Melanogenesis-Inhibitory and Antioxidant Activities of Phenolics from Periploca forrestii.[Pubmed:28488417]
Chem Biodivers. 2017 Aug;14(8).
Two new tetrahydrofuran-type lignans, (-)-gentioluteol 9-O-beta-d-glucopyranoside (1), (-)-Berchemol 9-O-beta-d-apiofuranosyl-(1-->6)-O-beta-d-glucopyranoside (2), along with sixteen known compounds 3 - 18 were isolated from the 95% EtOH extract of the stems of Periploca forrestii. The structures of the new tetrahydrofuran-type lignans were determined by HR-ESI-MS and various NMR techniques in combination with CD method. Then, their antioxidant abilities were evaluated by 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activity, and ferric-reducing antioxidant power (FRAP) assays. Meanwhile, a similar trend was obtained in tripartite antioxidant assays, which compounds 7 - 9 and 11 exhibited potent abilities. Subsequently, the evaluation of all compounds against the alpha-melanocyte-stimulating hormone (alpha-MSH) induced melanogenesis on the B16F10 cell line, compounds 5 - 11, 15, and 16 exhibited inhibitory effects with no or weak toxicity at low concentration. Of these, compound 8 exhibited the strongest inhibition melanogenesis ability. Furthermore, Western blot analysis suggested that compound 8 could inhibit melanogenesis by suppressing the protein expression of microphthalmia-associated transcription factor (MITF) and tyrosinase.
[Anti-tumor metastatic constituents from Rhodiola wallichiana].[Pubmed:26080555]
Zhongguo Zhong Yao Za Zhi. 2015 Jan;40(2):258-63.
To study the anti-tumor metastatic constituents in Rhodiola wallichiana (HK) S H Fu var Cholaensis (Praeg) S H Fu, chemical constituents were isolated and purified by repeated column chromatography (silica gel, Toyopearl HW-40C and preparative HPLC). Their structures were elucidated on the basis of spectral data analysis. The anti-tumor metastasis assay was applied to evaluate the activities of the isolated compounds. Ten compounds (1-10) were isolated and their structures were identified by comparison of their spectral data with literature as follows: syringic acid (1), salidroside (2), tyrosol (3), scaphopetalone (4), Berchemol (5), 2,6-dimethoxyacetophenone (6), rhobupcyanoside A (7), miyaginin (8), chavicol-4-O-beta-D-apiofuranosyl-(1 --> 6)-O-beta-D-glucopyranoside (9), eugenyol-O-beta-D-apiofuranosyl-(1 --> 6)-O-beta-D-glucopyranoside (10). Compounds 4-6 and 8-10, were isolated from this genus for the first time, while compound 7 was isolated from this plant for the first time. Compounds 2, 6-8 showed positive anti-tumor metastatic activities, and compounds 2 and 8 showed significant anti-tumor metastatic activities.
A new neolignan glycoside from the leaves of Acer truncatum.[Pubmed:18007405]
Molecules. 2006 Dec 21;11(12):1009-14.
A new neolignan glycoside, (7R,8R)-7,8-dihydro-9'-hydroxyl-3'-methoxyl- 8-hydroxymethyl-7-(4-hydroxy-3-methoxyphenyl)-1'-benzofuranpropanol 9'-O-beta-D- glucopyranoside (1) was isolated from the leaves of Acer truncatum along with (7R,8R)-7,8-dihydro-9'-hydroxyl-3'-methoxyl-8-hydroxymethyl-7-(4-O-alpha-L-rhamno- pyranosyloxy-3-methoxyphenyl)-1'-benzofuranpropanol (2), schizandriside (3), lyoniresinol (4), Berchemol (5), (-)-pinoresinol-4-O-beta-D-glucopyranoside (6), hecogenin (7), chlorogenic acid (8) and neochlorogenic acid (9). Their structures were elucidated on the basis of extensive spectroscopic data. The absolute configuration of compounds 1 was established by its CD spectrum. The antibacterial activities of compounds 1-7 were evaluated.
Prostaglandin inhibitory and antioxidant components of Cistus laurifolius, a Turkish medicinal plant.[Pubmed:16814498]
J Ethnopharmacol. 2006 Dec 6;108(3):371-8.
As Cistus laurifolius has been used traditionally to treat inflammatory and rheumatic disorders, its leaves were tested for prostaglandin (PG) inhibitory and antioxidant activities. The leaf extract showed both activities, i.e., inhibitory effect at 300 microg/ml on PGE1- and E2-induced contractions in guinea pig ileum and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging effect. The separation guided by the activities shown by these dual assays provided sixteen compounds, 1-16. Known compounds 1-12 and 15 were identified as 3-O-methyl quercetin (1), 3,7-O-dimethyl quercetin (2), genkwanin (3), 3,7-O-dimethyl kaempferol (4), 3,4'-O-dimethyl quercetin (5), apigenin (6), 3,4'-O-dimethyl kaempferol (7), ellagic acid (8), beta-sitosterol-3-O-beta-glucoside (9), quercetin 3-O-alpha-rhamnoside (10), 5-O-p-coumaroyl quinic acid methyl ester (11), 1-(4-hydroxy-3-methoxyphenyl)-2-[4-(3-alpha-l-rhamnopyranoxypropyl)-2-methoxyphenoxy]-1,3-propanediol (12) and 2,3-dihydro-2-(4'-alpha-l-rhamnopyranosyloxy-3'-methoxyphenyl)-3-hydroxymethyl-7-methoxy-5-benzofuranpropanol (15). New lignan glycosides 13 and 14 were determined to be olivil 9-O-beta-D-xyloside and Berchemol 9-O-rhamnoside, respectively. Compound 16 was isolated as a 2:1 mixture of two diastereomers, the major one of which was determined to be (7S,8R)-dihydrodehydrodiconiferyl alcohol 9'-O-alpha-L-rhamnoside. The structures were determined by detailed 2D NMR analysis together with NOEDF and CD. PG inhibitory effect was observed in 1, 5, 10, 12 and 16 at 30 microg/ml and antioxidant activity, in 1, 2, 8, 10, 12-14 and 16.
Lignans isolated from valerian: identification and characterization of a new olivil derivative with partial agonistic activity at A(1) adenosine receptors.[Pubmed:12398547]
J Nat Prod. 2002 Oct;65(10):1479-85.
A methanolic extract of the roots of Valeriana officinalis (valerian) was investigated for its lignan content. In addition to the lignans 8'-hydroxypinoresinol (1) and pinoresinol-4-O-beta-D-glucoside (2), which had already been isolated from valerian in an earlier study, the 7,9'-monoepoxylignans massoniresinol-4'-O-beta-D-glucoside (3), 4'-O-beta-D-glucosyl-9-O-(6' '-deoxysaccharosyl)olivil (4), and Berchemol-4'-O-beta-D-glucoside (5) and the 7,9':7',9-diepoxylignans pinoresinol-4,4'-di-beta-O-D-glucoside (6), 8-hydroxypinoresinol-4'-O-beta-D-glucoside (7), and 8'-hydroxypinoresinol-4'-O-beta-D-glucoside (8) were identified. While lignans 3, 6, 7, and 8 had already been isolated from other plants, lignans 4 and 5 are new natural products. The lignans were investigated in radioligand binding assays at various receptors of the central nervous system, including GABA(A), benzodiazepine, 5-HT(1A), and adenosine A(1) and A(2A) receptors, to investigate their potential contribution to the pharmacological activity of valerian. The novel olivil derivative 4 proved to be a partial agonist at rat and human A(1) adenosine receptors exhibiting A(1) affinity and activity in low micromolar to submicromolar concentrations. Lignan 4 is the first nonnucleoside adenosine receptor agonist not structurally related to adenosine.
