Alkyl derivatives of the thiazolo[4,5-d]pyrimidine congeners of guanine and uracil were prepared and assessed for in vitro activity against human cytomegalovirus (HCMV). The finding that the 3-pentyl 1b and 3-hexyl 1c derivatives of 5-aminothiazolo[4,5-d]pyrimidine-2,7(3H,6H)-dione (1e) had potent in vitro anti-HCMV activity prompted a broader study of alkyl derivatives in this ring system. A series
制备鸟嘌呤和尿嘧啶的噻唑并[4,5- d ]嘧啶同类物的烷基衍生物,并评估其对人巨细胞病毒(HCMV)的体外活性。5-氨基噻唑并[4,5- d ]嘧啶-2,7(3 H,6 H)-二酮(1e)的3-戊基1b和3-己基1c衍生物具有很强的体外抗HCMV活性的发现促使对该环系统中的烷基衍生物进行更广泛的研究。1e的一系列3-烷基衍生物,即。通过将1e的钠盐直接烷基化制备1f-w 以及随后的修改2a-d。为了与1c进行比较,制备并研究了5-氨基-2-己基氨基噻唑并[4,5- d ]嘧啶-7(6H)-一(4)。发现1e的3-(2-链烯基)衍生物是具有更强活性的抗病毒药,具有5-氨基-3-(2-戊烯-1-基)噻唑并[4,5- d ]嘧啶-的Z异构体。2,7(3 H,6 H)-二酮(1f)具有更好的治疗指数。2-氨基噻唑并[4,5 - d ]嘧啶-5,7(4 H,6 H)-二酮6a和6b的类似4-(2-
