The reaction of 4-dimethylaminomethylene-6-methyl-4H-pyrano[4,3-b]quinoline-1,3-dione with a range of primary amines gave rise to a series of 2-substituted 6-methyl-1-oxo-1,2-dihydrobenzo[b][1,6]naphthyridine-4-carboxylic acids. The derived 4-N-[2-(dimethylamino)ethyl]carboxamides were tested for growth inhibitory properties against murine P388 leukemia, Lewis lung carcinoma (LLTC), and human Jurkat
4-二甲基氨基亚甲基-6-甲基-4H-吡喃并[4,3-b]喹啉-1,3-二酮与一系列伯胺的反应产生了一系列的2-取代的6-甲基-1-氧代-1,2-二氢苯并[b] [1,6]萘啶-4-羧酸。测试了衍生的4-N- [2-(二甲基氨基)乙基]羧酰胺对鼠P388白血病,路易斯肺癌(LLTC)和人Jurkat白血病细胞系的生长抑制特性。大多数化合物是有效的细胞毒素,有些化合物的IC(50)值小于10 nM。在体内针对小鼠的皮下结肠38肿瘤进行了体内测试,对其中的5种进行了测试,事实证明,在该难治性模型中,单剂量(3.9 mg / kg)可治愈2-甲基和2-(3,4-二甲氧基苯基)衍生物。
