antiviraalide
Antiviraalide is an investigational antiviral compound that has appeared in early preclinical literature as a potential broad-spectrum agent against RNA viruses. It is described in some sources as a prodrug of a nucleoside analogue aimed at disrupting viral RNA synthesis by targeting the viral RNA-dependent RNA polymerase. In vitro studies have reported inhibition of replication for several RNA viruses, including coronaviruses, flaviviruses, and orthomyxoviruses, at concentrations with limited cytotoxicity in cultured cells. In animal models, antiviraalide administration has shown reduced viral loads in certain tissues and improved survival in some viral challenge experiments, though results remain preliminary and model-dependent.
Pharmacologically, antiviraalide is said to require intracellular phosphorylation to an active triphosphate form, where it competes
Development status remains experimental; no peer-reviewed phase I/II clinical trial data are publicly available, and antiviraalide
