Garciyunnanones A-R: Caged polycyclic polyprenylated acylphloroglucinols decorated with a lavandulyl substituent from Garcinia yunnanensis. PHYTOCHEMISTRY 2024; 224:114167. [PMID: 38810816 DOI: 10.1016/j.phytochem.2024.114167] [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: 01/27/2024] [Revised: 05/25/2024] [Accepted: 05/26/2024] [Indexed: 05/31/2024]
Abstract
Garciyunnanones A-R (1-18), eighteen undescribed caged polycyclic polyprenylated acylphloroglucinols, two undescribed biogenetic congeners (19-20), and nineteen known analogues (21-39), were isolated from the stem barks of Garcinia yunnanensis Hu. All of these isolates are decorated with a C-5 lavandulyl substituent. Their structures and absolute configurations were confirmed by HRESIMS, 1D & 2D NMR spectroscopic analysis, quantum chemical calculations of electronic circular dichroism data, and single-crystal X-ray diffraction analysis. The X-ray crystallographic data of ten isolated caged compounds ascertained the absolute configuration of C-23 in the lavandulyl as S. The cytotoxicity on three cancer cell lines and the anti-nonalcoholic steatohepatitis activity of the isolates were tested. In a free fatty acid-induced L02 cell model, compounds 33 and 39 decreased intracellular lipid accumulation significantly.

Abstract
Six scalemic mixtures of previously undescribed diacetylenic spiroacetal enol ethers (DSEEs) and six scalemic mixtures of known DSEEs were isolated from the flowers of Tanacetum tatsienense. Except for E-epidendranthemenol, Z-O-acetyl-epi dendranthemenol, and Z-O-isovaleryl-epidendranthemenol, the remaining scalemic mixtures of DSEEs were resolved by chiral HPLC, and their structures were determined through an analysis of HR-ESI-MS and NMR data. The absolute configurations of seven pairs of enantiomers and one pair of epimers were determined by comparing the experimental and calculated electronic circular dichroism (ECD) spectra. In addition, the inhibitory effects of all of the DSEEs on nitric oxide (NO) production were evaluated in LPS-stimulated RAW264.7 cells. The results showed that (+)-tatsienenol B had a weak inhibitory effect on NO production. The IC50 value of the compound was 19.78 ± 0.78 μM. This study is the first to report that DSEEs are isolable from plants as scalemic mixtures. Moreover, this study is the first to determine the absolute configurations of DSEEs by chiral resolution and ECD calculations.

Abstract
Eleven new polycyclic polyprenylated acylphloroglucinols (PPAPs, 1-11) and three new monocyclic polyprenylated acylphloroglucinols (MPAPs, 12-14), together with ten known analogues were isolated from the fruits of Garcinia multiflora. These PPAPs belong to three types including the bicyclic polyprenylated acylphloroglucinols (BPAPs), the caged PPAPs, and the complicated PPAPs. Their structures and absolute configurations were determined through HRESIMS, NMR spectroscopy data, electronic circular dichroism (ECD) calculations, and gauge-independent atomic orbital (GIAO) NMR calculations with DP4+ analyses. Moreover, compounds 2 and 7 exhibited moderate cytotoxicity against three human cancer lines (MCF-7, T98, and HepG2) with IC50 values ranging from 9.81 ± 1.56 to 17.00 ± 2.75 μM.

Abstract
Sixteen lignans with diverse carbon skeletons, including tetrahydrofuran lignans (1, 13-18), 7,9'-dinorlignan (2), dibenzylbutane lignans (9-10), aryl tetrahydronaphthalene lignans (11-12), dihydrobenzofuran neolignans (19-20), 8-O-4' neolignans (21-22), and six clerodane diterpenoid glucosides (3-8) were isolated from the 70% ethanolic extract of the stems of Tinospora sinensis (Lour.) Merr. Their structures were established by spectroscopic analyses and chemical methods. Among all these isolates, compounds 1-2 and 3-4 were determined as previously undescribed lignans and clerodane diterpenoids respectively, and compounds 9-13 and 17-22 were discovered from T. sinensis for the first time. In addition, it was the first time to report three types of lignans including 7,9'-dinorlignan, dihydrobenzofuran neolignan and 8-O-4' neolignan from T. sinensis. The biological activities of all isolated compounds were assessed in terms of their nitric oxide production inhibitory activity in LPS stimulated RAW264.7 cells. The results showed that compound 20 exhibited a mild NO production inhibitory effect with an IC50 value of 17.43 ± 2.06 μM.

Abstract
Glycosmis pentaphylla (Retz.) DC (Rutaceae) has been traditionally considered as anti-cancer and anti-inflammatory medicine. However, active compounds of sulphur-containing amides remain largely unknown. In the present work, eighteen previously undescribed sulphur-containing amides (1-18) and three known analogues (19-21) were isolated from the leaves of G. pentaphylla. Their structures were elucidated by NMR spectroscopy and mass spectrometry. All isolated prenylated sulphur-containing amides were evaluated for their anti-inflammatory properties together with antiproliferative activities in vivo. Prenylated sulphur-containing amides exhibited significant inhibitory effects against nitric oxide (NO) production stimulated by lipopolysaccharide in mouse macrophage RAW 264.7 cells with the IC50 values ranging from 0.16 ± 0.10 to 16.74 ± 2.81 μM. Meanwhile, sulphur-containing amides also exhibited considerable antiproliferative activities against HepG2 cell line with IC50 values ranging from 7.47 ± 0.91 to 16.23 ± 0.80 μM. These findings enrich and improve the research on the structural diversity and biological activity of sulphur-containing amides and provide phytochemical and pharmacological evidence for the further development and utilization of the leaves of G. pentaphylla in pharmaceutical industry.

Abstract
Six new ent-kaurane diterpenoids, isodonrubescins A-F (1-6), together with twenty-five known ent-kaurane diterpenoids (7-31), a known ent-atisane diterpenoid (32), and two known ent-abietane diterpenoids (33-34), were isolated from Isodon rubescens. Their structures were established by means of extensive MS and NMR data analysis. Among the all isolates, compound 7 was found in a natural product for the first time, and ent-atisane diterpenoid was discovered from I. rubescens in Hubei Province, P. R. China for the first time. Furthermore, all the isolated compounds were tested for their NO production inhibitory activity in LPS stimulated RAW264.7 cells. Compounds 7-9, 12, 13, 16, and 17 displayed NO production inhibitory activities with IC50 values ranging from 1.36 to 18.25 μM, respectively.
