<p>A prolyl endopeptidase inhibitor SNA-115, which is a peptide represented by C113H142N26O27. An SNA-115 producing bacterium belonging to Microbispora sp. A process for producing SNA-115 by culturing the SNA-115 producing bacterium. A prolyl endopeptidase inhibitor SNA-115T, which is a peptide represented by C113H144N26O28 and produced by hydrolyzing SNA-115 with trypsin. SNA-115 and SNA-115T have a prolyl endopeptidase inhibiting activity and are useful as an active ingredient for preventing and treating amnesia, acquired immunodeficiency syndrome (AIDS) and HIV diseases.</p> |
