title: Synthesis and antibacterial activity of 6-difluoromethoxy-7-piperazinyl-3-quinolinecarboxylic acid derivatives.
abstract: A series of novel 3-quinolinecarboxylic acid derivatives has been prepared and their antibacterial activity evaluated. These derivatives were characterized by a difluoromethoxy group attached to the 6-position and substituted piperazinyl groups attached to the 7-position.
