The design, synthesis and assessment of beta-carboline core-based compounds as potential multifunctional agents against several processes that are believed to play a significant role in Alzheimer's disease (AD) pathology, are described. The activity of the compounds was determined in Abeta self-assembly (fibril and oligomer formation) and cholinesterase (AChE, BuChE) activity inhibition, and their antioxidant properties were also assessed. To obtain insight into the mode of action of the compounds, HR-MS studies were carried out on the inhibitor-Abeta complex formation and molecular docking was performed on inhibitor-BuChE interactions. While several compounds exhibited strong activities in individual assays, compound 14 emerged as a promising multi-target lead for the further structure-activity relationship studies.
