ML-00253764 is a nonpeptidic melanocortin receptor 4 (MC4R) antagonist with a Ki and IC50 of 0.16 µM and 0.103 µM, respectively. Brain penetrant[1].

In Vitro

ML-00253764 displaces NDP-α-MSH binding with a mean IC50 of 0.32 μM, 0.81 μM and 2.12 μM for hMC4-R, hMC3-R and hMC5-R, respectively[1].
ML-00253764 (100 µM) decreases cAMP production induced by [NLE4,D-Phe7]-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[1].

In Vivo

ML-00253764 (subcutaneous injection; 3, 10, or 30 mg/kg; once daily) shows protection against tumor-induced body weight loss upon chronic, peripheral dosing in CT-26 tumor bearing BALB/c mice[1].
ML-00253764 dissolves in polyethylene glycol 200/saline (1:10) in a volume of 10 ml/kg[1].

Animal Model: CT-26 tumor bearing BALB/c mice[1]
Dosage: 3, 10, or 30 mg/kg
Administration: Subcutaneous injection; 3, 10, or 30 mg/kg; once daily
Result: Reduced tumor-induced weight loss in a mouse model.
