trans-Caffeic acid stearyl ester from Paeonia suffruticosa inhibits melanin synthesis by cAMP-mediating down-regulation of alpha-melanocyte-stimulating hormone-stimulated melanogenesis signaling pathway in B16 cells.[Pubmed:23207771]
Biol Pharm Bull. 2012;35(12):2198-203.
Trans-caffeic acid stearyl ester (TCASE) from the root cortex of Paeonia suffruticosa ANDREWS is a traditional medicinal herb that has several beneficial properties. However, the inhibitory effect of TCASE on melanogenesis has not been explored. In the cell viability assay, TCASE did not show a cytotoxic effect at a dose of 65 microM for 48 h in B16, HaCaT and Hs68 cells. TCASE considerably inhibits melanin synthesis, and reduces intracellular cyclic adenosine monophosphate (cAMP) levels, tyrosinase activity and L-3-(3,4-dihydroxyphenyl)-alanine (DOPA) oxidase activity in a concentration-dependent manner in the presence of alpha-melanocyte-stimulating hormone (alpha-MSH) in B16 cells, and the inhibition efficiency of TCASE exceeds that of ascorbic acid and arbutin. TCASE reduces melanocortin-1 receptor (MC1R), microphthalmia transcription factor (MITF), tyrosinase, tyrosinase-related protein-2 (TRP-2) and TRP-1 mRNA and protein levels in B16 cells. Based on the findings, TCASE is posited to inhibit melanogenesis signaling while suppressing cAMP levels and, subsequently, MC1R, MITF, tyrosinase, TRP-2 and TRP-1 down-regulation, resulting in the suppression of tyrosinase activity, DOPA oxidase activity and melanin synthesis.
Genes and enzymes involved in caffeic acid biosynthesis in the actinomycete Saccharothrix espanaensis.[Pubmed:16547054]
J Bacteriol. 2006 Apr;188(7):2666-73.
The saccharomicins A and B, produced by the actinomycete Saccharothrix espanaensis, are oligosaccharide antibiotics. They consist of 17 monosaccharide units and the unique aglycon N-(m,p-dihydroxycinnamoyl)taurine. To investigate candidate genes responsible for the formation of trans-m,p-dihydroxycinnamic acid (caffeic acid) as part of the saccharomicin aglycon, gene expression experiments were carried out in Streptomyces fradiae XKS. It is shown that the biosynthetic pathway for Trans-caffeic acid proceeds from L-tyrosine via trans-p-coumaric acid directly to Trans-caffeic acid, since heterologous expression of sam8, encoding a tyrosine ammonia-lyase, led to the production of trans-p-hydroxycinnamic acid (coumaric acid), and coexpression of sam8 and sam5, the latter encoding a 4-coumarate 3-hydroxylase, led to the production of trans-m,p-dihydroxycinnamic acid. This is not in accordance with the general phenylpropanoid pathway in plants, where trans-p-coumaric acid is first activated before the 3-hydroxylation of its ring takes place.
