Peganumine A alkaloid structure simplifier and application thereof
-
Paragraph 0037-0041; 0056-0058, (2021/06/26)
The invention discloses a Peganumine A alkaloid structure simplifier, a stereoisomer or a pharmaceutical salt thereof. The structure is shown in the following general formula: each substituent group is defined in the specification. The simplified structure of the Peganumine A alkaloid provided by the invention has a relatively obvious proliferation inhibition effect on liver cancer HepG2, lung cancer A549 and intestinal cancer HCT116, and the anti-tumor activity of part of compounds is higher than the anti-liver cancer HepG2 activity of Peganumine A reported in literatures.

The total synthesis of four natural products, trigonostemine A, trigonostemine B, pityriacitrin, and hyrtiosulawesine was accomplished. The key intermediates, variously substituted 1-formyl-β-carbolines, were prepared in five steps via a novel synthetic approach using readily available starting materials. These formyl derivatives were then further transformed, providing a general route for the synthesis of the four title alkaloids. The method reported herein represents the first total synthesis of the two trigonostemines and a new pathway to pityriacitrin and hyrtiosulawesine.

In the course of studies directed toward the discovery of novel acetyl- and butyrylcholinesterase (AChE and BChE) inhibitors for the treatment of Alzheimer's disease, we focused on β-carbolines (BCs). 6-Oxygenated β-carboline and β-carbolinium derivatives based on the serotonin template were synthesized and tested in vitro for their ability to inhibit AChE and BChE, respectively. Particularly the carbolinium salts, which can be formed by intracerebral methylation out of the tertiary-BC prodrugs, show inhibitory activity levels reaching those of galantamine, physostigmine, and rivastigmine.
