The present patent application is directed to bicyclic compounds of formula (I) or pharmaceutically acceptable salt thereof as mPGES-1 inhibitors. These compounds are inhibitors of the microsomal prostaglandin E synthase-1 (m PGES-1) enzyme and are therefore useful in the treatment of pain and/or inflammation from a variety of diseases or conditions, such as asthma, osteoarthritis, rheumatoid arthritis, acute or chronic pain and neurodegenerative diseases.

We describe here the design, Synthesis, molecular modeling. and biological evaluation of a series of small molecule, nonpeptide inhibitors of SARS-CoV PLpro. Our initial lead compound was identified via high-throughput screening of a diverse chemical library. We subsequently carried out structure-activity relationship studies and optimized the lead structure to potent inhibitors that have shown antiviral activity against SARS-CoV infected Vero E6 cells, Upon the basis of the X-ray crystal structure of inhibitor 24-bound to SARS-CoV PLpro, a drug design template was created. Our structure-based modification led to the design of a more potent inhibitor, 2 (enzyme IC50 = 0.46 mu M; antiviral EC50 = 6 mu M). Interestingly. its methylamine derivative, 49, displayed good enzyme inhibitory potency (IC50 = 1.3 mu M) and the most potent SARS antiviral activity (EC50 = 5.2 mu M) in the series, We have carried our computational docking studies and generated a predictive 3D-QSAR model for SARS-CoV PLpro inhibitors.
The present invention discloses compounds of Formula (I), and pharmaceutically acceptable salts, thereof which inhibit coronavirus replication activity. The invention further relates to pharmaceutical compositions comprising a compound of Formula (I) or a pharmaceutically acceptable salt thereof, and methods of treating or preventing a coronavirus infection in a subject in need thereof, comprising administering to the subject a therapeutically effective amount of a compound of Formula (I) or a pharmaceutically acceptable salt thereof.
