| Bioactivity | ACTH (1-17) TFA, an adrenocorticotropin analogue, is a potent human melanocortin 1 (MC1) receptor agonist with a Ki of 0.21 nM. | ||||||
| Invitro | ACTH (1-17) TFA is a potent agonist at the hMC1R. ACTH (1-17) shows high affinity for the hMC1R with a Ki value of 0.21±0.03 nM which is slightly higher than that of 0.13±0.005 nM for alpha-MSH[1]. ACTH (1-17) induces a slight and not significant increase in growth hormone secretion even when micromolar concentrations of the peptide are employed in rat pituitary cultures[2]. | ||||||
