MDA 19

CAS No. : 1048973-47-2

MCE 站：MDA 19

产品活性：MDA 19 是一种有效和选择性的人类大麻素受体 2 (CB2) 激动剂，K_i 值为 43.3 nM。MDA 19 在神经性疼痛的大鼠模型中具有抗痛觉过敏作用，并且不影响大鼠的运动能力。

研究领域：GPCR/G Protein  |  Neuronal Signaling

作用靶点：Cannabinoid Receptor

In Vitro: MDA19 displayed 4-fold-higher affinity at the human CB(2) than at the human CB1 receptor (K(i) = 43.3 +/- 10.3 vs 162.4 +/- 7.6 nM) and nearly 70-fold-higher affinity at the rat CB2 than at the rat CB1 receptor (K(i) = 16.3 +/- 2.1 vs 1130 +/- 574 nM). In guanosine triphosphate (GTP)gamma[(35)S] functional assays, MDA19 behaved as an agonist at the human CB1 and CB2 receptors and at the rat CB1 receptor but as an inverse agonist at the rat CB2 receptor. In 3',5'-cyclic adenosine monophosphate (cAMP) assays, MDA19 behaved as an agonist at the rat CB1 receptor and exhibited no functional activity at the rat CB(2) receptor. In extracellular signal-regulated kinases 1 and 2 activation assays.

In Vivo: MDA19 behaved as an agonist at the rat CB2 receptor. MDA19 attenuated tactile allodynia produced by spinal nerve ligation or paclitaxel in a dose-related manner in rats and CB2(+/+) mice but not in CB2(-/-) mice, indicating that CB2 receptors mediated the effects of MDA19. MDA19 did not affect rat locomotor activity.
