摘要: 丝裂霉素及其类似物,广泛应用于各种肿瘤.为了获得优异的产率和环境友好性,采用一锅法工艺,以漆酶/脂肪酶为催化剂,催化2-甲基苯-1,4-二酚与正丁胺的多米诺反应制备丝裂霉素类似物2-丁胺-3-甲基-1,4-苯醌(c).采用响应面技术优化了反应条件:2-甲基苯-1,4-二酚与胺的物质的量比为1.16∶1、漆酶与脂肪酶的活性比为1.14∶2、反应温度为38.9 ℃,最佳产率达到87.17%.建立了产率模型,该模型考虑了2-甲基苯-1,4-二酚与胺的物质的量比、漆酶与脂肪酶活性比和反应温度对产率的影响,可以准确的预测产率(R2为0.994 1).漆酶/脂肪酶协同催化体系一锅法合成丝裂霉素类似物,显著提高了产率,可作为提高丝裂霉素类似物产率的绿色替代工艺.

Abstract: Mitomycins and its analogs have been widely used for treating various tumors. In order to obtain excellent yield and environmental friendliness, an efficient one-pot process for the synthesis of 2-(butylamino)-3-methyl-1, 4-benzoquinone (c), a mitomycin-like compound by the domino reaction of 2-methylbenzene-1, 4-diol and butylamine using laccase/lipase as co-catalysts, has been developed. In the work, the process proposed here was improved by optimizing the relevant factors using the response surface methodology. The optimum conditions were obtained as follows: molar ratio of 2-methylbenzene-1, 4-diol to amine was 1.16∶1, activity ratio of laccase to lipase was 1.14∶2 and reaction temperature was 38.9 ℃, in which the highest yield was 87.17%. The yield model was established, which considered the effects of the amount of 2-methylbenzene-1, 4-diol to amine, the activity ratio of laccase to lipase and the reaction temperature on the yield and could accurately predict the yield (R=0.994 1). The results obtained indicate that this process may be useful as a green alternative process forhigher yield production of mitomycin analogs.
