The bafilomycins are a family of toxic macrolide antibiotic derived from Streptomyces griseus. These compounds all appear in the same fermentation and have quite similar biological activity. Bafilomycins are specific inhibitors of vacuolar-type H+-ATPase.
The most used bafilomycin is bafilomycin A1. This is a useful tool as it can prevent the re-acidification of synaptic vesicles once they have undergone exocytosis.
Bafilomycin has antibacterial, antifungal, antineoplastic, immunosuppressive activities. In addition, bafilomycin A1 has antimalarial activity  It has been shown to decrease multi-drug resistance.
Bafilomycin B1 has been mentioned as a potential antiosteoporotic agent in treating bone lytic diseases.
