Abstract
A chemical study of Aesculus wilsonii Rehd. (also called Suo Luo Zi) and the in vitro anti-inflammatory effects of the obtained compounds was conducted. Retrieving results through SciFinder showed that there were four unreported compounds, aeswilosides I-IV (1-4), along with fourteen known isolates (5-18). Their structures were elucidated by extensive spectroscopic methods such as UV, IR, NMR, [α]D, and MS spectra, as well as acid hydrolysis. Among the known ones, compounds 5, 6, 8-10, and 12-16 were obtained from the Aesculus genus for the first time; compounds 7, 11, 17, and 18 were first identified from this plant. The NMR data of 5 and 18 were reported first. The effects of 1-18 on the release of nitric oxide (NO) from lipopolysaccharide (LPS)-induced RAW264.7 cells were determined. The results showed that at concentrations of 10, 25, and 50 μM, the novel compounds, aeswilosides I (1) and IV (4), along with the known ones, 1-(2-methylbutyryl)phloroglucinyl-glucopyranoside (10) and pisuminic acid (15), displayed significant inhibitory effects on NO production in a concentration-dependent manner. It is worth mentioning that compound 10 showed the best NO inhibitory effect with a relative NO production of 88.1%, which was close to that of the positive drug dexamethasone. The Elisa experiment suggested that compounds 1, 4, 10, and 15 suppressed the release of TNF-α and IL-1β as well. In conclusion, this study enriches the spectra of compounds with potential anti-inflammatory effects in A. wilsonii and provides new references for the discovery of anti-inflammatory lead compounds, but further mechanistic research is still needed.

Cao H, Ruan J, Cao X, Zhang Y, Hao J, Wu Y, Zhang Y, Wang T. Nitrogenous compounds from Aesculus wilsonii seeds. Fitoterapia 2024; 172:105783. [PMID: 38110127 DOI: 10.1016/j.fitote.2023.105783] [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: 09/04/2023] [Revised: 12/07/2023] [Accepted: 12/14/2023] [Indexed: 12/20/2023]
Abstract
Eight nitrogenous compounds including five undescribed ones, aeswilnitrousol A (1), aeswilnitrousosides BD (2-4), and 6-(2-hydroxy-3-methylbutylamino)-8-oxoadenine (5) were isolated from the seeds of Aesculus wilsonii. Their structures and absolute configurations were established based on spectroscopic determination, calculated electronic circular dichroism (ECD) analysis, as well as chemical reaction methods. Among the three known compounds, 7 and 8 were obtained from the Aesculus genus for the first time, and 6 was gained from this plant initially. The 13C NMR data of 7 and 8 were reported for the first time. Moreover, the inhibitory effect of all the isolates against LPS-induced nitric oxide production in RAW264.7 macrophages was evaluated. As a result, compounds 2 and 8 exhibited anti-inflammatory activity in a concentration-dependent manner at 10, 25, and 50 μM.
