M40 TFA (Cat No.: I040037) is a potent and selective melanocortin receptor (MC) antagonist, widely used in neuroendocrine and metabolic disease research. It plays a crucial role in studying melanocortin signaling pathways involved in appetite regulation, energy balance, and inflammatory responses. The trifluoroacetate (TFA) salt enhances its stability and solubility for in vitro and in vivo studies. M40 TFA is valuable in exploring therapeutic strategies for obesity, metabolic syndrome, and neurological disorders, contributing to the development of targeted treatments in these fields.
