Published: October 2023

Isoxazole derivatives were synthesized via a one-pot method utilizing 2-methylquinoline derivatives as template substrates, sodium nitrite as a nitrogen-oxygen source, and solely using aluminum trichloride as the additive. This approach circumvents the need for costly or highly toxic transition metals and presents a novel pathway for the synthesis of isoxazole derivatives.

The goal of this work was to synthesize new compounds for anticancer evaluation as a trial to obtain new antitumor agents with higher activity and fewer side effects. Therefore, the precursor 2,2'-(1,4-phenylenebis (thiazole-4,2-diyl))bis (3-(dimethylamino)acrylonitrile) was used to synthesize various azolopyrimidine derivatives connected to the thiazole moiety. Compounds -, including pyrazolopyrimidine, triazolopyrimidine, and others, were produced by reacting enaminonitrile with different -nucleophiles.

Functional recovery from brain damage, such as stroke, is a plastic process in the brain. The excitatory glutamate -amino-3-hydroxy-5-methyl-4-isoxazole propionic acid receptor (AMPAR) plays a crucial role in neuronal functions, and the synaptic trafficking of AMPAR is a fundamental mechanism underlying synaptic plasticity. We recently identified a collapsin response mediator protein 2 (CRMP2)-binding compound, edonerpic maleate, which augments rehabilitative training-dependent functional recovery from brain damage by facilitating experience-driven synaptic delivery of AMPARs.

FadD32, a fatty acyl-AMP ligase, plays an indispensable role in mycobacterial mycolic acid synthesis and is a validated target for tuberculosis (TB) drug development. The crystal structure of (Mtb)FadD32 has laid the foundation of structure-based drug discovery against this crucial enzyme. Here, we screened the "isoxazole" scaffold containing molecules against MtbFadD32 and identified a compound 2,4-dibromo-6-[3-(trifluoromethyl)-1,2-oxazol-5-yl]phenol (M1) with specific inhibitory activity against Mtb.

Methods for the preparation of 3-aryl-2-azirine-2,2-dicarboxylic acids and their amides, esters, and azides by FeCl-catalyzed isomerization of 3-aryl-5-chloroisoxazole-4-carbonyl chlorides into 3-aryl-2-azirine-2,2-dicarbonyl dichlorides followed by their reaction with nucleophiles are reported. Two approaches to the preparation of 3-aryl-5-chloroisoxazole-4-carbonyl chlorides have been developed.

Article Synopsis
  • The study focuses on the synthesis and anti-inflammatory effects of thirteen new substituted-isoxazole derivatives (5a-5m), which are important compounds in medicinal chemistry.
  • The main goals were to create these new compounds, evaluate how they interact with COX-1/2 enzymes using computational methods, and test their anti-inflammatory effects in lab animals.
  • Results show that three of the compounds exhibited significant anti-inflammatory properties and low toxicity, suggesting potential for further medicinal use.
