A visible light-responsive magnetically separable photocatalyst Pd-g-CN-Vanillin@γ-FeO-TiO is fabricated using vanillin as a natural junction under ultrasonic agitation. Structural, morphological, optical, thermal, and magnetic assessments of the as-prepared catalyst are carried out. The photocatalyst successfully drives the simultaneous benzimidazole formation, and olefin hydrogenation with high atom economy under blue LED light and mild conditions. The photocatalytic activity of Pd-g-CN-Vanillin@γ-FeO-TiO is significantly affected by the γ-FeO:TiO weight ratio. PL spectra revealed the effective separation of carriers in the fabricated catalyst promoting its photocatalytic activity. The action spectra using the apparent quantum efficiency (AQE) exhibited the maximum AQEs at 520 and 750 nm in which the highest performance for styrene hydrogenation is observed. The title magnetically separable heterogeneous photocatalyst provides high yields of products under perfectly safe visible light, produces low/zero waste, and avoids using an external high-pressure hydrogen gas source, harmful solvents, undesirable additives, and reducing agents rendering green conditions for chemical reactions.

This study synthesizes a novel three-dimensional (3D) porous coordination polymer (CP), {[Co(L)₀.₅(H₂O)]·NMP·H₂O} (1), via a solvothermal method in a mixed solvent of water and NMP (1-methyl-2-pyrrolidinone), reacting Co(II) ions with H₄L (1,4-bis(5,6-carboxybenzimidazolylmethyl)benzene). The CP exhibits unique fluorescence properties, emitting at 420 nm under UV light excitation at 350 nm, and serves as a carrier for Mesalazine (MSZ) in therapeutic applications.

Background: α-Glucosidase inhibitors play an important role in the treatment of type 2 diabetes mellitus. Inhibitors of the latter enzyme that are available on the market created gastrointestinal side effects and achieve to a high potent and low side effect potent α-glucosidase inhibitors is a valuable target for medicinal chemists.
Objective: In this study, derivatives of benzimidazole-phenoxy-1,2,3-triazole-benzyl skeleton were introduced as new α-glucosidase inhibitors.

This study focuses on the design, synthesis, and evaluation of benzimidazole derivatives for their anti-tumor activity against A549 and PC-3 cells. Initial screening using the MTT assay identified compound 5m as the most potent inhibitor of A549 cells with an IC of 7.19 μM, which was superior to the positive agents 5-Fluorouracil and Gefitinib.

The efficacy of cancer immunotherapy relies on a sufficient amount of functional immune cells. Triple-negative breast cancer lacks enough immune cell infiltration, and adjuvant therapy is necessary to prime anti-tumor immunity. However, the improvement in efficacy is unsatisfactory with concern about inducing systemic immunotoxicity.

In this work, we have explored the metal ion sensing properties of two bisbenzimidazole-based fluorescent probes, that differ in their conformational flexibility, in an aqueous medium. The compound with a flexible methyl spacer (1) experienced blue shifts in its absorption and emission maxima (along with a turn-off response) upon the addition of Hg ions. On the contrary, the compound with a relatively rigid structure (2) showed red shifts in both its absorption and emission maxima (along with a turn-off response) when treated with Hg under similar conditions.
