MK-677 (L-163,191) je lek koji deluje kao potentan1, oralno aktivan izlučivač hormona rasta.[1][2] On oponaša GH stimulišuće dejstvo endogenog hormona grelina.[3][4] Pokazano je da povišava oslobađanje i održava povišene nivoe u plazmi nekoliko hormona među kojima su hormon rasta i IGF-1, i da nema uticaje na nivoe kortizola.[5]
On je trenutno u razvoju kao potencijalni tretman za redukciju nivoa tih hormona, kao što je nedostatak hormona rasta kod dece ili starijih odraslih osoba.[6][7][8] Klinička ispitivanja su pokazala da povećava mišićnu masu i gustinu minerala kostiju,[9][10] što ga potencijalno čini podesnim za lečenje slabosti starijih osoba.[11][12] On takođe menja metabolizam telesne masnoće tako da možda može da nađe primenu u lečenju gojaznosti.[13][14]
