The chaperone protein HSPA5/Dna K is conserved throughout evolution from higher eukaryotes down to prokaryotes. The celecoxib derivative OSU-03012 (also called AR-12) interacts with Viagra or Cialis in eukaryotic cells to rapidly reduce HSPA5 levels as well as blunt the functions of many other chaperone proteins. Because multiple chaperones are modulated in eukaryotes, the expression of cell surface virus receptors is reduced and because HSPA5 in blocked viruses cannot efficiently replicate. Because DnaK levels are reduced in prokaryotes by OSU-03012, the levels of DnaK chaperone proteins such as Rec A decline, which is associated with bacterial cell death and a resensitization of so-called drug-resistant superbugs to standard of care antibiotics. In Alzheimer's disease, HSPA5 has been shown to play a supportive role for the progression of tau phosphorylation and neurodegeneration. Thus, in eukaryotes, HSPA5 represents a target for anticancer, antiviral, and anti-Alzheimer's therapeutics and in prokaryotes, DnaK and bacterial phosphodiesterases represent novel antibiotic targets that should be exploited in the future by pharmaceutical companies.
