Antibiotic U-64846 is a new entity with the molecular formula C18H35ClN4O9 (MW 486). It is a very water soluble, reddish solid which decomposes above 300°C and which is air-sensitive. The antibiotic is produced by Streptomyces braegensis and it inhibits a variety of Gram-positive bacteria. Acidic hydrolysis gave 3, 7-diaminoheptanoic acid. The antibiotic gives 1H NMR, 13C NMR, IR and UV spectra which indicate it is not closely related to known antibiotic families.
