A novel series of hybrid molecules were designed and synthesized by fusing the pharmacophoric features of cholinesterase inhibitor donepezil and diarylthiazole as potential multitarget-directed ligands for the treatment of Alzheimer's disease (AD). The compounds showed significant in vitro anticholinesterase (anti-ChE) activity, the most potent compound (44) among them showing the highest activity (IC50 value of 0.30 ± 0.01 μM) for AChE and (1.84 ± 0.03 μM) for BuChE. Compound 44 showed mixed inhibition of AChE in the enzyme kinetic studies. Some compounds exhibited moderate to high inhibition of AChE-induced Aβ1-42 aggregation and noticeable in vitro antioxidant and antiapoptotic properties. Compound 44 showed significant in vivo anti-ChE and antioxidant activities. Furthermore, compound 44 demonstrated in vivo neuroprotection by decreasing Aβ1-42-induced toxicity by attenuating abnormal levels of Aβ1-42, p-Tau, cleaved caspase-3, and cleaved PARP proteins. Compound 44 exhibited good oral absorption and was well tolerated up to 2000 mg/kg, po, dose without showing toxic effects.

In this paper, we report the synthesis and cell-based anti-prion activity of quinacrine analogs derived by replacing the basic alkyl side chain of quinacrine with 4-(4-methylpiperazin-I-yl)phenyl, (1-benzylpiperidin-4-yl) and their structural variants. Several promising analogs were found that have a more favorable anti-prion profile than quinacrine in terms of potency and activity across different prion-infected murine cell models. They also exhibited greater binding affinities for a human prion protein fragment (hPrP121-231) than quinacrine, and had permeabilities on the PAMPA-BBB assay that fall within the range of CNS permeant candidates. When evaluated on bidirectional assays on a Pgp overexpressing cell line, one analog was less susceptible to Pgp efflux activity compared to quinacrine. Taken together, the results point to an important role for the substituted 9-amino side chain attached to the acridine, tetrahydroacridine and quinoline scaffolds. The nature of this side chain influenced cell-based potency, PAMPA permeability and binding affinity to hPrP121-231.
