Melatonin Receptor Antagonist

S26131 (compound 5) is a potent and selective MT1 melatoninergic ligand, and the K_i values are 0.5 and 112 nM for MT1 and MT2, respectively. S26131 behaves as an MT1 and MT2 antagonist.

S-20928 is an antagonist for melatonin receptor through inhibition of binding of melatonin to its receptors. S-20928 enhances the 2-Deoxy-D-glucose (2DG) (HY-13966)-induced increase in blood glucose and glucagon levels in rats brain.

Luzindole (Standard) is the analytical standard of Luzindole. This product is intended for research and analytical applications. Luzindole (N-0774) is a selective melatonin receptor antagonist. Luzindole preferentially targets MT2 (Mel1b) over MT1 (Mel1a) with Ki values of 10.2 and 158 nM for human MT2 and MT1, respectively. Luzindole suppresses experimental autoimmune encephalomyelitis (EAE), and exerts antidepressant-like activity.

4-P-PDOT (Standard) is the analytical standard of 4-P-PDOT. This product is intended for research and analytical applications. 4-P-PDOT is a potent, selective and affinity Melatonin receptor (MT2) antagonist. 4-P-PDOT is >300-fold more selective for MT2 than MT1. 4-P-PDOT significantly counteracts Melatonin-mediated antioxidant effects (GSH/GSSG ratio, phospho-ERK, Nrf2 nuclear translocation, Nrf2 DNA-binding activity).

GR 128107 is a competitive melatonin receptor antagonist (pK_i: 9.6).
