The enzyme pteridine reductase 1 (PTR1) is a potential target for new compounds to treat human African trypanosomiasis. A virtual screening campaign for fragments inhibiting PTR1 was carried out. Two novel chemical series were identified containing aminobenzothiazole and aminobenzimidazole scaffolds, respectively. One of the hits (2-amino-6-chloro-benzimidazole) was subjected to crystal structu...

Benzimidazole, which is a heterocyclic nucleus, plays an important role in various medicines. A number of therapeutic agents such as H1 antihistaminic agent clemizole, a potent opioid analgesic etonitazene, nonnucleoside antiviral compound enviroxime, for promotion of excretion of uric acid irtemazole, non sedating antihistaminic agent astemizole, anti ulcer drugs omeprazole and pentoprazole, a...

A class of innovative benzimidazole-1,3,4-Oxadiazole derivatives is a significant heterocyclic molecule for therapeutic development. In chemistry, the novel 1,3,4-Oxadiazole nucleus has wide range uses, including antibacterial, treatment. Molecular docking frequently employed in contemporary drug design to comprehend drug-receptor interaction. Swiss dock, PyRx, and discovery studio visualizer (...

Benzimidazole and its derivatives are used in organic synthesis and they are used in evaluating new product that possesses different biological activities. This review article covers the most active benzimidazole derivatives that have shown considerable biological actions such as antimicrobial, anti-inflammatory, anticancer, anticonvulsant, antidepressant, antioxidant, radioprotective and anti-...

In the title compound, [ZnCl2(C14H12N2)2], the Zn(II) atom exhibits a distorted tetra-hedral coordination geometry involving two chloride anions and two N-atom donors from 1-benzyl-1H-benzimidazole ligands. In both ligands, the benzyl and benzimidazole rings are nearly perpendicular [dihedral angles = 81.7 (2) and 81.5 (2)°]. The two benzimidazole systems are essentially planar [maximum deviati...

Two new molecular structures, namely 1,3-bis(trimethylsilyl)-1H-benzimidazole-2(3H)-thione, C13H22N2SSi2, (2), and 1-trimethylsilyl-1H-benzimidazole-2(3H)-thione, C10H14N2SSi, (3), are reported. Both systems were derived from 1H-benzimidazole-2(3H)-thione. Noncovalent C-H···π interactions between the centroid of the benzmidazole system and the SiMe3 groups form helicoidal arrangements in (2). D...

The title compound, C(24)H(27)N(2)Si(+)·Br(-)·H(2)O, was synthesized from 1-(dimethyl-phenyl-silylmeth-yl)-1H-benzimidazole and (2-bromo-eth-yl)benzene in dimethyl-formamide. The benzimidazole ring system is nearly planar, with a maximum deviation of 0.015 (5) Å, and forms dihedral angles of 73.0 (3) and 39.6 (2)°, with the phenyl rings. In the crystal, mol-ecules are linked by O-H⋯Br, C-H⋯Br a...

Taking orostanal (a compound from a Japanese marine sponge, Stelletta hiwasaensis) as a lead compound, some novel B-norcholesteryl benzimidazole and benzothiazole derivatives were synthesized. The antiproliferative activity of the compounds against human cervical carcinoma (HeLa), human lung carcinoma (A549), human liver carcinoma cells (HEPG2) and normal kidney epithelial cells (HEK293T) was a...

Anionic aromatic ipso-substitution has allowed an aziridine ring to be fused onto pyrrolo[1,2-a]benzimidazole. This diazole analogue of aziridinomitosene, and N-[(aziridinyl)methyl]-1H-benzimidazole are shown to be significantly more cytotoxic towards the human breast cancer cell lines MCF-7 and HCC1937 than towards a human normal fibroblast cell line (GM00637). The aziridinyl fused pyrrolo[1,2...

In the title solvated benzimidazole compound, C(20)H(15)N(3)O(2)·C(2)H(6)OS, both the benzimidazole fused-ring system and the complete dimethyl sulfoxide solvent mol-ecule are disordered over two sets of sites, in 0.750 (5):0.250 (5) and 0.882 (4):0.118 (4) ratios, respectively. The conformation of the pyrimidine ring is close to a half-chair for the major disorder component, whereas for the mi...
