  摘要：

  1,2-二氢吡啶并[3,4-b]吡嗪（1）是在小鼠中具有显着抗肿瘤活性的有丝分裂抑制剂。同样，活性咪唑并[4，5-b]吡啶3被显示导致有丝分裂时细胞的积累。通过用原甲酸乙酯环化4-（取代的氨基）-5,6-二氨基吡啶，合成了3的同类物。4，5-或5，6-二氨基吡啶与芳基醛的氧化环化分别产生了[4，5-c]和[4，5-b]咪唑并吡啶环系统。后者与6-（取代的氨基）-4,5-二氨基吡啶的反应得到咪唑并[4,5-c]吡啶环类似物。1。生物学研究表明，目标化合物的活性低于1和3。

  Cyclization of ethyl 5,6-diamino-4-hydrazinopyridin-2-ylcarbamate (10) with a mixture of CS2 and Et3N in dimethylacetamide gave mainly ethyl 1,4-diamino-2(3H)-thioxoimidazo[4,5-c]pyridin-6-ylcarbamate (15), whereas, in the absence of dimethylacetamide, a double cyclization gave mainly ethyl 5-amino-2(1H)-4-dithioxodiimidazo-[4,5-b:5,4-c]pyridin-7-ylcarb amate (16). Cyclization of the benzylidenehydrazino derivative (6) of 10 with either CS2-Et3N or (EtO)3CH-HCl gave 1-(benzylideneamino)imidazo[4,5-c]pyridines 11 and 7 as major products and 7-(benzylidenehydrazino)imidazo[4,5-b]pyridines 12 and 8 as minor products. Dethiolation of 11 to give 7 and of 12 to give 8 was effected with excess Raney nickel in refluxing ethanol. The benzylidene group of 11 was removed with hydrazine in ethanolic HCl to give 15. This key compound was condensed with benzaldehydes to give 1-benzylideneamino derivatives (20, 21) and alkylated with benzyl halides to give 2-benzylthio derivatives (24-26). In addition, cyclization of ethyl 5,6-diamino-4-(benzylidene-1-methylhydrazino)pyridin-2-ylcarbam ate (30) with (EtO)3CH provided a method for the synthesis of an imidazo[4,5-c]- and -[4,5-b]pyridines gave compounds that inhibited proliferation of growth and caused mitotic arrest against lymphoid leukemia L1210 at micromolar concentrations. However, the more active in vitro compounds (7, 8, 24-26) gave only borderline activity in mice against lymphocytic leukemia P388.

  antitumor activity in mice. Also, the active imidazo[4,5-b]pyridine 3 was shown to cause the accumulation of cells at mitosis. Routes were developed for the synthesis of congeners of 3 by cyclization of 4-(substituted amino)-5,6-diaminopyridines with ethyl orthoformate. Oxidative cyclization of either 4,5- or 5,6-diaminopyridines with aryl aldehydes produced the [4,5-c] and [4,5-b] imidazopyridine ring systems
