title: Synthesis and anti-HIV-1 activities of novel podophyllotoxin derivatives.
abstract: In order to explore the range of biological activities of the podophyllotoxin compound class, a novel series of derivatives of podophyllotoxin, which were conjugates containing stavudine and different structural podophyllotoxin analogues, were designed, synthesized, and evaluated for their anti-HIV-1 activities in vitro. Among these compounds, 19d and 19c showed the highest anti-HIV-1 activities with EC(50) values of 0.17 and 0.29 microM and TI values of 466.9 and 354.5, respectively.
