Mahajan, Sheena published the artcileMalononitrile-activated synthesis and anti-cholinesterase activity of styrylquinoxalin-2(1H)-ones, Product Details of C9H10O3, the main research area is quinoline quinoxaline methyl diastereoselective condensation aryl aldehyde malononitrile activator; styryl quinoxalinone preparation anticholinesterase activity mol modeling; methyl quinoxalinone diastereoselective condensation aryl aldehyde malononitrile activator.

A base-free malononitrile activated condensation of 3-methyl-6-R1-quinoxalin-2(1H)-ones (3MQ) with aryl aldehydes RCHO (R = Ph, 4-ClC6H4, PhCH:CH, thiophen-2-yl, etc.; R1 = H, NO2) for synthesis of styrylquinoxalin-2(1H)-ones (SQs) (E)-I in excellent yields has been described. In this reaction, malononitrile activates the aldehyde via Knoevenagel condensation towards reaction with 3MQ and gets liberated during the course of reaction to yield the desired SQs (E)-I. The SQs (E)-I were evaluated for in vitro cholinesterase inhibition and (E)-I (R = 4-F-3-BrC6H3) was found to display a mixed type of inhibition of AChE, which was supported by mol. modeling studies. The procedure was successfully applied to the synthesis the analogous styrylquinoxalines and styrylquinolines. This study has led to the discovery of a new chemotype for cholinesterase inhibition which might be useful in finding a remedy for Alzheimer’s disease.

Chiasson, Audrey Isabel published the artcileNew zileuton-hydroxycinnamic acid hybrids: synthesis and structure-activity relationship towards 5-lipoxygenase inhibition, COA of Formula: C9H10O3, the main research area is benzothiophene hydroxycinnamic acid preparation SAR lipoxygenase inhibition mol docking; radical scavenging activity pharmacokinetic study; 5-Lipoxygenase inhibitors; anti-leukotrienes; hydroxyurea; inflammation; sinapic acid; zileuton.

A novel series of zileuton-hydroxycinnamic acid hybrids I (R1 = H, OH, OMe; n = 0, 1, 2, 3), II (R2 = C6H5, 4-OHC6H4, 2,6-(CH3)2C6H3, etc.) and III (R3 = H, OH, OMe; R4 = H, OH, OMe; R5 = H, OMe) were synthesized and screened as 5-lipoxygenase (5-LO) inhibitors in stimulated HEK293 cells and polymorphonuclear leukocytes (PMNL). Zileuton’s IV benzo[b]thiophene and hydroxyurea subunits combined with hydroxycinnamic acid esters’ ester linkage and phenolic acid moieties were investigated. Compound II (R2 = 3,5-(OMe)2-4-OHC6H2), bearing zileuton’s IV benzo[b]thiophene and sinapic acid phenethyl ester’s V α,α-unsaturated phenolic acid moiety II (R2 = 3,5-(OMe)2-4-OHC6H2), was shown to be equipotent to zileuton IV, the only clin. approved 5-LO inhibitor, in stimulated HEK293 cells. Compound II (R2 = 3,5-(OMe)2-4-OHC6H2) was three times as active as zileuton IV for the inhibition of 5-LO in PMNL. Compound III (R3 = OMe, R4 = OH, R5 = OMe), bearing the same sinapic acid (3,5-dimethoxy-4-hydroxy substitution) moiety as II (R2 = 3,5-(OMe)2-4-OHC6H2), combined with zileuton’s IV hydroxyurea subunit was inactive. This result shows that the zileuton’s IV benzo[b]thiophene moiety is essential for the inhibition of 5-LO product biosynthesis with hydrids. Unlike zileuton IV, compound II (R2 = 3,5-(OMe)2-4-OHC6H2) formed two π-π interactions with Phe177 and Phe421 as predicted when docked into 5-LO. Compound II (R2 = 3,5-(OMe)2-4-OHC6H2) was the only docked ligand that showed a π-π interaction with Phe177 which may play a part in product specificity as reported.
