Synthesis And Evaluation Of Novel Nucleotide Prodrugs Against Sars-Cov-2, Mohammed Attaelmanan

Electronic Thesis and Dissertation Repository

Positive sense RNA (ribonucleic acid) viruses (+ssRNA) are the known causative agents of diseases throughout history. These includes Hepatitis C Virus (HCV), SARS-CoV, and recently SARS-CoV-2. RNA dependent RNA polymerase (RdRp), a critical enzyme in the life cycle of the virus, can be targeted by using nucleotide antivirals thus causing inhibition. Novel ribonucleotides antiviral agents that possess nucleobase modifications and a 5′-phosphoramidate prodrug moiety, referred to as a ProTide, have been synthesized. The ribonucleoside analogues were constructed by CuI catalyzed azide-alkyne cycloaddition chemistry (CuAAC), also referred to as ‘click’ chemistry. The synthetic route utilized 5-ethynylpyrimidines and azidoribofuranoses as CuI ‘click’ …
