Covid-19: Pathophysiology; Mechanism of Transmission and Possible Molecular Drug Target for Management.

Coronavirus disease 2019 (COVID-19) is caused by Severe Acute Respiratory Syndrome Coronaviruses 2 (SARS-CoV-2). At present, it is a potentially fatal disease and is of great global public health concern. The pathophysiological understanding of the mode of transmission of COVID-9 and the possible molecular targets are exploring successively to fight against this contagious disease.

A review on possible modes of action of chloroquine/hydroxychloroquine: repurposing against SAR-CoV-2 (COVID-19) pandemic.

Chloroquine (CQ) and its analogue hydroxychloroquine (HCQ) have long been used worldwide as frontline drugs for the treatment and prophylaxis of human malaria. Since the first reported cases in Wuhan, China, in late December 2019, humans have been under threat from coronavirus disease 2019 (COVID-19) caused by the novel coronavirus SARS-CoV-2 (previously known as 2019-nCoV), subsequently declared a pandemic. While the world is searching for expedited approval for a vaccine, which may be only preventative and not a cure, physicians and country leaders are considering several concerted clinical trials suggesting that the age-old antimalarial drugs CQ/HCQ could be a potent therapeutic against COVID-19.
