## TL;DR

Oxyphenbutazone may help improve memory and learning in neurotoxic conditions by reducing inflammation and oxidative stress.

## Contribution

This study demonstrates Oxyphenbutazone's therapeutic potential in neurotoxicity via TGF-β/NF-κB/IκB-α pathways using both in silico and in vivo methods.

## Key findings

- OPB treatment improved cognitive performance in LPS-induced neurotoxicity in rats.
- OPB restored levels of proinflammatory cytokines, antioxidants, and key signaling molecules like NF-κB and IκB-α.
- In silico simulations showed stable interactions between OPB and target molecules.

## Abstract

Neuroinflammation and oxidative stress play key roles in cognitive decline and memory impairments. This study employed a lipopolysaccharide (LPS)-induced neurotoxicity model and in silico methods, including in silico docking and dynamic simulations, to assess the therapeutic potential of Oxyphenbutazone (OPB).

Wistar rats were categorized as control, LPS-only section, LPS + OPB receiving low (35 mg/kg) and high (70 mg/kg) doses of OPB, and only OPB (70 mg/kg) doses. Behavioral assessments (Y-maze and Morris water tests) were used to assess cognitive ability. The levels of neuroinflammatory markers [Interleukin-6 (IL-6), IL-1β, and tumor necrosis factor-alpha (TNF-α)] and oxidative stress modulators [Superoxide dismutase (SOD), glutathione (GSH), catalase (CAT), and malondialdehyde (MDA)] were estimated. Additionally, transforming growth factor-beta (TGF-β), nuclear factor-kappa B (NF-κB), and inhibitor of kappa B-alpha (IκB-α) levels were evaluated. In silico analyses, such as molecular docking and dynamic simulations, were used to evaluate the stability of OPB and target molecules.

Cognitive performance improved after OPB treatment, and the levels of proinflammatory cytokines, antioxidants, TGF-β, NF-κB, and IκB-α were restored. Additionally, in silico analyses illustrated favorable and stable interactions between OPB and the target molecules NF-κB and IκB-α.

These findings suggest the therapeutic potential of OPB in mitigating neurotoxicity and the associated cognitive disabilities.
