1.  Anti-AIDS agents 79. Design, synthesis, molecular modeling and structure-activity relationships of novel dicamphanoyl-2′,2′-dimethyldihydropyranochromone (DCP) analogs as potent anti-HIV agents 
Bioorganic & medicinal chemistry  2010;18(18):6678-6689.
In a continued study, 23 3′R,4′R-di-O-(−)-camphanoyl-2′,2′-dimethyldihydropyrano[2,3-f]chromone (DCP) derivatives (5–27) were synthesized, and screened for anti-HIV activity against both a non-drug-resistant NL4-3 strain and multiple reverse transcriptase (RT) inhibitor-resistant (RTMDR-1) strain, using 2-EDCP (4) and 2-MDCP (35) as controls. New DCP analogs 5, 9, 14, and 22 exhibited potent anti-HIV activity against HIVNL4-3 with EC50 and therapeutic index (TI) values ranging from 0.036 μM to 0.14 μM and from 110 to 420, respectively. Compounds 5 and 9 also exhibited good activity against RTMDR-1 (EC50 0.049 and 0.054 μM; TI 310 and 200, respectively), and were two-fold more potent than the leads 4 and 35 (EC50 0.11 and 0.19 μM; TI 60 and 58, respectively). Evaluation of water solubility showed that 5 and 22 were 5–10 times more water soluble than 4. Quantitative structure-activity relationship (QSAR) modeling results were first performed on this compound type, and the models should aid in design of future anti-HIV DCP analogs and potential clinical drug candidates.
