MASS SPECTROMETRY OF 1,3- AND 1,5-DICAFFEOYLQUINIC ACIDS

Popis výsledku v původním jazyce

The polyphenolic compound 1, also known as cynarin, is of interest biomedically because of its hypocholesterolemic, hepatoprotective and antioxidant activity.1 The dicaffeoylquinic acids (DCQAs), in general, show a number of pharmacological actions, withthe most important being anti-HIV activity. The DCQAs have recently been recognized as an important class of HIV-integrase inhibitors and, thus, prevent insertion of viral DNA into the host genome, and essential step in the replication of the virus. TheDCQAs strongly and irreversibly inhibit HIV-1 integration in biochemical assays and block viral replication at non-toxic concentrations. Earlier studies2 showed that the peracetate derivatives of 3 and 4 displayed greater anti-HIV activity than the freecompounds and that the activity of peracetyl-3 approaches that of AZT. Thus, there is considerable biomedical interest in the DCQAs and selected derivatives of the DCQAs. Obtaining quantities of pure 1 has been difficult. Extraction from
