virus type-1 (HIV-1). Reaction of urea with a beta-ketoester furnished 6,7,8,9-tetrahydro-9-phenyl-1H-cyclohepta[d]pyrimidine-2,4-(3H,5H)-dione (6a) and 6,7,8,9-tetrahydro-9-p-tolyl-1H-cyclohepta[d]pyrimidine-2,4-(3H,5H)-dione (6b) which were then alkylated at the N-1 position with chloromethyl ether, allyl bromide and benzyl bromide to afford the target compounds 7a-b, 8a-b, 9 and 10, respectively. The
已经合成了新化合物,可以将其视为MKC-442的构象受限类似物,并已作为人免疫缺陷病毒1型(HIV-1)逆转录酶的抑制剂进行了测试。尿素与β-酮酸酯的反应提供了6,7,8,9-四氢-9-苯基-1H-环庚[d]嘧啶-2,4-(3H,5H)-二酮(6a)和6,7, 8,9-四氢-9-对甲苯基-1H-环庚[d]嘧啶-2,4-(3H,5H)-二酮(6b),然后在N-1位用氯甲基醚,烯丙基溴烷基化和苄基溴,分别得到目标化合物7a-b,8a-b,9和10。七元退火的化合物具有相对刚性的结构,可以锁定芳环的方向。曾尝试在吡啶环和9-苯基环的N-1处进行化学修饰,目的在于提高抗逆转录病毒活性。特别地,在N-1侧链的末端用苯基部分取代脂族基团可以增强活性。最具活性的化合物在低微摩尔范围内显示活性,IC50值可与奈韦拉平相当。生物活性结果与对接结果一致。
