以氨基酸酯为原料,在微波辐射条件下合成了系列N-3位含酯基的噻唑烷-4-酮衍生物,经水解并酰胺缩合制备了N-3位酰胺键连接嘧啶胺的二芳基噻唑烷-4-酮衍生物.化合物通过人类免疫缺陷病毒(HIV)逆转酶(RT)试剂盒(比色法)评价了其酶抑制活性.活性结果表明,部分化合物如5bb,5bc,5cb和5cc能有效地抑制HIV逆转酶的活性,IC_(50)值分别为4.15,3.53,4.61和4.06μmol/L.构效关系表明N-3位2个碳的柔性侧链以及亲脂基如甲基的引入将有利于化合物的抗HIV逆转录酶活性.
A series of thiazolidin-4-one derivatives possessing ester were synthesized under microwave irradiation using amino acid ester as starting material. After ester hydrolysis reaction and amide condensation reaction, the aimed diaryl thiazolindin-4-one derivatives possessing amide linkage on N-3 position were obtained. The compounds were evaluated for their human immunodeficiency virus(HIV-1) reverse transcriptase(RT) inhibitory activities in vitro HIV-1 RT kit assay(colorimetric method). The results showed that some of the compounds, such as 5bb, 5bc, 5cb, and 5cc could effectively inhibit RT activity with the IC50 values of 4.15, 3.53, 4.61 and 4.06 μmol/L, respectively. Structure activity relationship analysis of these analogues suggested that the introduction of two carbons side chain on N-3 position and lipophilic group like methyl group should be favorable to their anti-HIV-RT activitives.
