(4-Methoxy-benzylidene)-(3-methoxy-phenyl)-amine, a Nitrogen Analog of Stilbene as a Potent Inhibitor of Melanin Production

TLDR
The results suggest the possibility that (4-methoxy-benzylidene)-(3-mETHoxy-phenyl)-amine might be used as a skin whitening agent.
Abstract
The current study was carried out to investigate in vitro the effects of (4-methoxy-benzylidene)-(3-methoxyphenyl)-amine on melanin biosynthesis which is closely related to hyper-pigmentation. (4-Methoxy-benzylidene)-(3-methoxy-phenyl)-amine, a nitrogen analog of stilbene, was synthesized by a single step process. This compound inhibited the tyrosinase activity, which converts dopa to dopachrome in the biosynthetic process of melanin, and showed a UV-blocking effect at UV-B band. The compound also exhibited SOD-like activity, which is involved in the protection against auto-oxidation and inhibited melanin production in melan-a cell line. Our results suggest the possibility that (4-methoxy-benzylidene)-(3-methoxy-phenyl)-amine might be used as a skin whitening agent.

A line of non-tumorigenic mouse melanocytes, syngeneic with the B16 melanoma and requiring a tumour promoter for growth.

TL;DR: An immortal line of pigmented melanocytes, “melan‐a”, has been derived from normal epidermal melanoblasts from embryos of inbred C57BL mice, providing an excellent parallel non‐tumorigenic line for studies of the cellular and molecular basis of melanoma malignancy.

The Inhibitory Effect of Glabridin from Licorice Extracts on Melanogenesis and Inflammation

TL;DR: Investigation of inhibitory effects of glabridin on melanogenesis and inflammation using cultured B16 murine melanoma cells and guinea pig skins concluded that two hydroxyl groups of gl abridin are important for the inhibition of melanin synthesis and that thehydroxyl group at the 4' position of this compound is more closely related to melan in synthesis.

Inhibitors of mammalian melanocyte tyrosinase: in vitro comparisons of alkyl esters of gentisic acid with other putative inhibitors

TL;DR: The properties of MG in vitro, including pigmentation inhibition in melanocytes, tyrosinase inhibition and selectivity, reduced cytotoxicity relative to HQ, and lack of mutagenic potential in mammalian cells, establish MG as a superior candidate skin-lightening agent.
