From a methanol extract of Artemisia caruifolia, which showed a moderate inhibitory activity on HIV-1 protease in a preliminary screening, N1, N5, N10-tri-p-coumaroylspermidine and three dicaffeoylquinic acids were isolated. The former compound was found to appreciably inhibit HIV-1 protease. Of related amides which were chemically synthesized, N1, N5, N10, N14-tetra-p-coumaroylspermine and N1, N4, N7, N10, N13-penta-p-coumaroyltetraethylenepentamine inhibited HIV-1 protease more potently than N1, N5, N10-tri-p-coumaroylspermidine.
在初步筛选中,青蒿的甲醇提取物对 HIV-1 蛋白酶显示出中等程度的抑制活性,从这种提取物中分离出了 N1、N5、N10-三对香豆酰丝氨酸和三种二咖啡酰奎宁酸。发现前一种化合物对 HIV-1 蛋白酶有明显的抑制作用。在化学合成的相关酰胺中,N1、N5、N10、N14-四对香豆酰过胺和 N1、N4、N7、N10、N13-五对香豆酰四乙烯五胺对 HIV-1 蛋白酶的抑制作用强于 N1、N5、N10-三对香豆酰过胺。
