General description

An antifungal antibiotic that inhibits protein synthesis in eukaryotes but not in prokaryotes. Interacts directly with the translocase enzyme, interfering with the translocation step. Inhibits cell-free protein synthesis in eukaryotes. Competitively inhibits hFKBP12 (Ki = 3.4 µM). Triggers apoptosis in HL-60 cells, T-cell hybridomas, Burkitt′s lymphoma cells, and a variety of other cell types, including rodent macrophages. Induces DNA fragmentation in macrophages, however it inhibits DNA cleavage in rat thymocytes treated with thapsigargin, methylprednisolone, and ionomycin. Rapidly destroyed in alkaline solutions.
