Synthesis and antibacterial properties of 7-[2-(3-substituted-5-isoxazolyl)-2-methoxyiminoacetamido]cep halospora nic acid derivatives.
The synthesis of new 2-(3-substituted-5-isoxazolyl)-2-methoxyiminoacetic acids and their condensation derivatives with a suitable cephalosporanic nucleus, is reported. Their antibacterial properties were tested in vivo and in vitro also against beta-lactamase producer microorganisms; particularly the oral bioavailability of some of these new derivatives was studied.
