A key factor in the success of the MTDLs drug discovery approach is the selection of suitable target proteins. Based on the results of our previous research regarding dual-target inhibitors of AChE/GSK-3β and analysis of target proteins, in the current study, 28 hybrids were designed and synthesized. Docking studies allowed us to rationalize the binding mode of the synthesized compounds in both targets. In vitro enzyme inhibition studies identified compound GT15 as a lead molecule with preferential AChE/GSK-3β inhibition (hAChE IC50 = 1.2 ± 0.1 nM; hGSK-3β IC50 = 22.2 ± 1.4 nM). In addition, GT15 showed high kinase selectivity for GSK-3, except for DYRK1, with inhibition rate of 83.69% and 67.94% against DYRK1α and DYRK1β at a concentration of 20 μM. The compound also exhibited good permeability across the blood-brain-barrier and ability to inhibit the phosphorylation of tau protein. Upon oral administration, GT15 exhibited promising cognitive improvement in the scopolamine-induced cognitive deficit mice in the Morris water maze model. These results suggest that AChE and GSK-3 based multitargeted approach have therapeutic potential for Alzheimer's disease.

Synthesis and pharmacological evaluation of a series of 4-quinolylazide derivatives are reported. These were screened against P388 lymphocitic leukemia in mice, but they resulted inactive. All the compounds were also tested for their antimicrobial activity against gram-positive, gram-negative strains and fungi; only three derivatives exhibited poor activity.
