  • PubMed Abstract: 

    Adenoviral infections are associated with a wide range of acute diseases, among which ocular viral conjunctivitis (EKC) and disseminated disease in immunocompromised patients. To date, no approved specific anti-adenoviral drug is available, but there is a growing need for an effective treatment of such infections. The adenoviral protease, adenain, plays a crucial role for the viral lifecycle and thus represents an attractive therapeutic target. Structure-guided design with the objective to depeptidize tetrapeptide nitrile 1 led to the novel chemotype 2. Optimization of scaffold 2 resulted in picomolar adenain inhibitors 3a and 3b. In addition, a complementary series of irreversible vinyl sulfone containing inhibitors were rationally designed, prepared and evaluated against adenoviral protease. High resolution X-ray co-crystal structures of representatives of each series proves the successful design of these inhibitors and provides an excellent basis for future medicinal chemistry optimization of these compounds.
