Description
PHARMACOLOGICAL CLASS
Melanotan 2 is in the class of alpha melanocyte-stimulating hormone (alpha-MSH) mimetics. Alpha-MSH is produced in the pituitary, and activates alpha- melanocyte receptors. MT-II works in the same way. There are a number of subtypes of alpha-melanocyte receptors (MC1-5.) Melanotan Il is generally non-selective and activates multiple types. Activation of the MC1 receptor promotes skin pigmentation, while activation of the MC4 receptor can enhance tendency to penile erection. PT-141 is selective in comparison with the MC4 receptor and therefore promotes penile erection while having little or no effect on skin
pigmentation.
