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。
Triethylamin-mediated addition of 2-aminoethanethiol hydrochloride to chalcones: Synthesis of 3-(2-aminoethylthio)-1-(aryl)-3-(thiophen-2-yl) propan-1-ones and 5,7-diaryl-2,3,6, 7-tetrahydro-1,4-thiazepines

addition, bearing a 2-thienyl group at the 3-position, gave the only addition adduct at room temperature in 3 h, whereas the chalcones bearing the 2-furyl group at the 1-position gave an addition-cyclization product (1, 4-thiazepine) in the same conditions. The effect of the groups to the reaction was investigated by changing the 1- and 3-position groups. The chalcones bearing the 2-thienyl group at the 1-position

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,
Chalcones were found to undergo sulfurative dimerization with elementalsulfur to tetrasubstituted 1,3-dithioles. The reaction was found to proceed at room temperature in the presence of a nitrogen-base catalyst in DMSO.
Pyrazolines, the well‐known five‐membered nitrogen‐containing heterocyclic compounds, have received considerable interests in the fields of medicinal and agricultural chemistry because of their broad spectrum of biologicalactivities. To discover more potent antifungal compounds, a series of structurally related 1,3,5‐trisubstituted‐2‐pyrazoline derivatives have been synthesized by introducing furan

heterocyclic derivatives comprising oxygen atom is considered as a valuable combination of therapeutic agents in curative chemistry. In particular, isoxazole, a five-member heterocyclic ring, is detected along with some of the marketed drugs such as danazol, flucloxacillin, dicloxacillin, cloxacillin, and valdecoxib which are known as an anti-inflammatory drug. The incorporation of the isoxazole ring can
