Non-enzymatic glycation and Oxidation of some essential biological macromolecules are paramount in the pathogenesis of various diseases including diabetes and atherosclerosis. Hyperglycemia plays a key role in the pathological process of diabetic complications by progressive accumulation of advanced glycation end products (AGEs) in body tissues. Formation of AGEs as a result of protein glycation is followed by an increased free radical activity that additionally contributes towards the bio-macromolecular damage. The present study aimed to evaluate the free radical scavenging and antiglycation capacity of isoferulic acid (IFA). The free radical scavenging activity of IFA was measured using DPPH, FRAP, and metal chelating assays. IFA showed effective reducing power, free radical scavenging activity and metal chelation activity in concentration dependent manner. The antiglycation activity of IFA was studied using various spectroscopic techniques. The obtained results were validated with free amino, sulfhydryl group, carbonyl content and AGEs formation. Secondary structural alterations were monitored using circular dichroism, morphology of aggregates was analyzed using transmission electron microscopy. Molecular docking reveals the possible binding location of IFA with in the sub-domain IIA of human serum albumin (HSA).

Methylglyoxal (MG) is a reactive precursor to advanced glycation end-products (AGEs), which exert deleterious effects on cells and tissues. MG also causes pancreatic β-cell dysfunction and apoptosis. Isoferulic acid (IFA), a naturally occurring cinnamic acid derivative, is considered to be an antiglycating agent. However, the effect of IFA on MG-induced pancreatic β-cell dysfunction remains unknown. The objective of this study was to determine the protective effect of IFA against MG-induced mitochrondrial dysfunction and apoptosis in INS-1 pancreatic β-cells. The results showed that pretreatment of INS-1 cells with 100 μM IFA for 48 h prevented MG-induced decrease in cell viability and impairment of glucose-stimulated insulin secretion (GSIS). In addition, 100 μM IFA pretreatment also decreased MG-induced generation of reactive oxygen species (ROS) and upregulation of mitochondrial uncoupling protein 2 (Ucp2) mRNA expression. Furthermore, IFA pretreatment reduced MG-induced increase in caspase-3 activity, suggesting a reduction of apoptotic cell death. IFA (50-100 μM) itself markedly increased the activity of glyoxalase 1 (GLO1), a major enzyme for the detoxification of MG. The results showed that 100 μM IFA protected MG-induced loss of GLO1 activity in INS-1 cells. These findings suggest that IFA pretreatment attentuates MG-induced dysfunction and apoptosis in INS-1 pancreatic β-cells through mitochondrial survival pathway and increasing GLO1 activity.

Bioavailability strongly determines polyphenol bioactivity, and is strongly influenced by food matrix, enzymatic and microbial degradation, and gastrointestinal absorption. To avoid human trials for pre-screening of polyphenol bioavailability, studies have focused on in vitro model development. Nevertheless, their predictive value for bioavailability can be questioned.
METHOD AND RESULTS:
We used the orange flavonoid hesperidin 2S to validate a model combining digestion in the simulator of the human intestinal microbial ecosystem (SHIME) and Caco-2 cell transport, with a human intervention study. In vitro, hesperidin was resistant to degradation in the stomach and small intestine, but was rapidly deconjugated on reaching the proximal colon. Extensive and colon-region-specific degradation to smaller phenolics was observed. Hydrocaffeic and dihydroisoferulic acid accumulated in proximal, and hydroferulic acid in distal colon. Caco-2 transport was the highest for dihydroisoferulic acid. In humans, plasma and urine hesperetin-glucuronide levels increased significantly, whereas the impact on small phenolics was limited.
In the combined in vitro model, smaller phenolics strongly accumulated, whereas in humans, hesperetin conjugates were the main bioavailable compounds. Future in vitro model development should focus on simulating faster polyphenol absorption and elimination of smaller phenolics to improve their predictive value of in vivo polyphenol bioavailability.

3-Hydroxy-4-methoxycinnamic acid (Isoferulic acid) is a cinnamic acid derivative that has antidiabetic activity. 3-Hydroxy-4-methoxycinnamic acid binds to and activates α1-adrenergic receptors (IC50=1.4 µM) to enhance secretion of β-endorphin (EC50=52.2 nM) and increase glucose use.
