Use of Astat

Lanoconazole is a potent and orally active imidazole antifungal agent, shows a broad spectrum of activity against fungi in vitro and in vivo[1]. Lanoconazole interferes with ergosterol biosynthesis by inhibiting sterol 14-alpha demethylase and blocking fungal membrane ergosterol biosynthesis. Lanoconazole can be used for the investigation of dermatophytosis and onychomycosis[1][2].

Target	IC50: antifungal[1]
In Vivo	Lanoconazole (treatment for ear; 0.3%-3%; 6 days) dose‐dependently suppressesTPA-induced irritant dermatitis, suppresses the production of neutrophil chemotactic factors such as keratinocyte‐derived chemokine and macrophage inflammatory protein‐2, and inhibited neutrophil infiltration to the inflammation site[2]. Lanoconazole (oral administration; 3, 10 or 30 mg/kg; once a day; 3 weeks) significantly inhibits C. neoformans compared with the saline control in normal mice. In addtion, it significantly reduces the growth of C. neoformans in the lungs and brains of MAIDS mice[3]. Animal Model: BALB/c mice[2] Dosage: 0.3%-3% dosage Administration: Treatment for ear Result: Exhibited an inhibition effect of LCZ on ear swelling induced by topical application of TPA in mice. Animal Model: Four week old C57BL/6 mice infected intraperitoneally with LP-BM5 murine leukaemia virus[3] Dosage: 3, 10 or 30 mg/kg Administration: Oral adminstration Result: Inhibited C. neoformans growth in both normal and C. neoformans -induced encephalitis MAIDS mice .
