The melanin synthesis inhibition and radical scavenging activities of compounds isolated from the aerial part of Lespedeza cyrtobotrya.[Pubmed:20622497]
J Microbiol Biotechnol. 2010 Jun;20(6):988-94.
The EtOAc fraction of Lespedeza cyrtobotrya showed mushroom tyrosinase inhibitory and radical scavenging activity. Four active compounds were isolated based on LH-20 chromatography and HPLC, and the structures were elucidated on the basis of their LC-MS and NMR spectral data, as 2-(2,4-Dihydroxyphenyl)-6-hydroxybenzofuran (1), eriodictyol-7-O-glucopyranoside (2), Haginin A (3), and dalbergioidin (4), respectively. 2-(2,4-Dihydroxyphenyl)-6-hydroxybenzofuran (1) showed mushroom tyrosinase inhibitory activity with an IC50 value of 5.2 micronM and acted as a competitive inhibitor. Furthermore, 37.3 micronM of compound 1 reduced 50 % of the melanin content on a human melanoma (MNT-1) cells. The radical scavenging activity of 2-(2,4-dihydroxyphenyl)-6-hydroxybenzofuran (1), eriodictyol-7-O-glucopyranoside (2), Haginin A (3), and dalbergioidin (4) was shown with IC50 values of 11.0, 24.5, 9.0 and 36.5 micronM in an ABTS system and with IC50 values of 42.7, 36.0, 37.7 and 61.7 micronM in a DPPH system, respectively. The mushroom tyrosinase inhibitory activity of EtOAc fraction of Lespedeza cyrtobotrya was contributed by compound 1, 3 and 4, and radical scavenging activity of it was contributed by compound 1-4.
Downregulation of melanin synthesis by haginin A and its application to in vivo lightening model.[Pubmed:18037902]
J Invest Dermatol. 2008 May;128(5):1227-35.
Haginin A, an isoflav-3-ens isolated from the branch of Lespedeza cyrtobotrya, is almost unknown. Here, we report that Haginin A exhibits a strong hypopigmentary effect in Melan-a cells and significantly inhibits melanin synthesis. Haginin A shows potent inhibitory effects with an IC(50) (half-maximal inhibitory concentration) value of 5.0 microM on mushroom tyrosinase activity, and functioned as a noncompetitive inhibitor. Also, Haginin A decreased microphthalmia-associated transcription factor (MITF), tyrosinase, and tyrosinase-related protein-1 (TRP-1) protein production. To identify the signaling pathway of Haginin A, the ability of Haginin A to influence extracellular signal-regulated protein kinase (ERK) and Akt/protein kinase B (PKB) activation was investigated. Apparently, Haginin A induced ERK and Akt/PKB in a dose-dependent manner. In addition, the specific inhibition of the ERK and the Akt/PKB signaling pathways by PD98059 and LY294002, respectively, increased melanin synthesis. Furthermore, Haginin A decreased UV-induced skin pigmentation in brown guinea-pigs. Also, Haginin A presented remarkable inhibition on the body pigmentation in the zebrafish model system and decreased tyrosinase activity. Together, Haginin A is an effective inhibitor of hyperpigmentation caused by UV irradiation or by pigmented skin disorders through downregulation via ERK and Akt/PKB activation, MITF, and also by the subsequent downregulation of tyrosinase and TRP-1 production.
