Novel Drug Development for Treatment of COVID-19 by In Silico Analysis: Identification of SARS-Cov-2 Inhibiting Streptomyces Compounds
In accordance with the present epidemiological paradigm, viral mutations of the virus are on the rise, and their natural effects are being selected for at a higher rate than normal. According to the World Health Organization (WHO), the global COVID-19 pandemic induced by the Delta and Omicron strain of the SARS-CoV-2 virus could propagate and disseminate more rapidly than other viruses thanks to its many mutations, and these also caused some very significant health problems.

According to Sahu et al., COVID-19 epidemic is the third most common coronavirus in the 21st century, resulting in numerous deaths all over the world. It has caused severe psychological stress and increased hospital visits along with increased tiredness and burnout of medical staff. The disease has also raised many problems for the management of hospitals and diagnostic-treatment centers, so that many of them have no capacity to receive patients.
What Do You Know So Far about the D-dimer Levels in COVID-19?
The Severe Acute Respiratory Syndrome, Coronavirus 2 (SARS-Cov-2), was first linked to cases of pneumonia of unknown cause in which they began to be reported in Wuhan, China. This represents a major threat to global health, and by the end of June, about 503 thousand deaths worldwide were found due to this disease. Coronaviruses are known for their great potential to cause systemic diseases, including changes in coagulation.
