説明
Imazalil is an imidazole fungicide that inhibits ergosterol biosynthesis. Imazalil inhibits the growth of various fungi in vitro including P. italicum, A. niger, U. maydis, B. alii, and C. cucumerinum in a pH-dependent manner (MICs = 0.005-2 μg/ml at pH 7). It inhibits S. cerevisiae, but not rat liver microsomal, cytochrome P450 enzymes (CYPs; IC50s = 0.088 and 80 μM, respectively), as well as aromatase CYP19 from human placental microsomes (IC50 = 0.34 μM). Imazalil activates the murine pregnane X receptor (PXR) in a concentration-dependent manner in a cell-based reporter assay. It increases hepatic CYP3A11 and CYP2B10 mRNA levels in mice when administered at a dose of 100 mg/kg. Imazalil also increases Ki-67-positive nuclei in liver sections and hepatic MCM2 mRNA levels, markers of cell proliferation, in mice when co-administered with the murine constitutive androstane receptor (mCAR) agonist TCPOBOP . Formulations containing imazalil have been used to control fungal infection in agriculture.

使用
Imazalil is a systemic fungicide with protective and curative
action. It is used for the control of a wide range of fungal diseases on fruit,
vegetables and ornamentals, powdery mildew on roses and storage
diseases of citrus fruit, pome fruit, bananas and seed potatoes. It is also
used as a seed dressing, for control of diseases of cereals (particularly
Fusarium and Helminthosporium spp.), and it is particularly active against
benzimidazole-resistant strains of plant-pathogenic fungi.

Published information is available on the metabolism of imazalil in plants
and soils. The principal metabolite in plants and soils is 1-[2-(2,4-
dichlorophenyl)-2-hydroxyethyl]-1H-imidazole.
