MOLECULES (BASEL, SWITZERLAND) 2022; 27:molecules27196616. [PMID: 36235153 PMCID: PMC9573694 DOI: 10.3390/molecules27196616] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/08/2022] [Revised: 09/30/2022] [Accepted: 10/01/2022] [Indexed: 11/22/2022]
Abstract
Herbal raw materials with antidiabetic activity can be a valuable support to therapy. An optimized extraction process allows for the best possible health-promoting effect. Box-Behnken design was employed to optimize the content of methanol used in the extraction mixture, its time, and temperature. The aim of this study was to enhance the efficiency of the pomegranate flowers extraction process in order to obtain extracts with the highest enzyme inhibition power (α-amylase and α-glucosidase), which is important for the antidiabetic effect and the highest antioxidant activity (DPPH assay). In the Box-Behnken design model, the content of pelargonidin-3,5-glucoside-anthocyanin compound that is associated with antidiabetic activity was also optimized as a variable associated with the action profile of pomegranate flower extracts. The process optimization carried out in this study provides a basis for further research using the pomegranate flower extract with the most potent desired properties, essential for supporting diabetes treatment based on pomegranate flowers.

Food Chem 2022; 372:130892. [PMID: 34607046 DOI: 10.1016/j.foodchem.2021.130892] [Citation(s) in RCA: 19] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2021] [Revised: 08/15/2021] [Accepted: 08/16/2021] [Indexed: 12/24/2022]
Abstract
The effect of protein-phenolic interactions on the functional properties of lentil protein and in vitro gastrointestinal digestibility in different systems (extract solution, protein-phenolic solution, and emulsion) was studied. The presence of phenolic compounds negatively affected the foaming and emulsion properties of lentil protein. During in vitro gastrointestinal digestion, total phenolic content (TPC) and antioxidant capacity of the samples were decreased with the presence of lentil protein at the initial phase, however, they were found to be the highest in emulsions at the intestinal phase. The amount of protocatechuic acid and phenolic acid derivative was increased at the intestinal phase, while that of other phenolic compounds was decreased. Quercetin was not detected at the intestinal phase in all systems, while its glycoside derivatives were determined, which were the highest in emulsions. Anthocyanins were also the highest in extract solution among all systems. Protein-phenolic interactions had a significant effect on functional properties of lentil proteins, and bioaccessibility or antioxidant capacity of phenolic compounds.

Eur J Med Chem 2020; 197:112314. [PMID: 32344181 DOI: 10.1016/j.ejmech.2020.112314] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2020] [Revised: 04/06/2020] [Accepted: 04/06/2020] [Indexed: 02/08/2023]
Abstract
Myocardial infarction (MI) injury is a highly lethal syndrome that has, until recently, suffered from a lack of clinically efficient targeted therapeutics. The cardiac troponin I interacting kinase (TNNI3K) exacerbates ischemia-reperfusion (IR) injury via oxidative stress, thereby promoting cardiomyocyte death. In this current study, we designed and synthesized 35 novel TNNI3K inhibitors with a pyrido[4,5]thieno[2,3-d] pyrimidine scaffold. In vitro results indicated that some of the inhibitors exhibited sub-micromolar TNNI3K inhibitory capacity and good kinase selectivity, as well as cytoprotective activity, in an oxygen-glucose deprivation (OGD) injury cardiomyocyte model. Furthermore, investigation of the mechanism of the representative derivative compound 6o suggested it suppresses pyroptosis and apoptosis in cardiomyocytes by interfering with p38MAPK activation, which was further confirmed in a murine myocardial infarction injury model. In vivo results indicate that compound 6o can markedly reduce myocardial infarction size and alleviate cardiac tissue damage in rats. In brief, our results provide the basis for further development of novel TNNI3K inhibitors for targeted MI therapy.
