Potential antimitotic agents. Synthesis of some ethyl benzopyrazin-7-ylcarbamates, ethyl pyrido[3,4-b]pyrazin-7-ylcarbamates, and ethyl pyrido[3,4-e]-as-triazin-7-ylcarbamates

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。
