The biohydroxylation of stemodin and stemodinone by Beauveria bassiana ATCC 7159 gave exclusively 2alpha,13,18-trihydroxystemodane and 13,18-dihydroxystemodan-2-one respectively. Stemarin was converted to the novel 1beta,13,19-trihydroxystemarane and 13-hydroxystemarane-19-carboxylic acid. The synthesis and biotransformation of various derivatives of stemodin have also been studied.
白僵菌 ATCC 7159 对大黄素和大黄酮的生物羟基化分别产生了 2alpha,13,18-trihydroxystemodane 和 13,18-dihydroxystemodan-2-one。Stemarin 被转换为新型 1beta,13,19-trihydroxystemarane 和 13-hydroxystemarane-19-carb 酸。还研究了大黄素的各种衍生物的合成和生物转化。
