  Optimization of Small-Molecule Inhibitors of Influenza Virus Polymerase: From Thiophene-3-Carboxamide to Polyamido Scaffolds

  摘要：

  Influenza virus infections represent a serious concern to public health, being characterized by high morbidity and significant mortality. To date, compounds targeting the viral ion-channel M2 or the viral neuraminidase are the drugs available for treatment of influenza, but the emergence of drug-resistant viral mutants renders the search for novel targets and their possible inhibitors a major priority. Recently, we I I demonstrated that the viral RNA-dependent RNA polymerase (RdRP) complex can be an optimal target of protein protein disruption by small molecules, with thiophene-3-carboxamide derivatives emerging as promising candidates for the development of new anti-influenza drugs with broad-spectrum activity. Here, we report a further dissection of the thiophene-3-carboxamide structure. By using a GRID molecular interaction field (MIF)-based scaffold-hopping approach, more potent and nontoxic polyamido derivatives were identified, highlighting a new space in the chemical variability of RdRP inhibitors. Finally, a possible pharmacophoric model highlighting the key features required for RdRP inhibition is proposed.

  Methods for treating an individual having cancer are provided. The method may include administering a cell migration inhibitor and a chemotherapeutic agent to the individual to inhibit migration of cancer cell. Inhibiting cell migration may increase cell division. In this manner, the cell migration inhibitor and the chemotherapeutic agent in combination may have increased efficacy compared to the chemotherapeutic agent alone due to the increased cell division. The cell migration inhibitor may include any of the inhibitors described herein. For example, the cell migration inhibitor may be an organic molecule having a molecular weight of less than about 700, a monoclonal antibody, or a natural product.

  本文提供了治疗癌症患者的方法。该方法可包括向患者施用细胞迁移抑制剂和化疗药物，以抑制癌细胞的迁移。抑制细胞迁移可增加细胞分裂。这样，由于细胞分裂增加，细胞迁移抑制剂和化疗剂联合使用的疗效可能比单独使用化疗剂的疗效更好。细胞迁移抑制剂可包括本文所述的任何抑制剂。例如，细胞迁移抑制剂可以是分子量小于约 700 的有机分子、单克隆抗体或天然产物。
