چکیده
SPK-843, a new polyene antifungal, exhibited dose-dependent efficacy on murine pulmonary aspergillosis models. SPK-843 doses of higher than 1.0 mg/kg of body weight exhibited no renal toxicities and a tendency toward better survival prolongation than the estimated maximum tolerated doses of amphotericin B (Fungizone) (1.0 mg/kg) and liposomal amphotericin B (AmBisome) (8.0 mg/kg).

Efficacy of SPK-843, a novel polyene antifungal, in a murine model of systemic cryptococcosis.
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.
متن کاملEfficacy of combination antifungal therapy with intraperitoneally administered micafungin and aerosolized liposomal amphotericin B against murine invasive pulmonary aspergillosis.
Targeted intrapulmonary delivery of drugs may reduce systemic toxicity and improve treatment efficacy. In the current study, we evaluated the effects of a combination treatment consisting of inhalation of aerosolized liposomal amphotericin B (L-AMB) with intraperitoneal administration of micafungin (MCFG) against murine invasive pulmonary aspergillosis. The combination of aerosolized L-AMB with...
متن کاملEfficacy of single-dose liposomal amphotericin B or micafungin prophylaxis in a neutropenic murine model of invasive pulmonary aspergillosis.
In a neutropenic murine model of invasive pulmonary aspergillosis, prophylaxis with single doses of liposomal amphotericin B or micafungin at >or=5 mg/kg of body weight improved animal survival and suppressed the lung fungal burden for up to 7 days after infection, demonstrating the potential utility of infrequent dosing with these antifungals.
متن کاملCombination echinocandin-polyene treatment of murine mucormycosis.
We previously found that caspofungin synergized with amphotericin B lipid complex in treating murine mucormycosis. We now report a similarly enhanced activity of liposomal amphotericin combined with micafungin or anidulafungin in mice with disseminated mucormycosis. The efficacy of combination echinocandin-polyene therapy for mucormycosis is a class effect.
متن کاملDelay of antifungal therapy influences the outcome of invasive aspergillosis in experimental models of infection.
OBJECTIVES The aim of the present study was to evaluate the effects of delayed antifungal therapy on the outcome of invasive aspergillosis due to Aspergillus fumigatus in experimental models of infection. METHODS A clinical isolate of A. fumigatus susceptible to amphotericin B (MIC 0.5 mg/L) and micafungin [minimum effective concentration (MEC) 0.03 mg/L] was used in all experiments. Two mode...
