CRS-3123（Cat No.: I006300）is a novel antibacterial agent targeting Clostridioides difficile infections. It works by inhibiting methionyl-tRNA synthetase, an enzyme essential for bacterial protein synthesis, leading to disrupted translation and bacterial growth arrest. CRS-3123 exhibits a narrow-spectrum profile, effectively targeting C. difficile while sparing the gut microbiota, reducing the risk of dysbiosis. Its unique mechanism of action and low potential for resistance make it a promising candidate for treating antibiotic-resistant infections. CRS-3123 is a valuable tool in research on targeted antibacterial therapies and microbiome preservation.
