Abstract
Till this date there is no vaccine or drug for coronavirus responsible
for COVID-19 which has created a major challenge to stop the spread of disease.
Repurposing of a drug could be a solution for this challenge, as many
previously available drugs hold great potential to act as a drug molecule. The
coronavirus mainly affects the host by binding to its specific receptor with
the help of its surface glycoprotein or spike glycoprotein. Thus, interfering
this interaction could be a potent mechanism to stop the viral infection and
propagation. In this paper, we have discussed about the surface glycoprotein
and how previously available drug could be repurposed to act as a potent
inhibitor. Homology modelling and docking studies has been mainly done to
identify the interaction and binding affinity of previous drugs and how they
could act as a potential solution to stop the overall spread of the disease in
case of pandemic like COVID-19 where unavailability of specific drug or vaccine
is responsible for taking to the lives of many.
