Nikkomycin Z is an antifungal drug that inhibits chitin synthase. It has been reported that it inhibits chitin synthases (Chs) 1 and 3, but not 2, of Saccharomyces cerevisiae. Later it was found that nikkomycin Z inhibited all three Chs isozymes of Candida albicans (CaChs). The IC(50) value for CaChs1 is 15 uM, for CaChs2 0.8 uM, and for CaChs3 13 uM. Nikkomycin Z is under development as an orphan product for treatment of coccidioidomycosis. Nikkomycin Z has been used in trials studying the treatment and basic science of Coccidioidomycosis. In February 2006, nikkomycin z was designated as an orphan drug for the treatment of Coccidioidomycosis.

Sample Use Guides

In Vivo Use Guide

Safety and pharmacokinetics of nikkomycin Z were evaluated in healthy male subjects following single, rising oral doses ranging from 250 mg to 2,000 mg. Pharmacokinetics appeared linear over the range of 250 to 500 mg; however, relative bioavailability was about 62 to 70% for the 1,000-mg dose and 42 to 47% for doses between 1,500 and 2,000 mg.
