Melanocortin Receptor Activator

Palmitoyl tetrapeptide-20 (PTP20) is a biomimetic peptide agonist of α-MSH. Palmitoyl tetrapeptide-20 promotes hair pigmentation and delays hair graying by activating the MC1-R pathway (AC₅₀: 0.16 nM), enhancing catalase activity to reduce H₂O₂ accumulation, and upregulating SIRT1 activity. Palmitoyl tetrapeptide-20 can be used in research on preventing hair loss and improving hair graying.

(D-Ser1)-ACTH (1-24) (human, bovine, mouse, ovine, porcine, rabbit, rat) is an adrenocorticotropic hormone (ACTH) analogue.

Palmitoyl tetrapeptide-20 (PTP20) TFA is a biomimetic peptide agonist of α-MSH. Palmitoyl tetrapeptide-20 TFA promotes hair pigmentation and delays hair graying by activating the MC1-R pathway (AC₅₀: 0.16 nM), enhancing catalase activity to reduce H₂O₂ accumulation, and upregulating SIRT1 activity. Palmitoyl tetrapeptide-20 TFA can be used in research on preventing hair loss and improving hair graying.

6-Methoxy-4-methylcoumarin is a 4-methylcoumarin derivative with an antitumor activity. 6-Methoxy-4-methylcoumarin activates melanin synthesis in B16F10 melanoma cells. 6-Methoxy-4-methylcoumarin is a pigmentation stimulator, and can be used for the study of skin conditions such as vitiligo.
