A bioactive component, 2′,3,4,4′-tetrahydrochalcone (RY3-a) was first isolated from Vernohia anthelmintica (L.) willd seeds, and a set of its analogs, RY3-a-1–RY3-a-15 and RY3-c were designed and synthesized. Biological activity assays showed that RY3-c exhibited better melanogenesis and antioxidant activity and lower toxicity in comparison with RY3-a and butin. Further study tests showed that RY3-c exhibited better melanogenesis activity compared with the positive control 8-methoxypsoralan (8-MOP) in a vitiligo mouse model, suggesting that RY3-c is a good candidate antivitiligo agent. Mechanistic studies showed that RY3-c could repair cell damage induced by excessive oxidative stress and may exert melanin synthesis activity in the mouse melanoma B16F10 cell line by activating the mitogen-activated protein kinase (MAPK) pathway and the upregulation of c-kit.

PROBLEM TO BE SOLVED: To provide a polymerizable compound that exhibits excellent dissolvability with other liquid crystal compounds when it constitutes a polymerizable liquid crystal composition and that exhibits excellent heat resistance and mechanical strength when the polymerizable liquid crystal composition is cured. SOLUTION: The compound represented by general formula (I) is useful as a constituting member of a polymerizable composition as it has excellent dissolvability with other liquid crystal compounds. The polymerizable liquid crystal composition comprising the polymerizable compound has a wide liquid crystal phase temperature range. The optical anisotropic body obtained by using the polymerizable composition exhibits high heat resistance and is useful for applications such as a polarizing plate, a retardation plate and the like.
