摘要
目的获得安丝菌素及安丝菌素P-0纯品。方法珍贵束丝放线菌ATCC 31565经固体发酵培养,培养物乙酸乙酯萃取、硅胶柱层析后得到安丝菌素P-2、P-3和P-4混合物。安丝菌素混合物经化学法脱去C-3酰基侧链,采用制备型HPLC获得安丝菌素P-0纯品。结果每升固体发酵培养基可获得安丝菌素P-2、P-3和P-4混合物(98±2)mg(纯度85%)。50mg该安丝菌素样品可获得安丝菌素P-0纯品约31mg(纯度大于99%),产率约82%。结论将安丝菌素固体发酵培养与提取、去酰基化和HPLC纯化相结合,建立了一套安丝菌素P-0纯品的实验室制备工艺。
Objective To produce ansamitocins （a mixture of P-2, P-3 and P-4） by Actinosynnema pretiosum ATCC 31565 and obtain ansamitocin P-0 by chemical de-acylation of ansamitocins. Methods Solid-state fermentation of A. pretiosum ATCC 31565 was carried out for ansamitocins production. Ethyl acetate extraction andsilica gel column fractionation were conducted to obtain the mixture preparation of ansamitocins P-2, P-3 and P-4. The mixture was then used to generate ansamitocin P-0 by chemical de-acylation. Results Mixture of ansamitocins （purity ≥85% by HPLC） was obtained at a yield of （98±2）mg/L. The yield of ansamitocin P-0 （purity ≥ 99% by HPLC） was about 82% from ansamitocins. Conclusion A simple and efficient procedure for laboratory production of ansamitocins and ansamitocin P-0 was established.
