CRS-3123, also known as REP-3123, is a methionyl-tRNA synthetase inhibitor potentially for the treatment of enteric infections. CRS-3123 is in Phase 1 clinical development for the treatment of Clostridium difficile Infection (CDI). CRS-3123 is a small molecule protein synthesis inhibitor that acts on the novel target methionyl-tRNA synthetase (MetRS). REP-3123 has been shown to be active in vitro against clinical isolates of C. difficile including epidemic strains such as B1/ NAP1/027; MIC values of REP-3123 for C. difficile are typically 0.5 -- 1.0 mg/l. REP-3123 is also active against a range of clinically important aerobic Gram-positive bacteria including methicillin-susceptible and -resistant Staphylococcus aureus (MIC90 values of 0.06 and 0.25 mg/l, respectively), Streptococcus pyogenes (MIC90 0.5 mg/l) and enterococci (MIC90 32 mg/l). CRS-3123 has numerous potential advantages over current CDI therapies. In addition to being highly potent against all clinical isolates of C. difficile tested, CRS-3123 has several desirable qualities for the treatment of CDI which include: Narrow spectrum for C. difficile, which may substantially reduce the disruption of normal intestinal flora compared to current therapies; Inhibition of toxin production, potentially leading to lower morbidity and mortality; Inhibition of sporulation, potentially leading to lower rates of transmission and recurrence; A novel mechanism of action, which means that its use will not compromise the utility of systemic antibiotics while maintaining activity against pre-existing resistance mechanisms.

Targets:

N(ω)-hydroxy-nor-L-arginine (nor-NOHA), an arginase inhibitor, has therapeutic potential in the treatment of cardiovascular and obstructive airway diseases. Nor-NOHA is a reversible, competitive arginase inhibitor. The affinity of nor-NOHA for the to the arginase active site was found in the nanomolar range. Nor-NOHA has proven to be one of the strongest arginase inhibitors. Inhibition by nor-NOHA is ten times more potent on arginase II than on arginase I. The pharmacokinetics of nor-NOHA is characterized by high bioavailability, close to 100% after multiple dose and rapid elimination resulting in t1/2 of 15–30 min after intravenous and intraperitoneal administration to rats. Arginase inhibition with Nor-NOHA increased circulating arginine levels and decreased hepatic damage during liver I/R injury. Arginase blockade represents a potentially novel strategy to combat hepatic I/R injury associated with liver transplantation. Nor-NOHA is under investigation in clinical trial NCT02009527 (Arginase inhibition in ischemia-reperfusion injury).
