The 1,1,3-trioxo-2H,4H-thieno[3,4-e][1,2,4]thiadiazines (TTDs) represent a recently discovered chemical class of non-nucleoside reverse transcriptase inhibitors that selectively block human immunodeficiency virus type 1 replication. In a search for a better understanding of their mode of binding and with the aim of obtaining novel lead compounds, a second series of TTD derivatives was synthesized and
1,1,3-trioxo-2H,4H-thinono [3,4-e] [1,2,4] thiadiazines(TTDs)代表了最近发现的非核苷类逆转录酶抑制剂的化学类别,可选择性地阻断人类免疫缺陷病毒1型复制。为了更好地了解它们的结合方式,并为了获得新的先导化合物,合成了第二系列的TTD衍生物并评估了其抗病毒活性。新化合物的设计基于在原始原型20a(QM 96521)中进行的各种化学修饰。N-2苄基间位的卤素取代导致抗病毒活性提高了1个数量级。在N-4位带有的化合物是氰甲基,炔丙基,发现苯甲基或苄基取代基是该系列中最有效的。将与1,2,4-噻二嗪部分稠合的thieno [3,4-e]环修饰为其他杂环系统会降低其效力。这项研究获得的结果为更有效的TTD设计提供了新的指示。
