CONSTITUTION:The objective medicine contains a compound of the formula [R1 and R2 are H, 1-6C alkyl or R3CO (R3 is H or 1-6C alkyl] as an active ingredient. Radisicol which is a compound of the formula wherein R1 and R2 are simultaneously H is obtained by subjecting, e.g. Penicillium luteo-aurantiumu Smith (IFO-8176) to stationary culture at 27 deg.C for 21 day. The compound other than radisicol expressed by the formula is preferably obtained by alkylating a hydroxyl group of radisicol with an alkyl halide or esterifying the hydroxyl group using a carboxylic acid, its acid chloride or acid anhydride. The compound of the formula is preferably administered in several portions in an amount of 50-300mg/adult daily in the case of oral administration.
