    摘要： Disclosed is a penicillin derivative of the formula:
    wherein n is an integer of 0, l or 2; Y is a cyano group, a lower acyl group, a mono- or di-lower alkylthiocarbamoyl group,
    wherein R₁ is a hydrogen atom, a lower alkyl group, a phenyl group, a group -(CH₂) m -OR₂ or -(CH₂) m COOR₂ (m is an integer of l to 6 and R₂ is a hydrogen atom or a penicillin carboxyl ester-forming group which is commonly used for penicillin derivatives) or a phenyl group substituted by at least one member selected from the class consisting of lower alkyl group, halogen atom and lower alkoxy group; and R is a hydrogen atom or a penicillin carboxyl ester-forming group, or a salt thereof. They are useful as β-lactamase inhibitors.
