Abstract
The invention relates to [alpha]-thienyl-oxymethyl penicillins of formula wherein R1 and R2 are hydrogen or methyl and R3 is hydrogen, methyl or ethyl. The penicillins are produced by reacting 6-aminopenicillanic acid, or a salt thereof, with an [alpha]-thienyloxycarboxylic acid of formula or a functional derivative thereof, wherein R1, R2 and R3 have the above meanings and, if desired, liberating the free acid from the salt obtained or converting the free acid into a physiologically tolerable salt. Alkali metal, alkaline earth metal, ammonium and amine salts are specified. A typical penicillin is 6-[[alpha]- (thienyl - (3) - oxy) - butyrylamino]-penicillanic acid. The penicillins are acid-stable and have outstanding antibacterial activity. A pharmaceutical composition for human and animal use comprises one of the above [alpha]-thienyloxymethyl penicillins or a salt thereof, and a carrier.
