To study the structure-activity relationship of alkyl 9-nitrocamptothecin esters. Two alkyl 9-nitrocamptothecin (9NC) esters 5g and 5h were prepared by esterification reactions of 9NC with valeric anhydride and heptanoic anhydride, respectively. Eight 9NC esters 5a-5h were tested for cytotoxicity against
