What is (D-ALA2)-Leucine Enkephalin?

(D-ALA2)-Leucine Enkephalin is commonly dispersed in the human body as well as has extremely crucial physiological attributes. It not simply has an unique effect on mind cells, it can activate brain cells in a resting state, as well as additionally has an exceptional recovery effect on sequelae brought on by mind injury; it plays an important role in immune feature, including enhancing the body immune system, T The task of lymphocytes, NK cells, macrophages, and more, anti-virus, improve the launch of γ-interferon, and so on; the switched on immune cells can promote the secretion of endocrine cells to sign up with immune standard, consequently influencing the genetics regulation and expression function of DNA.

(D-ALA2)-Leucine Enkephalin Uses

(D-ALA2)-leucine enkephalin is a natural synthesis intermediate as well as a pharmaceutical intermediate, which can be made use of in the process of lab organic research and development and chemical and pharmaceutical research and development, especially in the process of biochemical research and development.

(D-ALA2)-Leucine Enkephalin Assay Method

Xia Yuqin et al. established a novel redox precolumn derivatization fluorescence detection high performance liquid chromatography method for the determination of (D-ALA2)-leucine enkephalin drugs. Methods The (D-ALA2)-leucine enkephalin was mixed with 0.012mol/L sodium periodate, 0.01mol/L catechol and 0.3mol/L boric acid in a volume ratio of 2:2:1:1, After reacting at 120℃ for 10min, the samples were separated by reversed-phase column, with 0.25mol/L borate buffer (pH 7.6) and methanol as mobile phases, gradient elution was adopted, and fluorescence detector was used for detection. At the same time, the content of L-EK in vitro and in blood samples was determined by comparing with high performance liquid chromatography UV method and O-phthalaldehyde (OPA) pre-column derivatized fluorescence detection high performance liquid chromatography.

Results The redox-column derivatization fluorescence detection high performance liquid chromatography was used to detect (D-ALA2)-leucine enkephalin in blood samples, the linear range was 0.5-50.0 mg/L, and the linearity was good (r=0.999 8). The detection limit was 0.1 mg/L, and compared with the other two methods, it was not disturbed by endogenous substances. Conclusion The novel redox precolumn derivatization fluorescence detection high performance liquid chromatography has good specificity and high sensitivity, especially suitable for the determination of (D-ALA2)-leucine enkephalin in biological samples.

Effects of (D-ALA2)-Leucine Enkephalin and its Analogues on Gastric Secretion

The result of enkephalin analogs on gastric secretion was explored. Histamine-stimulated gastric secretion was found to be significantly boosted intoxicated of the enkephalin analog Tyr-D-Ala-Gly-Phe-(NO2)NH2. The enkephalin analog Tyr-Gly-Gly-Phe-Leu-D-Arg increased the amount of stomach juice as well as pepsin secretion, yet the debit of hydrochloric acid was lower than in try outs histamine mixture alone. One more enkephalin analog, Tyr-D-Ala-Gly-Phe-D-Leu-Arg, presented at the same time as histamine, considerably minimized gastric secretion just 90-105 minutes after the begin of perfusion.
