Cefalexin (cephalexin) is one of the most widely used antibiotic medications. It is a first-generation cephalosporin type of antibiotic drug, that is sold under nearly 100 brand names.

Chemistry

An IUPAC chemical name of cefalexin is (6R,7R)-7-[[(2R)-2-amino-2-phenylacetyl]amino]-3-methyl-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid. Its chemical formula, C16H17N3O4S, gives it an average molecule mass of 347.3890 gram/mole. Its antibacterial activity is due to the core beta-lactam structure, which bind with penicillin-binding proteins within bacteria, thereby inhibiting bacterial cell wall synthesis, by an acylation reaction of the lactam with the bacterial proteins.
