Antifungal phenylethylene

The antifungal and cancer cell growth inhibitory activities of 1-(3′,4′,5′-trimethoxyphenyl)-2-nitro-ethylene (TMPN) were examined. TMPN was fungicidal for the majority of 132 reference strains and clinical isolates tested, including those resistant to fluconazole, ketoconazole, amphotericin B or flucytosine. Minimum fungicidal concentration / minimum inhibitory concentration (MFC / MIC) ratios were ≦2 for 96% of Cryptococcus neoformans clinical isolates and 71% of Candida albicans clinical isolates. TMPN was fungicidal for a variety of other basidiomycetes, endomycetes and hyphomycetes, and its activity was unaffected by alterations in media pH. TMPN was slightly cytotoxic for murine and human cancer cell lines (GI50=1-4 μg / ml), and weakly inhibited mammalian tubulin polymerization (IC50=0.60 μg / ml). TMPN may also be used as a biochemical probe for tubulin and fungal dimorphism studies.

Compositions and methods using direct MMP inhibitors for inhibiting photoaging of skin

Compositions and methods are provided for ameliorating various effects of UVA and UVB radiation from the sun. The compositions include an ingredient that prevents photoaging from MED and subMED radiation, namely a direct acting MMP (matrix metalloproteinase) inhibitor. The compositions can include another, indirect MMP inhibitor, such as a retinoid, certain other compounds (such as N-acetylcysteine, 2-furildioxime, and vitamin C), tetracyclines, and if a retinoid is used then in addition optional compounds that inhibit the CYP-26 (chytochrome P-450) mediated metabolism of retinoids such as ketoconazole and other azole compounds. In the method, the composition is applied prior to exposure to the sun; for direct acting MMP inhibitors, application should be just prior to exposure, and if indirect inhibitors such as retinoids are used in addition, then application of the indirect inhibitor should be at least about seven hours prior to exposure. Compounds that prevent erythema (skin reddening, sunburn) do not necessarily protect against UV-mediated elevation of MMP levels and activity, and similarly compounds that prevent UV-mediated elevation of MMP levels and activity are not necessarily effective against UV-induced erythema.

Application of kaempferol as synergist of anti-fungal medicaments

The invention relates to the technical field of medicaments, in particular to novel application of kaempferol as a synergist of anti-fungal medicaments. The anti-fungal medicaments are azole-type or polyene-type anti-fungal medicaments and based on the effective concentration of the anti-fungal medicaments, the adding ratio of the kaempferol is 0.5 to 16 mu g / ml. Tests show that when the kaempferol and the anti-fungal medicaments such as fluconazole, ketoconazole, miconazole and amphotericin B are used together, not only the anti-fungal effect is guaranteed on the premise of lowering the consumption of the anti-fungal medicaments, but also the anti-fungal medicaments can restore the function of killing the drug-resistant fungi, so that the kaempferol can be used as a synergist of the anti-fungal medicaments. The kaempferol used as the synergist of the anti-fungal medicaments can lower the consumption of the azole-type or polyene-type anti-fungal medicaments so as to reduce the toxic and side effects of the medicaments; and the kaempferol can make the anti-fungal medicaments restore the function of killing the drug-resistant fungi, so that the kaempferol can effectively treat mycotic infection, particularly drug-resistant t mycotic infection, and has quite important clinical application values.
