Abstract

gamma-Chloronorvaline (AL-719) and gamma-hydroxynorvalinelactone (AL-719Y) were isolated from the culture broth of Streptomyces griseosporeus AL-719. Physico-chemical studies led to the structure elucidation of AL-719 and 719Y, with there respective configurations of (2S, 4S) and (2S, 4R). AL-719 shows Antibacterial activity on a synthetic agar, especially against Pseudomonas aeruginosa, which was reversed by L-leucine. The producing strain AL-719 was characterized.
