生物活性
描述 Ketoconazole, an imidazole anti-fungal agent, has often produced features of androgen deficiency including decreased libido, gynecomastia, impotence, oligospermia, and decreased testosterone levels, in men being treated for chronic mycotic infections[6]. It also inhibits arachidonic acid lipoxygenases and cytochrome P-450 enzymes[7]. Ketoconazole competed with [3H]methyltrienolone (R1881) for androgen binding sites in dispersed, intact cultured human skin fibroblasts[6]. In the serum independent HT29-S-B6 colon cell clone, ketoconazole reduced cell proliferation and [3H]thymidine incorporation in a dose-dependent fashion, with a 50% inhibitory concentration of approximately 2.5 μM. It also inhibited [3H]thymidine incorporation in the hormone-independent breast cancer cells MDA-MB-231 and Evsa-T, with respective 50% inhibitory concentration of approximately 13 and 2 μM. In addition, ketoconazole induced a dose-dependent decrease of the number of cells in S phase within 24 h of treatment (from 17 to 3%) and a corresponding increase of the percentage of cells in Go-G1 (from 64 to 80%)[7]. All strains of the seven Malassezia species were susceptible to ketoconazole at low concentrations. M. furfur, M. sympodialis, M. slooffiae, M. pachydermatis, M. globosa, M. obtusa and M. restricta were most sensitive to it with minimum inhibitory concentrations (MICs) ranging from < or = 0.03 to 0.125 μg/mL[8]. Pretreatment with ketoconazole (25 mg/kg, i.p.) significantly decreased plasma corticosterone and reduced low dose (i.e. 0.125 - 0.25 mg/kg per infusion) cocaine self-administration without affecting food-reinforced responding[9]. Ketoconazole raised the AUC of orally administered digoxin from 63 ± 17 to 411 ± 50 μg•h/l. When given intravenously, digoxin AUC increased from 93 ± 22 to 486 ± 26 μg•h/l with ketoconazole administration[10].
