Food Chemistry
This study developed an efficient chemical synthesis method for 5,7-dimethylated anthocyanins (Pn3GdM and Pt3GdM) to improve the poor liposolubility and instability of anthocyanins. The synthesis involved selective methylation of the A ring using a total synthesis approach and methoxy protection mediated by dimethyl sulfate.

The chemical synthesis of anthocyanins, especially delphinidin-3-O-glucoside and petunidin-3-O-glucoside, is preferable due to the challenges associated with their extraction and purification. However, the reported methods for the synthesis are scarce and intricate. Our research focused on exploring a one-step ester-to-ketone process and optimizing the

Vinclozolin (VZN) is a widely used fungicide which exerts deleterious impacts on various organs including testis. Petunidin (PDN) is a polyphenolic compound that demonstrates a broad range of pharmacological activities. Thirty-two rats were divided into 4 groups including the control, VZN (100 mg/kg), VZN (100 mg/kg) + PDN (4 mg/kg) and PDN (4 mg/kg ...

Background: Alzheimer's disease (AD) is a progressive neurodegenerative disorder marked by memory loss and cognitive decline, where microglia activation triggers neuroinflammation, leading to neuronal damage. Shifting microglia polarization toward an anti-inflammatory phenotype may slow AD progression.
