Anidulafungin (LY-303366)is a synthetic derivative of echinocandin B, used as a drug of antifungal [1].
Anidulafungin has been reported to inhibit systemic isolates of Candida species with the MIC90 values of 0.08μg/ml, 0.32μg/ml, 0.32μg/ml and 5.12μg/ml for C.albicans (n=99), C.glabrata(n=18), C.tropicalis(n=10), and C.parapsilosis (n=10), respectively. In addition, Anidulafungin has been found to be active against Aspergillus species(n=20) with the MIC90 values of ~0.02μg/ml. Apart from these, Anidulafungin has been revealed to inactively restrain with the MIC90 values of >10.24μg/ml and 16μg/ml, for C.neoformans and B.dermatitidis, respectively [1].
