Abstract

1,246,495. Penicillins. FARBENFABRIKEN BAYER A.G. 17 Dec., 1968 [18 Dec., 1967], No. 59874/68. Heading C2A. Novel penicillins of the general formula wherein R 1 is a nitrile radical or an acyl radical of 1-26 carbon atoms including the carboxyl carbon atom; R 2 is H, alkyl, alkyl substituted or interrupted by a heteroatom, a cycloaliphatic, aromatic or araliphatic moiety or a heterocycle; R 3 is H, alkyl, alkyl substituted or interrupted by a heteroatom, a cycloaliphatic. aromatic or araliphatic moiety or a heterocycle, or R 2 and R 3 are linked to form a cyclo. aliphatic or heterocyclic ring having 3-7 ring members, which ring may bear substituents or may have at least one other ring system fused thereto; the carbon atom marked with an asterisk being symmetrical or assymmetrical; and the pharmaceutically acceptable non-toxic salts thereof, are prepared by reacting a penicillin having one of the formulµ or salts thereof wherein R 4 , R 5 and R 6 are alkyl, aralkyl, cycloalkyl or aryl, with an acyl isothiocyanate of formula or with an N-acyl-dithiocarbamic acid derivative of the general formula wherein R 7 is alkyl, alkyl substituted or interrupted by a heteroatom, a cycloaliphatic, aromatic or araliphatic moiety or a heterocycle; or by reacting a compound of the formula or a salt or derivative thereof with an acid of formula or a functional derivative thereof in the presence of a carbodiimide, a carbonyl-diimidazole or a carbonyl-ditriazole; or by fermentation of 6-APA with glycine, glycollic acid or thioglycollic acid derivatives of an acid of the formula wherein A is -NH-, -O- or -S-. The intermediate disilylated D(-)-α-aminobenzyl penicillin is prepared by forming a solution of dried D(-)-α-aminobenzyl penicillin and triethylamine in dichloromethane and treating with trimethyl chlorosilane. Pharmaceutical compositions comprise, as active ingredient, a novel penicillin as above defined and a non-toxic diluent or carrier. The compositions may be in various forms for internal or external use. The compositions may be in dosage unit form. The novel penicillins may also be used as additives to animal fodder and as agents for the treatment of cattle mastitis.
