  Discovery of Imidazo[2,1-b]thiazole HCV NS4B Inhibitors Exhibiting Synergistic Effect with Other Direct-Acting Antiviral Agents

  摘要：

  The design, synthesis, and SAR studies of novel inhibitors of HCV NS4B based on the imidazo[2,1-b]thiazole scaffold were described. Optimization of potency with respect to genotype 1b resulted in the discovery of two potent leads 26f (EC50 = 16 nM) and 28g (EC50 = 31 nM). The resistance profile studies revealed that 26f and 28g targeted HCV NS4B, more precisely the second amphipathic alpha helix of NS4B (4BAH2). Cross-resistance between our 4BAH2 inhibitors and other direct-acting antiviral agents targeting NS3/4A, NS5A, and NS5B was not observed. For the first time, the synergism of a series of combinations based on 4BAH2 inhibitors was evaluated. The results demonstrated that our 4BAH2 inhibitor 26f was synergistic with NS3/4A inhibitor simeprevir, NS5A inhibitor daclatasvir, and NS5B inhibitor sofosbuvir, and it could also reduce the dose of these drugs at almost all effect levels. Our study suggested that favorable effects could be achieved by combining 4BAH2 inhibitors such as 26f with these approved drugs and that new all-oral antiviral combinations based on 4BAH2 inhibitors were worth developing to supplement or even replace current treatment regimens for curing HCV infection.

  This invention relates to certain tricyclic 6-alkylidene penems which act as a inhibitor of class-D enzymes. β-Lactamases hydrolyze β-lactam antibiotics, and as such serve as the primary cause of bacterial resistance. The compounds of the present invention when combined with β-lactam antibiotics will provide an effective treatment against life threatening bacterial infections. In accordance with the present invention there are provided compounds of formula I which are useful for treatment of bacterial infections having class-D enzymes associated therewith: wherein: One of A and B denotes hydrogen and the other an optionally substituted fused tricyclic heteroaryl group; and X is S or O.

  这项发明涉及某些三环6-烷基亚胺基青霉素，其作为类D酶的抑制剂。β-内酰胺酶水解β-内酰胺类抗生素，因此是细菌抗药性的主要原因。本发明的化合物与β-内酰胺类抗生素结合时，将提供一种有效治疗危及生命的细菌感染的方法。根据本发明，提供了以下公式I的化合物，其用于治疗与类D酶相关的细菌感染：其中：A和B中的一个表示氢，另一个表示可选择取代的融合三环杂芳基团；X为S或O。
