Abstract
In order to search for new anti-tumor and anti-viral agents, a series of α-aminophosphonate conjugates of 3-O-β-acetyl ursolic acid were prepared. Their biological activities as cytotoxic and anti-HIV agents were evaluated. The preliminary bioassays indicate that synthesized compounds 7a–j have anti-HIV activity (targeting HIV-1 gp120 and CD4) and no cytotoxicity on HT-29 cells (human colon adenocarcinoma cell line).
