NEW MATERIAL:A compound of the formula and a salt thereof.
USE: An antimicrobial agent having an inhibitory activity against β-lactamase and an ability to enhance the antimicrobial activity of an antimicrobial substance, e.g. penicillin or cephalosporin, synergistically against microorganisms capable of producing the β-lactamase.
PROCESS: A microorganism, e.g. Streptomyces sp. OA-6129 (FERM-P No.5714), belonging to the genus streptomyces, and having the ability to produce the antibiotic OA-6129B, is cultivated in a liquid nutrient culture medium at a pH of 4W9 and 20W40°C. Afther the cultivation, the microbial cell is removed by the filtration, centrifugal separation, extraction, etc., and the aimed antibiotic OA-6129B is recovered from the filtrate, supernatant liquid, extract, etc.
