Novel TACE inhibitors in drug discovery: a review of patented compounds.

TNF-alpha converting enzyme (TACE), a pro-inflammatory cytokine, catalyzes the formation of TNF-alpha from membrane bound TNF-alpha precursor protein. TNF-alpha is believed to play pathophysiological roles in inflammation, anorexia, cachexia, septic shock, viral replication and so on. TNF-alpha is a key player in inflammation and joint damage in rheumatoid arthritis.

Studies on novel 2-imidazolidinones and tetrahydropyrimidin-2(1H)-ones as potential TACE inhibitors: design, synthesis, molecular modeling, and preliminary biological evaluation.

Compounds belonging to the class of 2-imidazolidinones and tetrahydropyrimidin-2(1H)-ones were synthesized and evaluated for their TACE inhibitory activity. Most of the compounds showed very good TACE inhibitory activity. Docking study clearly indicates importance of the P1' group of the inhibitor for the TACE inhibitory activity.

Current perspective of TACE inhibitors: a review.

Rheumatoid Arthritis (RA) is one of the most common autoimmune inflammatory conditions, affecting approximately 1% of the adult population worldwide. TNF-alpha is a pleitropic, pro-inflammatory cytokine which plays a pivotal role in the origin and progression of RA and other immune mediated disorders. The success of anti-TNF-alpha biological agents proved that inhibition of TNF-alpha could result in effective control of RA.
