A 54556B is an unusual depsipeptide isolated from Streptomyces hawaiiensis as antibiotics by researchers at Eli Lilly in 1985, featuring a trienone side chain. A 54556B is a potent antibacterial against Gram positive and Gram negative bacteria including MRSA. A 54556B is a member of the recently re-discovered acyldepsipeptide (ADEP) antibiotics that act by activating and disregulating Clp-family proteins. ADEPs are considered important leads in the development of new generations of antibiotics against resistant bacteria.
