| Description | Nonapeptide-1 (Melanostatine-5), a peptide hormone, is a selective antagonist of MC1R (Ki: 40 nM). Nonapeptide-1 is a competitive α-MSH antagonist that potently inhibits intracellular cAMP and melanosome dispersion induced by α-MSH in melanocytes (IC50: 2.5 nM and 11 nM, respectively). Nonapeptide-1 (Melanostatine-5), a peptide hormone, is a selective antagonist of MC1R (Ki: 40 nM). Nonapeptide-1 is a competitive α-MSH antagonist that potently inhibits intracellular cAMP and melanosome dispersion induced by α-MSH in melanocytes (IC50: 2.5 nM and 11 nM, respectively). Nonapeptide-1 inhibits melanin synthesis, and can be used in the research of skin pigmentation and regulation of steroid production in the adrenal gland, skin cancer[1][2][3]...

Avidin has excellent affinity with biotin and is often used in combination with biotin for immunoassays to detect the location of antigens in tissues[1] | Leucine dehydrogenase, Microorganism (EC 1.4.1.9) can be purified from Bacillus spheroides. Leucine dehydrogenase catalyzed the oxidative deamination of L-leucine, L-valine, L-isoleucine, L-norvaline, L-alpha-aminobutyrate, and L-norleucine, and the reductive amination of their keto analogues[1] | Octreotide (SMS 201-995) is a somatostatin receptor agonist and synthetic octapeptide endogenous somatostatin analogue. Octreotide (SMS 201-995) can bind to the somatostatin receptor and mainly subtypes 2, 3, and 5, increases Gi activity, and reduces intracellular cAMP production. Octreotide (SMS Octreotide (SMS 201-995) is a somatostatin receptor agonist and synthetic octapeptide endogenous somatostatin analogue. Octreotide (SMS 201-995) can bind to the somatostatin receptor and mainly subtypes 2, 3, and 5, increases Gi activity, and reduces intracellular cAMP production. Octreotide (SMS 201-995) has antitumor activity, mediates apoptosis and may also be used in disease studies in acromegaly[1][2]...

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 (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[1]... Read More |
