Synthesis, biological evaluation and molecular docking study of oxindole based chalcone analogues as potent anti-Alzheimer agents
With the goal of developing potential cholinesterase pharmaco-therapeutics, a new class of thirty analogs oxindole-based chalcone were synthesized by reacting nitro substituted oxindole with various substituted benzaldehyde in the presence of a base in ethanol under reflux conditions. All the synthe...
