Comparison of UV, IR, PMR and CD spectra of epicorazine B with those of epicorazine A, a previously isolated metabolite of Epicoccum nigrum, showed that they were isomers with the same epidithiodiketopiperazine skeleton. X-Ray determination of epicorazine B indicated that the difference is related to a cis-trans configuration.
将表型霉素B与表型霉素A（一种先前从黑附球菌中分离出的代谢产物）的紫外光谱、红外光谱、核磁共振氢谱和圆二色光谱进行比较，结果表明它们是具有相同环二硫代二酮哌嗪骨架的异构体。表型霉素B的X射线测定表明，差异与顺反构型有关。
