A Review of the Synthesis and Biological Activity of Flavonoid Mannich Base Derivatives

Abstract

Over the past twenty years (1998–2023), extensive research has focused on the synthesis and biological activity of Mannich base derivatives of flavonoids (FMBD), which have demonstrated exceptional properties towards organic and bioorganic molecules. Several research groups have reported the pharmacological potential of these flavonoid derivatives, including antioxidant and antiviral activities, as well as their ability to inhibit AChE and exhibit anticancer properties. Moreover, the unique characteristic of forming stable complexes with biomolecules positions flavonoid derivatives as valuable assets in the realm of biology and drug discovery. In this extensive review, we′ve meticulously analyzed over seventy six distinct research studies on this subject. Our aim is to provide a succinct overview of the wide‐ranging applications of flavonoid derivatives coupled with amines. Furthermore, we explore the promising horizons and potential innovations in this field. It's essential to highlight that these derivatives display no discernible signs of toxicity or eliciting immune responses, making them even more attractive for biopharmaceutical applications. Undoubtedly, the utilization of flavonoid derivatives combined with amines as crucial biopharmaceutical agents is poised for significant expansion in the forthcoming years.
