Synthesis of new functionally substituted 2-oxo(thioxo)nicotinic acid amides and nitriles by SNVin reaction
摘要:
New functionally substituted 2-oxo- and 2-thioxonicotinic acid amides and nitriles were synthesized by condensation of 3,3-bis(methylsulfanyl)acrylonitriles with CH acids according to the S(N)Vin pattern.
对基于结构的药物设计的深入研究可以为新型临床活性分子的开发提供重要线索。在本研究中,使用分子对接研究设计了二十六个新颖的吡唑并[1,5- a ]嘧啶类似物(6a - 6z)。设计的分子以高收率合成。使用IR,MS,1 H NMR和13 C NMR光谱进行合成分子的结构阐明。通过Alamar Blue测定法评价所有合成的化合物对H37Rv菌株的体外抗结核活性。大多数合成的化合物显示出有效的抗结核活性。在所有测试的化合物中6p,6g,6n和6h表现出有希望的抗结核活性。此外,对这些有效化合物进行了MDR-TB,XDR-TB和细胞毒性研究的评估。这些化合物均未显示出有效的细胞毒性。蛋白配体复合物的稳定性通过分子动力学模拟进一步评估了10 ns。所有这些结果表明,合成的化合物可能是进一步开发新的有效抗结核药的潜在线索。

A series of novelneonicotinoidanalogs containing an amidemoiety were synthesized, characterized, and subsequently evaluated for their insecticidalactivity. According to the preliminary bioassay, the compounds 6c, 6e, 6f, 6j, 6n, and 6r exhibited > 50% activity against Nilaparvata lugens at 100 mg/L. Amongst the active compounds, 6f and 6r revealed insecticidalactivities similar to that displayed

Abstract The synthesis of novel pyrido[2,1-b]benzothiazole and pyrido[2,1-b]benzoimidazole derivatives was achieved via the reaction of N-aryl-2-cyano-3,3-bis(methylthio)acrylamide with benzothiazoleylacetonitrile and benzoimidazoleylacetonitrile, respectively, while N-substituted 2-pyridylbenzothiazole derivatives were synthesized by reacting 2-(benzo[d]thiazol-2-yl)-3-(dimethylamino)acrylonitrile

Reaction of cyanoacetanilides with 3,3-bis(methylthio)-2-cyano-N-arylacrylamides proceeds to form isomeric N,1-diaryl-1,6-dihydropyridine-3-carboxamides. A single crystal consisting of 2-amino-4-methylthio-N-(2-methoxyphenyl)-6-oxo-1-phenyl-5-cyano-1,6-dihydropyridine-3-carboxamide and 2-amino-4-methylthio-1-(2-methoxyphenyl)-6-oxo-N-phenyl-5-cyano-1,6-dihydropyridine-3-carboxamide was studied by XRD.
