Tolfenamic acid is a nonsteroidal anti-inflammatory drug with neuroprotective properties, and it alleviates learning and memory deficits in the APP transgenic mouse model of Alzheimer's disease. However, whether tolfenamic acid can prevent motor and memory dysfunction in transgenic animal models of Huntington's disease (HD) remains unclear. To this end, tolfenamic acid was orally administered to transgenic R6/1 mice from 10 to 20 weeks of age, followed by several behavioral tests to evaluate motor and memory function. Tolfenamic acid improved motor coordination in R6/1 mice as tested by rotarod, grip strength, and locomotor behavior tests and attenuated memory dysfunction as analyzed using the novel object recognition test and passive avoidance test. Tolfenamic acid decreased the expression of mutant huntingtin in the striatum of 20-week-old R6/1 mice by inhibiting specificity protein 1 expression and enhancing autophagic function. Furthermore, tolfenamic acid exhibited antioxidant effects in both R6/1 mice and PC12 cell models. Collectively, these results suggest that tolfenamic acid has a good therapeutic effect on R6/1 mice, and may be a potentially useful agent in the treatment of HD.

In this paper, we present a green application for the synthesis of novel pyridine derivatives 4a-f via one-pot, multicomponent reaction (MCRs) of some aromatic aldehydes 1a-f with malononitrile (2) and N-(4-acetylphenyl)-4-methylbenzenesulfonamide (3) in the presence of ammonium acetate using ultrasonic irradiation (U.S) in an aqueous solvent HO:EtOH (2:1). The structures of all synthesized pyridines 4a-f were confirmed via elemental analysis and different spectroscopic techniques.

Objective: To assess attitudes of Thai veterinarians towards perioperative pain management in dogs and cats, and explore associations between demographic characteristics and use of analgesics and pain assessment.
Study Design: Paper-based survey distributed in person during various small animal practitioner conferences in 2022.
Methods: The questionnaire encompassed six sections: demographic information, use of analgesic techniques, postoperative pain evaluation, pain indicators, general opinions and confidence in managing postoperative pain in dogs and cats.

Two Ag(I) complexes containing triphenylphosphine and non-steroidal anti-inflammatory drug ligands were synthesized and investigated using various spectroscopic studies and single crystal X-ray crystallography. The binding properties of tolfenamic acid, ibuprofen and the two complexes with DNA and BSA were investigated using UV or fluorescence spectroscopy. The results showed that two Ag(I) complexes bound to DNA by the intercalation mode and interacted with BSA using a static quenching procedure.

1. The objective of this research was to compare the pharmacokinetics and bioavailability of tolfenamic acid, analgesic, antipyretic and anti-inflammatory compound, after administration through different routes to Pekin ducks. The investigation was carried out over four time periods using a randomised cross-pharmacokinetic design.
