PHYTOCHEMISTRY 2024; 224:114145. [PMID: 38759829 DOI: 10.1016/j.phytochem.2024.114145] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/24/2024] [Revised: 05/14/2024] [Accepted: 05/14/2024] [Indexed: 05/19/2024]
Abstract
Eleven previously undescribed abietane-type diterpenoids, named caryopincanoids A-K (1-11), together with five known compounds, were isolated from the EtOH extract of the aerial parts of Caryopteris incana (Thunb.) Miq. Their structures were elucidated on the basis of comprehensive spectroscopic data, NMR calculations, and ECD calculations. The inhibitory activities of all compounds against HIF-2α gene expression in 786-O cells were tested by luciferase assay. Compounds 7, 9, 15, and 16 showed significant inhibitory effects with IC50 values ranging from 12.73 to 23.80 μM. The preliminary structure-activity relationship of these compounds was also discussed.

Effects of bioconversion by Battus polydamas on the chemical composition of Aristolochia spp. and evaluation of antimicrobial activity and biocompatibility. Fitoterapia 2024; 175:105949. [PMID: 38583636 DOI: 10.1016/j.fitote.2024.105949] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Revised: 03/13/2024] [Accepted: 04/04/2024] [Indexed: 04/09/2024]
Abstract
Aristolochia plants are emblematic from an ethnopharmacological viewpoint and are know to possess numerous biological properties, including antiseptic. However, the medicinal potential of these species is debatable because of their representative chemical constituents, aristolochic acids (AAs) and aristolactams (ALs), which are associated, for instance, with nephropathy and cancer. These contrasting issues have stimulated the development of approaches intended to detoxification of aristoloquiaceous biomasses, among which is included the bioconversion method using larvae of the specialist phytophagous insect Battus polydamas, previously shown to be viable for chemical diversification and to reduce toxicity. Thus, eleven Aristolochia spp. were bioconverted, and the antimicrobial activities of the plant methanolic extracts and its respective bioconversion products were evaluated. The best results were found for Aristolochia esperanzae, Aristolochia gibertii, and Aristolochia ringens against Bacillus cereus, with MIC ranging from 7.8 to 31.25 μg/mL. These three species were selected for chemical, antioxidant, cytotoxic, hemolytic, and mutagenic analyses. Chemical analysis revealed 65 compounds, 21 of them possible bioconversion products. The extracts showed potential to inhibit the formation and degradation of B. cereus biofilms. Extracts of A. gibertii and its bioconverted biomass showed antioxidant activity comparable to dibutylhydroxytoluene (BHT) standard. Bioconversion decreased the hemolytic activity of A. esperanzae and the cytotoxicities of A. esperanzae and A. gibertii. None of the extracts was found to be mutagenic. The bioactivities of the fecal extracts were maintained, and biocompatibility was improved. Therefore, the results obtained in this study reveal positive expectations about the natural detoxification process of the Aristolochia species.

Abstract
Callicarpa rubella is a characteristic folk herb in the genus Callicarpa, and has abundant ethnobotanical usage as indigenous medicine in Lingnan area of P. R. China. However, the phytochemical and pharmacological properties of C. rubella was rarely investigated. Now, three new diterpenoids, named rubellapene A-C (1-3), along with five known analogues (4-8), were isolated from C. rubella. Their structures were determined by spectroscopic methods, quantum chemical electronic circular dichroism calculations and single-crystal X-ray diffraction analysis. Notably, the norditerpenoids C18 of clerodane type (rubellapene B) was rarely found in the genus Callicarpa. The liver protective effects of all of the isolates (1-8) were evaluated by the changes of cell viability and transaminase content of AST and ALT in H2O2-induced BRL cells. Compound 1, 3-8 exhibited that potent liver protective effects at different levels.

Abstract
Three undescribed dimeric pyridine-containing alkaloids, caryopterisines C - E, and four unreported cyclopenta[c]pyridine-derived alkaloids, caryopterisines F - I, were identified from Caryopteris glutinosa Rehder (Lamiaceae), together with two known monoterpene alkaloids. Caryopterisine C, featuring with an unprecedented 6/5/6/6/5 pentacyclic rings scaffold, may biosynthetically stem from a Diels-Alder reaction of two cyclopenta[c]pyridine-containing monomers and a following aromatization rearrangement reaction. Caryopterisines D and E, possessing an unprecedented 6/6/6/6/5 fused rings framework, may originate from a same Diels-Alder reaction of two monomers and subsequent aromatization arrangement, Baeyer-Villiger oxidation, and a set of tailoring reactions. Caryopterisine C showed strong inhibition on collagen accumulation in NIH3T3 cells (IC50 = 14.26 ± 1.46 μM). Caryopterisines G and I reduce collagen accumulation with IC50 values 88.91 ± 0.95 μM and 33.09 ± 1.38 μM, respectively. The Western blotting of the transforming growth factor-β-activated signaling pathways revealed that caryopterisine C inhibits collagen expression and accumulation via suppression of the phosphorylation of ERK1/2, P38, and SMAD2/3. The present works indicate caryopterisine C is a potential lead compound for the development of antifibrotic drugs.

Abstract
(±)-Caryopterisines A (1) and B (2) featuring an unprecedented 6/5/5/5/6 pentacyclic rings system were isolated from Caryopteris glutinosa. The structures were determined by spectroscopic and X-ray crystallographic data analyses as well as theoretical calculations. Chiral HPLC resolution of both racemic 1 and 2 afforded their corresponding enantiotropic enantiomers. A plausible biogenesis for 1 and 2 may be originated from Diels-Alder reaction between pyridine-containing oxerine derivatives. The enantiotropic conversion mechanism of the enantiomers was demonstrated by H-D exchange and 18O incorporation studies. Compounds 1 and 2 showed moderate inhibition of estrogen E2 biosynthesis in human ovarian granulosa-like KGN cells. These two alkaloids reduced kynurenine biosynthesis at moderate level via inhibition of indoleamine 2,3-dioxygenase. Alkaloid 2 exhibited moderate inhibition of the release of interleukin-1β.

Abstract
Seven new (1-7) and 11 known diterpenoids were isolated and identified from Caryopteris aureoglandulosa. These diterpenoids were structurally determined by HRESIMS and NMR spectroscopic analyses, single-crystal X-ray diffraction, and ECD data. Structurally, aureoglandulosin A (1) is a highly oxygenated abietane diterpenoid with an unprecedented 7/6/6/5-ring system. Aureoglandulosins B (2) and C (3) represent naturally occurring new diterpenoids with an unusual 6/6/6/5-ring system. Additionally, the configurations of two known abietane diterpenoids 11 and 12 were determined by X-ray crystallographic data analysis for the first time. A plausible biosynthetic pathway for compounds 1-3 is proposed. The cytotoxicity of all isolates was evaluated, and compounds 1 and 11 exhibited significant cytotoxic activity against some cell lines with IC50 values in the range 1.6-8.2 μM.

Abstract
Viburnumfocesides A - D, four undescribed 1-O-isovaleroylated iridoid 11-O-allosides modified with (Z / E)-p-coumaric acid, were isolated from the aqueous EtOH extract of the twigs of Viburnum foetidum var. ceanothoides, together with seven known natural products. Their structures were identified on the basis of the spectroscopic data interpretation and chemical derivation studies. Cell-based estrogen biosynthesis assays indicated that viburnumfoceside D (4), (2S,3R)-2,3-dihydro-3-hydroxymethyl-7-methoxy-2-(4-hydroxy-3-methoxyphenyl)-5-benzofuranpropanol-3a-O-α-L-rhamnopyranoside (8), and (-)-eriodictyol (11) inhibit estrogen biosynthesis with IC50 values of 5.8, 1.5, and 1.1 μM, respectively, in human ovarian granulosa-like KGN cells via decreasing the expression level of aromatase.
