Definitions
- Parasitic diseases have been reduced due to improvements in the living environment and advances in anthelmintic drugs, but in recent years imported parasitic diseases, zoonotic parasitic diseases, opportunistic parasitic diseases, and parasitic products derived from fresh foods Insect worms and the like have become noticeable and have become a major problem again. Parasitic diseases also bring a great economic burden to livestock and agriculture. Among helminth infections among parasites, many compounds are currently being used, such as ivenucutin, mebendazole, and braziquantel. Problems to be solved by the invention
- NADH-fumarate reductase in the electron transport system, which is one of the promising targets of antihelminthic agents, and studied the inhibitor of NADH-fumarate reductase on microorganisms.
- the search in the culture was continued.
- Aspergillus A spergi 11 us
- the compound FT-0554 produced by Aspergi 1.1 usniger has NADH-fumarate reductase inhibitory activity, and has already filed an international application (International Publication No. W099 / 24439).
- the present invention relates to a NADH-fumarate reductase inhibitor comprising a substance FT-0 554 A as an active ingredient. Further, the present invention relates to an antihelminthic agent containing FT-0 554 A substance as an active ingredient.
- Proton nuclear magnetic resonance spectrum The chemical shift (p pm) of the formula [I] of the FT-0 554 A substance in heavy acetone is as follows. Where s is a singlet, d is a doublet, t is a triplet, q is a quadruple, m is a multiplet, br is a wide line, H is the number of protons, and J is a spin coupling constant (Hz). Is shown.
- FT-0554 A substance has the following formula [I]
- Aspergillus niger FT-0554 (FERM BP-644 3), a microorganism capable of producing FT-0554 substance belonging to the filamentous fungus disclosed in detail in International Publication No. WO 99/24439 After culturing, the FT-0554 substance is accumulated in the culture, and the FT-0554 substance represented by the following formula [ ⁇ ] is collected from the culture.
- the FT-0554A substance of the present invention can be produced by treating the thus obtained FT-0554 substance under Alkali conditions.
- FT-0554 substance is dissolved in an organic solvent, for example, alcohols such as methanol and ethanol, ethers such as dimethyl ether, dimethyl sulfoxide, and a common organic solvent such as chloroform.
- organic solvent for example, alcohols such as methanol and ethanol, ethers such as dimethyl ether, dimethyl sulfoxide, and a common organic solvent such as chloroform.
- basic compounds such as sodium carbonate, hydrogen carbonate, sodium bicarbonate, sodium bicarbonate, sodium methoxide, sodium hydride, sodium hydroxide, potassium hydroxide, and ammonia. A substance is produced.
- Purification from the reaction product can be carried out by the methods commonly used for the purification of fat-soluble organic compounds, for example, extraction with water-immiscible organic solvents such as black form and ethyl acetate, various types of chromatography, for example, adsorption chromatography, Gel filtration chromatography, scraping from thin-layer chromatography, centrifugal countercurrent distribution chromatography, high-performance liquid chromatography, and precipitation from poorly soluble solvents can be performed by selecting, combining, or repeating as appropriate.
- Pure FT- 0 5 5 4 A substance can be obtained.
- -The NADH-fumarate reductase inhibitory activity of the FT-0 554 A substance of the present invention obtained as described above is as follows. .
- the present invention can provide a novel FT-0554 A substance and a method for producing an FT-0554A substance from an FT-0554 substance.
- the proposed FT-0 554 A substance is expected to be a useful and satisfactory drug against parasitic infections.
