Using an HIV-1 Reverse Transcriptase (RT)-associated RNase H inhibition assay as lead, bioguided fractionation of the dichloromethane extract of the Ocimum sanctum leaves led to the isolation of five triterpenes (1-5) along with three 3-methoxy-4-hydroxy phenyl derivatives (6-8). The structure of this isolates were determined by 1D and 2D NMR experiments as well as ESI-MS. Tetradecyl ferulate (8) showed
使用HIV-1逆转录酶(RT)相关的RNase H抑制试验作为先导,乌头叶的二氯甲烷提取物的生物引导分级分离导致分离出5个三萜(1-5)和3个3-甲氧基-4 -羟基苯基衍生物(6-8)。该分离物的结构通过1D和2D NMR实验以及ESI-MS确定。阿魏十四酸(8)显示出有趣的RNase H IC50值为12.4μM,并且由于该次生代谢产物的合成可及性,因此进行了结构-活性关系研究。合成了一系列阿魏酸和咖啡酸的酯和酰胺,其中最活跃的是N-油基咖啡酰胺,对RT相关功能,核糖核酸酶H和DNA聚合酶均显示出强大的抑制活性。
