oxamides are involved in nucleic acid metabolism, and possess slight antiblastic activity against leukemia strain L1210. This provided a stimulus for a search for new imidazoles with potential antitumor activity [i-4]. The imidazole nucleus was used to introduce a variety of alkylating groups, including the bischloroethylamino group [5, 6]. These investigations resulted in the introduction of drugs
4,5-
氨基
咪唑甲酰胺参与核酸代谢,对白血病菌株L1210具有轻微的抗母细胞活性,1960年代就已确立。这为寻找具有潜在抗肿瘤活性的新型
咪唑提供了动力 [i-4]。
咪唑核用于引入多种烷基化基团,包括双
氯乙基
氨基 [5, 6]。这些研究导致将药物引入肿瘤学实践 [7, 8]。
