SPK-843, a new polyene antifungal, possessed efficacy in a murine model of systemic infection caused by Cryptococcus neoformans. The administration of 4.0 mg/kg SPK-843 led to better survival prolongation and fungal reduction than those observed with the administration of 0.7 mg/kg amphotericin B and 80 mg/kg fluconazole (P < 0.001), without histopathological renal changes.
