Abstract

Lipodepsipeptides from Pseudomonas syringae pv. syringae were evaluated for antifungal activity. Specifically, the in vitro antifungal and fungicidal activities of three cyclic lipodepsinonapeptides syringomycin E, syringotoxin B, and syringostatin A against medically important isolates were evaluated using a standard broth microdilution susceptibility method. Erythrocyte toxicity was also evaluated. All three compounds showed broad antifungal activity and fungicidal action against most of the fungi tested. In addition, the present invention relates to a novel method for suppressing the immune system of mammals using cyclic lipodepsipeptides. The ability of cyclic lipodepsipeptides to suppress the immune system was evaluated in mitogen-induced lymphocytes. One cyclic lipodepsipeptide, syringomycin-E significantly inhibited mitogen--induced lymphocytes stimulation by pokeweed mitogen, phytohemagglutinin, and monoclonal antibodies to CD3. These results indicate that lipodepsipeptides are useful at suppressing both cellular and humoral immune responses.
