skin pigmentation

Nonapeptide-1 (Melanostatine™ 5) can inhibit the synthesis of melanin, which makes it of interest for treating certain skin conditions.

Azelaic acid (Anchoic acid) is a component of hair and skin conditioners and is produced by the ozonolysis of oleic acid. Azelaic acid has bacteriostatic activity against Propionibacterium acnes and Staphylococcus epidermidis by inhibiting protoprotein synthesis in microbial cells. Azelaic acid also has the ability to inhibit pigmentation due to its free radical scavenging action.

γ-Oryzanol (Gamma-Oryzanol) is a natural nutrient extract isolated from rice bran oil that contains a mixture of sterols and ferulic acids, which may aid in the destruction of free radicals in the skin. It has recently been researched for its ability to slow the progress of melanin pigmentation by intercepting the ultraviolet rays at the skin's surface and hindering their transmission.

Dersimelagon (MT-7117) is an orally active, selective melanocortin 1 receptor (MC1R) agonist with EC50 values ​​of 8.16, 3.91, 1.14, and 0.251 nM for human (h), cynomolgus monkey (cm), mouse (m), and rat (r) MC1R, respectively. Dersimelagon exhibits good affinity for hMC1R and hMC4R, with Ki values ​​of 2.26 and 32.9 nM, respectively. Dersimelagon can be used in the study of skin pigmentation[1].

mTYR-IN-1 (compound 3e) is a reversible and competitive inhibitor of mTYR, with an IC50 value of 4.86 μM. This compound can be utilized in studies focused on skin pigmentation.

Nonapeptide-1 (Melanostatine-5) acetate salt is a peptide hormone that functions as a selective and competitive antagonist of the melanocortin 1 receptor (MC1R) with a binding affinity (K i) of 40 nM. It effectively inhibits α-MSH-induced increases in intracellular cyclic AMP (cAMP) and melanosome dispersion in melanocytes, with inhibitory concentrations (IC 50) of 2.5 nM and 11 nM, respectively. By inhibiting melanin synthesis, Nonapeptide-1 acetate salt is used in research related to skin pigmentation, adrenal gland steroid production regulation, and skin cancer [1] [2] [3].

Palmitoyl tetrapeptide-10 is a bioactive peptide that works synergistically with other active ingredients to increase the expression of corneodesmosin (a marker of keratinocyte adhesion) and filaggrin (a marker of keratinocyte terminal differentiation), thereby reducing skin permeability and improving skin barrier function. Palmitoyl tetrapeptide-10 can be used in research on sensitive skin syndrome and skin pigmentation.

(R)-(+)-Deoxyarbutin, an isomer of deoxyarbutin, acts as a tyrosinase inhibitor. Effective at a concentration of 21 µM, it diminishes tyrosinase activity and has been demonstrated to lighten the skin in hairless guinea pigs with dark, medium, and light pigmentation when applied at a 1% concentration.

Tyrosinase-IN-29 (compound 5c) is an effective inhibitor of abTYR tyrosinase, demonstrating an IC50 value of 6.11 μM. It is suitable for further research into the inhibition of excessive skin pigmentation.

Azelaic acid (Standard) is the standard substance of Azelaic acid, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. Azelaic acid (Anchoic acid) is a component of hair and skin conditioners and is produced by the ozonolysis of oleic acid. Azelaic acid has bacteriostatic activity against Propionibacterium acnes and Staphylococcus epidermidis by inhibiting protoprotein synthesis in microbial cells. Azelaic acid also has the ability to inhibit pigmentation due to its free radical scavenging action.

5β,6α-Dihydroxy-3β-(β-glucopyranosyloxy)-7-megastigmen-9-one (Compound 2) is a chemical compound identified in Agastache rugosa. This compound shows potential for research into skin pigmentation-related disorders.

Vinaginsenoside R4 was isolated from the leaves of hydroponically grown ginseng. It inhibits melanin biosynthesis and enhances pigmentation in zebrafish without any cytotoxic effects on melan-a cells. It may have potential as a new skin whitening compound.

Ethyl linolenate is a fatty acid ethyl ester that exhibits anti-melanogenic properties by suppressing cellular melanin synthesis with an IC50 of 70 μM.Ethyl linolenate inhibit forskolin-stimulated melanogenesis and reduces tyrosinase enzymatic activity. Its antimelanogenic profile supports the utilization of Ethyl linolenate in pigmentation disorder research and skin-lightening mechanism studies.
