The invention relates to the field of chemical synthesis, in particular to a preparation method of neoflavonoids. The preparation method is characterized by comprising the following steps of using substituted benzaldehyde as an initial raw material to be reacted with malonic acid to generate a substituted phenylacrylic acid compound; performing an addition reaction, an elimination reaction and the like on the substituted phenylacrylic acid compound, or performing acetylation so as to protect a phenolic hydroxyl group, then performing a bromination reaction and the elimination reaction so as to synthesize the substituted phenylpropiolic acid compound ; and using montmorillonite K-10 after being acidulated by sulfuric acid as a catalyst, enabling the substituted phenylpropiolic acid compound and a phenolic compound to perform a heating reaction so as to generate the neoflavonoids. Compared with the prior art, the preparation method of the neoflavonoids, disclosed by the invention, has the characteristics that raw materials are cheap, and easy to obtain, the operation is simple, the catalyst can be recovered for use, and the method is environmentally-friendly, the post-treatment is simple, and the production cost is low, and the method has a high popularization and application value.

A total of forty novel glycyrrhetinic acid (GA) derivatives were designed and synthesized. The cytotoxic activity of the novel compounds was tested against two human breast cancer cell lines (MCF-7, MDA-MB-231) in vitro by the MTT method. The evaluation results revealed that, in comparison with GA, compound 42 shows the most promising anticancer activity (IC50 1.88 ± 0.20 and 1.37 ± 0.18 μM for MCF-7 and MDA-MB-231, respectively) and merits further exploration as a new anticancer agent.

Formation of radical fragments from even-electron ions is an exception to the "even-electron rule". In this work, ferulic acid (FA) and isoferulic acid (IFA) were used as the model compounds to probe the fragmentation mechanisms and the isomeric effects o

In this research, three categories of phenylpropanoid glycosides (PPGs) were designed and synthesized with PPGs isolated from Rhodiola rosea L. as lead compounds. Their inhibitory abilities toward acetylcholinesterase (AChE) and xanthine oxidase (XOD) were also tested. Some of the synthetic PPGs exhibited excellent enzyme inhibitory abilities.

A systematic investigation of the human metabolism of hydroxycinnamic acid conjugates was carried out. A set of 24 potential human metabolites of coffee polyphenols has been chemically prepared, and used as analytical standards for unequivocal identifications. These included glucuronide conjugates and sulfate esters of caffeic, ferulic, isoferulic, m-coumaric and p-coumaric acids as well as their dihydro derivatives. A particular focus has been made on caffeic and 3,4-dihydroxyphenylpropionic acid derivatives, especially the sulfate conjugates, for which regioselective preparation was particularly challenging, and have so far never been identified as human metabolites. Ten out of the 24 synthesized conjugates have been identified in human plasma and/or urine after coffee consumption. A number of these conjugates were synthesized, characterized and detected as hydroxycinnamic acid metabolites for the first time. This was the case of dihydroisoferulic acid 3′-O-glucuronide, caffeic acid 3′-sulfate, as well as the sulfate and glucuronide derivatives of 3,4-dihydroxyphenylpropionic acid.
