The 2019 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a newly emerging respiratory illness. The epidemic started in December 2019 in Wuhan, China, and has rapidly spread throughout China and the world and is now a global pandemic. SARS-CoV-2 can be efficiently transmitted among humans and has shown a high degree of morbidity and mortality [1,2]. As of April 20, 2020, the worldwide number of infected individuals was 2,544,792, with as many as 175,694 deaths [3]. There are currently no approved vaccines available for the prevention of SARS-CoV-2 infection and only just recently, remdesivir has received “emergency use authorization” for treatment of COVID-19 in the United States; therefore, there is an urgent demand for potential chemotherapeutic agents to treat this disease.
