Abstract

NEW MATERIAL:A penicillanic acid shown by the formula I (X is S or S→O) and its salt. EXAMPEL:6-[ D-( - )-α-(4-hydroxy-7,8-dihydro-5H-thiopyrano[ 4,3-b ]pyridine-3- carboxylamide)-phenylacetoamide]penicillanic acid.
USE: An antibacterial agent. Useful as a drug for bacterially caused disease of a mammal and as a bactericide. Having a wide range of antibacterial spectacle and high antibacterial activity against gram-negative bacterium, especially against any bacterium of the genus pseudomonas.
PROCESS: An ampicillin shown by the formula II, its salt, or its reactive derivative, is reacted with a reactive derivative shown by the formula III of quinolinecarboxylic acid, e.g., an acid halide, a mixed acid anhydride, an activated ester, etc. in a solvent, e.g., tetrahydrofuran, methylene dichloride to give a compound shown by the formula I.
