摘要:
A microorganism belonging to Beauveria sp. and having ability to produce FKI-1366 substance A and/or FKI-1366 substance B and/or FKI-1366 substance C (Beauveria sp. FKI-1366 FERM BP-08459) is cultured in a medium, accumulating FKI-1366 substance A and/or FKI-1366 substance B and/or FKI-1366 substance C in the culture liquid and isolating FKI-1366 substance A and/or FKI-1366 substance B and/or FKI-1366 substance C from the cultured mass. Since the thus obtained FKI-1366 substance A and/or FKI-1366 substance B and/or FKI-1366 substance C or composition thereof have activity to enhance azole antifungal agent, the substance has an action against various fungal infections such as deep-seated mycosis and other fungal infections in the low concentration within short term. Consequently, the substance is useful for reducing frequency of appearance of resistant microorganisms and overcoming resistance, and is expected as a medicament.
摘要:
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.
摘要:
The present invention is a process for selective production of beauveriolide I substance or beauveriolide III substance, in which a beauveriolide producing microorganism strain FO-6979 or mutant thereof is cultured in a medium for fungi added with specific amino acid in order to produce beauveriolide I substance or beauveriolide III substance selectively with high yield; beauveriolide I substance or beauveriolide III substance is accumulated selectively in the cultured mass; and beauveriolide I substance or beauveriolide III substance is collected selectively with high yield from said cultured mass.
摘要:
The present invention comprising culturing a microorganism which belongs to genus Streptomyces and has ability to produce K99-5041-C1x substance and/or K99-5041-C2x substance in a medium, accumulating K99-5041-C1x substance and/or K99-5041-C2x substance in the culture fluid, and isolating K99-5041-C1x substance and/or K99-5041-C2x substance form the cultured mass. Since the obtained K99-5041-C1x substance and/or K99-5041-C2x substance exhibit inhibitory activity against lanosterol synthase, these substances are expected to apply clinically for preventive and therapeutic agents caused by accumulation of cholesterol in humans and antifungal agents.
摘要:
The present invention relates to novel substance having inhibitory action on cholesteryl ester transfer protein, WK-5344A substance and WK-5344B substance, and process for production thereof. A microorganism belonging to genus Streptomyces having ability to produce WK-5344A substance and WK-5344B substance is cultured in a medium, and the WK-5344A substance and the WK-5344B substance are accumulated in the medium, then the WK-5344A substance and the WK-5344B substance are isolated from the said medium. Since the present substance shows significant inhibitory action on cholesteryl ester transfer protein, the substance is effective for prevention and treatment of diseases caused by accumulation of cholesterol in human.
摘要:
An antibiotic AM-5344-A.sub.2 substance, and a process for the preparation of the antibiotic AM-5344-A.sub.2 substance are described. The antibiotic AM-5344-A.sub.2 substance is prepared by cultivating an AM-5344-A.sub.2 substance-producing strain belonging to the genus Streptomyces, for example, Streptomyces sp. Am-5344 in a nutrient medium, and recovering the Am-5344-A.sub.2 substance from the culture.

摘要:
The present invention is a compound having the general formula (I), (II), or (III) or a pharmacologically acceptable salt, solvate, or hydrate thereof, and a pharmaceutical composition containing such a compound, or its pharmacologically acceptable ester, or other pharmacologically acceptable derivative thereof as an active ingredient. The compound has an excellent ACAT 2-inhibiting activity by a mechanism different from that of a statin drug and is useful as a therapeutic or prophylactic agent for obesity, adiposis, hyperlipidemia, hypercholesterolemia, disorder of lipid metabolism, and arteriosclerosis, as well as obesity-derived hyperlipidemia, hypercholesterolemia, disorder of lipid metabolism, arteriosclerosis, and hypertension.
