MedKoo CAT#: 200230

CAS#: 861998-00-7 (HCl salt)

Description: Anamorelin, also known as RC-1291 or ONO-7643, is the orally bioavailable, small-molecule ghrelin mimetic with appetite-stimulating and anabolic activities. Anamorelin binds to and stimulates the growth hormone secretagogue receptor (GHSR) centrally, thereby mimicking the appetite-stimulating and growth hormone-releasing effects of grhelin. Stimulation of GHSR may also reduce the production of the pro-inflammatory cytokines TNF-alpha and interleukin-6, which may play a direct role in cancer-related loss of appetite.
