PT-141 (Bremelanotide)- Summary
- 5-Amino-1MQ is a small-molecule NNMT (Nicotinamide N-methyltransferase) inhibitor that raises intracellular NAD+ levels and promotes fat burning. It is notable for targeting adipose tissue directly, reducing fat cell size and number while increasing metabolic rate.
- PT-141 (Bremelanotide) is a cyclic peptide melanocortin receptor agonist that enhances sexual desire and arousal through central nervous system mechanisms. It is FDA-approved as Vyleesi for premenopausal women with hypoactive sexual desire disorder (HSDD).
