NUCLEOPHILIC SUBSTITUTIONS ON 2-CHLORO-3-NITROQUINOXALINE

Piperidine, cyclohexylamine, methoxide ion and para-thiocresolate ion react with 2-chloro-3-nitroquinoxaline 1 by selectively substituting the nitro group, in contrast to be behavior of most ortho-chloronitroaromatics which loose halide when subjected to nucleophilic substitution reactions.This inversion is interpreted as being due to the lack of activation of the 2-position by the nitro group in the 3-position because of the low value of the ?-bond index between these two vertices.It is also suggested that the substitution by neutral reagents such as amines is strongly influenced by stabilizing interactions between the negatively charged nitro group and the ammonium moiety in the ? complex; this built-in solvation may be responsible for inversions in the chemoselectivity between chloro and nitro nucleofugicities.

Fragment based design of new H4 receptor-ligands with anti-inflammatory properties in vivo

Using a previously reported flexible alignment model we have designed, synthesized, and evaluated a series of compounds at the human histamine H 4 receptor (H4R) from which 2-(4-methyl-piperazin-l-yl)- quinoxaline (3) was identified as a new lead structure for H4R ligands. Exploration of the structure-activity relationship (SAR) of this scaffold led to the identification of 6,7-dichloro 3-(4-methylpiperazin-l-yl) quinoxalin-2(1H)-one (VUF 10214, 57) and 2-benzyl-3-(4-methyl-piperazin-l-yl) quinoxaline (VUF 10148, 20) as potent H4R ligands with nanomolar affinities. In vivo studies in the rat reveal that compound 57 has significant anti-inflammatory properties in the carrageenan-induced paw-edema model.

From bifunctional nucleophilic behavior of DBU to a new heterocyclic fluorescent platform

(Chemical Equation Presented) An unexpected discovery of a novel cyclocondensation reaction of 1,8-diazabicyclo[5.4.0]undec-8-ene (DBU) with activated 1,2-dichloro compounds is described. The 2-aminopyrrole skeleton is generated through the concomitant formation of new nitrogen-carbon and carbon-carbon bonds. A new pentacyclic derivative formed upon the reaction of 2,3-dichloroquinoxaline with DBU exhibits strong fluorescence both in solutions (Phi in hexane = 0.4) and in the solid state.

THE ALKYLATION OF QUINOXALINO<2,3-b><1,4>BENZOTHIAZINES UNDER PHASE-TRANSFER CATALYSIS CONDITIONS

Quinoxalino<2,3-b><1,4>benzothiazine (mainly in the 12H form) has been alkylated using the phase-transfer catalysis technique.Two N-alkylated isomers, 1x and 2x (in 7:3 ratio), are obtained.Similarly, its chloro derivative present in the 12H form as 8-(3a) and 9-chloro (5a) isomers in 1:1 ratio has been alkylated.Each isomer affords the corresponding pair of N-alkylated isomers.In some cases, these isomers or isomer mixtures could be separated by preparative TLC; they have been identified by UV and 1H-NMR spectroscopy and their ratios determined using photodensitometric and fluorimetric methods.

Synthesis of molecular-gripper-type dynamic receptors and STM-imaging of self-assembled monolayers on gold

Dynamic receptors capable of undergoing large temperature or pH-dependent conformational changes were functionalised with dialkyl thioether legs and adsorbed on Au(111) single crystal surfaces to give self-assembled monolayers (SAMs). The SAMs were characterised by ellipsometry and contact angle measurements. Imaging by scanning tunnelling microscopy (STM) revealed well-ordered monolayers at molecular resolution.

1,2,3-Triazoles based 3-substituted 2-thioquinoxalines: Synthesis, anti-bacterial activities, and molecular docking studies

New 1,2,3-triazoles based on 3-Substituted 2-thioquinoxalines were synthesized via a copper-catalyzed click reaction. The new 1,2,3-triazoles were screened for their in vitro antibacterial activities and were subjected to molecular docking studies. The starting materials included, 3-substituted-2-propargylthioquinoxalines were prepared from 2,3-dichloroquinoxaline, aliphatic amines, sodium sulfide, and propargyl bromide. The click of 2-propargythioquinoxalines with aryl azides catalyzed by copper(II) salen complex afforded novel 1,2,3-triazole-linked thioquinoxalines derivatives. The use of salen copper(II) complex as a catalyst, increased the reaction rate and reduced the loading of the toxic copper species. Results obtained from the in vitro anti-bacterial activities of the synthesized compounds revealed that compounds 7e, 7g, and 7k are active against Bacillus subtilis and Micrococcus luteus bacteria. Furthermore, in silico molecular docking results stipulated a sign of good correlation between experimental activity and calculated binding affinity. Docking studies proved 7e as the most potent compound. In addition, the binding maps exhibited activities that may attribute to the existence of electron donating and lipophilic group at para position of phenyl ring and hydrophobic interactions and hydrogen bond with the protein active sites.
