Trimeric and Tetrameric A-Type Procyanidins from Peanut Skins.[Pubmed:28231711]
J Nat Prod. 2017 Feb 24;80(2):415-426.
Peanut skins are a rich source of oligomeric and polymeric procyanidins. The oligomeric fractions are dominated by dimers, trimers, and tetramers. A multistep chromatographic fractionation led to the isolation of four new A-type procyanidins of tri- and tetrameric structures. The structures of the new trimers were defined by NMR, electronic circular dichroism, and MS data as epicatechin-(4beta-->8,2beta-->O-->7)-epicatechin-(4beta-->8,2beta-->O-->7)-catec hin, Peanut procyanidin B (3), and epicatechin-(4beta-->8,2beta-->O-->7)-epicatechin-(4beta-->6)-catechin, peanut procyanidin C (4). The new tetramers were defined as epicatechin-(4beta-->8,2beta-->O-->7)-epicatechin-(4beta-->6)-epicatechin-(4beta- ->8,2beta-->O-->7)-catechin, peanut procyanidin E (1), and epicatechin-(4beta-->8,2beta-->O-->7)-epicatechin-(4beta-->6)-epicatechin-(4beta- ->8,2beta-->O-->7)-epicatechin, peanut procyanidin F (2). In addition, both A-type dimers A1, epicatechin-(4beta-->8,2beta-->O-->7)-catechin, and A2, epicatechin-(4beta-->8,2beta-->O-->7)-epicatechin, as well as two known peanut trimers, ent-epicatechin-(4beta-->6)-epicatechin-(4beta-->8,2beta-->O-->7)-catechin, peanut procyanidin A (5), and epicatechin-(4beta-->8)-epicatechin-(4beta-->8,2beta-->O-->7)-catechin, peanut procyanidin D (6), were also isolated. Dimer A1, the four trimers, and two tetramers were evaluated for anti-inflammatory activity in an in vitro assay, in which LPS-stimulated macrophages were responding with secretion of TNF-alpha, a pro-inflammatory cytokine. Tetramer F (2) was the most potent, suppressing TNF-alpha secretion to 82% at 8.7 muM (10 mug/mL), while tetramer E (1) at the same concentrations caused a 4% suppression. The results of the TNF-alpha secretion inhibition indicate that small structural differences, as in peanut procyanidin tetramers E and F, can be strongly differentiated in biological systems.
