  Imidazole-based pinanamine derivatives: Discovery of dual inhibitors of the wild-type and drug-resistant mutant of the influenza A virus

  摘要：

  We previously reported potent hit compound 4 inhibiting the wild-type influenza A virus A/HK/68 (H3N2) and A/M2-S31N mutant viruses A/WS/33 (H1N1), with its latter activity quite weak. To further increase its potency, a structure-activity relationship study of a series of imidazole-linked pinanamine derivatives was conducted by modifying the imidazole ring of this compound. Several compounds of this series inhibited the amantadine-sensitive virus at low micromolar concentrations. Among them, 33 was the most potent compound, which was identified as being active on an amantadine-sensitive virus through blocking of the viral M2 ion channel. Furthermore, 33 markedly inhibited the amantadine-resistant virus (IC50 = 3.4 mu M) and its activity increased by almost 24-fold compared to initial compound, with its action mechanism being not M2 channel mediated.

  The pseudotetrapeptide FR-139317 is a potent and highly selective antagonist of the endothelin-A (ET(A)) receptor; however, its peptidic nature leads to poor oral absorption characteristics which make it an unlikely drug candidate. In an attempt to improve these properties, we have replaced a portion of the amide bond framework of FR-139317 with a heterocyclic surrogate. The resultant analogs are also ET(A)-selective antagonists, but show a structure-activity profile substantially different from that of the peptidic series, particularly with regard to the requirements for the side chain group that has been incorporated into the heterocycle. The nature of the heterocycle itself also has profound effects on the activity of the compounds. Both of these surprising results can be rationalized through examination of a 3D model of ET ligand-receptor binding that has previously been developed in our laboratories.
