Problems solved by technology

In the previous research, we designed and synthesized scutellarin aglycon carbamate derivatives (CN101337956A, CN102603698A), stilbene or ethane carbamate for the acetylcholinesterase and oxidative stress factors in the pathogenesis of AD Ester compounds (CN102816090A), isoflavone carbamate compounds (CN102827131A), flavonoid alkylamine compounds (CN103087024A), genistein alkylamine compounds (CN103113340A), stilbene oxyalkylamine compounds (CN103073440A), although these compounds have good acetylcholinesterase inhibitory and antioxidant activities, but for A β 1-42 Inhibition of self-aggregation (inhibition rates of less than 65.0% at 20.0 µM concentration), Cu 2+ Induced A β 1-42 Inhibition of aggregation (inhibition rates of less than 65.0% at a concentration of 20.0 µM) and 2+ Induced A β 1-42 The aggregation disaggregation activity (the disaggregation rate is less than 60.0% at the concentration of 20.0µM) is not satisfactory, resulting in the poor efficacy of these compounds on AD in animal models

Embodiment 1

[0035] Example 1 General method for the preparation of 2-hydroxychalcone amines (I)

[0036] Add 2.0 mmol of the corresponding 2-hydroxyacetophenone compound (2), 3.0 mmol of the corresponding benzaldehyde compound (1) and 30 ml of ethanol into the reaction flask, stir well, then add 12.0 mmol of 30% KOH aqueous solution dropwise, Stir and react at 40-50°C for 2.0 to 72.0 hours (the reaction progress is tracked by TLC); after the reaction, cool to room temperature, adjust the pH of the reaction solution to strong acidity with 10% hydrochloric acid aqueous solution, and then adjust the pH of the reaction solution with saturated sodium bicarbonate aqueous solution To weak alkalinity, evaporate ethanol under reduced pressure, add 100 mL deionized water to the residual liquid, extract three times with 300 mL dichloromethane, combine organic layers, wash with saturated aqueous sodium chloride solution, and dry over anhydrous sodium sulfate After filtration, the solvent was evaporat...

Embodiment 2

[0061] Example 2 General method for the preparation of 2-hydroxychalcone amine compound (I) and acid salt formation

[0062] Add 2.0 mmol of 2-hydroxychalcone amine compound (I) obtained according to the above-mentioned Example 1 and 50 ml of acetone into the reaction flask, stir well, add 8.0 mmol of the corresponding acid, heat 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 2-hydroxychalcone amine compound (I). 1 Confirmed by H NMR and ESI-MS.
