Synthesis and biological evaluation of new quinoxaline derivatives as antioxidant and anti-inflammatory agents.
We report the synthesis, anti-inflammatory, and antioxidant activities of novel quinoxaline and quinoxaline 1,4-di-N-oxide derivatives. Microwave-assisted methods have been used to optimize reaction times and to improve yields. The tested compounds presented important scavenging activities and promising in vitro inhibition of soybean lipoxygenase (LOX). Two of the best LOX inhibitors (compounds...
متن کاملSinapic Acid Derivatives as Potential Anti-Inflammatory Agents: Synthesis and Biological Evaluation
Transcription factor NF-κB and relevant cytokines IL-6 and IL-8 play a pivotal role in thepathogenesis of inflammation. Sinapic acid is a natural product and was demonstrated to possessanti-inflammatory activity. In this paper, we synthesized a series of sinapic acid derivativesand evaluated their anti-inflammatory effects. The result suggested that all of the targetscompounds 7a-j inhibit NF-κ...

متن کاملSynthesis, biological evaluation and structure-activity relationships of new quinoxaline derivatives as anti-Plasmodium falciparum agents.
We report the synthesis and antimalarial activities of eighteen quinoxaline and quinoxaline 1,4-di-N-oxide derivatives, eight of which are completely novel. Compounds 1a and 2a were the most active against Plasmodium falciparum strains. Structure-activity relationships demonstrated the importance of an enone moiety linked to the quinoxaline ring.
متن کاملMicrowave-Assisted Synthesis and Biological Evaluation of Dihydropyrimidinone Derivatives as Anti-Inflammatory, Antibacterial, and Antifungal Agents
A simple protocol for the efficient preparation of aryl and heteroaryl substituted dihydropyrimidinone has been achieved via initial Knoevenagel, subsequent addition, and final cyclization of aldehyde, ethylcyanoacetate, and guanidine nitrate in the presence of piperidine as a catalyst in solvent-free under microwave irradiation. The synthesized compounds showed a good anti-inflammatory, antiba...
