Natamycin 生物活性

描述 Natamycin is an important polyene macrolide antifungal agent produced by several Streptomyces strains and is widely used as a food preservative and fungicide in food, medicinal and veterinary products[3]. Natamycin treatment was associated with significantly better clinical and microbiological outcomes than voriconazole treatment for smear-positive filamentous fungal keratitis, with much of the difference attributable to improved results in Fusarium cases[4]. The interaction of natamycin-azithromycin combination against 60 ocular fungal isolates was tested in vitro. The combination produced 100% synergistic interactions when natamycin was added to azithromycin 20, 40, and 50 μg/ml against Aspergillus flavus species complex (AFSC) isolates and to azithromycin 50 μg/ml against Fusarium solani species complex isolates. Addition of 50 μg/ml azithromycin enhanced natamycin's effect against AFSC isolates by reducing natamycin MIC90 from 64 to 0.031 μg/ml. No antagonism was observed[5]. NAT-SLNs (Natamycin solid lipid nanoparticles) were found to be non-irritating to corneal tissue. NAT-SLNs had a prolonged drug release rate, that improved corneal penetration, and increased antifungal activity without cytotoxic effects on corneal tissues. NAT-SLNs represent a promising ocular delivery system for treatment of deep corneal keratitis[6].
