A novel, biologically active substance, poststatin, has been isolated from a culture medium of microorganism belonging to Streptomyces. The novel substance is a peptide compound having a novel structure, wherein the peptide chains have ketone radicals. Thus substance has a high endopeptidase inhibition activity. It is possible to chemically synthesize poststatin related compound having ketone radicals in the peptide chains. These compounds also have an endopeptidase inhibition activity.
一种新型生物活性物质poststatin已经从属于链霉菌的微生物培养基中分离出来。这种新物质是一种肽化合物,具有新颖的结构,其中肽链具有酮基。因此,这种物质具有较高的内肽酶抑制活性。可以通过化学合成具有肽链中酮基的与poststatin相关的化合物。这些化合物也具有内肽酶抑制活性。
