Embodiment 1
[0057] Embodiment 1. compound general synthetic method
[0058] Dissolve uracil derivative (10mmol) and 4-dimethylaminopyridine (0.5mmol) in pyridine (20mL), heat up to 60°C, slowly add isocyanate (20mmol) dropwise, and react at this temperature for 5h. Pyridine was distilled off under reduced pressure, and the residue was purified by silica gelcolumn chromatography to obtain the product.

Abstract
The invention discloses a carbamyl uracil derivative and application thereof. The structural formula of the derivative is as shown in the description. The derivative is a novel compound with the endogenous cannabinoidhydrolase inhibiting function, and a new method is provided for inflammation and pain treatment.
Description
technical field [0001] The invention belongs to the technical field of medical organic chemistry, and specifically relates to a carbamoyluracil derivative and an application thereof. Background technique [0002] Tetrahydrocannabinol (Tetrahydrocannabinol, THC for short) acts on receptors of cannabinoidreceptor type 1 or type 2 (cannabinoidreceptor 1 / 2, CB1 or CB2 for short). The discovery prompted scientists to investigate endogenous ligands for cannabinoid receptors. N-arachidonoyldopamine (N-arachidonoyldopamine) and other endocannabinoids have been found to act on cannabinoid receptors. . Like lipid transmitters such as prostaglandins, these endocannabinoids do not accumulate in the body, but are synthesized locally on demand, and are regulated by enzymes and receptors, and can be metabolized into corresponding cannabinoids by their specific hydrolytic enzymes. Fatty acids and substances such as ethanolamine and glycerin, thereby reducing the effect of such substanc...
