A series of novel N-benzylidenesulfonohydrazide compounds were designedand synthesized as inhibitors of UDP-N-acetylmuramic acid:L-alanine ligase (MurC) andUDP-N-acetylmuramoyl-L-alanine:D-glutamate ligase (MurD) from E. coli, involved inthe biosynthesis of bacterial cell-walls. Some compounds possessed inhibitory activityagainst both enzymes with IC50 values as low as 30 μM. In addition, a new, one-potsynthesis of amidobenzaldehydes is reported.

This invention belongs to the field of pharmaceutical chemistry and relates to new arylsulfonohydrazides as inhibitors of UDP-N-acetylmuramyl:L-alanine ligaze (MurC) and UDP-N-acetylmuramyl-L-alanine:D-glutamate ligaze (MurD), to procedures for their preparation and pharmaceutical preparations containing the same. The enzymes MurC and MurD are the key enzymes involved in the synthesis of bacterial peptidoglycan, so arylsulfonohydrazide inhibitors possess antibacterial activity. Compounds of general formula I
and the pharmaceutically acceptable salts are described. The appropriate substituents are clearly presented in the body of the text and in claims.
