The λ-Radiolysis reactions of mitomycin C (1) and its derivatives were studied in the hope of developing a radiation-induced drug (RID). The λ-radiolysis reactions were carried out in aqueous solutions under the condition where hydrated electron (e−aq) was generated as a principal reactive species. The competitive λ-radiolysis studies revealed that the rate constants for the reactions of 1 with e−aq
研究了丝裂霉素C(1)及其衍生物的λ辐射分解反应,以期开发辐射诱导药物(RID)。在产生水合电子(e - aq)作为主要反应物种的条件下,在水溶液中进行λ辐射分解反应。竞争性λ辐射研究表明,室温下1与e - aq反应的速率常数为3.6×10 10 dm 3 mol -1 s -1。在丝裂霉素C衍生物中,5 H -6-烷氧基亚氨基衍生物11和12和化合物13,其中的环A 1具有4-羟基-6-肟基结构裂解,得到1。讨论了这些λ辐射分解反应的机械方面。
