A three-component strategy for the synthesis of thiazoles and isothiazoles has been developed by employing enaminoesters, fluorodibromoiamides/ester, and sulfur. The thiazoles and isothiazoles were formed via two C-F bond cleavages along with the formation of new C-S, C-N, and N-S bonds. The strategy provides high selectivity for the synthesis of thiazoles/isothiazoles, which have vital applications in drug discovery and development.

The release of pro-inflammatory mediators, such as prostaglandines (PGs) and leukotrienes (LTs), arising from the arachidonic acid (AA) cascade, play a crucial role in initiating, maintaining, and regulating inflammatory processes. New dual inhibitors of 5-lipoxygenase (5-LO) and microsomal prostaglandin E2 synthase-1 (mPGES-1), that block, at the same time, the formation of PGE2 and LTs, are currently emerged as a highly interesting drug candidates for better pharmacotherapie of inflammation-related disorders. Following our previous studies, we here performed a detailed structure-based design of benzo[g]indol-3-carboxylate derivatives, disclosing several new key factors that affect both enzyme activity. Ethyl 2-(3,4-dichlorobenzyl)-5-hydroxy-1H-benzo[g]indole-3-carboxylate (4b, RAF-01) and ethyl 2-(3,4-dichlorophenyl)-5-hydroxy-1H-benzo[g]indole-3-carboxylate (7h, RAF-02) emerged as the most active compounds of the series. Additionally, together with selected structure based analogues, both derivatives displayed significant in vivo anti-inflammatory properties. In conclusion, modeling and experimental studies lead to the discovery of new candidate compounds prone to further developments as multi-target inhibitors of the inflammatory pathway.

Abstract A new facile synthesis of pyrido[2,3-d]pyrimidin-4-ones via cyclocondensation of 4,6-dichloro-2-methylsulfanylpyrimidine-5-carbaldehyde with β-alkyl and β-aryl-β-aminoacrylic esters followed by hydrolysis of chlorine atom at position 4 of pyridopyrimidine ring has been developed. The cyclocondensation was found to be accelerated by acid.
