Embodiment 1

[0089] Preparation of N-(benzo[d][1,3]dioxol-5-ylmethyl)anthracene-9-carboxamide

[0090]

[0091] Anthracene-9-carboxylic acid (114 mg, 0.51 mmol) was dissolved in anhydrous DMF, HATU (235 mg, 0.6 mmol), 1 mL DIEA were added, and after stirring for 5 minutes, piperine (79 mg, 0.52 mmol) was added and reacted at room temperature for 24 h. TLC monitoring, after the reaction of the raw materials was completed, the reaction solution was poured into 50mL of 1N dilute hydrochloric acid solution, a large amount of white solids were precipitated, the mixed solution was allowed to stand overnight, filtered, and dried to obtain compound 1 with a yield of 84.1%.

Embodiment 2-4

[0093] Example 1 was repeated, with the difference that different raw materials were used to obtain compounds 2, 14, and 27 in Table 1. The details are as follows: Use 1-naphthoic acid to replace the raw material anthracene-9-carboxylic acid in Example 1 to obtain compound 2; use 2,5-dichlorobenzoic acid and 2,4-dichloronicotinic acid to replace the raw materials in Example 1 Anthracene-9-carboxylic acid and (6-methoxypyridin-3-yl)methanamine were used instead of the raw material piperine in Example 1 to prepare compounds 14 and 27, respectively.

Embodiment 5

[0095] Preparation of 2-((benzo[d][1,3]dioxol-5-ylmethyl)carbamoyl)-3-chlorobenzoic acid

[0096]

[0097] 1) Preparation of 2-chloro-6-((2-ethoxy-2-oxoethyl)carbamoyl)benzoic acid

[0098] 4-Chloroisobenzofuran-1,3-dione (274mg, 1.5mmol) was dissolved in 10mL ethyl acetate, stirred at room temperature to dissolve, and 2-aminoacetate ethyl ester (155mg, 1.5mmol) was added dropwise, Can produce a large amount of white solids immediately, TLC monitors, and after the reaction is completed, stand and filter, and dry to obtain the intermediate 2-chloro-6-((2-ethoxyl-2-oxoethyl)carbamoyl)benzoic acid , 90% yield.

[0099] 2) Preparation of methyl 2-(2-((benzo[d][1,3]dioxol-5-ylmethyl)carbamoyl)-3-chlorobenzamido)acetate

[0100] Dissolve the intermediate 2-chloro-6-((2-ethoxy-2-oxoethyl)carbamoyl)benzoic acid (213mg, 0.51mmol) in anhydrous DMF, add HATU (235mg, 0.6mmol ), 1mL DIEA, stirred for 5 minutes, added piperine (79mg, 0.52mmol), reacted at room temperature for 24h, mon...

Abstract

The invention belongs to the technical field of medicinal chemistry, in particular to an amides aldehyde dehydrogenase agonist as well as a synthesis method and application thereof. The amides compound provided by the invention shows the relatively high agonist activity on ALDH2, therefore the compound has the potential for preparing drugs for treating diseases related to ALDH2 activity; (2) the amides compound makes great improvement on the activity and the water solubility compared with a positive control substance, and has the better druggability. In this way, the compound has the good development prospects.

Description

technical field [0001] The invention belongs to the technical field of medicinal chemistry, and in particular relates to a class of amide-type aldehyde dehydrogenase agonists, its synthesis method and application. Background technique [0002] Aldehyde dehydrogenase 2 (ALDH2) is responsible for the detoxification of acetaldehyde produced by exogenous alcohol metabolism in the body and acrolein in environmental pollution; it is also responsible for the endogenous oxidative stress of lipid peroxidation end product 4- The detoxification of hydroxynonenal (4-HNE) and malondialdehyde (MDA) is an important part of the oxidative stress defense system in the body (Physiol Rev.2014, 94(1):1-34; Cardiovasc Res.2010, 88(1):51-7). ALDH2 has single-nucleotide mutations with obvious species differences. About 35–45% of East Asian populations carry the low-activity variant ALDH2*2, and it can be as high as 65% in some parts of southern China, while the proportion in other races is extreme...
