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.
benzylsulfonyl hydrazides as benzylating agents has been demonstrated in the directC-3benzylation of quinoxalin-2(1H)-ones. A range of benzylsulfonyl hydrazides participated in the C-3benzylation of quinoxalin-2(1H)-ones with CuCN as the catalyst and DTBP as the oxidant, delivering structurally diverse 3-benzylquinoxalin-2(1H)-ones in moderate to good yields.
