Description
LY2119620 is a positive allosteric modulator of the M
2 and M
4 muscarinic acetylcholine receptors (mAChRs). It binds to allosteric sites on M
2 and M
4 receptors with K
B values ranging from 1.8 to 3.4 μM. LY2119620 potentiates the activity of the AChR agonist acetylcholine (ACh; ) and the mAChR agonists iperoxo and oxotremorine M at human recombinant M
2 and M
4 receptors expressed in CHO cell membranes. LY2119620 also exhibits allosteric agonism at M
2 and M
4 receptors (23.2 and 16.8%, respectively, of the maximal ACh response).
