GBR-14206, a new imidazole derivative, has been evaluated against systemic infection with Candida albicans in normal and immunocompromised mice. The therapeutic effect of GBR-14206 (as a lipid emulsion) given intravenously to mice infected systemically with C. albicans was superior to that of miconazole. GBR-14206 also showed a candicidal effect in the blood stream at the therapeutic dose. In addition, GBR-14206 inhibited the hyphal growth (yeast to hyphal transformation) in Eagle's minimum essential medium and methionine synthetic medium at the respective concentrations of 0.20 and 0.05g/ml, which were approximately 3 to 7 times more active than miconazole.These properties suggested that GBR-14206 may be useful for the therapy of systemic candidiasis in human.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
