Isolation and characterization of acetylcholinesterase inhibitors from Piper longum L.
Background and objectives: The cholinergic deficit correlates with the severity of Alzheimer’s disease. The cholinergic function can be improved by AChE inhibitors blocking this key enzyme in the breakdown of acetylcholine. Based on traditional medicine, during two last decades the use of herbal medicinal substances in dementia therapy has been studied. The fruit extract of <em...
متن کاملPurification and characterization of an acidic, thermophilic phytase from a newly isolated Geobacillus stearothermophilus strain DM12
Microbial phytases were applied mainly to animal and human foodstuffs in order to improvemineral bioavailability and food processing. In addition, phytases have potentialbiotechnological application in various other fields, such as environmental protection,aquaculture and agriculture. Bacillus sp. DM12, an isolate from a hot spring, produces phytase,which catalyzes the hydrolysis of phytic acid...
متن کاملisolation and Characterization of an Immunosuppressive Acidic Protein from Ascitic Fluids of Cancer Patients1
Analytical isoelectric focusing in polyacrylamide gel at pH 2.5 to pH 5 was used successfully to detect an acidic protein which can be found in large quantities in the sera of cancer patients but in only small amounts ¡nthe sera of healthy persons. The main peak of this acidic protein when obtained from cancer patients revealed a pi of 3.0, while the pi of that obtained from normal subjects wa...
متن کاملIsolation, functional, and partial biochemical characterization of galatrox, an acidic lectin from Bothrops atrox snake venom.
Snake venom lectins have been studied in regard to their chemical structure and biological functions. However, little is known about lectins isolated from Bothrops atrox snake venom. We report here the isolation and partial functional and biochemical characterization of an acidic glycan-binding protein called galatrox from this venom. This lectin was purified by affinity chromatography using a ...
متن کاملIsolation and Functional Characterization of an Acidic Myotoxic Phospholipase A2 from Colombian Bothrops asper Venom
Myotoxic phospholipases A₂ (PLA₂) are responsible for many clinical manifestations in envenomation by Bothrops snakes. A new myotoxic acidic Asp49 PLA₂ (BaCol PLA₂) was isolated from Colombian Bothrops asper venom using reverse-phase high performance liquid chromatography (RP-HPLC). BaCol PLA₂ had a molecular mass of 14,180.69 Da (by mass spectrometry) and an isoelectric point of 4.4. The compl...
