6-[.alpha.-(Imidazolidin-2-on-1-carbonylamido)acetamido]-penicillanic acids substituted in the 3-position of the imidazolidinone ring with phenyl or a substituted phenyl group and on the .alpha.-carbon atom of the acetamido bridge with a phenyl, thienyl, cyclohexenyl or cyclohexadienyl group, and their salts, are antibacterial agents. The compounds, of which .alpha.-(3-phenylimidazolidin-2-on-1-ylcarbonylamino)benzylpenicillin is a representative example, are prepared by acylation of the corresponding 6-(.alpha.-aminoacetamido)penicillanic acid or a derivative thereof.
6-[.alpha.-(咪唑啉-2-酮-1-羧酰胺基)乙酰胺基]-青霉烷酸在咪唑啉环的3位上以苯基或取代苯基取代,并在乙酰胺桥的α-碳原子上以苯基、噻吩基、环己烯基或环己二烯基取代,它们的盐是抗菌剂。该类化合物通过酰化相应的6-(α-氨基乙酰胺基)青霉烷酸或其衍生物制备,其中α-(3-苯基咪唑啉-2-酮-1-羧酰胺基)苄青霉素是一个典型的例子。
