Abstract (+)-Calanolide A ( 1) as a natural product was previously found as an inhibitor of HIV-1 reverse transcriptase. In our further investigation of its template, racemic 11-demethyl-12-oxo calanolide A ( 15), which had two fewer chiral carbon centers at the C-11 and C-12 positions than (+)-calanolide A, had a comparably inhibitory activity and better therapeutic index (EC 50 = 0.11 microM, TI = 818) against HIV-1 in vitro. A library based on its structural core was then designed and synthesized with introduction of nine diversity points in this article. The evaluations of anti-HIV-1 activity in vitro concluded their structure-activity relationships (SARs). A novel compound (10-bromomethyl-11-demethyl-12-oxo calanolide A, 123) was identified to have much higher inhibitory potency and ......
