Widely used in the pharmaceutical industry, this compound, known as Cephalexin, is a first-generation semi-synthetic cephalosporin antibiotic. It exhibits broad-spectrum antibacterial activity primarily against Gram-positive bacteria and some Gram-negative bacteria. Due to its beta-lactam structure, it effectively inhibits bacterial cell wall synthesis, leading to cell lysis and death. Its application is critical in treating respiratory tract, urinary tract, skin and soft tissue infections, as well as ear, nose, and throat infections. The compound's stereochemistry enhances its stability and efficacy, making it suitable for oral formulations. It is also used in research to develop new antibiotic derivatives with improved resistance profiles against beta-lactamase enzymes.
