Structure-activity relationships in a series of 3-sulfonylamino-2-(1H)-quinolones, as new AMPA/kainate and glycine antagonists

This paper describes the design and synthesis of a new class of molecules, the 3-sulfonylamino-2-(1H)-quinolones, which are potent and selective antagonists at both the AMPA/kainate site as well as at the NMDA-associated glycine site. The molecules were characterized by their binding affinities to rat cortical membranes and by electrophysiology on Xenopus oocytes injected with mRNA isolated from rat cerebral cortex. The most potent compound 61 has an IC50 of 0.09 muM for binding at the AMPA/kainate site, and 0.16 muM in oocyte electrophysiology.

A novel method for heterocyclic amide-thioamide transformations

In this paper, we introduce a novel and convenient method for the transformation of heterocyclic amides into heteocyclic thioamides. A two-step approach was applied for this transformation: Firstly, we applied a chlorination of the heterocyclic amides to afford the corresponding chloroheterocycles. Secondly, the chloroherocycles and N-cyclohexyl dithiocarbamate cyclohexylammonium salt were heated in chloroform for 12 h at 61C to afford heteocyclic thioamides in excellent yields.

Carbon-13 NMR Studies on some 5-Substituted Quinoxalines

Eleven 5-substituted quinoxalines (NO2, NH2, COOH, OCH3, CH3, OH, F, Cl, Br, I, CN, the latter five not reported previously) have been synthesized by standard methods.Their 13C NMR spectra have been measured in DMSO-d6 and assigned on the basis of substituent parameters, by line widths and by intensities.The chemical shifts compare favorably with those calculated using benzene substituent parameters, and are very close to those of corresponding carbons in 1-substituted phenazines.The correlation with the chemical shifts of the corresponding positions in 1-substituted naphthalenes is also close except for those of carbons 4a and 8a in the quinoxalines which, due to their proximity to nitrogen, are downfield (in some cases 12 ppm) of the signals of the corresponding carbons in naphthalene. 5-Fluoroquinoxaline was also measured in CDCl3, CD3COCD3, CD3CN, CD3OD, C6D6 and CD3COOD.In all solvents an abnormally low 2J(CF) (ca. 12 Hz) was found for C-4a and no C-F spin-spin splitting could be detected for the three-bond coupling of C-8a.Similar abnormalities were found in 2-fluoroaniline and 2-fluoroacetanilide.There are linear relationships between the Q parameter of the substituent and the chemical shift of carbons 4a, 5 and 6.A linear relationship also exists between the chemical shift of C-8 (‘para’ position) and the Hammett ?p parameter of the substituent.

Fundamental studies and development of nickel-catalyzed trifluoromethylthiolation of aryl chlorides: Active catalytic species and key roles of ligand and traceless MeCN additive revealed

A catalytic protocol to convert aryl and heteroaryl chlorides to the corresponding trifluoromethyl sulfides is reported herein. It relies on a relatively inexpensive Ni(cod)2/dppf (cod = 1,5-cyclooctadiene; dppf = 1,1?-bis(diphenylphosphino)ferrocene) catalyst system and the readily accessible coupling reagent (Me4N)SCF3. Our computational and experimental mechanistic data are consistent with a Ni(0)/Ni(II) cycle and inconsistent with Ni(I) as the reactive species. The relevant intermediates were prepared, characterized by X-ray crystallography, and tested for their catalytic competence. This revealed that a monomeric tricoordinate Ni(I) complex is favored for dppf and Cl whose role was unambiguously assigned as being an off-cycle catalyst deactivation product. Only bidentate ligands with wide bite angles (e.g., dppf) are effective. These bulky ligands render the catalyst resting state as [(P-P)Ni(cod)]. The latter is more reactive than Ni(P-P)2, which was found to be the resting state for ligands with smaller bite angles and suffers from an initial high-energy dissociation of one ligand prior to oxidative addition, rendering the system unreactive. The key to effective catalysis is hence the presence of a labile auxiliary ligand in the catalyst resting state. For more challenging substrates, high conversions were achieved via the employment of MeCN as a traceless additive. Mechanistic data suggest that its beneficial role lies in decreasing the energetic span, therefore accelerating product formation. Finally, the methodology has been applied to synthetic targets of pharmaceutical relevance.

Reactions of 2,3-dichloroquinoxaline 1 with various acid hydrazides 2 in acetonitrile under PTC conditions give the corresponding oxadiazinoquinoxalines 3, which on reaction with sodium alkoxides in alcohol yielded the respective ring opened products i.e. 2-acylhydrazino-3-alkoxyquioxalines 4. The compound 4 has been also synthesised from 2-acylhydrazino-3-chloroquinoxaline 5, which is obtained by the reaction of 1 with 2 in DMF at room temperature.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C9H7ClN2O, you can also check out more blogs about32998-25-7
