Cover Story: The SARS-CoV-2 is a high-risk virus involved in the coronavirus pandemic. The most common symptoms are fever, dyspnea, asthenia, cough, anosmia, headache, dysgeusia, and interstitial acute pneumonia in severe cases. The spike protein S, is able to bind the host cell angiotensin-converting enzyme 2 receptor (ACE-2) involved in the invasion of the virus in the lungs and intestine. The SARS-CoV-2 protein S, is 76.5% similar to the SARS-CoVs and MERS-CoV S protein. Different substances are able to block the ACE-2 receptor and, hence, could potentially represent promising therapies against SARS-CoV-2. View this paper
