Abstract

During a large laboratory-scale purification of FK228 from the fermentation broth of MSMB43, a small amount of thiosulfinated FK228 (TS-FK228) was unexpectedly purified only after the broth was mixed with silica gel. Evidence supports the postulations that TS-FK228 was derived from FK228 through spontaneous chemical reaction with silica gel, and TS-FK228 existed as two isomers and . TS-FK228 demonstrated similar inhibitory activity and profile against human class I histone deacetylases but exhibited a much higher antiproliferative activity against representative human cancer cell lines when compared to FK228.

摘要

在大规模实验室规模从MSMB43发酵液中纯化FK228的过程中,仅在发酵液与硅胶混合后意外地纯化出少量硫代硫化FK228(TS-FK228)。有证据支持以下推测:TS-FK228是FK228与硅胶自发化学反应衍生而来,且TS-FK228以两种异构体形式存在。TS-FK228对人I类组蛋白去乙酰化酶表现出相似的抑制活性和作用模式,但与FK228相比,对代表性人类癌细胞系表现出更高的抗增殖活性。
