设计,合成新型呋喃附加苯并硫氮杂derivatives衍生物并作为有效的VRV-PL-8a和H + / K + ATPase抑制剂进行体外生物学评估
摘要:
从1-(呋喃-2-基)乙酮开始合成了一系列新的呋喃衍生的[1,4]苯并噻氮平类似物。1-(呋喃-2-基)乙酮通过与各种芳族醛反应而转化为查尔酮,然后在酸性条件下与2-氨基苯硫醇反应,以高收率获得标题化合物。合成的新化合物通过1 H NMR,13 C NMR,质谱研究和元素分析进行表征。对所有新化合物的体外VRV-PL-8a和H + / K + ATPase抑制剂特性进行了评估。初步研究表明,设计序列中的一些分子显示出有希望的VRV-PL-8a和H + / K +ATPase抑制剂的特性。此外,进行了刚体对接研究,以了解分子在靶蛋白上的可能对接位点和结合方式。这一发现提出了一系列有前途的先导分子,它们可以作为治疗炎症相关疾病的原型,从而减轻其他NSAID所显示的溃疡诱导的副作用。

Xanthineoxidase is a complex molybdoflavoprotein that catalyses the hydroxylation of xanthine to uric acid. Fifty three analogues of 1-acetyl-3,5-diaryl-4,5-dihydro(1H)pyrazoles were rationallydesigned and synthesized and evaluated for in vitro xanthineoxidase inhibitory activity for the first time. Some notions about structure activity relationships are presented. Six compounds 41, 42, 44, 46,
Chalcone is an aromatic ketone that forms the central core for a variety of important biological compounds, which are collectively known as chalcones. The cytotoxic potential of chalcones which consists of C-6-C-3-C-6 units gets enhanced by the incorporation of pyrazole ring as proved by our earlier studies. Thus in the present work, pyrazoles of chalcones with ring A substituted by furan, naphthalene and variety of substituted phenyl rings has been prepared and evaluated for in vitro cytotoxic activity against PC-3, OVCAR, IMR-32, HEP-2 human cancer cell lines.All the synthesized compounds were evaluated for in vitro cytotoxicity against PC-3, OVCAR, IMR-32, HEP-2 human cancer cell lines. Compound 68 was found to be the most potent showing broad spectrum of cytotoxicity against all the cell lines .
