Prevalence to the various biological activities of imidazo[4,5-b] pyridine nucleus has promoted us for an attempt of one pot synthesis of (1H, 3H) imidazo [4,5-b] pyridines (desazopurines) as inhibitors of Lumazine synthase in M. tuberculosis (PDB 2C92). Major advantage of Lumazine synthase enzyme behind consideration as target protein in docking study is its absence in mammalian cell but prese...

A fundamental structural feature of benzimidazoles, a group heterocyclic, aromatic compounds, is the fusion six-membered benzene ring with five-membered imidazole moiety. Formic acid, Acetyl chloride, hydrazine hydrate, Benzene-1,2-diol, Glycolic Acid, Benzoyl Methyl Ethyl Benzamide, and other chemicals were utilized in this research study. In study different methods used such as TLC, IR spectr...

In this study, a class of bis-1,2-(4-aryl-2-alkyl-1H- inden-1-yl) ethane was synthesized and characterized by spectroscopic methods such as 1HNMR, 13CNMR, melting point and FTIR. bis-1,2-(4-aryl-2-alkyl-1H- inden-1-yl) ethane was synthesized by the reaction of butyl­lithium, arylindenes and dibromoethane in a facile, one-pot strategy. It’s shown that these methods have a wide scope to afford li...

In an effort to develop new potent antimicrobial and anticancer agents, new pyrrole-based chalcones were designed and synthesized via the base-catalyzed Claisen-Schmidt condensation of 2-acetyl-1-methylpyrrole with 5-(aryl)furfural derivatives. The compounds were evaluated for their in vitro antimicrobial effects on pathogenic bacteria and Candida species using microdilution and ATP luminescenc...

Reaction between aromatic aldehydes and 3–methyl-1-phenyl-2-pyrazoline-5-one catalyzed by nano-SiO2/HClO4 in water under reflux provided a simple and efficient route for the synthesis of 4-((5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)(aryl)methyl)-3-methyl-1-phenyl-1H-pyrazol-5-ol derivatives in high yields.

The conceptually construction of axially chiral indolostilbenesi.eN-(2-{(E)-2-[2'-(1-Acetyl-1H-indol-2-yl)-3'chloro4,4',6,6'-tetramethoxy[1,1'-biphenyl]-2yl]ethenyl}phenyl)acetamide and N-(2-{(E)-2-[2'-(1-Acetyl-1H-indol-2-yl)-3'-chloro-2,4',6,6'tetramethoxy[1,1'-biphenyl]-4-yl]ethenyl}phenyl) acetamide are described in this paper. These structure, were obtained by the tactical combination of p...

Ethyl (3-methyl-7-substituted-2-oxoquinoxalin-1(2H)-yl) acetates 2a-c are prepared by the condensation of ethyl chloroacetate with 3-methyl-7-substituted quinoxalin-2(1H)-ones 1a-c. The reaction of 2a-c with hydrazine hydrate furnished 2-(3-methyl-7-substituted-2-oxoquinoxalin-1(2H)-yl) acetohydrazides 3a-c, which on cyclisation with substituted aromatic carboxylic acids in the presence of phos...

The centrosymmetric mol-ecule of the title compound, [Zn(C(16)H(11)N(6))(2)(H(2)O)(2)], contains one Zn(2+) ion located on a center of symmetry, two 3-[4-(1H-imidazol-1-yl)phen-yl]-5-(pyridin-2-yl)-1H-1,2,4-triazol-1-ide (Ippyt) ligands and two coordinating water mol-ecules. The Zn(II) ion is six-coordinated in a distorted octa-hedral coordination geometry by four N atoms from two Ippyt ligands...

Abstract Pure-organic red exciplex emitters are far from satisfactory in terms of quantity and efficiency. The narrow lowest unoccupied molecular orbital (LUMO) energy levels range reported acceptors together with the intrinsic exciton non-radiative decay dominant factors restricting progress exciplexes. Herein, two acceptor molecules operating at unique LUMO -3.51 -3.56 eV, namely 4-(6-([1, 1’...

In this study we report the synthesis of a series 2-Azetidinones from N-(4-(5-bromothiophen-2-yl)-6-(4-chlorophenyl)pyrimidin-2- yl)-1-(aryl) methanimine. A mixture methanimine and triethyl amine was reacted with chloroacetyl chloride in 1,4-dioxane. The N-(4-(5-bromothiophen-2-yl)-6-(4 -chlorophenyl) pyrimidin-2- prepared reaction 4-(5-bromothiophene-2-yl)-6-(4-chloropheneyl)pyrimidin-2-amine ...
