2-Anilino-4-aryl-1,3-thiazole inhibitors of valosin-containing protein (VCP or p97)
摘要:
Valosin-containing protein (VCP; also known as p97) is a member of the AAA ATPase family with a central role in the ubiquitin-degradation of misfolded proteins. VCP also exhibits antiapoptotic function and metastasis via activation of nuclear factor kappa-B signaling pathway. We have discovered that 2-anilino-4-aryl-1,3-thiazoles are potent drug-like inhibitors of this enzyme. The identified compounds show low nanomolar VCP potency, demonstrate SAR trends, and show activity in a mechanism based cellular assay. This series of compounds represents the first steps towards a novel, small molecule VCP inhibitor as a cancer therapeutic. (C) 2010 Elsevier Ltd. All rights reserved.

Biological evaluation of N‐aryl‐4‐aryl‐1,3‐thiazole‐2‐amine derivatives was examined for anti‐inflammatory activity in in vitro and in vivo assays. The thiazole compounds showed direct inhibition of 5‐lipoxygenase (LOX) that is a key enzyme of leukotrienes synthesis and involved in the inflammation‐related diseases, including asthma and rheumatoid arthritis. To optimize biological activity, we synthesized 1

The invention also provides compounds of Formula I that are potent and/or selective inhibitors of Hepatitis C virus replication. Certain compounds described herein inhibit assembly of the HCV replication complex. The invention also provides pharmaceutical compositions containing one or more compounds of Formula I, or a salt, solvate, or acylated prodrug of such compounds, and one or more pharmaceutically acceptable carriers, excipients, or diluents. The invention further comprises methods of treating patients suffering from certain infectious diseases by administering to such patients an amount of a compound of Formula I effective to reduce signs or symptoms of the disease. These infectious diseases include viral infections, particularly HCV infections. The invention is particularly includes methods of treating human patients suffering from an infectious disease, but also encompasses methods of treating other animals, including livestock and domesticated companion animals, suffering from an infectious disease. Methods of treatment include administering a compound of Formula I as a single active agent or administering a compound of Formula I in combination with on or more other therapeutic agent.
