Abstract

Novel 2-imino-6-(aryldiazenyl)-2H-chromene-3-carboxamides 6a–e, 2-amino-4H-cyclopenta or benzo[b]thiophene-3-carboxamides 10a,b, 2,7-diaminopyrazolo[1,5-a]pyrimidine-6-carboxamides 13a–e, pyrimidine-5-carboxamides 14, 15 and 3-amino-1H-pyrazole-4-carboxamide 16 were synthesized from the reaction of 2-cyano-N-(1,3-dihydroxy-2-(hydroxyl-methyl) propan-2-yl) acetamide 2 with 4-arylazosalicylaldehydes 5a-e, cyclopentanone and/or cyclohexanone, guanidine derivatives and hydrazine hydrate, respectively. Some new compounds were evaluated for antibacterial activity in vitro, and exhibited good efficacy compared to gentamicin. Compound 4c showed greater activity against gram negative bacteria (Klebsiella pneumonia and Pseudomonas aeruginosa) than standard antibiotic. Compound 4c with two withdrawing groups also showed the higher activity (38.7 ± 0.6) against fungi (Candida albicans) than the Nystatin (20 ± 0.5). On the other hand, compounds 13a, 13c, and 13e have strong cytotoxic activity among the tested compounds in the three selected cancer cell lines (HePG2, MCF7 and Hela). Physicochemical characterization by Swiss ADME predication was also performed for some synthesized compounds exhibiting better biological and antimicrobial properties.

使用生物缓冲剂三(羟甲基)氨基甲烷(THAM)高效合成、表征和硅学研究新型铬、噻吩、吡唑并[1,5-a]嘧啶和嘧啶,将其作为潜在的抗菌剂和抗癌剂
新型 2-亚氨基-6-(芳基二氮)-2H-苯并吡喃-3-甲酰胺 6a-e、2-氨基-4H-环戊二烯或苯并[b]噻吩-3-甲酰胺 10a,b、2,7-二氨基吡唑并[1,5-a]嘧啶-6-甲酰胺 13a-e、嘧啶-5-甲酰胺 14、15 和 3-氨基-1H-吡唑-4-甲酰胺 16 分别由 2-氰基-N-(1,3-二羟基-2-(羟基甲基)丙-2-基)乙酰胺 2 与 4-芳基水杨醛 5a-e、环戊酮和/或环己酮、胍衍生物和水合肼反应合成。对一些新化合物进行了体外抗菌活性评估,结果表明,与庆大霉素相比,这些化合物具有良好的疗效。与标准抗生素相比,化合物 4c 对革兰氏阴性菌(肺炎克雷伯氏菌和铜绿假单胞菌)的活性更高。化合物 4c 的两个提取基团对真菌(白色念珠菌)的活性(38.7 ± 0.6)也高于奈司他丁(20 ± 0.5)。另一方面,在所测试的化合物中,13a、13c 和 13e 对三种选定的癌细胞系(HePG2、MCF7 和 Hela)具有很强的细胞毒性活性。此外,还通过瑞士 ADME 预测法对一些合成化合物进行了理化表征,结果表明这些化合物具有更好的生物和抗菌特性。
