Background: COVID-19 has been declared as a pandemic recently and has caused many deaths worldwide. Till date, no effective drug or vaccine is available against SARS-CoV-2. There is an urgent need to find effective alternative preventive and treatment strategies to deal with the SARS-CoV- 2 outbreak.
Objective: This communication proposes a new potential drug combination (repurposed) for prophylaxis and treatment of SARS-CoV-2.
Methods and Materials: We performed a brief review of literature on a combination of Hydroxychloroquine, Melatonin and Mercaptopurine for prophylaxis and treatment of Novel COVID-19 infection and also assessed their possible mechanism of action against SARS-CoV-2.
Observation: Proposed combination seems to be safe, and the target is unlikely to develop resistance to this combination.
Conclusion: This scientific review proposes potential candidate repurposed drugs and potential drug combinations targeting 2019-nCoV/SARS-CoV-2.
Keywords: Novel COVID-19, Hydroxychloroquine, Melatonin, Mercaptopurine, coronavirus, Prophylaxis.
