Cephalexin (Cefalexin) is a potent, orally active semisynthetic cephalosporin antibiotic with a broad antibacterial spectrum. Cephalexin has antibacterial activity against a wide variety of gram-positive and gram-negative bacteria. Cephalexin targets penicillin-binding proteins (PBPs) to inhibit bacterial cell wall assembly. Cephalexin is used for the research of pneumonia, strep throat, and bacterial endocarditis, et al .
