    • PURPOSE: A microorganism, Penicillium griseofulvum, producing pyripyropene A and a method for producing cholesterol metabolism inhibitor are provided, wherein pyripyropene A inhibits the activity of cholesterol acyltransferase(ACAT) which adsorbs cholesterol into blood, and is thus used in decreasing the blood cholesterol concentration. CONSTITUTION: Penicillium griseofulvum F1959 separated from soil by Samson method produces pyripyropene A which inhibits the activity of cholesterol acyltransferase(ACAT) and its inhibition concentration IC50 is about 35 ng/ml which is calculated by the equation. The ACAT inhibitor pyripyropene A is produced by the steps of: incubating Penicillium griseofulvum F1959 in a spawn medium containing 0.5% of glucose, 0.2% of yeast extract, 0.5% of polypeptone, 0.1% of potassium phosphate and 0.05% of magnesium sulfate at 29 deg. C for 18 hours; and incubating the microorganism in a growth medium containing 2% of starch, 0.4% of soytone, 0.3% of pama media, 0.1% of potassium phosphate, 0.05% of magnesium sulfate, 0.3% of calcium carbonate and 0.2% of sodium chloride at 29 deg. C for 120 hours.
    • 目的:提供微生物青霉菌青霉菌,产生吡柔比星A和生产胆固醇代谢抑制剂的方法,其中吡哆灵A抑制胆固醇酰基转移酶(ACAT)的活性,胆固醇酰基转移酶(ACAT)将胆固醇吸附到血液中,因此用于降低血液胆固醇浓度 。 构成:通过Samson方法从土壤中分离的灰黄霉菌F1959产生抑制胆固醇酰基转移酶(ACAT)活性的白藜芦醇A,其抑制浓度IC50为约35ng / ml,其通过该方程式计算。 通过以下步骤制备ACAT抑制剂pyripyropene A:在含有0.5%葡萄糖,0.2%酵母提取物,0.5%多聚蛋白胨,0.1%磷酸钾和0.05%硫酸镁的产卵培养基中将灰黄青霉F1959温育于29℃ 度。 C 18小时; 并在29℃下将微生物培养在含有2%淀粉,0.4%大豆油,0.3%帕马培养基,0.1%磷酸钾,0.05%硫酸镁,0.3%碳酸钙和0.2%氯化钠的生长培养基中 度。 C 120小时。
