The title compound, C(17)H(15)N(2)O(2) (+)·Cl(-)·H(2)O, was synthesized from benzimidazole and furfryl chloride in dimethyl-formamide. The cationic benzimidazolium ring is connected to two furan rings via methyl-ene bridges. The furan rings make dihedral angle of 79.09 (18)° with respect to each other, and make dihedral angles of 73.92 (12) and 72.58 (13)° with respect to the benzimidazole ring...

Two closely related binding modes have previously been proposed for the ATP-competitive benzimidazole class of checkpoint kinase 2 (CHK2) inhibitors; however, neither binding mode is entirely consistent with the reported SAR. Unconstrained rigid docking of benzimidazole ligands into representative CHK2 protein crystal structures reveals an alternative binding mode involving a water-mediated int...

The title mol-ecular salt, C13H11N2O(+)·Cl(-)·H2O, crystallizes as a monohydrate. In the cation, the phenol and benzimidazole rings are almost coplanar, making a dihedral angle of 3.18 (4)°. The chloride anion and benzimidazole cation are linked by two N(+)-H⋯Cl(-) hydrogen bonds, forming chains propagating along [010]. These chains are linked through O-H⋯Cl hydrogen bonds involving the water m...

Crystals of the title compound, 2C(26)H(18)N(4)O(2)·C(7)H(8), were obtained from the reaction of 8-hydroxy-quinoline with 1,2-phenyl-enediamine in methanol and recrystallized from toluene. The compound contains three essentially planar ring systems: the benzimidazole ring (r.m.s. deviation = 0.039 Å) and two 8-hydroxy-quinoline rings (r.m.s. deviations of 0.0056 Å in both rings). The benzimidaz...

In the title complex, [Mn(C(9)H(4)N(2)O(4))(H(2)O)(2)](n), the Mn(II) atom is in a distorted octa-hedral coordination completed by one N atom from one 1H-benzimidazole-5,6-dicarboxyl-ate ligand, two O atoms from two different 1H-benzimidazole-5,6-dicarboxyl-ate ligands, and three O atoms from three water mol-ecules. Two bridging water mol-ecules and two bridging carboxyl-ate groups from a 1H-be...

Benzyl-o-vanillin and benzimidazole nucleus serve as important pharmacophore in drug discovery. The benzyl vanillin (2-(benzyloxy)-3-methoxybenzaldehyde) compound shows anti-proliferative activity in HL60 leukemia cancer cells and can effect cell cycle progression at G2/M phase. Its apoptosis activity was due to disruption of mitochondrial functioning. In this study, we have studied a series of...

The reaction of 1H-benzimidazole-5-carb-oxy-lic acid with silver nitrate in the presence of perchloric acid under hydro-thermal conditions yielded the title complex, [Ag(C(8)H(6)N(2)O(2))(2)]ClO(4), which comprises of an [Ag(C(8)H(6)N(2)O(2))(2)] mononuclear cation and a perchlorate anion. The Ag(I) ion is coordinated by two N atoms from two different neutral 1H-benzimidazole-5-carb-oxy-lic aci...

The crystal structure of human chymase complexed with a novel benzimidazole inhibitor, TJK002, was determined at 2.8 Å resolution. The X-ray crystallographic study shows that the benzimidazole inhibitor forms a non-covalent interaction with the catalytic domain of human chymase. The hydrophobic fragment of the inhibitor occupies the S1 pocket. The carboxylic acid group of the inhibitor forms hy...

Although a number of antiviral drugs inhibit replication of Epstein-Barr virus (EBV) in cell culture, and acyclovir (ACV) suppresses replication in vivo, currently available drugs have not proven effective for treatment of EBV-associated diseases other than oral hairy leukoplakia. Benzimidazole riboside compounds represent a new class of antiviral compounds that are potent inhibitors of human c...

A series of 1-(1H-benzimidazol-2-yl)-3-(substituted)-2-propen-1-one and its 1-methyl analogues 2c-h were synthesized and cyclized with different reagents such as ethyl cyanoacetate, thiourea, hydroxylamine hydrochloride, guanidinium sulfate, methylhydrazine, phenylhydrazine and/or hydrogen peroxide in different reactions to produce pyridones 3a,b, pyrimidinethione 4a,b, isoxazole 5a,b, aminopyr...
