hydroxide powder and acetonitrile system. The structures of title compounds 2 and 3 were confirmed by elemental analysis, IR, 1H NMR, 13C NMR, 31P[1H] NMR,and mass spectral data. These symmetric [(O,O′-monoaryl)-thiophosphoryl)]-(20S)-camptothecin (2a–f) and asymmetric [(O-ethyl-O′-aryl)-thiophosphoryl)]-(20S)-camptothecin (3a–f) compounds were also tested for their in vitro antimicrobial activities against
摘要 通过 10-羟基喜树碱与各种对称 (O,O'-单芳基)-硫代磷酰氯和不对称 (O-乙基-O'-芳基)-硫代磷酰氯在钠溶液中的缩合反应,高效合成了一系列标题化合物 2 和 3。氢氧化物粉末和乙腈系统。标题化合物2和3的结构经元素分析、IR、1H NMR、13C NMR、31P[1H]NMR和质谱数据确证。这些对称 [(O,O'-单芳基)-硫代磷酰基)]-(20S)-喜树碱 (2a-f) 和不对称 [(O-乙基-O'-芳基)-硫代磷酰基)]-(20S)-喜树碱 ( 3a-f) 还测试了化合物对一些细菌菌株的体外抗菌活性,即金黄色葡萄球菌、B. Simplex、E. acetylicum、E. coli、P. aeruginosa、S. flexenari、S. aureus、S . 伤寒和一些真菌菌株黑曲霉,Aspergillus flavus(霉菌)、S. cerevisiae、C. albicans、T
