Abstract

The invention discloses a synthetic method for a quinazolinone FPR2 formyl peptide receptor agonist. The method is specifically implemented according to the following steps of: weighing isatoic anhydride, an aromatic hydrazide compound and an aromatic aldehyde compound with the ratio of amount of substance of 1:1:1 as raw materials; after mixing the raw materials in a solvent, performing a one-pot synthetic reaction by taking a nano metal oxide as a catalyst; and separating and purifying a reaction product after the reaction by virtue of column chromatography to obtain the quinazolinone FPR2 formyl peptide receptor agonist. The synthetic method disclosed by the invention reduces the complexity of preparation by simplifying the preparation process, and moreover, the reaction condition is mild, the raw materials are low in price and are easily available, the product is high in yield, and the solvent in the preparation process is non-toxic, so that the synthetic method has a good industrial application prospect.

Description

technical field [0001] The invention belongs to the field of organic synthesis and relates to a synthesis method of a quinazolinone FPR2 formyl peptide receptor agonist. Background technique [0002] Quinazolinone compounds are an important nitrogen-containing heterocyclic compound. About 150 alkaloids isolated from natural products have quinazolinone ring skeletons, which exhibit good biological activities in antibacterial and anti-inflammatory. It also has good pharmacological activity in anti-hypertension, anti-tumor, and anti-HIV. The green and efficient synthesis of quinazolinone compounds with medicinal value has become a hot topic of widespread concern. QuinC1 is a non-peptide formyl peptide receptor agonist with quinazolinone as the backbone. Formyl peptide receptor agonists play a key role in the regulation of inflammatory responses and the defense of sensory cell dysfunction. , non-peptide small molecule agonists have become a better choice for clinical applicatio...
