As part of the synthesis of the benzimidazole derivative heterocyclique system, we are interested in studying the condensation of the o-phenylenediamines with amino-acids such as aspartic acid, serine and histidine. The interest that these present is based mainly on their pharmacological properties. They have, in fact anti-inflammatory, antidepressive, antibacterial and antihistamine properties. On the other hand, it should be noted that 5,6-dimethyl-1-(alpha-D-ribofuranosyl) benzimidazole constitutes part of vitamin B12. Taken together, these results led us to pursue our research in this domain while focusing on new methods of benzimidazolic derivative synthesis. It should be said that the obtaining of these compounds depends on the quantity of the amino-acid. All synthesized products have been characterized by infrared, nuclear magnetic resonance and mass spectrometry.

Nowadays, benzimidazole and its derivatives are widely assembled into multifunctional materials with various properties such as mechanochromism, photochromism, thermochromism and electrochromism. Herein, two novel zinc(II) coordination compounds, [Zn(L)Br]·2HO (1) and [Zn(L)Cl]·2HO (2) (L = tetra(1-benzo[]imidazol-2-yl)ethene), have been constructed one-pot facile synthesis from bis(1-benzo[]imidazol-2-yl)methane (L) and zinc(II) salts. The ligand L with a CC double bond was formed by C-C coupling of two sp-C atoms of L in solvothermal synthesis, which provides a new strategy to generate the conjugation system conveniently.

The oxomolybdenum complexes Mo1, Mo2 and Mo3, which share a common ONO donor ligand backbone but differ in their peripheral substituents, were explored to study their reactivity in organic transformations in water. The ligand backbones of Mo1 and Mo2 were covalently linked to a methyl group and a single hydrophobic -hexadecyl chain an ether linkage, respectively. The complex Mo3 was found to possess two -hexadecyl chains attached to the ligand backbone a common amine-N.

Frustrated Lewis pair chemistry (FLP) occupy a crucial position in nonmetal-mediated catalysis, especially toward activation of inert gas molecules. Yet, one formidable issue of homogeneous FLP catalysts is their instability on preservation and recycling. Here we contribute a general solution that marries the polyhedral oligomeric silsesquioxane (POSS) with a structurally specific frustrated Lewis acid to fabricate porous polymer networks, which can form water-insensitive heterogeneous FLP catalysts upon employing Lewis base substrates.

Mebendazole (MBZ), a benzimidazole anthelmintic and cytoskeleton-disrupting compound, exhibits antitumor properties; however, its action on ovarian cancer (OC) is not clearly understood. This study evaluates the effect of MBZ on OC cell lines OVCAR3 and OAW42, focusing on cell proliferation, migration, invasion, and cancer stemness. The underlying mechanisms, including cytoskeletal disruption, epithelial-mesenchymal transition (EMT), and signaling pathways, were explored.
