While chlorination of 2',3'-dideoxycytidine removed the anti-HIV activity, introduction of a chlorine at the C-5 position of 3'-fluoro-, 3'-azido- or 2',3'-didehydro-2',3'-dideoxycytidine led to reduced cytotoxicity with only slightly reduced anti-HIV activity. X-ray analysis showed compound 11 to have two molecules in the asymmetric unit with chi = -168.8 (3) degrees and -131.3 (3) degrees and P = 179
鉴于2',3'-dideoxy-3'-fluoro-5-chlorouridine(11)的选择性抗HIV活性,合成了8个2',3'-dideoxy-5-chloropyrimidines并评估了它们对MT-4细胞中1型人类免疫缺陷病毒(HIV-1)复制的抑制活性。注意到2,3-二脱氧核糖呋喃糖,3-叠氮基-2,3-二脱氧核糖呋喃糖和3-氟-2,3-二脱氧核糖呋喃糖的5-氯尿嘧啶衍生物的选择性显着改善,这主要是由于该化合物对宿主细胞。虽然氯化2',3'-二脱氧胞苷可消除抗HIV活性,但在3'-氟-,3'-叠氮基或2',3'-二氢-2'的C-5位置引入了氯,3'-二脱氧胞苷导致细胞毒性降低,而抗HIV活性仅略微降低。X射线分析表明化合物11在不对称单元中具有两个分子,分别为chi = -168.8(3)度和-131.3(3)度,P = 179(1)度和163(1)度。因此显示与3'-叠氮基-3'-脱氧胸苷(AZT)没有相似之处。
