Compounds of Formula (I) and methods of inhibiting the replication of viruses in a biological sample or patient, of reducing the amount of viruses in a biological sample or patient, and of treating a virus infection in a patient, comprising administering to said biological sample or patient an effective amount of a compound represented by Formula (I), a compound of Table A or B or a pharmaceutically acceptable salt thereof.
The present invention is directed to compounds that are antiviral agents. Specifically, the compounds of the present invention inhibit replication of HCV and are therefore useful in treating hepatitis C infections. The present invention is also directed to pharmaceutical compositions comprising these compounds and processes for preparing them.

The present invention discloses novel compounds which have HCV protease inhibitory activity as well as methods for preparing such compounds. In another embodiment, the invention discloses pharmaceutical compositions comprising such compounds as well as methods of using them to treat disorders associated with the HCV protease.
α-Keto amide derivatives as enterovirus 71 (EV71) 3C protease (3Cpro) inhibitors have been synthesized and assayed for their biochemical and antiviral activities. structure–activity relationship (SAR) study indicated that small moieties were primarily tolerated at P1′ and the introduction of para-fluoro benzyl at P2 notably improved the potency of inhibitor. Inhibitors 8v, 8w and 8x exhibited satisfactory

Malaria control programs continue to be threatened by drug resistance. To identify newantimalarials, we conducted a phenotypic screen and identified a novel tetrazole-based series that shows fast-kill kinetics and a relatively low propensity to develop high-level resistance. Preliminary structure–activity relationships were established including identification of a subseries of related amides with
