were evaluated for anti-HIV-1, antitubercular and antibacterial activities. Compound (3-azido-tetrahydro-5- (3,4-dihydro-5-methyl-2,4-dioxopyrimidin- 1 (2H)-yl) furan-2-yl)methyl 7- (4- (2-phenylacetoyloxy) -3,5- dimethylpiperazin-1-yl) -5- (2-phenylacetoyloxyamino) -1-cyclopropyl-6,8-difluoro-1,4-dihydro-4-oxoquinoline-3-carboxylate (5) was found to be the most potent anti-HIV-1 agent with EC50 of
通过修饰糖部分的5'-羟基(1-8)和胸苷核的5-甲基(9-12),制备了十二种齐多夫定衍生物,并进行了光谱表征。评估了这些化合物的抗HIV-1,抗结核和抗菌活性。化合物(3-叠氮基-四氢-5-(3,4-二氢-5-甲基-2,4-二氧嘧啶--1(2 H)-基)呋喃-2-基)甲基7-(4-(2- phenylacetoyloxy)-3,5-二甲基哌嗪-1-基)-5-(2- phenylacetoyloxyamino)-1-环丙基-6,8-二氟-1,4-二氢-4-氧喹啉-3-羧酸乙酯(5)被发现是最有效的抗HIV-1药物,针对HIV-1 IIIB和CC 50的EC 50为0.0012μM相对于MT-4为34.05μM,选择性指数为28,375。化合物5以1.72μM的MIC抑制结核分枝杆菌,并以MIC小于1μM的抑制四种致病菌。
