摘要:
A microorganism having ability to produce FKI-0076 substance represented by the following formula [I] is cultured in a medium allowing for the accumulation of FKI-0076 substance in the culture liquid. The FKI-0076 substance from can then be isolated the cultured mass. Since the substance has the ability to enhance azole antifungal agents, it provides an action against various fungal infections such as deep-seated mycosis and other fungal infections in low concentration and within a short term. Consequently, the FKI-0076 is useful for reducing the frequency of appearance of resistant microorganisms. Further, usefulness for overcoming resistance is expected.

Roselipin derivatives which are represented by the following formula: [wherein R1 represents a hydrogen atom, mannose or acetylated mannose, R2 represents a hydrogen atom or a methyl group, and R3 represents a methyl group or a sugar alcohol], excluding a compound in which R1 is mannose, R2 is a hydrogen atom and R3 is arabinitol (roselipin 1A or 1B) and a compound in which R1 is acetylated mannose, R2 is a hydrogen atom and R3 is arabinitol (roselipin 2A or 2B), and which are useful for preventing and treating a disease of a human which is caused by accumulation of triacylglycerol can be obtained.
摘要:
A process for producing a substance KF-1040A represented by formula (I), and another substance KF-1040B represented by formula (II), which comprises culturing microorganisms capable of producing the substances KF-1040A and KF-1040B, thus accumulating these KF-1040A and/or KF-1040B in the liquid culture and harvesting the same from the culture. Because of the activities of inhibiting diacyloglycerol transferase and sphingomyelinase, the above substances are useful in preventing and treating arteriosclerosis, obesity, thrombus, inflammation and immune function-related diseases.
摘要:
A compound effective in prevention and treatment of arteriosclerosis with a mechanism different from that of statin drugs has the following formula or a pharmaceutically acceptable salt, solvate, or hydrate thereof: wherein R1 is an aliphatic, alicyclic, or aromatic acyloxy group, or a group of the formula —O—CH(R7)—R8 where R7 is a lower alkoxy group and R8 is an aryl group, and R2 is carboxyl, a lower alkoxycarbonyl group, or an arylmethylcarbamoyl group, or a —CH2-acyloxy group and R3 is an aliphatic, alicyclic or aromatic acyloxy group, provided that at least one of R4 and R3 is a group other than acetoxy, or R2 and R3 taken together form a group of the formula —O—CH(R5)—O— where R5 is an aryl group.
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.
摘要:
The present invention provides compounds which exhibit an inhibitory effect on undecaprenyl diphosphate synthase of microbes and thereby they are expected to be used clinically as pharmaceutical agents for infectious diseases caused by bacteria.The process comprises culturing a microbe belonging to Penicillium and having ability of producing an FKI-3368 substance in or on a nutrient medium to accumulate the FKI-3368 substance in the nutrient medium and collecting the FKI-3368 substance from the culture.

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 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.
