gts-21

GTS-21 (DMXB-A) 是一种 α7 nAChR 激动剂。 GTS-21 通过抑制 RA Th1 细胞分化来抑制与类风湿性关节炎相关的炎症。

GTS-21 dihydrochloride (DMBX-anabaseine) 是一种选择性 α7 烟碱乙酰胆碱受体激动剂，具有抗炎和增强认知的活性。它也是一种拮抗剂，对人α4β2的 Ki 为20 nM，对5-HT3A 受体的 IC50为3.1 μM。

High affinity α7 nAChR partial agonist (Ki = 1.1 nM in rat; Emax < 10% of the response to ACh in rat and human). Inhibits ACh (IC50 = 2.7 nM) at α7 nAChR.
