• General Description: 1,2,3,4-TETRAHYDRO-9-ACRIDINAMINE (tacrine) and its derivatives exhibit diverse pharmacological activities, including potent antimalarial effects through inhibition of falcipain-2, anticancer properties via telomerase inhibition and p53 pathway activation, and improved acetylcholinesterase (AChE) inhibitory activity with reduced hepatotoxicity for Alzheimer’s disease (AD) treatment. Additionally, tacrine-based hybrids demonstrate multifunctional potential in AD therapy by combining cholinesterase inhibition with antioxidant effects. Its structural versatility allows for synthetic modifications, enabling the development of disubstituted derivatives with enhanced biological activity.
