Alzheimer's disease (AD) is a chronic and progressive neurodegenerative disease, characterized by irreversible cognitive impairment, memory loss and behavioral disturbances, ultimately leading to death. Glycogen synthase kinase 3β (GSK-3β) and dual-specificity tyrosine phosphorylation regulated kinase1A (DYRK1A) have gained a lot of attention for its role in tau pathology. To search for potential dual GSK-3β/DYRK1A inhibitors, we focused on harmine, a natural β-carboline alkaloid, which has been extensively studied for its various biological effects on the prevention of AD. In this study, a new series of harmine derivatives were designed, synthesized and evaluated as dual GSK-3β/DYRK1A inhibitors for their multiple biological activities. The in vitro results indicated that most of them displayed promising activity against GSK-3β and DYRK1A. Among them, compound ZDWX-25 showed potent inhibitory effects on GSK-3β and DYRK1A with IC50 values of 71 and 103 nM, respectively. Molecular modelling and kinetic studies verified that ZDWX-25 could interact with the ATP binding pocket of GSK-3β and DYRK1A. Western blot analysis revealed that ZDWX-25 inhibited hyperphosphorylation of tau protein in okadaic acid (OKA)-induced SH-SY5Y cells. In addition, ZDWX-25 showed good blood-brain barrier penetrability in vitro. More importantly, ZDWX-25 could ameliorate the impaired learning and memory in APP/PS1/Tau transgenic mice. These results indicated that the harmine-based compounds could be served as promising dual-targeted candidates for AD.

New triazine-based tricarboxylic acid linkers were prepared as elongated relatives of triazinetribenzoic acid (TATB). Additionally, functional groups (NO2, NH2, OMe, OH) were introduced for potential post-synthetic modification (PSM) of MOFs. Functionalized tris(4-bromoaryl)triazine "cores" (3a,3b) were obtained by unsymmetric trimerization mixing one equivalent of an acid chloride (OMe or NO2 substituted) with two equivalents of an unsubstituted nitrile. Triple Suzuki coupling of the cores 3 with suitable phenyl- and biphenylboronic acid derivatives provided elongated tricarboxylic acid linkers as carboxylic acids 17 and 20 or their esters 16 and 19. Reduction of the nitro group and cleavage of the methoxy group gave the respective amino and hydroxy-substituted triazine linkers.
