Elasnin, a new human granulocyte elastase inhibitor, produced by the strain of KM-2753 designated as Streptomyces noboritoensis KM--2753 has been isolated from the fermentation broth by column chromatography on silica gel and neutral alumina. Elasnin is a neutral, colorless, and viscous oil (ND17 = 1.4983, [alpha]18D -0.9 degrees, lambdaEtOHmax 291 nm (epsilon, 7,760) having a molecular formula of C24H40O4 (MW 392) as shown by its elemental analysis and mass spectrum. Elasnin markedly inhibits human granulocyte elastase, but it is almost inactive against pancreatic elastase, chymotrypsin, and trypsin. At 1.3 microgram/ml (3.3 X 10(-6) M), elasnin is 50% inhibitory to human elastase, but it causes 50% inhibition of pancreatic elastase at 30.1 microgram/ml (76.8 X 10(-6) M).

UI	MeSH Term	Description	Entries
D010179	Pancreas	A nodular organ in the ABDOMEN that contains a mixture of ENDOCRINE GLANDS and EXOCRINE GLANDS. The small endocrine portion consists of the ISLETS OF LANGERHANS secreting a number of hormones into the blood stream. The large exocrine portion (EXOCRINE PANCREAS) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the DUODENUM.
D010196	Pancreatic Elastase	A protease of broad specificity, obtained from dried pancreas. Molecular weight is approximately 25,000. The enzyme breaks down elastin, the specific protein of elastic fibers, and digests other proteins such as fibrin, hemoglobin, and albumin. EC 3.4.21.36.
