La mayoria de las penicilinas son derivados del acido 6-aminopenicilanico, difiriendo entre si segun la sustitucion en la cadena lateral de su grupo amino. La penicilina G o bencipenicilina fue el primer antibiotico empleado ampliamente en medicina; su descubrimiento ha sido atribuido a Alexander Fleming en , quien junto con los cientificos Ernst Boris Chain y Howard Walter Florey -que crearon un metodo para producir en masa el farmaco- obtuvo el Premio Nobel en Fisiologia o Medicina en No se conoce por completo el mecanismo de accion de las penicilinas, si bien su analogia a la D-alanil-D-alanina terminal, situada en la cadena lateral peptidica de la subunidad del peptidoglicano, sugiere que su caracter bactericida deriva de su intervencion como inhibidor del proceso de transpeptidacion durante la sintesis de aquel.

De este modo, la penicilina actua debilitando la pared bacteriana y favoreciendo la lisis osmotica de la bacteria durante el proceso de multiplicacion. Existe una gran diversidad de penicilinas.
