thio)thymine (HEPT), in which the C-2, N-3, or C-4 position was modified were synthesized. These involve 2-thiothymine (11), 2-thiouracil (12), 4-thiothymine (17), 4-thiouracil (18), 5-methylcytosine (27), and cytosine (28) derivatives. Preparation of N-3-substituted derivatives (29 and 30) of HEPT was also carried out. Among these analogues, compound 11 exhibited excellent activity against HIV-1 HTLV-IIIB
一种新的抗HIV-1药物铅的类似物,即1-[((2-羟基乙氧基)甲基] -6-(苯硫基)胸腺嘧啶(HEPT),其中C-2,N-3或C-4位置被合成。这些涉及2-硫胸腺嘧啶(11),2-硫尿嘧啶(12),4-硫胸腺嘧啶(17),4-硫尿嘧啶(18),5-甲基胞嘧啶(27)和胞嘧啶(28)衍生物。还进行了HEPT的N-3-取代的衍生物(29和30)的制备。在这些类似物中,化合物11对HIV-1 HTLV-IIIB菌株表现出优异的活性,EC50值为0.98 microM,比HEPT强7倍。化合物11中5-甲基的去除导致活性的完全丧失。其他化合物未显示任何抗HIV-1活性。发现4-硫代衍生物17和18具有相当的细胞毒性。
