TMN-OMe
TMN-OMe is a blood-brain barrier-permeable GPR39 agonist and a radiotracer for positron emission tomography (PET). TMN-OMe activates GPR39 by recruiting β-arrestin, exhibits highly selective binding ability in the mouse brain, and enables quantitative analysis of GPR39 at the in vivo level. TMN-OMe shows specific uptake in GPR39 knockout mice, Alzheimer's disease model (APP/PS1) mice, and blocking experiments. TMN-OMe facilitates in-depth exploration of changes in GPR39-related mechanisms in neurological diseases and is widely used in Alzheimer's disease research.

Biological Activity
TMN-OMe (5 nM-33.3 μM; 2 h) activates human GPR39 expressed in CHO-K1 cells with an EC50 of 1.65 μM in a β-arrestin recruitment assay[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
[11C]TMN-OMe (8.5 MBq; i.v.; single bolus injection) detects reduced GPR39 levels in the brains of APP/PS1 Alzheimer's disease model mice[1].
