The present invention relates to effective drugs for mycosis caused by so called fungi such as fungi and yeast. The present invention is comprised of culturing a microorganism belonging to genus
Streptomyces
and having ability to produce K99-5278A substance, K99-5278B substance and K99-5278C substance in a medium, accumulating K99-5278A substance, K99-5278B substance and K99-5278C substance in the cultured medium and isolating K99-5278A substance, K99-5278B substance and K99-5278C substance from the cultured mass. The thus obtained substances can be expected as a novel antifungal agent.
本发明涉及治疗由所谓真菌(如真菌和酵母菌)引起的霉菌病的有效药物。本发明包括培养一种属于
链霉菌属
并能在
培养基中产生 K99-5278A 物质、K99-5278B 物质和 K99-5278C 物质,在
培养基中积累 K99-5278A 物质、K99-5278B 物质和 K99-5278C 物质,并从培养物中分离 K99-5278A 物质、K99-5278B 物质和 K99-5278C 物质。由此获得的物质有望成为一种新型抗真菌剂。
