A series of 10-position substituted nitrogenous heterocyclic aromatic 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
制备了一系列的SN-38的10位取代的含氮杂环芳族衍生物。这些化合物大多数具有比CPT低的细胞毒性。化合物13显示有效的细胞毒性相似CPT,和化合物17,18,和19显示出相似的细胞毒性活性以托泊替康。所有吡啶盐衍生物(7 – 16)显示出与CPT相当或更好的topo I抑制活性。与相应的吡啶盐CPT衍生物相比,这些化合物的7位乙基可增加对topo I的细胞毒性和抑制活性(7a – 13a),同时保持良好的水溶性。此结果与CPT的SAR一致。
