Objective: The goal of the present study is to examine pretreatment with Schiff bases and derivatives of pregabalin along with their metal (Zn and Cu) complexes on the severity of epilepsy, latency time, duration of convulsions, seizure score and survival rate in mice.

Methods: To achieve the goal, a molecular docking study of analogues was carried out on a specific molecular target, such as the alpha-2δ receptor (PDB ID: 6ND9); which revealed the significant binding affinity of the analogs to their respective target. Based on the docking information, all pregabalin derivatives were synthesized and antiepileptic effect was confirmed by applying the PTZ model that prioritized the most crucial significant points responsible for biological activity.

Results: The test compounds markedly increased the latency of the first seizure and reduced the frequency of seizures throughout the body and frequent spinning and jumps. Additionally, treatment with pregabalin derivatives in mice that received PTZ significantly reduced the duration of seizures and seizure score. However, it increased the survival rate of the mice.

Discussion: Since the newly synthesized compounds were more active as compared to the parent drug in some respects; therefore, the expansion of the project can be planned to explore clinical side of the drugs in the future.

Background: Diabetic peripheral neuropathy (DPN) is a chronic microvascular complication in diabetic mellitus patients due to chronic hyperglycemia, resulting in platelet hyperactivity and dyslipidemia. Alpha-lipoic acid (ALA) is a potent antioxidant which has antiplatelet activity and lipid-modulating characteristics and plays a major role in the prevention of disease progression.

Aim: To evaluate the effect of ALA on inhibition of platelet aggregation and lipid profile.

This research introduced a novel polymer synthesized by combining chitosan and modified polyvinyl alcohol, cross-linked with boric acid using dynamic covalent bonds. The polymer was developed to formulate a pregabalin Film-forming system (FFS) for treating postherpetic neuralgia via topical application, showcasing notable skin adhesion and drug delivery properites. The chitosan-boric acid-modified polyvinyl alcohol polymer was analyzed using NMR, FTIR.

The discovery of epinephrine (adrenaline) and its subsequent implications in medicine owes significant contributions to Cybulski across different centuries, who, in 1894, was pivotal in identifying the adrenal medulla's role in blood pressure regulation and naming the active substance "", known today as adrenaline. His work demonstrated the adrenal glands' critical function in the body's regulatory mechanisms beyond the nervous system. Cybulski's groundbreaking research laid foundational knowledge for future endocrinological studies and pharmaceutical advancements.
