for the parallel solution-phase synthesis has been set up to obtain a series of thiouracils, in turn selectively S-benzylated under microwave irradiation to give new S-DABOs. Biological screening led to the identification of compounds with nanomolar activity toward both the highly purified recombinant human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT) enzyme (wild-type and mutants)
已经建立了用于平行溶液相合成的简单而有效的方法,以获得一系列硫尿嘧啶,然后在微波辐射下选择性地将S-苄基化,得到新的S-DABO。生物筛选导致鉴定出对高度纯化的重组人免疫缺陷病毒1型(HIV-1)逆转录酶(RT)酶(野生型和突变型)和野生型(wt)和突变型HIV具有纳摩尔活性的化合物-1株。特别是,发现20种是迄今为止报道的最有效的S-DABO(针对分离的wt酶的ID50 = 26 nM),对wt和多抗性病毒(IRLL98)HIV-1菌株均具有亚纳摩尔活性(EC50 <0.14 nM和EC50分别为0.22 nM)。
