  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.

  Described herein are silicon based conjugates capable of delivering one or more payload moieties to a target cell or tissue. Contemplated conjugates may include a silicon-heteroatom core, one or more optional catalytic moieties, a targeting moiety that permits accumulation of the conjugate within a target cell or tissue, one or more payload moieties (e.g., a therapeutic agent or imaging agent), and two or more non-interfering moieties covalently bound to the silicon-heteroatom core.

  本文描述了基于硅的共轭物，能够将一个或多个有效载荷基团传递到靶细胞或组织。考虑到的共轭物可能包括一个硅-杂原子核心，一个或多个可选的催化基团，一个定位基团，允许共轭物在靶细胞或组织内积累，一个或多个有效载荷基团（例如，治疗剂或成像剂），以及与硅-杂原子核心共价结合的两个或更多个不干扰基团。
