Resveratrol and Its Derivatives Diminish Lipid Accumulation in Adipocytes In Vitro-Mechanism of Action and Structure-Activity Relationship.

Background And Objectives: Expansion of white adipose tissue causes systemic inflammation and increased risk of metabolic diseases due to its endocrine function. Resveratrol was suggested to be able to prevent obesity-related disorders by mimicking caloric restriction; however, its structure-activity relationships and molecular targets are still unknown. We aimed to compare the effects of resveratrol and its analogues on adipocyte metabolism and lipid accumulation in vitro.

Differential Cytoprotective Effect of Resveratrol and Its Derivatives: Focus on Antioxidant and Autophagy-Inducing Effects.

Numerous beneficial effects of resveratrol were reported; however, its pharmacological profile is contradictious. Previously, we have demonstrated that resveratrol has a dose-dependent cytoprotective effect and the essential role of autophagy induction was demonstrated. Resveratrol suffers from unfavorable pharmacokinetics, hindering its clinical use.

Glycine Transporter 1 Inhibitors Minimize the Analgesic Tolerance to Morphine.

Opioid analgesic tolerance (OAT), among other central side effects, limits opioids' indispensable clinical use for managing chronic pain. Therefore, there is an existing unmet medical need to prevent OAT. Extrasynaptic N-methyl D-aspartate receptors (NMDARs) containing GluN2B subunit blockers delay OAT, indicating the involvement of glutamate in OAT.

Separation of tolperisone and its degradation products by a dual cyclodextrin capillary electrophoresis system to study their potential role in allergic events.

Tolperisone is a centrally acting muscle relaxant that has been used for the treatment of post-stroke spasticity and low back pain. Recently, the safety of tolperisone pharmaceutical products has been reassessed due to growing concerns over allergic adverse events. Reactive degradants of tolperisone may be responsible for these hypersensitivity reactions.

Capillary Electrophoresis-Laser Induced Fluorescence Method Development and Validation for Quantification of Nine Gangliosides-Application to Analysis of Cell Lines of CNS Origin.

Gangliosides are sialic acid-containing glycosphingolipids that play an essential role in many biological and pathophysiological processes. They are present in high amounts in the central nervous system and their abnormal metabolism or expression has been observed in many diseases. We have developed and validated a sensitive capillary electrophoresis laser-induced fluorescence (CE-LIF) method for the separation and quantification of oligosaccharides digested from nine gangliosides of high biological relevance.
