  Synthesis and antiviral activity of novel HCV NS3 protease inhibitors with P4 capping groups

  摘要：

  We have synthesized and evaluated a series of novel HCV NS3 protease inhibitors with various P4 capping groups, which include urea, carbamate, methoxy-carboxamide, cyclic carbamate and amide, pyruvic amide, oxamate, oxalamide and cyanoguanidine. Most of these compounds are remarkably potent, exhibiting single-digit to sub-nanomolar activity in the enzyme assay and cell-based replicon assay. Selected compounds were also evaluated in the protease-inhibitor-resistant mutant transient replicon assay, and they were found to show quite different potency profiles against a panel of HCV protease-inhibitor-resistant mutants.

  In its many embodiments, the present invention provides certain iminothiadiazine dioxide compounds, including compounds Formula (I): and include stereoisomers thereof, and pharmaceutically acceptable salts of said compounds stereoisomers, wherein each of R 1 , R 2 , R 3 , R 4 , R 5 , R 9 , ring A, ring B, m, n, p, -L 1 -, -L 2 -, and -L 3 - is selected independently and as defined herein. The novel iminothiadiazine dioxide compounds of the invention have surprisingly been found to exhibit properties which are expected to render them advantageous as BACE inhibitors and/or for the treatment and prevention of various pathologies related to β-amyloid (“Aβ”) production. Pharmaceutical compositions comprising one or more such compounds (alone and in combination with one or more other active agents), and methods for their preparation and use in treating pathologies associated with amyloid beta (Aβ) protein, including Alzheimer's disease, are also disclosed.
