title: Caffeoylglycolic and caffeoylamino acid derivatives, halfmers of L-chicoric acid, as new HIV-1 integrase inhibitors.
abstract: Human immunodeficiency virus (HIV) integrase (IN) catalyzes the integration of HIV DNA copy into the host cell DNA. L-Chicoric acid (1) has been found to be one of the most potent HIV-1 integrase inhibitor. Caffeoylglycolic and caffeoylamino acid derivatives' halfmeric structures of L-chicoric acid 2 were synthesized for the purpose of simplifying the structure of L-chicoric acid. Among synthesized, compounds 2c and 3f showed HIV-1 IN inhibitory activities with IC(50) values of 10.5 and 12.0 microM, respectively, comparable to that of parent compound L-chicoric acid (IC(50)=15.7 microM).
