Hesperidin Methyl Chalcone reduces extracellular Aβ peptide aggregation and fibrillation and also protects Neuro 2a cells from Aβ induced neuronal dysfunction.

In the present study, we evaluated the neuroprotective potential of Hesperidin Methyl Chalcone (HMC) against the neurotoxicity induced by Aβ peptide HMC demonstrated higher free-radical scavenging activity than Hesperidin in initial cell-free studies.

New Trends in the Pharmacological Intervention of PPARs in Obesity: Role of Natural and Synthetic Compounds.

Obesity is a major health concern for a growing fraction of the population, as its prevalence and related metabolic disorders are not fully understood. Over the last decade, many attempts have been undertaken to understand the mechanisms at the basis of this condition, in which the accumulation of fat occurring in adipose tissue leads to the pathogenesis of obesity- related disorders. Among the most recent studies, those on Peroxisome Proliferator Activated Receptors (PPARs) revealed that these nuclear receptor proteins acting as transcription factors, among others, regulate the expression of genes involved in energy, lipid, and glucose metabolisms, and chronic inflammation.
