Zinc and syringic acid have metabolic and antioxidant medicinal potentials. A novel zinc(II)-syringic acid complex with improved anti-hyperglycaemic and antioxidant potential was developed. Zinc(II) was complexed with syringic acid in a 1:2 molar ratio and characterized using FT-IR, H NMR and LC-MS.

Natural supplements are important in diabetes and oxidative stress management. A complexation-mediated antihyperglycemic and antioxidant synergism between zinc(II) and p-coumaric acid was investigated. p-Coumaric acid was complexed with ZnSO and characterized by FT-IR, H NMR, and mass spectroscopy.

Aim: This study was done to investigate the anti-diabetic and anti-oxidative synergism between zinc(II) and ferulic acid through complexation.

Methods: Zinc sulphate was complexed with ferulic acid in a 1:2 molar ratio. The complex was characterized using Fourier-transform infrared spectroscopy, proton NMR and high-resolution mass spectroscopy techniques and evaluated for cellular toxicity.

Zinc has gained notable attention in the development of potent anti-diabetic agents, due to its role in insulin storage and secretion, as well as its reported insulin mimetic properties. Consequently, zinc(II) has been complexed with numerous organic ligands as an adjuvant to develop anti-diabetic agents with improved and/or broader scope of pharmacological properties. This review focuses on the research advances thus far to identify the major scientific gaps and prospects.
