Synthesis and SAR of pyridothiazole substituted pyrimidine derived HCV replication inhibitors
摘要:
Introduction of a nitrogen atom into the benzene ring of a previously identified HCV replication (replicase) benzothiazole inhibitor 1, resulted in the discovery of the more potent pyridothiazole analogues 3. The potency and PK properties of the compounds were attenuated by the introductions of various functionalities at the R-1, R-2 or R-3 positions of the molecule (compound 3). Inhibitors 38 and 44 displayed excellent potency, selectivity (GAPDH/MTS CC50), PK parameters in all species studied, and cross genotype activity. (C) 2012 Elsevier Ltd. All rights reserved.
