In our continued research on chlorogenic acid analogues and derivatives with improved bioactivity, we have synthesized some caffeoyl 5,6-anhydroquinic acid derivatives. The 1,7 acetonides of chlorogenic acid ( 15), and of the mono-caffeoyl 5,6-anhydroquinic acids (7-8) showed appreciable anti-HIV activity. The 3,4-dicaffeoyl 5,6-anhydroquinic acid ( 12) exhibited an anti-HIV activity twice as that of 3,5-dicaffeoylquinic acid ( 22). The caffeoyl 5,6-anhydroquinic acid derivatives displayed potent anti-oxidant activities. The mono-caffeoyl 5,6-anhydroquinic acids (10-11) were more than twice stronger than chlorogenic acid ( 21) on SOD-like activity. (C) 2009 Elsevier Ltd. All rights reserved.
