A neutrophil-dependent pathway for the generation of a neutral peptide mediator: partial characterization of components and control by alpha-1-antitrypsin. [PDF]
, 1974 A biologically active neutral peptide mediator is cleaved from a plasma protein substrate by an alpha-1-antitrypsin-inhibitable serine protease apparently residing on the membrane of the human neutrophil. The peptide mediator has an approximate mol wt of

Isolation and amino acid sequence analysis of a 4,000-dalton dynorphin from porcine pituitary [PDF]
, 1982 A 4,000-dalton dynorphin was isolated from porcine pituitary. It has 32 amino acids (Mr = 3,986), with the previously described heptadecapeptide (now called dynorphin A) at its amino terminus and a related tridecapeptide, dynorphin B, at its carboxyl ...

Activity Against Pythium insidiosum and Isolated Constituents of Cordia insignis Roots
Chemistry &Biodiversity, EarlyView.This study investigates the roots of Cordia insignis in search of novel treatments for pythiosis, caused by the oomycete Pythium insidiosum. Seven compounds are isolated, including steroids, a saponin, a coumarin, a fatty acid, and a glycoside, the latter two are reported for the first time in the genus.
