LY2119620 is a selective positive allosteric modulator of M2/M4 receptor [1].
Muscarinic acetylcholine receptors (M1-M5) are G-protein coupled receptors regulating the action of the neurotransmitter ACh and play an important role in smooth muscle control, exocrine gland function, mood and cognition [1].
LY2119620 is a selective positive allosteric modulator of M2/M4 receptor. In [35S]GTPγS-binding experiments, LY2119620 exhibited a modest allosteric agonism of 23.2% and 16.8% at the M2 and M4 receptors, respectively. LY2119620 and ACh binding caused cooperativity factor α of 79.4 and 19.5 for the M4 receptor and the M2 receptor, respectively. The cooperativity between LY2119620 and orthosteric agonists (Iperoxo or Oxo-M) was also observed [1]. M2 receptor simultaneously bound to LY2119620 and iperoxo. LY2119620 exhibited mild negative cooperativity with the inverse agonist NMS and strong positive cooperativity with iperoxo [2]. LY2119620 significantly increased Bmax values without changes in Kd when cooperativity binding of [3H]LY2119620 with mAChR, suggesting a G protein-dependent process [3].
