6-Arylthio and 6-arylselenoacyclonucleosides was synthesized and tested for the ability to inhibit replication of HIV-1. Lithiation of acyclonucleosides with LDA followed by reaction with the electrophiles phenyl disulfide, diphenyl diselenide, 2,2′-dipyrdyl disulfide or 2,2′-dipyridyl diselenide afforded 6-(arylthio or arylseleno)acyclonucleosides 5a-c, 6, 7, 9, 15a-c, 17a-c. Compounds 19a-c and 20a-c
合成6-芳硫基和6-芳基硒基环杂核苷,并测试其抑制HIV-1复制的能力。将无环核苷酸与LDA锂化,然后与亲电试剂苯基二硫化物,二苯基二硒化物,2,2'-二吡啶基二硫化物或2,2'-二吡啶基二硒化物反应,得到6-(芳硫基或芳基硒代)无环核苷5a-c, 6、7、9 ,15a-c,17a-c。化合物19a-c和20a-c通过相应的TBDMS衍生物的脱保护得到。在反应期间也形成了脱水产物16a和18a-c。5-乙基-6-(α-吡啶硫基或α-吡啶硒基)双取代的无环尿嘧啶6和7与AZT,DDC,DDI或D4T相比,MT-2和CEM-IW细胞系对HIV-1的活性更高。CEM-IW细胞中针对HIV-1的EC 50为6,在纳摩尔范围内,治疗指数为1100。
