Description: Selective positive allosteric modulator of M4 receptors; active in vivo; antipsychotic
Chemical Name: 3-Amino-5-chloro-N-cyclopropyl-6-methoxy-4-methylthieno[2,3-b]pyridine-2-carboxamide
Purity: ≥98% (HPLC)
Biological Activity for LY 2033298
LY 2033298 is a selective positive allosteric modulator of M4 receptor (KB = 200 nM, α = 35); increases the potency of acetylcholine by 40-fold. Exhibits no effect at hM1/3/5 receptors and a small effect at hM2 (KB = 1 μM α = 3.7). Potentiates other full and partial orthosteric agonists, including Carbachol, Oxotremorine-M, and McN-A343. Does not affect binding of antagonist NMS. Active in vivo. Antipsychotic.
α indicates the degree of allosteric enhancement when both orthosteric and allosteric sites are occupied (derived from the allosteric ternary complex model).
