concanamycin a

Concanamycin A (Folimycin), a polycyclic lactone antibiotic, is a selective inhibitor of vacuolar H+-ATPase (V-ATPase) and lysosomal acidification, and can be used to study inflammation.Concanamycin A enhances the immune clearance of infected progenitor cells by cytotoxic T lymphocytes, and inhibits Nef et al. from different branches of HIV and simian immunodeficiency virus. Concanamycin A enhances immune clearance of cytotoxic T lymphocytes from infected progenitor cells, inhibits the Nef allele from different branches of HIV and simian immunodeficiency virus, and can be used to study HIV infection.

Concanamycin C, a natural macrolide antibiotic, was initially isolated from Streptomyces and identified as an inhibitor of T-cell proliferation in response to concanavalin A (1,2). It exhibits cytotoxicity to fungi, including yeasts, by inhibiting vacuolar-type ATPases (3,4).
