Oxindole Analogues as Anticancer Agents and their Therapeutic Potential

Oxindole and its derivatives have emerged as interesting scaffolds for developing innovative anticancer medicines due to their various biological activities and capacity to target critical molecular pathways in cancer growth. The oxindole nucleus has powerful anticancer capabilities, which are exerted through various methods, including kinase inhibition, apoptosis induction, disruption of microtubule dynamics, and signaling pathway modification (PI3K/Akt, MAPK, and p53). Furthermore, oxindole-based drugs have been beneficial in combating multidrug resistance and improving the efficacy of existing chemotherapeutic treatments. The current review examines the anticancer potential of the oxindole nucleus, including structure-activity correlations, molecular targets, and methods of action. Furthermore, we discuss current advances in oxindole-derived drug design and its clinical implications, providing insights into prospective therapeutic possibilities. Understanding the molecular characteristics of oxindole derivatives can help in the rational development of new anticancer medicines with higher efficacy and selectivity.
