Some novel benzimidazole derivatives carrying thiosemicarbazide and triazole moieties at the N1 position were synthesized and their in vitro effects on rat liver microsomal NADPH-dependent lipid peroxidation (LP) levels determined by measuring the formation of 2-thiobarbituric acid reactive substance. The free radical scavenging properties of the compounds were also examined in vitro by determining the capacity to scavenge superoxide anion formation and the interaction with the stable free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH). The compounds showed a significant effect in the above tests except to scavenge superoxide anion formation.

Camel Forensic Laboratory, Central Veterinary Research Laboratory, Dubai, UAE.
Rationale: The use of benzimidazole-class novel psychoactive substances has significantly increased worldwide raising concerns about potential misuse and doping in animal sports such as camel racing. Understanding the metabolism of these substances is critical for developing reliable detection methods to ensure fair competition and animal welfare.
Methods: In vitro studies were conducted using homogenized camel liver samples to replicate metabolic processes.

A new series of benzo[h]quinoline-containing heterocycles was synthesized via reactions of benzo[h]quinolinyl-2(3H)-furanone with some nitrogen bidentate nucleophiles, leading to the formation of pyridazinone, pyrrolinone, benzimidazole, and benzoxazinone derivatives. The synthesized compounds were evaluated for their insecticidal activity against Culex pipiens L. larvae.

The formation of the pyroglutamate variant of amyloid beta (pGlu-Aβ), which is extremely hydrophobic, rapidly aggregating, and highly neurotoxic, is mediated by the action of secretory glutaminyl cyclase (sQC). The pGlu-Aβ often acts as a seed for the aggregation of the full length Aβ and contributes to the overall load of Aβ plaques in Alzheimer's disease (AD). Therefore, inhibiting sQC is a potential approach to limit the formation of pGlu-Aβ and to modify the progression of AD.

Background: Cystic echinococcosis (CE) is a common neglected parasitic disease. Nanoparticles containing drugs have been widely utilized in various formulations for several purposes, including improving the bioavailability of drugs by increasing the solubility and dissolution rate of the nanoparticles. The purpose of this study was to evaluate the effects of solid lipid nanoparticles containing albendazole and conjugated to albumin (B-SLN + ABZ) as a novel treatment approach for hydatid cysts in vivo.

In the pursuit of developing potent α-glucosidase inhibitors for managing diabetes, a series of novel benzimidazole-acrylonitrile-1,2,3-triazole derivatives were designed. Sixteen derivatives (12a-p) were synthesized by varying substituents on the phenyl ring of the N-phenylacetamide moiety. Among these, compound 12m emerged as highly effective against α-glucosidase, displaying an IC value of 6.
