Arguably, Alzheimer's disease (AD) is a multifactorial syndrome, rather than single disease, arising from a complex array of neurochemical factors. Numerous studies on the molecular pathogenesis of AD implicate a diversity of factors ranging from neurotoxic peptides (β‐amyloid) to inflammatory processes (interleukins), but all culminating in a common neuropathology. This diversity of molecular causation is an impediment to the design of effective therapies for AD. To address this design problem, we sought to identify a single, common motif (a “common receptor”) shared by multiple structurally and functionally diverse proteins implicated in AD. This search revealed the presence of a common BBXB peptide motif and upon refinement, an AXBBXB motif; these regions can be exploited for the design of a “promiscuous drug” that exploits a “one‐drug‐multiple‐receptors” therapeutic strategy for AD.
