Description: A25822B is an azasterol antifungal agent. It may decrease the ratio of unsaturated to saturated fatty acids. The A25822 antibiotic complex consists of seven biologically active factors. A comparative study of these factors determined that factor B possessed the greatest antifungal activity. The minimal inhibitory concentration of A25822B against isolates of Candida albicans was less than 0.3 similar to 5.0 mug/ml, Trichophyton mentagrophytes was inhibited at less than 0.0312 mug/ml. Other pathogenic fungi such as Cryptococcus neoformans, Histoplasma capsulatum, Blastomyces dermatitidis, Sporotrichum schenckii, and Microsporium gypseum were very susceptible to A25822B. Only limited antibacterial activity of A25822B was found.
