(S)-2-アミノ-3-(3,5-ジオキソテトラヒドロ-1,2,4-オキサジアゾール-2-イル)プロピオン酸 化學(xué)特性,用途語(yǔ),生産方法
説明
L-Quisqualic acid is a natural analog of glutamate that acts as an agonist at AMPA-selective and metabotropic glutamate receptors (EC
50s = 170, 10, 40, and 29 nM at GluR-A, mGluR1, mGluR3, and mGluR5, respectively), as well as the ionotropic kainate receptor (GRIK4; K
i = 6.43 nM). L-Quisqualic acid is used to study receptor dynamics and as an excitotoxin to selectively destroy neurons in the brain or spinal cord.
化學(xué)的特性
Off-White Solid
使用
Quisqualic acid is used to differentiate between mGluR-1 and mGluR-4. L-Quisqualic acid is an activator of GluR.
一般的な説明
Quisqualate/ Quisqualic acid is obtained from the fruits and seeds of
Quisqualis chinensis. It is an agonist at two subsets of excitatory amino acid receptors metabotropic receptors that indirectly mediate calcium mobilization from intracellular stores and, ionotropic receptors that directly control membrane channels. L-quisqualic acid is an agonist of the neurotransmitter L-glutamate.
生物活性
Glutamate receptor agonist acting at AMPA receptors and metabotropic glutamate receptors positively linked to phosphoinositide hydrolysis. Sensitizes neurons in hippocampus to depolarization by L-AP6 (the so called 'quis' effect). Also available as part of the Group I mGlu Receptor Tocriset™ .
純化方法
It has been purified by ion-exchange chromatography on Dowex 50W (x 8, H+ form); the desired fractions are lyophilised and recrystallised from H2O/EtOH. It has IR (KBr) : 3400-2750br, 1830s, 1775s, 1745s and 1605s cm-1;maxand 1H NMR (NaOD/D2O, pH 13) : 3.55-3.57 (1H m, X of ABX, H-2), 3.72-3.85 (2H, AB of ABX, H-3), 1 3C NMR (D2O) : 50.1t, 53.4d, 154.8s, 159.7s and 171.3s. [Baldwin et al. J Chem Soc, Chem Commun 256 1985.] It is a quasiqualate receptor agonist [Joels et al. Proc Natl Acad Sci USA 86 3404 1989].
