SC-43 Inhibits Methicillin-resistant Staphylococcus aureus Through Inhibition of Heme Biosynthesis


ABSTRACT: SC-43 inhibits the key enzyme coproporphyrin ferrochelatase (CpfC) of the coproporphyrin-dependent (CPD) heme synthesis pathway and interferes with the bacterial porphyrin metabolism.

The limitations of existing drugs and the development of drug resistance make it urgent to develop new drugs against methicillin-resistant Staphylococcus aureus (MRSA). The re-development of the antibacterial activity of drugs that have already been proven safe for human use is an effective way. In this study, we discovered that the Src homology region 2 domain-containing phosphatase-1 (SHP-1) agonist SC-43, exhibits potent activity against Gram-positive bacteria, including MRSA. The mode of act  ...[more]
