Many promising kinase inhibitors may be beneficial in treating COVID-19’s severe and occasionally deadly symptoms. Infection can be prevented by directly targeting the virus and reducing clinical signs using kinase inhibitors. Kinases can also be utilized to boost the efficacy of other antiviral medicines or tailored treatments for SARS-CoV-2. Many kinase inhibitors are now being tested in clinical studies to see if they work as a viable cure.
In addition
It should be emphasized that tyrosine kinase inhibitors (TKI) are critical in the prevention of SARS-CoV-2 infection in patients with Ph + ALL and CML (Galimberti et al., 2020). Galimberti et al. (2020) stated that in an Italian cohort analysis of Ph + ALL and CML patients, they discovered that just a few individuals have COVID-19. They concluded that the usage of TKIs may have contributed to the reduced rate of infection. It is fascinating that patients treated with TKIs such as imatinib or nilotinib exhibited increased expression of various pro-immune genes such as CD28 and IFN, but decreased expression of anti-immune genes such as ARG-1, CEACAMI, and FUT4. As discussed previously, SARS-CoV infection occurs through a series of steps: receptor engagement, conformational modification of S-glycoprotein, and cathepsin-L-induced proteolysis within endosomes (Simmons et al., 2005). It has been shown that the infection of SARS-CoV can be inhibited by targeting the inhibitors of cathepsin L (Simmons et al., 2005). In keeping with the preceding point, it should be noted that cells can be treated with cathepsin inhibitors as well as serine protease inhibitors to induce complete viral entry and replication. Camostat is a protease inhibitor that blocks the activity of type II trans-membrane serine protease (TTSP). Shirato et al. (2013) describe how TMPRSS2 cleaves the S glycoprotein of CoV and helps in the entry of the virus into the host cell.
