  摘要：

  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.

  Ring analogues and derivatives of the 1,2-dihydropyrido[3,4-b]pyrazin-7-ylcarbamates (e.g., 29), antimitotic agents with antitumor activity, were prepared in the search for compounds with greater selectivity. Methods were developed for the conversion of substituted benzoic acids (1-4) to give benzopyrazines (12-16 and 21) and of substituted pyridin-2-carbamates (23, 38, and 41) to give 2-aminopyrido[3

  为了寻找具有更高选择性的化合物，制备了具有抗肿瘤活性的1,2-二氢吡啶并[3,4-b]吡嗪-7-基氨基甲酸酯的环类似物和衍生物（例如29）。开发了用于将取代的苯甲酸（1-4）转化为苯并吡嗪（12-16和21）以及将取代的吡啶-2-氨基甲酸酯（23、38和41）转化为2-氨基吡啶[3,4]的方法。 -b]吡嗪-7-基氨基甲酸酯（32和36）和吡啶并[3,4-e]-三嗪-7-基氨基甲酸酯（47和50）。体外评估表明，通过除去29的吡啶环氮，活性降低，得到14；通过增加29的吡嗪环的碱度，活性被破坏，得到32和47。
