Abstract
A novel cytochrome P450 from Tripterygium wilfordii, CYP81AM1, specifically catalyses the C-15 hydroxylation of dehydroabietic acid. This is the first CYP450 to be found in plants with this function. Cytochrome P450 oxygenases (CYPs) play an important role in the post-modification in biosynthesis of plant bioactive terpenoids. Here, we found that CYP81AM1 can catalyze the formation of 15-hydroxydehydroabietic acid by in vitro enzymatic reactions and in vivo yeast feeding assays. This is the first study to show that CYP81 family enzymes are involved in the hydroxylation of abietane diterpenoids. At the same time, we found that CYP81AM1 could not catalyse abietatriene and dehydroabietinol, suggesting that the occurrence of the reaction may be related to the carboxyl group. Through molecular docking and site mutations, it was found that some amino acid sites (F104, K107) near the carboxyl group had an important effect on enzyme activity, also suggesting that the carboxyl group played an important role in the occurrence of the reaction.

Structurally diversified ent-kaurane and abietane diterpenoids from the stems of Tripterygium wilfordii and their anti-inflammatory activity. Bioorg Chem 2021; 115:105178. [PMID: 34303897 DOI: 10.1016/j.bioorg.2021.105178] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Revised: 06/30/2021] [Accepted: 07/12/2021] [Indexed: 12/20/2022]
Abstract
Four undescribed ent-kaurane diterpenoids, wilkaunoids A - D (1-4), and three undescribed abietane diterpenoids, wilabinoids A - C (13-15), along with thirteen known ones (5-12 and 16-20), were isolated from Tripterygium wilfordii. Their structures were elucidated by extensive spectroscopic methods, electroniccirculardichroism calculation, and X-ray diffraction analysis. Compounds 1 and 2 were a pair of C-19 epimers of ent-kaurane diterpenoids, featuring a rare 19,20-epoxy-19,20-dimethoxy-kaurane fragment. Compound 3 possessed a rare naturally occurring 1,3-dioxacyclohexane moiety. Compounds 13 and 15 represented the first example of abietane diterpenoids with an isovalerate substitution from the genus of Tripterygium. The possible biosynthetic pathways of 1-3 were postulated. The effect of 1-20 on nitric oxide production was examined in lipopolysaccharide-stimulated RAW 264.7 cells. Abietane diterpenoid quinones 7-13 (IC50: 1.9-10.2 μM) exhibited the significant activity to inhibit nitric oxide production versus positive control (NG-monomethyl-l-arginine acetate salt, IC50 = 24.9 μM). The structure activity relationship of 7-13 in inhibiting nitric oxide production was then discussed. The most potent 7 and 8 were found to significantly suppress the expression of cyclooxygenase-2 and inducible nitric oxide synthase proteins, showing a good anti-inflammatory potential. The findings provided some valuable insights for the discovery and structural modification of abietane diterpenoids towards anti-inflammatory lead compounds.

The isolation, structure and fragmentation characteristics of natural truxillic and truxinic acid derivatives in Abrus mollis leaves. PHYTOCHEMISTRY 2021; 181:112572. [PMID: 33166750 DOI: 10.1016/j.phytochem.2020.112572] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/26/2020] [Revised: 10/20/2020] [Accepted: 10/22/2020] [Indexed: 06/11/2023]
Abstract
Five undescribed compounds were separated from Abrus mollis leaves, including two truxillate forms (abrusamide D, H) and three truxinate forms (abrusamide E, F, G). The absolute configuration of abrusamide D was determined by X-ray crystallography. Abrusamide A was reassessed and corrected to be β-truxinate configuration rather than α-form. LC-MS/MS and CD spectroscopy were applied to determine and analyze ten compounds, including four truxillate forms (abrusamide B ~ D and H), four truxinate forms (abrusamide E ~ G and A), and two precursors [(E)-N-(4-hydroxycinnamoyl) tyrosine, (Z)-N-(4-hydroxycinnamoyl) tyrosine]. It showed that the fragmentation pattern of truxillate was symmetric, while that of truxinate was asymmetric and irregular. The CD Cotton effect was related to cyclobutane configuration. These findings provided strong evidence for the cyclobutane dimers to discriminate their configuration. In addition, the bioactivity assay showed that the compounds had low toxicity and anti-inflammatory effect.

Abstract
Four new 5,6,7,8-tetrahydro-2-(2-phenylethyl)chromones, aqulisinone A (1), (5S, 6R,7S,8S)-8-chloro-5,6,7-trihydroxy-2-[2-(4'-methoxyphenylethyl)]-5,6,7,8-tetrahydrochromone (2), (5S,6R,7S,8S)-8-chloro-5,6,7-trihydroxy-2-(2-phenylethyl)-5,6,7,8-tetrahydrochromone (3), (5S*,6R*,7R*,8S*)-8-chloro-5-ethoxy-6,7-dihydroxy-2-[2-(3'-hydroxy-4'-methoxy-phenylethyl)-5,6,7,8-tetrahydrochromone (4), and seven known analogues (5-11) were isolated from agarwood produced of Aquilaria sinensis. Among the new compounds, 4 is an artifact. The structures were elucidated using spectroscopic methods and by comparison with published NMR spectroscopic data. The absolute configurations of 1-3 were defined based on single-crystal X-ray diffraction and electronic circular dichroism (ECD) data. Compound 1 features a (5,5'')-carbon-carbon bond linkage connecting two 2-(2-phenylethyl)chromone monomeric units. All the new compounds were evaluated for their anti-inflammatory activities by inhibiting the lipopolysaccharide (LPS)-induced nitric oxide (NO) release in RAW264.7 cells, 2 with an IC50 value of 3.46 μM.

Abstract
Nine new gastrodin derivatives, including seven p-hydroxybenzyl-modified gastrodin ethers (1-7), 6'-O-acetylgastrodin (8), and 4-[α-D-glucopyranosyl-(1 →6)-β-D-glucopyranosyloxy]benzyl alcohol (9), together with seven known derivatives, were isolated from an aqueous extract of Gastrodia elata ("tian ma") rhizomes. Their structures were determined by spectroscopic and chemical methods as well as single crystal X-ray diffraction. Compounds 1-4, 7, 10, and 11 were also isolated from a reaction mixture by refluxing gastrodin and p-hydroxybenzyl alcohol in H2O. As both gastrodin and p-hydroxybenzyl alcohol exist in the plant, the reaction results provide evidence for the production and increase/decrease of potential effective/toxic components when "tian ma" is decocted solely or together with ingredients in Chinese traditional medicine formulations, though the isolates were inactive in the preliminarily cell-based assays at concentrations of 10 μM. Moreover, using ultra-performance liquid chromatography high-resolution electrospray ionization mass spectrometry (UPLC-HRESIMS), 4, 7, 10, and 11, as well as component variations, were detectable in the freshly prepared extracts of different types of samples, including the freeze-dried fresh G. elata rhizomes.
