Drug repositioning identifies new indications for known drugs. Here we report
repositioning of the malaria drug amodiaquine as a potential anti-cancer agent.
While most repositioning efforts emerge through serendipity, we have devised a
computational approach, which exploits interaction patterns shared between
compounds. As a test case, we took the anti-viral drug brivudine (BVDU), which
also has anti-cancer activity, and defined ten interaction patterns using our
tool PLIP. These patterns characterise BVDU's interaction with its target s.
Using PLIP we performed an in silico screen of all structural data currently
available and identified the FDA approved malaria drug amodiaquine as a promising
repositioning candidate. We validated our prediction by showing that amodiaquine
suppresses chemoresistance in a multiple myeloma cancer cell line by inhibiting
the chaperone function of the cancer target Hsp27. This work proves that PLIP
interaction patterns are viable tools for computational repositioning and can
provide search query information from a given drug and its target to identify
structurally unrelated candidates, including drugs approved by the FDA, with a
known safety and pharmacology profile. This approach has the potential to reduce
costs and risks in drug development by predicting novel indications for known
drugs and drug candidates.
