Paragraph 0085-0092, (2020/05/30)
The invention provides a preparation method of apabetalone. The preparation method comprises the step of reacting a first intermediate, namely 2-bromo-4,6-dimethoxybenzoic acid with a second intermediate, namely 4-(2-hydroxyethoxy)-3,5-dimethylbenzamidine hydrochloride in an alkali-containing organic solvent under the action of a catalyst so as to obtain apabetalone. According to the invention, total yield is 33.4% or above, raw materials are easy to obtain, process is simple, reaction conditions are mild, post-treatment method is simple, the yield of each step and the total yield are high, and cost can be reduced. Apabetalone is a medicine for treating cardiovascular diseases such as atherosclerosis and the like, and has good application prospects. The invention also provides the intermediate 4-(2-hydroxyethoxy)-3,5-dimethylbenzamidine hydrochloride for synthesizing apabetalone and a preparation method thereof, and a preparation method of the compound 2-bromo-4,6-dimethoxybenzoic acid.

Bromodomain-containing protein 4 (BRD4) is a new therapeutic target for the treatment of diseases including cardiovascular diseases, cancer, inflammation and central nervous system (CNS) disorders. In this study, we introduced the pharmacophore of fibrates to a BRD4 inhibitor, RVX-208, to design dual-active hypolipidemic compounds, and found that some of new analogues showed favorable hypolipidemic activities. Synthetic accessibility towards this class of compounds optimized RVX-208 as well as would supply more thoughts on hypolipidemic drugs.
