Hydrolysis of bradykinin by stem bromelain.
During the course of studies on the anti-edema and anti-inflammatory actions of stem bromelain, a potent kininase activity was observed (1). The present paper describes the analysis of the bonds of bradykinin which are susceptible to the action of stem bromelain. Minoh, Osaka) dissolved in 3 ml of 5 mM phosphate buffer, pH 7.5, containing 2 mM (3 mercaptoethanol, was mixed with 3 ml of purified...
متن کاملFractionation and specificity studies on stem bromelain.
The presence, in the juice of pineapples, of a proteolytic enzyme or enzymes under the name of bromelin (2) has long been known, and some of the characteristics of this enzyme have been described (3-7). The ,juice of the stem of the pineapple plant was found by Heinicke and Gortner (8) to contain a similar enzyme. The acetone precipitate from the stem juice, which is called stem bromelain,’ is ...
متن کاملProteinase activity and stability of natural bromelain preparations.
Bromelain is a complex mixture of proteinases typically derived from pineapple stem. Similar proteinases are also present in pineapple fruit. Beneficial therapeutic effects of bromelain have been suggested or proven in several human inflammatory diseases and animal models of inflammation, including arthritis and inflammatory bowel disease. However, it is not clear how each of the proteinases wi...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولAntiulcerogenic activity of stem extract and fractions of Homalium Letestui
Background & Aim: Homalium letestui Pellegr (Flacourtiaceae) used traditionally by the Ibibios of Southern Nigeria to treat stomach ulcer, malaria and other inflammatory diseases was evaluated for antiulcer properties. Experimental: The effects of ethanol stem extract of H. letestui (200 – 600 mg/kg) and fractions (Aqueous and Dichloromethane, 400 mg/kg) on experimentally in...
