The present invention provides a group of novel compounds that inhibit the proteolytic activity of 3C proteases which are found in picornaviruses particularly, rhinoviruses. In picornaviruses the RNA genome is translated into a single large viral polyprotein precursor. The precursor demonstrates auto-proteolytic activity cleaving itself into mature viral gene products. Therefore compounds of the current invention are particularly useful in treating picornaviral infections by interrupting the processing of the viral gene products into mature and infectious viral particles.

Why it's free to use
- Filed June 30, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 30, 2014.
