We found that curcumin and few of its derivatives showed promising results to be potential spike protein inhibitors. One of the derivatives, bis-demethoxycurcumin, showed the best binding affinity to the spike protein of both the SARS-CoV and the novel corona virus, SARS-CoV-2. The possibility for few of the curcumin derivatives, that showed good binding affinity, could be tested for further therapeutic use against COVID-19.
