Abstract

New polyene macrolide antibiotic SJA-95 in free as well as liposomal (lip.) forms, with and without interferon-γ (IFN-γ) was studied in mice model of aspergillosis using biological and biochemical parameters viz. colony forming units (CFU) in liver, spleen, kidney, lung and brain, and serum IgG, and interleukin-4 (IL-4). Treatment with free and lip SJA-95 along with IFN-γ prolonged the survival time, reduced CFU in vital organs, decreased serum IgG and IL-4 levels. SJA-95 lip form showed greater antifungal activity as compared to free form. The combined treatment of lip SJA-95 with IFN-γ showed further enhancement in antifungal activity of SJA-95 (lip). The present experimental findings demonstrated IFN-γ might act as a potent modulator in immune reaction during fungal infection and can be a useful adjunctive in antifungal therapy in the management of deep seated systemic mycoses.
