Abstract
- Nikkomycin Z is a competitive inhibitor of chitin synthases in fungi. It has been reported that it inhibits chitin synthases (Chs) 1 and 3, but not 2, of Saccharomyces cerevisiae. In our study, we found that: (a) nikkomycin Z inhibited all three Chs isozymes of Candida albicans (CaChs). The IC(50) value for CaChs1 is 15microM, for CaChs2 0.8microM, and for CaChs3 13microM; (b) nikkomycin Z inhibits vegetative growth of C. albicans differently in different growth media; growth inhibition was observed on Spider and corn meal agar plate, but not on Lee's plate; (c) growth inhibition by nikkomycin Z accompanied by the absence of septum and cell wall chitin, which in turn brought about cell lysis. Nikkomycin Z did not lyse cells in Lee's media and lysis was partially prevented in the presence of sorbitol as an osmostabilizer in Spider medium. Therefore, nikkomycin Z prevented the formation of septum and cell wall chitin by inhibiting chitin synthase activities in a growth medium-dependent manner.<br /> (Copyright 2002 John Wiley & Sons, Ltd.)
