[PMID: 35889467 PMCID: PMC9324186 DOI: 10.3390/molecules27144596] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2022] [Revised: 07/11/2022] [Accepted: 07/15/2022] [Indexed: 02/04/2023] Open
Abstract
From the dried vines of Aspidopterys obcordata Hemsl, five new polyoxypregnane glycosides, named obcordatas J–N (1–5), were obtained. Their structures were fully elucidated and characterized by HRESIMS and extensive spectroscopic data. In addition, all of the new compounds were screened for their antinephrolithiasis activity in vitro. The results showed that compounds 1–3 have prominent protective effects on calcium oxalate crystal-induced human kidney 2 (HK-2) cells, with EC50 values ranging from 6.72 to 14.00 μM, which is consistent with the application value of A. obcordata in folk medicine for kidney stones.

[PMID: 35071186 PMCID: PMC8766633 DOI: 10.3389/fchem.2021.799911] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2021] [Accepted: 12/06/2021] [Indexed: 12/22/2022] Open
Abstract
The bioassay-guided phytochemical study of an ethnic medicinal plant Aspidopterys obcorda ta Hemsl. var. obcordata results in the isolation of eight new polyoxypregnane derivatives, named aspidatasides A–H (1–8), along with ten known analogs (9–18). The series polyoxypregnane derivatives were screened for their cytoxic activity against HL-60 cells, and compound 2 showed the highest potency with an IC50 8.03 μM. Preliminary structure–activity relationship studies displayed that the sugar chain and double bond could notably impact their biological activity.

Bailly C. Anticancer properties of caudatin and related C-21 steroidal glycosides from Cynanchum plants. Steroids 2021; 172:108855. [PMID: 33945800 DOI: 10.1016/j.steroids.2021.108855] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2021] [Revised: 03/29/2021] [Accepted: 04/22/2021] [Indexed: 12/12/2022]
Abstract
Numerous C-21 steroidal glycosides have been isolated from Cynanchum plants. Many of them derive from the aglycone caudatin (CDT) which includes a tetracyclic deacylmetaplexigenin unit and an ikemaoyl ester side chain. CDT can be found in diverse traditional medicines, such as Baishouwu radix used to treat gastro-intestinal disorders. The compound has revealed marked anticancer properties, reviewed here. CDT and its mono-glycoside analogue CDMC display antiproliferative activities against different cancer cell lines in vitro and have revealed significant anticancer effects in tumor xenograft models in vivo. Their mechanism of action is multifactorial, implicating several signaling pathways (Wnt/GSK3/β-catenin, TRAIL/DR5/ER and TNFAIP1/NFκB) which contribute to the antiproliferative, antiangiogenic, antimetastatic and proapoptotic effects of the natural products. CDT also modulates DNA replication, is antioxidant and targets some cancer stem cells. CDT and CDMC are interesting anticancer products, while other CDT glycoside derivatives display antiviral and antifungal activities. Altogether, the present review provides a survey of the pharmacological profiles of CDT and derivatives. The lack of knowledge about the molecular targets of CDT currently limits drug development but the natural product, orally active, warrants further pharmacology and toxicology studies.

Abstract
By HPLC-MSn and HRMS analyses, the structures of 52 polyoxypregnane glycosides were rapidly inferred from Dregea sinensis Hemsl on the basis of their sodium-cationized molecules [M + Na]+ and predominant diagnostic ions resulting from the saccharic chain on C3 and the neutral loss of substituent on C11 and C12. Compounds 1 and 7 significantly inhibited LPS-stimulated splenocyte proliferation in vitro.[Formula: see text].

Abstract
Two new polyoxy steroidal glycosides, named as 11- O-α-acetyl-12-O-β-tigloyl- 3β,14β-dihydroxy-pregn-5-en-20-one-3-O-β-D-oleadropyranosyl-(1→4)-β-D-6-deoxy-3-O-methyl-allopyanoside (1) and 11- O-α-acetyl -12-O-β-benzoate-3β, 14β-dihydroxy-pregn-5-en- 20-one-3-O-β-D-oleadropyranosyl-(1→4)-β-D-6-deoxy-3-O-methyl-allopyanoside (2) were isolated from the roots of Dregea sinensis Hemsl. Their structures were elucidated by various spectroscopic techniques including UV, IR, HRESIMS, 1 D and 2 D NMR. All the two compounds were tested for their cytotoxic activity in vitro, and the result showed that compounds 1-2 displayed moderated cytotoxic activity against HL-60 cell line with IC50 values of 18.4 μM and 23.9 μM, respectively.

HPLC-ESI-MS n Identification and NMR Characterization of Glucosyloxybenzyl 2 R-Benzylmalate Deriva-Tives from Arundina Graminifolia and Their Anti-Liver Fibrotic Effects In Vitro. Molecules 2019; 24:molecules24030525. [PMID: 30709052 PMCID: PMC6385127 DOI: 10.3390/molecules24030525] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2019] [Revised: 01/22/2019] [Accepted: 01/29/2019] [Indexed: 02/06/2023] Open
Abstract
Four new glucosyloxybenzyl 2R-benzylmalate derivatives, named Arundinoside H (2), I (5), J (6), K (8) as well as four known compounds Arundinoside D (1), G (3), F (4), E (7) were isolated and characterized by a combination of chemical and spectroscopic methods, including HR-ESI-MS, 1D and 2D NMR experiments. Besides, 24 unreported compounds were inferred from ESI-MSn data. The anti-liver fibrotic activities of the isolates were determined as proliferation inhibition of lipopolysaccharide (LPS)-induced activation of rat hepatic stellate cells (HSC-T6). The result suggested Arundinosides D, H, F, I and K showed moderate inhibitory effects in vitro.
