Problems solved by technology

[0003] AD is a disease caused by multiple factors, and its pathogenesis is complex. Its pathogenesis has not yet been fully elucidated. However, studies have shown that the decline in the level of acetylcholine in the brain of patients, the excessive production and deposition of β-amyloid protein, and the disorder of metal ion metabolism. Ca 2+ imbalance, tau - Various factors such as neurofibrillary tangles caused by protein hyperphosphorylation, excessive activity of glutamate receptors, large amounts of reactive oxygen species (ROS) and free radicals produced by oxidative stress, and neuroinflammation play an important role in the pathogenesis of AD Role
In response to the above-mentioned pathogenic factors, researchers adopted the traditional "one drug, one target" drug design strategy, and discovered a large number of drugs with high activity and high selectivity for a certain target, such as: cholinesterase inhibitors and N -methyl- D - Aspartate receptor antagonists, etc., but these drugs have problems such as a single target, more toxic and side effects in clinical use, and poor long-term curative effect on AD patients

Embodiment 1

[0034] Example 1 General method for the preparation of high isoflavone Mannich base compounds (I)

[0035] Add 2.0 mmol of the corresponding chromanone compound (1), 3.0 mmol of the corresponding hydroxybenzaldehyde Mannich base compound (2) and 30 ml of methanol into the reaction flask. After stirring evenly, add 30% KOH aqueous solution 12.0 mmol, heated and refluxed and stirred for 3.0 to 24.0 hours (the reaction process was tracked by TLC); after the reaction, cooled to room temperature, adjusted the pH of the reaction solution to strong acidity with 10% aqueous hydrochloric acid solution, and then adjusted the pH of the reaction solution with saturated aqueous sodium bicarbonate solution To weak alkalinity, methanol was evaporated under reduced pressure, 80 mL of deionized water was added to the residual liquid, extracted three times with 240 mL of dichloromethane, the organic layers were combined, washed with saturated aqueous sodium chloride solution, dried over anhydrou...

Embodiment 2

[0043] Example 2 General method for the preparation of high isoflavone Mannich base compound (I) and acid salt formation

[0044] Add 2.0 mmol of the high isoflavone Mannich base compound (I) obtained according to the above Example 1 and 50 ml of acetone into the reaction flask, stir evenly, add 8.0 mmol of the corresponding acid, heat up and reflux and stir for 20 minutes, and the reaction is over After cooling to room temperature, the solvent was evaporated under reduced pressure, the residue was recrystallized with acetone, and the precipitated solid was filtered to obtain the salt of the high isoflavone Mannich base compound (I). 1 Confirmed by H NMR and ESI-MS.
