Inosine monophosphate (IMP) dehydrogenase (IMPDH) is a significant enzyme in the purine nucleotide biosynthetic pathway. IMPDH is viewed as an important biological target in the quest for drugs in the antiviral therapeutic area. This review article is focused on the chemistry and biology of IMPDH inhibitors and the use of IMPDH inhibition data as a probe in antiviral drug discovery. Examples of...

July 2006 | Volume 3 | Issue 7 | e242 The Need for New Antiviral Therapies Viruses are formidable targets for drug development. As obligate intracellular parasites that take over the host cellular machinery to further their own agenda, they seem to understand the intimate workings of cellular pathways better than those seeking to develop treatments against them. It is diffi cult to inactivate a...

The antiviral QSAR models have an important limitation today. They predict the biological activity of drugs against only one viral species. This is determined by the fact that most of the current reported molecular descriptors encode only information about the molecular structure. As a result, predicting the probability with which a drug is active against different viral species with a single u...

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a highly transmissible and pathogenic coronavirus that emerged in late 2019 and has caused a pandemic of acute respiratory disease, named ‘coronavirus disease 2019’ (COVID-19), which threatens human health and public safety.Hydroxychloroquine (HCQ) is an anti-malaria drug; its antiviral properties are controversial,and some in vitr...
