A previous reaction leading to 2-substituted 6-methyl-1-oxo-1,2-dihydrobenzo[b][1,6]naphthyridine-4-carboxylic acids has been extended to encompass a broad range of 2-substituents. Derived carboxamides, particularly 4-N-[2-(dimethylamino)ethyl], were tested for growth inhibitory properties. Potent cytotoxicity against murine P388 leukemia and Lewis lung carcinoma (LLTC) was retained for compounds bearing
导致2-取代的6-甲基-1-氧代-1,2-二氢苯并[b] [1,6]萘啶-4-羧酸的先前反应已扩展到涵盖广泛的2-取代基。测试了衍生的羧酰胺,特别是4-N- [2-(二甲基氨基)乙基]的生长抑制性能。对于带有2-取代基范围非常广泛的化合物的IC50值<10 nM的化合物,保留了对小鼠P388白血病和路易斯肺癌(LLTC)的有效细胞毒性。在小鼠中对其中的五种新化合物进行了体内皮下结肠38肿瘤测试;单剂量(1.8 mg / kg)证明可治愈2-(4-氟苯基)衍生物,与以前报道的非常有效的2-甲基类似物相比,其功效进一步提高。
