PURPOSE:To obtain a new compound, having excellent antifungal action and useful as an antifungal agent. CONSTITUTION:The compound of the formula or its salt. Properties: white powder; molecular formula: C28H36O10; solubility: readily soluble in methanol, ethyl acetate, etc., and sparingly soluble in n-hexane and water; division of acidic, neutral and basic substances: weakly acidic substance and color reaction: positive to the potassium permanganate reaction and sulfuric acid reaction. A microorganism capable of producing the compound [e.g. Penicillium sp. F31405 strain (FERM P-132121) which is a new microorganism] is preferably cultured according to a shaking culture method or a submerged spinner culture method under aeration and the compound is then obtained from the resultant culture filtrate. Furthermore, the culturing is preferably carried out at 25-30 deg.C and pH4-8 for 120-216hr. |
