Problems solved by technology

In the process of treating stroke, the drug also needs to pass through the blood-brain barrier and reach the effective concentration before it can work. Most of the drug molecules cannot penetrate the blood-brain barrier to reach the brain. Therefore, many drugs for the treatment of brain diseases Some drugs can show good drug-target binding activity in in vitro tests, but they can't show ideal drug effects in animal tests

Embodiment 1

[0087] Synthesis of Compound A: Under nitrogen protection, malonic acid mono(1R,2S,4R)-1,7,7-trimethylbicyclo[2.2.1]heptane-2-ol ester (11.5g, 47.9 mmol), 3-fluoro-4-hydroxyl-5-methoxybenzaldehyde (7.3g, 42.9mmol) were added in toluene (100ml), added pyridine (7.6g, 95.8mmol), piperidine (0.4g, 4.7 mmol), the temperature was raised to 120°C for 5 hours. After the reaction was completed, the reaction solution was allowed to cool, and 1N hydrochloric acid solution, saturated NaHCO 3 solution, washed with saturated NaCl solution, dried over anhydrous sodium sulfate for 4 h, concentrated to dryness, and recrystallized from ethyl acetate / petroleum ether to obtain 10.2 g of white powder solid with a yield of 68.5%.

Description

technical field [0001] The invention belongs to the technical field of chemistry and medicine, and relates to a phenylacrylate compound and its preparation method and application. Background technique [0002] Stroke is a disease in which brain tissue is damaged due to sudden rupture of blood vessels in the brain or blood circulation disorder caused by blood vessel blockage. Ischemic stroke refers to the necrosis of local brain tissue including nerve cells, glial cells and blood vessels due to lack of blood supply. [0003] According to the "China Cardiovascular Disease Report 2013", the prevalence of cerebrovascular diseases in my country is on the rise. According to the 2010 Global Burden of Disease Study, stroke is the third leading cause of disability-adjusted life years (DALYs). At the same time, stroke is the second leading cause of death among people over 60 years old, and it is one of the neurological diseases with the highest fatality rate. In my country, stroke ...
