Objective：To observe the in vitro and in vivo antifungal activity of a triadimenol compound SL-130.Methods: The M27-A project recommended by the National Committee for Clinical Laboratory Standard (NCCLS) in 1997 was used in the present study.The minimum inhibitory concentrations (MIC80) of SL-130 were determined for candidal and non-candidal strains with different susceptibilities to fluconazole.Agar disk diffusion test,time-kill curves test and mouse survival rate were employed to examine the antifungal activity of SL-130.Results: The results indicated that SL-130 had stronger in vitro antifungal activity than fluconazole，and similar in vivo activity to fluconazole.Conclusion:The structure of SL-130 is quite unique and it has in vitro and in vivo antifungal activity; further study is warranted on the compound.
