An insight into isatin and its hybrid scaffolds as anti-cancer agents: an explicative review

As a bioactive heterocyclic congener, isatin has a wide range of pharmacological and biological uses. Due to their numerous potential uses, it is becoming increasingly important to design inventive isatin and its analogs. Additionally, it is essential to disclose groundbreaking techniques for synthesizing this nucleus, examine the various potencies of that heterocycle, and investigate potential uses for isatin. One significant class of chemotherapeutic medicines with the ability to overcome drug resistance are metal-based medications. The creation of novel therapeutic medications with distinct modes of action is required due to the rise in drug resistance, treatment failures, and the scarcity of available treatments. Such isatin derivatives, which target distinct biomolecules or organelles, demonstrated encouraging antiproliferative capabilities against various cancer cells when they were free ligands or coupled to metal ions. Its biological qualities are typically enhanced when it binds to metal ions, suggesting that the metal and the ligand are modulating each other in a synergistic way. Isatin is a strong inhibitor of numerous enzymes and receptors that can induce apoptosis in a variety of cell lines and affect the expression of specific genes linked to apoptosis. Hybridization is a promising approach to drug discovery because hybrid molecules have the potential to overcome drug resistance, improve specificity, and increase efficiency. Several hybrid compounds are now undergoing various phases of clinical trials. A growing number of experts are interested in studying the chemical and pharmacological properties of isatin-heterocycle hybrids. Anti-cancer activity of isatin scaffolds is reviewed. As lead compounds, several isatin analogues have been created, and their functions assessed. The development of new, powerful therapeutic medications resulting from the combination of isatin with other pharmacophores in a molecule may facilitate the creation of powerful lead compounds.
