Abstract
NEW MATERIAL:A compound shown by the formula I (R1 is optionally substituted nitrogen-containing hetrocyclic thio; R2 is H or OH; R3-R5 are H, OH, or acyloxy) or its compound.
EXAMPLE: 7β-[ D-2-( 6,7-Dihydroxychromono- 3-carboxyamide )-2-phenylacetamide]-3-[2-(5-methyl-1,3,4-thiadiazolyl)thiomethyl]-Δ3-cephem-4-carboxylic acid.
USE: Antimicrobial agent. Effective against Gram-positive and Gram-negative bacterium. Especially effective against Pseudomonas aeruginosa, Serratia marcescens, P- roteus morgani, etc.
PROCESS: For example, a compound shown by the formula II or its reactive derivative is reacted with a compound shown by the formula III, to give a compound shown by the formula I. The reaction is carried out in a solvent, e.g., acetone, etc., and, if necessary, in the presence of a base.
