Recent Advances in N-Heterocycles for COVID-19 Treatment - A Mini Review

Severe emergencies occurred across the globe, beginning with the outbreak of SARSCoV in 2002, followed by MERS-CoV in 2012. In December 2019, an acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was identified in Wuhan, China as the agent responsible for the recent COVID-19 pandemic outbreak. The virus rapidly spread throughout the world due to its high transmissibility, leading to enormous health problems and complexities. The COVID-19 pandemic has affected public health, the weak persons were severely affected by this virus. To stop the disease from spreading further, effective remedies are the need of the hour. Although SARS-CoV-2 vaccination campaigns are being carried out all over the globe, several new SARS-CoV-2 variants have emerged, and each has caused a wave of infections, highlighting an urgent need for therapeutics targeting SARS-CoV-2. Heterocyclic compounds have been explored extensively for a very long time for their biological activities, namely, anti-inflammatory, antimalarial, antitubercular, anticancer, antiviral, antimicrobial, antidiabetic, and many more bio-activities. Through this review, the author has tried to report the heterocyclic compounds synthesized all over the world over the last 2 years to fight against the SARS CoV-2 coronaviruses. The heterocyclic motifs mentioned in the review can serve as important resources for the development of COVID-19 treatment methods.
