    • NEW MATERIAL:An antibiotic PA-39504-X
      3 expressed by the formula and a pharmacologically acceptable salt thereof.
      USE: An antimicrobial agent, having an antimicrobial activity against Gram-positive and Gram-negative bacteria and inhibitory action on β-lactamase production, and administered orally or parenterally in a dose of 0.1W30g/day in the case of the subcutaneous administration.
      PROCESS: A strain, belonging to the genus Streptomyces, and having the ability to produce an antibiotic PA-39504-X
      3 , e.g. Streptomyces sp. PA-39504 (FERM-P No.5265), is cultivated in a liquid nutrient culture medium under aerobic conditions, and the antibiotic PA-39504-X
      3 is separated and collected from the resultant culture after the completion of the cultivation. Alternatively, the antibiotic PA- 39504-X
      3 can be obtained by refluxing an antibiotic PA-31088-IV in carbon tetrachloride with triphenylphosphine under mild conditions, and deoxidizing the reaction product.
