Determination of the inhibition profiles of pyrazolyl-thiazole derivatives against aldose reductase and α-glycosidase and molecular docking studies.

Aldose reductase (AR) is the first and rate-limiting enzyme of the polyol pathway, which converts glucose to sorbitol in an NADPH-dependent reaction. α-Glycosidase breaks down starch and disaccharides to glucose. Hence, inhibition of these enzymes can be regarded a considerable approach in the treatment of diabetic complications.

Moringa Oleifera: A Review of Its Occurrence, Pharmacological Importance and Oxidative Stress.

Oxidative/nitrosative stress can be caused by excessive production of ROS and RNS with metabolic reactions that change the balance in favor of oxidants in cases where oxidants increase and antioxidants decrease in organisms using oxygen. ROS and RNS react with several biological macromolecules in cells, such as carbohydrates, nucleic acids, lipids, and proteins, and alter their functions. Some natural antioxidants are constantly being researched for their benefits in terms of human health, which can strengthen the body's antioxidant defense system and have the potential to scavenger free radicals.
