Water-soluble phenolic compounds and their anti-HIV-1 activities from the leaves of Cyclocarya paliurus


Eight phenolic compounds including five glucuronides were isolated from the leaves of Cyclocarya paliurus (Batal.) Ijinskaja, which is used as a source of tea. Their structures were characterized by spectroscopic methods. The results of biological assay showed that compounds 1 and 5 had good activities against HIV-1 induced cytopathic effects in C8166 lymphocyte at non-cytotoxic concentrations, with EC50 values of 31.74 and 10.76 μM, and therapeutic index (TI) values of >13.02 and 25.46, respectively. Relationship between molecular structures and their bioactivities was discussed.
