| abstract | 1355487 Cephalosporanic acid derivatives and uses thereof E R SQUIBB & SONS Inc 20 June 1972 [28 June 1971] 28778/72 Heading C2A Novel 7-[(3,5,7-triaza-1-azonid-1-adamantyl) acetamido]cephalosporanic acid halides and sulphonate of the formula wherein R is hydrogen, C 1-8 alkyl, aralkyl or R 1 is hydrogen, C 1-8 alkyl, cyclo C 1-8 alkyl, unsaturated cyclo C 1-8 alkyl, monocyclic carbocyclic aryl, aralkyl, adamantyl, cycloheptatrienyl, or a monocyclic heterocyclic radical containing 5 or 6 members in the ring, the ring atoms being selected from carbon, oxygen, nitrogen and sulphur and no more than two being other than carbon; R 2 is hydrogen or C 1-8 alkyl, R 3 is C 1-8 alkyl, monocyclic carbocyclic aryl or aralkyl; X is hydrogen, hydroxy, C 1-8 alkanoyloxy, aroyloxy or aralkanoyloxy or together X and R represent a bond linking carbon and oxygen in a lactone ring and Z is chlorine, bromine or iodine or OSO 2 R 4 wherein R 4 is C 1-8 alkyl, phenyl or tolyl, and physiologically acceptable salts thereof, may be prepared by reacting hexamethylenetetramine with a compound of the formula wherein R, R 1 , R 2 , X and Z are defined as above. When R is this group may be introduced on to the 7-aminocephalosporanic acid or 7-aminodesacetoxycephalosporanic acid moiety either prior to or subsequent to the reaction with the hexamethylenetetramine by treatment with one to two moles of an appropriate halomethyl ester. Pharmaceutical, cleaning and disinfecting compositions having a broad spectrum of antibacterial activity comprise the above compounds of Formula I or a physiologically acceptable salt thereof. The pharmaceutical compositions may be administered orally or parenterally in the form of tablets, capsules, elixirs or sterile aqueous injectable solutions. |
