DC-SIGN is a cell-surface receptor for several pathogenic threats, such as HIV, Ebola virus, or Mycobacterium tuberculosis. Multiple attempts to develop inhibitors of the underlying carbohydrate?protein interactions have been undertaken in the past fifteen years. Still, drug-like DC-SIGN ligands are sparse, which is most likely due to its hydrophilic, solvent-exposed carbohydrate-binding site. Herein, we report on a parallel fragment screening against DC-SIGN applying SPR and a reporter displacement assay, which complements previous screenings using 19F NMR spectroscopy and chemical fragment microarrays. Hit validation by SPR and 1H?15N HSQC NMR spectroscopy revealed that although no fragment bound in the primary carbohydrate site, five secondary sites are available to harbor drug-like molecules. Building on key interactions of the reported fragment hits, these pockets will be targeted in future approaches to accelerate the development of DC-SIGN inhibitors.

A novel palladium-catalyzed synthesis of 1,2-dihydroquinoxalines and 3,4-dihydroquinoxalinones.

Reactions of enamines, derived from 2-nitroanilines and alpha-substituted aldehydes, with carbon monoxide (6 atm) in the presence of a catalytic amount of bis(dibenzylideneacetone)palladium(0) (Pd(dba)(2)) and 1,3-bis(diphenylphosphino)propane (dppp) afford readily separated mixtures of 1,2-dihydroquinoxalines and 3,4-dihydroquinoxalinones.

Antagonist, Partial Agonist, and Full Agonist Imidazo<1,5-a>quinoxaline Amides and Carbamates Acting through the GABAA/benzodiazepine Receptor

(4RS)-1-(5-Cyclopropyl-1,2,4-oxadiazol-3-yl)-12,12a-dihydroimidazo<1,5-a>pyrrolo<2,1-c>quinoxalin-10(11H)-one (1a), 5-benzoyl-3-(5-cyclopropyl-1,2,4-oxadiazol-3-yl)-4,5-dihydroimidazo<1,5-a>quinoxaline (13b), and tert-butyl (4S)-12,12a-dihydroimidazo<1,5-a>pyrrolo<2,1-c>quinoxaline-1-carboxylate (1e), as well as other imidazo<1,5-a>quinoxaline amides and carbamates, represent a new series of compounds which bind with high affinity to the GABAA/benzodiazepine receptor.These compound exhibit a wide range of intrinsic efficacies as measured by <35S>TBPS binding ratios.The synthesis of 1a begins with the addition of DL-glutamic acid to 1-fluoro-2-nitrobenzene, followed by reduction of the nitro group and subsequent ring closure to form 3-(carbethoxymethyl)-1,2,3,4-tetrahydroquinoxalin-2-one, followed by a second ring closure to afford (4RS)-1,5-dioxo-1,2,3,4,5,6-hexahydropyrrolo<1,2-a>quinoxaline as the key intermediate.Appendage of a substituted imidazo ring via the anion of 5-cyclopropyl-1,2,4-oxadiazol-3-yl gives 1a.The (-) and (+)-isomers of 1a were prepared from 1-fluoro-2-nitrobenzene and L- and D-glutamic acid, respectively. 1a and its enantiomers demonstrated affinity for <3H>flunitrazepam binding site with Ki’s of 0.87, 0.62, and 0.65 nM, respectively.

A new facile, efficient synthesis and structure peculiarity of quinoxaline derivatives with two benzimidazole fragments

A highly efficient and versatile method for the synthesis of quinoxaline derivatives with two benzimidazole fragments have been developed on the basis of the ring contraction of 3-(benzimidazo-2-yl)quinoxalin-2(1H)-one with 1,2-diaminobenzene and its various types of substituted and condensed derivatives. Owing to the inter- and intramolecular processes, involving self association, proton exchange, conformational, and/or tautomeric exchanges between several forms for most of the bis-benzimidazolylquinoxalines signals of bridged and neighboring carbon atoms and the hydrogen atoms of the neighboring carbon atoms of benzimidazole fragments in the NMR spectra are broadened. The conjugation between the benzimidazole fragments and the quinoxaline core of the molecules is increased from the quinoxaline derivative (10c) to its thiadiazol[f]- (17) and pyrrolo[a]-(19) annulated derivatives, resulting in a greater planarity of the molecule as a whole.

Practical synthesis of 3,3-substituted dihydroquinoxalin-2-ones from aryl 1,2-diamines using the Bargellini reaction

The reaction of aromatic 1,2-diamines with trichloromethylcarbinols under mild, basic phase-transfer conditions provided expedient access to 3,3-disubsituted quinoxalin-2(1H)-ones in good to moderate yields. The use of unsymmetrical aryl diamines gave a regioisomeric mixture of products with the ratio shown to be dependent on the electronic nature of the aromatic substituents. 2,3-Diaminopyridines could also be used, showing excellent selectivity for the dihydro[3,2-b]pyridopyrazin-2-one isomer.
