4-P-PDOT is a potent, selective and affinityMelatonin receptor(MT2)antagonist. 4-P-PDOT is >300-fold more selective forMT2thanMT1. 4-P-PDOT significantly counteracts Melatonin-mediated antioxidant effects (GSH/GSSG ratio, phospho-ERK, Nrf2 nuclear translocation, Nrf2 DNA-binding activity)^[1][2][3][4].

MT2 receptor^[1]

In CHO-mt1 cells the amidotetraline 4-P-PDOT (10 mM) has no effect on forskolin-stimulated cyclic AMP levels, either alone, or in the presence of Melatonin. In contrast, in CHO-MT2 cells, 4-P-PDOT is an agonist, producing a concentration-dependent inhibition of forskolin stimulated cyclic AMP, with a pEC₅₀value of 8.72 and intrinsic activity of 0.86^[1].

4-P-PDOT (0.5-1.0 mg/kg; intravenous injection;klothomutant mice) treatment significantly reverses antioxidant effects mediated by Melatonin. And significantly reverses the changes in the levels of these GSH-related parameters. 4-P-PDOT treatment significantly reverses the memory function of Melatonin-treatedklothomutant mice. 4-P-PDOT also counteracts Melatonin-mediated attenuation in response to the decreases in phospho-ERK expression, Nrf2 nuclear translocation, Nrf2 DNA-binding activity, and GCL mRNA expression in the hippocampi ofklothomutant mice^[2].
