    A 26771B is a 16-membered macrocyclic lactone isolated from Penicillium turbatum patented and then published by Eli Lilly and Co. in 1975. A 26771B is closely related to the berkeleylactones, recently reported as antibiotics derived from a cofermentation of P. fuscum and P. camenbertii/clavigerum. A 26771B shows potent activity in vitro against Gram-positive bacteria and moderate activity against a broad selection of fungi. A 26771B inhibits potassium dependent ATPase in rat liver mitochondria.
