Method for preparing heterocyclic-carboxylic acids

The present invention relates to a method for preparing quinoxaline-5- and 6-carboxylic acids. The method comprises contacting an aqueous suspension of a 5- or 6-hydroxymethyl quinoxaline with oxygen in the presence of a transition metal catalyst, to form the respective quinoxaline-5- or 6-carboxylic acid. The method for oxidizing benzylic methyl groups may also be employed to prepare a wide variety of heterocyclic carboxylic acid compounds.

Design, synthesis, biological evaluation and molecular docking study on peptidomimetic analogues of XK469

XK469 is identified as a potent quinoxaline antineoplastic agent based on its significant clinical efficacy. It probably exerts its activity via DNA topoisomerase II (topo II) inhibition. To obtain more effective antineoplastic agents, a spectrum of peptidomimetic-type quinoxaline analogues of XK469 was herein designed, synthesized, and evaluated. Few compounds (e.g. 13a and 13b) exhibited obvious cytotoxicity indicated by in?vitro anti-proliferative assay. SAR investigation revealed that introducing of hydrophobic tert-butylamine or dodecylamine moiety at the 3-position of quinoxaline core is favorable for achieving a better anti-proliferative potency, while peptidomimetic derivatives only yielded moderate cytotoxicity. Compounds with improved anti-proliferative activities also demonstrated decent anti-metastatic potencies comparable with that of doxorubicin (Doxo) based on in?vivo mouse model study. The topo II-mediated kinetoplast DNA (kDNA) decatenation assay as well as molecular docking studies implicated that these compounds tend to be potent topo II inhibitors. Overall, compounds 13a and 13b, 13b in particular, standed out from various assessments and might be promising candidates for further chemical optimization.

Aqueous hydrofluoric acid catalyzed facile synthesis of 2,3,6-substituted quinoxalines

A versatile synthetic route for the preparation of 2,3,6-trisubstituted quinoxalines in excellent yield is developed from theta-diamines and 1,2-dicarbonyl compounds in which aqueous hydrofluoric acid was employed as the medium and catalyst. Other salient features of this protocol include milder conditions, absence of coupling agents, and easy workup procedures.

Novel Antagonists of 5-HT3 Receptors. Synthesis and Biological Evaluation of Piperazinylquinoxaline Derivatives

A series of piperazinylquinoxalines has been synthesized and studied as 5-HT3 receptor antagonists in different preparations.Antagonism to 5-HT in the longitudinal muscle of the guinea pig ileum was particularly prominent in cyanoquinoxaline derivatives with an alkyl substituent on the piperazine moiety.The pA2 of some selected compounds against the 5-HT3 agonist 2-methyl-5HT in the guinea pig ileum was in the range of tropisetron or ondansetron, and one of them, 7e, was more potent than these reference compounds by approximately 2 or 3 orders of magnitude.However, these compounds were markedly less potent than either tropisetron or ondansetron as displacers of 3H-BRL 43694 binding to rat cortical membranes or as antagonists of the Bezold-Jarisch reflex in rats.Piperazinylcyanoquinoxalines represent a new class of 5-HT3 antagonists with a selective effect on guinea pig peripheral receptors.

Present status of quinoxaline motifs: Excellent pathfinders in therapeutic medicine

Quinoxalines belong to a class of excellent heterocyclic scaffolds owing to their wide biological properties and diverse therapeutic applications in medicinal research. They are complementary in shapes and charges to numerous biomolecules they interact with, thereby resulting in increased binding affinity. The pharmacokinetic properties of drugs bearing quinoxaline cores have shown them to be relatively easy to administer either as intramuscular solutions, oral capsules or rectal suppositories. This work deals with recent advances in the synthesis and pharmacological diversities of quinoxaline motifs which might pave ways for novel drugs development.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

An iminodibenzyl-quinoxaline-iminodibenzyl scaffold as a mechanochromic and dual emitter: donor and bridge effects on optical properties

The influence of phenyl linkage and donor strength on the photophysical properties of new derivatives of quinoxaline-containing iminodibenzyl and iminostilbene moieties is studied. The donor-acceptor derivatives showed dual thermally activated delayed fluorescence (TADF) and room temperature phosphorescence (RTP) despite a large energy gap between the excited singlet and triplet states (ca. 0.5 eV). This extremely rare observation is explained by the twisted and rigidified structure of the iminodibenzyl moiety.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 2213-63-0 is helpful to your research. Synthetic Route of 2213-63-0

Preparation and Reactions of 2-Alkynyl-3-chloroquinoxalines.

2-Alkynyl-3-chloroquinoxalines are prepared from 2,3-dichloroqionoxaline and alk-1-ynes: use of 2-methylbut-3-yn-2-ol, and the removal of acetone with base, yields 2-chloro-3-ethynylqionoxaline.The chloroalkynes are readily converted into pyrrolo- and thieno<2,3-b>qionoxalines. 2-Chloro-3-phenylethynylquinoxaline with potassium hydroxide gives 2-phenylfurano<2,3-b>quinoxaline but other furano-compounds could not be prepared. 2-Chloro-3-(3-hydroxy-3-methylbut-2-ynyl)quinoxaline with ethanolic sodium ethoxide yields 2H-2,2-dimethyl-3-ethoxypyrano<2,3-b>quinoxaline.When 2-ethynyl- or 2-chloro-3-ethynylqionoxaline is heated with morpholine and sulphur, 2-morpholinothieno<2,3-b>quinoxaline is obtained.The structures of these compounds are established by spectroscopic methods.
