Abstract
Four new 5-substituted camptothecins (4-7) have been synthesized and e valuated for DNA topoisomerase I inhibition. The results suggested tha t the pyridone moiety in the D ring of camptothecin plays a crucial ro le in determining its activity and that the 5 position of the C ring s hould be unsubstituted for retention of activity.
