Lack of Short-term Memory Improvement in Caenorhabditis elegans after Petunidin-3-glucoside Supplementation

Journal of Preventive, Diagnostic and Treatment Strategies in Medicine, 2023
BACKGROUND:Learning and memory can be enhanced by antioxidants by protecting the neurons against oxidative damage. Phytochemicals, like anthocyanins, may hold the potential to improve cognitive function by ameliorating neuronal damage induced by reactive oxygen species. Petunidin-3-glucoside (P3G) is one of the different classes of anthocyanin found in

The antioxidant activity and active sites of delphinidin and petunidin measured by DFT, in vitro chemical‐based and cell‐based assays

Journal of Food Biochemistry, 2019
A computational DFT B3LYP method with 6-311G (d,p) basis set, the in vitro chemical-based and cellular antioxidant activity (CAA) assays were applied in this study to explain the structure-antioxidant activity relationships of delphinidin and petunidin.

Synthesis of malvidin and petunidin in pigmented tissue cultures ofPetunia hybrida

Protoplasma, 1981
In petunia cells culturedin vitro anthocyanin synthesis is usually repressed resulting in white/ yellow cells. However, we observed that in petunia strain AK-5000 purple cells appeared at a frequency of about 5 × 10−5. Analysis of the pigments showed that these cells contained the same anthocyanidins (petunidin and malvidin) as found in corollas of the

Petunidin suppresses Hashimoto’s thyroiditis by regulating Th1/Th17 homeostasis and oxidative stress

Cellular Immunology
Hashimoto's thyroiditis (HT) is a prevalent autoimmune thyroid disease, necessitating further research to identify effective treatment strategies. Two key pathophysiological factors of HT are inflammation and oxidative stress. Petunidin (PET) is an anthocyanin with anti-inflammatory and antioxidant properties. This study aimed to investigate the effect

Synthesis and Properties of 5,7-dimethylated anthocyanins: Focusing on peonidin-3-O-glucoside and petunidin-3-O-glucoside

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.

Optimized Synthesis and Antioxidant Activity of Anthocyanins Delphinidin-3-O-glucoside and Petunidin-3-O-glucoside

Journal of Agricultural and Food Chemistry
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

Petunidin 3-O-α-Rhamnopyranoside-5-O-β-glucopyranoside and Other Anthocyanins from Flowers of Vicia villosa

Journal of Agricultural and Food Chemistry, 1998
Three anthocyanins were isolated from the acidified methanolic extract of blue flowers of Vicia villosa Roth (hairy vetch) by a combination of ion-exchange resin and gel filtration.

Petunidin attenuates vinclozolin instigated testicular toxicity in albino rats via regulating TLR4/MyD88/TRAF6 and Nrf-2/Keap-1 pathway: A pharmacodynamic and molecular simulation approach

International Immunopharmacology
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 ...
