A series of 10-position substituted nitrogenous heterocyclicaromatic group derivatives of SN-38 were prepared. Most of these compounds possessed lower cytotoxicities than CPT. Compound 13 revealed potent cytotoxicity similar to CPT, and compounds 17, 18, and 19 showed similar cytotoxic activity to topotecan. All of the pyridine salt derivatives (7–16) revealed comparable or superior topo I inhibitory
