Pravastatin is a HMG-CoA reductase inhibitor of the cholesterol biosynthesis. It exhibits well-pronounced tissue selectivity. According to the invention, the producing strain Streptomyces roseochromogenes, registered in the NBIMCC under Nº 8072, is cultivated under submerged conditions in a nutrient broth containing in % w/w: glucose from 1 to 3; yeast extract from 0.5 to 1.0; sodium chloride from 0.1 to 1.0; calcium carbonate from 0.05 to 0.5; glycerol from 1 to 5, under aerobic conditions at temperature of 26 - 30°C, pressure 0.5 bar and pH 7.0 - 7.5. The advantage of the method is the high degree of transformation of ML-236B (compactin) to pravastatin.
普伐他汀是一种
胆固醇生物合成的
HMG-CoA 还原酶
抑制剂。它具有明显的组织选择性。根据本发明,生产菌株 Streptomyces roseochromogenes(已在 NBI
MCC 注册,编号为 8072)是在浸没条件下在营养肉汤中培养的,营养肉汤的重量百分比为:
葡萄糖 1 至 3;酵母
提取物 0.5 至 1.0;
氯化钠 0.1 至 1.0;
碳酸钙 0.05 至 0.5;
甘油 1 至 5。该方法的优点是可以将 M
L-236B(紧实素)高度转化为
普伐他汀。
