酯酶和丁酰胆碱酯酶的唑类库,以确定有效的抑制剂。咪唑衍生物获得了低微摩尔 IC 50值,进一步测试并通过酶动力学研究发现了有效的竞争性胆碱酯酶抑制剂。活性衍生物在体外显示出可忽略不计的毒性细胞毒性试验。分子模型研究预测,这些衍生物具有药物样作用,可以穿透血脑屏障,并通过质子化状态的咪唑部分与胆碱酯酶活性位点紧密结合,形成关键的相互作用。因此,目前的研究确定了具有轻微毒性和潜在进入中枢神经系统的强效和竞争性胆碱酯酶抑制剂唑类。
Aromatic ethers of 1-aryl 2-(1H-azolyl)ethanol: study of antifungal activity
Aromatic ethers related to antifungal azole miconazole were synthesized and tested against various strains of Candida. We found that activity is related to the nature of the aromatic ring and the position of substituents on this ring. Activity is more strongly dependent on the substituent in the 2 position of the ethyl chain than on the aromatic group linked through the oxygen. Triazoles were always less potent than the corresponding imidazole analogues.
