ML-00253764 is a melanocortin receptor 4 (MC4R) antagonist (K = 0.16 µM). It is selective for MC4R over MC3R and MC5R (ICs = 0.32, 0.81, and 2.12 µM, respectively). ML-00253764 (100 µM) decreases cAMP production induced by [NLE,D-Phe]-α-melanocyte stimulating hormone ([NDP]-α-MSH; ) by 20% in MC4R-expressing HEK293 cell membranes, but has no effect on cAMP levels in MC3R- or MC5R-expressing membranes. It prevents the loss of lean body mass and enhances light-phase food consumption in a Lewis lung carcinoma (LLC) mouse model but does not reduce tumor size when administered at a dose of 15 mg/kg.
ML-00253764 (hydrochloride) is a brain penetrant nonpeptidic melanocortin receptor 4 (MC4R) antagonist with a Ki and IC50 of 0.16 μM and 0.103 μM, respectively. ML-00253764 can cross blood-brain barrier.

ML-00253764 can inhibit the binding of NDP - α - MSH, with average IC50 values of 0.32 μM, 0.81 μM, and 2.12 μM for hMC4-R, hMC3-R, and hMC5-R, respectively.
ML-00253764 (100 μM) can reduce cAMP production induced by [NFE4, D-Phe7] - α - melanocyte stimulating hormone ([NDP] - α - MSH) by 20% in HEK293 cell membranes expressing MC4R, but has no effect on cAMP levels in cell membranes expressing MC3R or MC5R.
