| Abstract: | Objective To isolate and identify FIM-R85, a metabolite from the broth of sirolimus producing strain Streptomyces hygroscopicus FC904. Methods FIM-R85 was separated by silica gel chromatography and preparative liquid chromatography. Its chemical structure was determined by physicochemical properties and spectral analysis including NMR, UV, IR as well as HRMS. Results The HPLC purity of FIM-R85 was 98.7% and it was an analogue of sirolimus, identical with 29-O-desmethylrapamycin. Conclusion 29-O-desmethylrapamycin was one of the metabolites of sirolimus producing strain Streptomyces hygroscopicus |
