A series of 4-amino-6-benzimidazole-pyrimidines was designed to target lymphocyte-specific tyrosine kinase (Lck), a member of the Src kinase family. Highly efficient parallel syntheses were devised to prepare analogues for SAR studies. A number of these 4-amino-6-benzimidazole-pyrimidines exhibited single-digit nanomolar IC(50)s against Lck in biochemical and cellular assays. These 4-amino-6-be...

A simple, fast, efficient and environmentally friendly method for synthesis of benzimidazole and its 2-alkyl, aryl and heteroaryl substituted derivatives was developed using zeolite HY. Two component cyclolcondensation of 1,2-phenylenediamine (o-phenylenediamine) and commercially available carboxylic acids catalyzed by zeolite HY without any solvent, under microwave irradiation led to formation...

In the title compound, [CdBr2(C8H8N2)2], the Cd(II) atom has a distorted tetra-hedral coordination formed by the two imino N atoms of two 2-methyl-benzimidazole ligands and two terminal bromide ligands. The Cd(II) atom is slightly out of the benzimidazole planes by 0.320 (3) and 0.210 (3) Å. The dihedral angle between the benzimidazole planes is 71.6 (2)°. In the crystal, mol-ecules are linked ...

Six impurities in pantoprazole sodium bulk drug substance were detected by a simple high performance liquid chromatographic method (HPLC) whose area percentage ranged from approximately 0.05 to 0.34%. Liquid chromatography-mass spectrometry (LC-MS) was performed to identify the molecular weight of the impurities. A thorough study was undertaken to characterize these impurities. These impurities...

In this report, β-tubulin gene polymorphism was investigated in Haemonchus contortus  populations isolated from sheep flocks in different regions of Khouzestan province, southwestern Iran. The samples were chosen on the basis of regional variation in benzimidazole treatment background of sheep flocks. Our objective was to study the relationship between treatment background andβ -tubulin gene po...

Benzimidazole rings are the most important nitrogen-containing heterocycles, which are widely explored and utilized by the pharmaceutical industry for drug discovery. Due to their special structural features and electron-rich environment, Benzimidazole containing drugs bind to a variety of therapeutic targets, thereby exhibiting a broad spectrum of bioactivities. Numerous benzimidazole based dr...

Benzimidazole is a bicyclic heterocyclic aromatic compound in which benzene fused to imidazole moiety. holds vital role the field of medicinal chemistry possesses wide variety pharmacological activities like antibacterial, anti cancer, antifungal, antileishmanial, tubercular, viral and malarial respectively, hence benzimidazole moiety attracting chemist synthesize different derivatives with act...

The mol-ecule of the title compound, C(31)H(29)N(3), contains a hexyl chain, a coordination unit (benzimidazole) and a functional group (carbazole). The benzimidazole ring is not coplanar with either the phenyl ring or the carbazole system, making dihedral angles of 43.26 (3) and 39.03 (2)°, respectively. The dihedral angle between the phenyl ring and the carbazole system is 24.42 (3)°. The hex...

The title compound, 0.759C(19)H(21)ClN(2)O(2)S·0.241C(19)H(21)ClN(2)O(2)S, was synthesized by aryl-sulfonyl-ation of 2-n-butyl-5-chloro-1H-benzimidazole in the presence of triethyl-amine. The crystal structure is composed of two mol-ecules, 2-n-butyl-6-chloro-1-(2,4-dimethylphenyl-sulfon-yl)-1H-benzimidazole and 1-(2,4-dimethylphenyl-sulfon-yl)-2-n-butyl-5-chloro-1H-benz-imidazole, in the refin...
