Design, synthesis, and biological evaluation of novel xanthone-alkylbenzylamine hybrids as multifunctional agents for the treatment of Alzheimer’s disease
In this study, a series of multifunctional hybrids against Alzheimer’s disease were designed and obtained by conjugating the pharmacophores of xanthone and alkylbenzylamine through the alkyl linker. Biological activity results demonstrated that compound 4j was the most potent and balanced dual ChEs inhibitor with IC50 values 0.85 μM and 0.59 μM for eeAChE and eqBuChE, respectively.

A series of novel 1-hydroxyl-3-aminoalkoxy xanthone derivatives were designed, synthesized and evaluated for in vitro anticancer activity against four selected human cancer cell lines (nasopharyngeal neoplasm CNE, liver cancer BEL-7402, gastric cancer MGC-803, lung adenocarcinoma A549). Most of the synthesized compounds exhibit effective cytotoxic activity against the four tested cancer cell lines with the IC50 values at micromolar concentration level. Some preliminary structure activity relationships were also discussed. In this series of derivatives, compound 3g shows excellent broad spectrum anticancer activity with IC50 values ranging from 3.57 to 20.07 mu M. The in vitro anticancer activity effect and action mechanism of compound 3g on human gastric carcinoma MGC-803 cell were further investigated. The results showed that compound 3g exhibits dose- and time-dependent anticancer effects on MGC-803 cells through apoptosis, which might be associated with its decreasing intracellular calcium and the mitochondrial membrane potential.
