Abstract
The present invention relates to 7- (Z) -2- (aminothiazol-4-yl) -2- ( -Carboxy-3,4-substituted benzyloxyimino) acetamide group and at the same time introduced with an ethene group substituted by a heterocycle at the C-3 position, has strong microbial activity, broad spectrum antimicrobial spectrum and improved pharmacokinetic properties A physiologically hydrolyzable ester, a solvate thereof, an isomer thereof, and an antimicrobial agent composition containing the same as an active ingredient.
Represents the above formula, Q is CH or N, R 1 represents a hydrogen or an amino protecting group, R 2 and R 3 are the same or different, each independently represent hydrogen or a hydroxy protecting group, the R 2 and R 3 Together form a cyclic diol protecting group, R 4 and R 5 represent hydrogen or a carboxyl protecting group, R 6 represents a heterocyclic compound of the following formula,
Wherein R 7 and R 8 are each independently hydrogen, substituted or unsubstituted amino, hydroxy, alkoxy, C 1 -C 4 alkyl, carboxylalkoxycarbonyl or halogen, R 9 is C 1 -C 4 Alkyl, C 3 -C 4 alkenyl, carboxymethyl or amino.
