摘要
目的:分离链霉菌SIPI-101菌株生物合成抗肿瘤活性的化合物。方法:优化发酵条件,进行大规模发酵;发酵液经离心,菌丝体在碱性条件下经过甲醇提取、乙酸乙酯萃取、硅胶柱层析、结晶等步骤,分离获得活性化合物SIPI-101-1;并测定其质谱、紫外光谱、核磁共振图谱等数据,并研究其生物学活性。结果:通过理化性质和图谱数据的分析,确定化合物SIPI-101-1的化学结构;生物活性研究发现其具有抗肿瘤活性。结论:活性化合物SIPI-101-1属于吲哚咔唑类生物碱,与文献报道的staurosporine结构一致。
AIM： To isolate anti-tumor agents from microorganism SIPI-101. MEHTODS： The fermentation condition of strain SIPI-101 was improved and scaled up. The mycelia were obtained by centrifugation. Using methanol and acetic ether extraction, silica gel column chromatography and crystallization, compound SIPI-101-1 was isolated from the broths; the spectral data of SIPI-101-1 were determined and its biological activity was studied. RESULT： The structure of SIPI-101-1 was identified by analyses of its physico-chemical properties, MS, UV and NMR spectra and anti-tumor activity was determined. CONCLUSION： The compound SIPI-101-1 produced by strain SIPI-101-1 is identical with staurosporine with strong anti-tumor activity.
