Title:
DEUTERATED BUTYL PHTHALIDE COMPOUND AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/242765
Kind Code:
A1
Abstract:
The present invention provides a compound represented by the formula (I) or an optical isomer thereof, and a tautomer, a pharmaceutically acceptable salt, a prodrug, a hydrate, or a solvate. The various deuterated compounds and salts and hydrates thereof and prodrugs or solvates provided by the present invention, in comparison with undeuterated butyl phthalide, have improved pharmacokinetics and better metabolic stability; at the same time, the compounds of the present invention reduce the production of the 3-hydroxy metabolite of metabolites which cause toxic side effects, and have a smaller impact effect on liver and kidney functions; in addition, the exposure of the parent drug of the compound of the present invention is significantly increased, raising its bioavailability. It is demonstrated that the compound of the invention is safer and more effective, and it has excellent prospects for application.
