4.2. Potential Drug Targets
It has been observed that there isn’t a prescribed regimen to follow
while treating COVID-19 as patients can exhibit a spectrum of clinical
symptoms. However, understanding the structure of the virus as well as
its mechanism of entry and infection of host cells has led to the
discovery of various drug targets that have been effective in the
treatment of disease. Essentially, the enzymes and proteins that are
crucial for viral replication and the control of the host cellular
functions can serve as potential drug targets . Thus, new drugs or
antagonists need to be developed that inhibit these enzymes, proteins,
and receptors which are solely required for the survival and
multiplication of viruses. Various drug targets that can be targeted for
therapy are discussed below.
