5-Amino-1MQ is a small molecule inhibitor of nicotinamide N-methyltransferase (NNMT), an enzyme that catalyzes the transfer of a methyl group from S-adenosylmethionine (SAM) to nicotinamide, generating 1-methylnicotinamide (1-MNA). By inhibiting NNMT, 5-Amino-1MQ increases intracellular NAD+ levels, reduces 1-MNA production, suppresses lipogenesis in adipocytes, and modulates the methionine-homocysteine cycle. In vivo, it significantly reduces body weight, white adipose mass, and adipocyte size through enhanced energy expenditure and altered lipid metabolism.

PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide melanocortin analog that acts as an agonist at MC3R and MC4R melanocortin receptors, with higher affinity for MC4R. It enhances sexual desire by activating presynaptic MC4Rs on neurons in the medial preoptic area (mPOA) of the hypothalamus, increasing dopamine release — an excitatory neurotransmitter for sexual desire. Unlike PDE5 inhibitors, PT-141 works centrally through the CNS rather than peripherally on blood flow, addressing desire rather than just erectile mechanics.
