Abstract
- [Display omitted] A novel series of 2-styryl-5-hydroxy-4-pyrone derivatives and analogues were designed and synthesized as H 3 receptor antagonism based multitarget-directed ligands (MTDLs) for AD therapy using pharmacophore-combine strategy. The 2-styryl-5-hydroxy-4-pyrone pharmacophore with metal ion chelation, antioxidation, and A β aggregation inhibition activities was employed as the "eastern part", and a typical phenoxyalkylamine moiety was used as "central ring + western part" of the H 3 receptor antagonist. The biological evaluation revealed that the majority of the target compounds demonstrated desirable multiple functions. The two most promising compounds 8a and 8b exhibited nanomolar IC 50 values on H 3 receptor antagonism, excellent metal ion chelating capability, more potent ABTS + scavenging activity than Trolox, efficient A β self-aggregation and Cu2+-induced aggregation inhibitory activities, as well as disaggregation activities against A β self/Cu2+-induced aggregation.
