Description
The present invention be 030515 the applying date, application number is that 03116952.X, denomination of invention are the dividing an application of patent of invention of ' coumarin kind compound, synthetic method and application '.
Technical field
The present invention relates to of the application of a kind of coumarin kind compound as the preparation antifungal drug.This compounds has tangible antifungic action, is used for the treatment of paronychia, diseases such as tinea unguium.
Background technology
Coumarin belongs to the lactone of neighbour-hydroxyl cinnamic acid, and it extensively is present in plant such as Umbelliferae, pulse family, Rutaceae, Compositae, Saxifragaceae, thymelaeceae and the microbial metabolic products, but exists hardly in Animal World.The content of coumarin each several part in plant from many to little order
IiFor: fruit>root hair>branch>leaf.By 1980, nearly more than 800 of the coumarin compounds of having found.
Furocoumarin (furanocoumarin) has been used for a long time in conventional medicament, the mythical book of India " Athara Veda " has just been described with the poultice treatment leukoderma that extract in the Psoralea corylifolia tree, and the ancient Egyptian once controlled vitiligo with Ammi majus.First furocoumarin and 5-MOP (5-methoxypsoralen) 18 is Kalbrunner (Scott, B.R. in 1838; Pathak, M.A.; Mohn, G.R.Mutat.Res, 1976,39,29.) from oleum bergamottae, separate and to obtain.
Coumarin kind compound has wide biological activity, for example: anticoagulation (anticoagulant), zoohormone (estrogenic), anti-skin sensitivity activity (dermal photosensitizing activity), antibiotic (antimicrobial), cooling (hypothermal), vasodilation (vasodilator), molluscacide (molluscacidal), anthelmintic (anthelmintic),. tranquilizer and hypnotic (sedative and hypnotic) analgesic and cooling agent (analgesic and hypothermal activity) ((a) .Soine, T.O.J.Pharm.Sci, 1964,53,231. (b) .Edelson, R.L.Sci.Am., 1988, August, 68. (c) .Dini, A.; Ramundo, E.; Satumino, P.; Stagno, d ' Alcontres, I.Boll.Soc.Ital.Biol.Sper., 1992.Univ.Lodz.).In fact, coumarin kind compound has wide biological activity like this, so that has the people to be referred to as " a many-side people pharmaceutically " (Pharmacological promiscuity) (Hoult, J.R.; Paya, M.Gen.Pharmacol., 1996,27,713.).More significant physiologic effect has: the acute liver toxicity of aflatoxin (aflatoxin) and carcinogenecity (acute hepatotoxicity and carcinogenicity), anticoagulant property (Rocha, the L. of two tonquinols (dicoumarol); Marston, A.; Kaplan, M.; Stoeckli-Evans, H.; Thull, U.; Testa, B.; Hostettmann, K.Phytochem., 1994,36,1381.), novobiocin (novobiocin) and coumermycin A

Conclusion
4; 4 '-two Isofraxidin oral administrations have certain protective role to infecting Candida albicans 02-6 in the mice body; when dosage is 200mg/kg; its survival rate is 70%; 4,4 '-two Isofraxidin oral administrations are suitable substantially to endogenous protective effect and the fluconazol that infects Candida albicans in the mice body.
Embodiment 17 external susceptibility MIC tests
Method: each test bacterium is made bacteria suspension with normal saline, and to be diluted to turbidity be 2.0McF (the wet above bacteria suspension of bacteria concentration mg/ml, 100 times of reuse normal saline dilutions, 10 times of RPMI1640 dilutions, the sample doubling dilution, cultivate 72-96h in 96 well culture plates, slight vibration, the 490nm place carries out photoelectric colorimetry.
Test organisms: yeast, Candida albicans 01-5,01-1,02-6, Candida albicans CMCC, aspergillus niger, Cryptococcus histolyticus, red cryptococcus, trichophyton verrucum.
Result (MIC) adds following table:
Fluconazol (μ g/ml) | 4,4 '-two Isofraxidins (μ g/ml) | |
Yeast | 64 | >128 |
Candida albicans | >128 | 64 |
Candida albicans | >128 | >128 |
Candida albicans 01-5 | 128 | 64 |
Candida albicans CMCC | 64 | >128 |
Candida albicans 02-6 | 64 | 32 |
Candida albicans 01-1 | 128 | 64 |
Aspergillus niger | >128 | 128 |
Cryptococcus histolyticus | 16 | 64 |
Red cryptococcus | 16 | 16 |
Trichophyton verrucum | 128 | 128 |
Conclusion: 4,4 '-two Isofraxidins to the oidiomycetic antibacterial activity of white a little less than, MIC is 128,>128 μ g/ml, Aspergillus niger in the mycete, Cryptococcus histolyticus, red cryptococcus, trichophyton verrucum had antibacterial activity, the MIC value respectively is 128,64,16,128 μ g/ml, its antibacterial action is strong and weak basic identical with fluconazol.
Embodiment 18 Ames tests
According to the requirement of mutagenic test in " new drug (Western medicine) preclinical study guideline compilation (pharmacy, pharmacology, toxicology) ", set 5 dosage groups of 5,50,500,1000,5000 μ g/ wares, at no S
9In the experimental system, for 4,4 '-two Isofraxidins detect.The result shows that 4,4 '-two Isofraxidin high doses (5000 μ g/ ware) can suppress the bacterial growth of TA97, TA98, TA100, each bacterial strain of TA102, and other 4 dosage do not see that the clump count to each bacterial strain increases or inhibition.Prompting, under this experiment condition, 4,4 '-two Isofraxidins have the bacteria growing inhibiting effect when high dose, and all the other dosage do not have mutagenesis to each bacterial strain of Mus Salmonella.
Embodiment 19 4, and 4 '-two Isofraxidins bring out mammalian cell CHL chromosomal aberration test is estimated 4,4 '-two Isofraxidins with the CHL cell mutagenesis.Try to achieve earlier IC according to a conventional method
50, it is made as maximum concentration dosage, dilute successively by 0.5 multiple again, establish 3 dosage groups altogether.Experiment is at-S
9Experimental system is carried out.The IC of 4,4 '-two Isofraxidins
50Be 248 μ g/ml, its dosage setting is: 62,124,248 μ g/ml, and medicine is added cell culture directly act on to 24h, to observe 4,4 '-two Isofraxidins the CJL cell there is not mutagenesis.Result's demonstration, under this experiment condition ,-S
9In the experimental system, 4,4 '-two Isofraxidin high doses (248 μ g/ml) aberration rate is 12%, and in, the low dose group aberration rate aberration rate that is 1%, three dosage group do not demonstrate the dosage dependency relation.Repeated twice test, the result is similar.Therefore, under this experiment condition, think that 4,4 '-two Isofraxidins are weak mutagenic agent when higher dosage.
Embodiment 20 4,4 '-two Isofraxidin mouse bone marrow cells micronucleus tests
70 of ICR mices are selected in test for use, are divided into 7 groups at random, and 10 every group, male and female half and half.The mice single is irritated the MTD>5000mg/kg of stomach 4,4 '-two Isofraxidins, so maximum dose level selects 5000mg/kg, establishes 5000,2500,1250 altogether, 4 dosage groups of 625mg/kg, 1 feminine gender and 1 positive controls.Irritate stomach every day 1 time, continuous 2 days.In the 24h sampling of last dispensing back, microscopy.The result shows that under this experiment condition, 4,4 '-two Isofraxidin chemical compounds do not have the effect that the PCEMNR micronuclear rates increases of bringing out.
Embodiment 21 toxicity tests:
Considering that 4,4 '-two Isofraxidins have antifungic action, therefore in Ames test, have the bacteria growing inhibiting effect when high dose, is the pharmacodynamic action that meets itself.In the CHL chromosomal aberration test, only demonstrate weak mutagenic activity at higher dosage, if necessary, can further test definite.
The anxious malicious result of the test of mice shows in the body: the LD of 4,4 '-two Isofraxidins
50Can not survey, can only detect maximum tolerated dose is MTD>5g/kg (14 mices were observed 14 days, did not have dead), illustrates that toxicity is very little.We have detected the LD of fluconazol simultaneously
50Be about 1.6g/kg (4 mices were observed dead 2 14 days), therefore the toxicity of 4,4 '-two Isofraxidins is about littler 3 times than fluconazol.The more important thing is and do not have the effect that the mouse bone marrow cells micronuclear rates increases of bringing out.Therefore, 4,4 '-two Isofraxidins are likely a toxicity less than fluconazol, and the stronger new compound of antifungic action.
