  Structure−Activity Relationships for 1-Phenylbenzimidazoles as Selective ATP Site Inhibitors of the Platelet-Derived Growth Factor Receptor

  摘要：

  1-Phenylbenzimidazoles are shown to be a new class of ATP-site inhibitors of the platelet-derived growth factor receptor (PDGFR). Structure-activity relationships (SARs) are narrow, with closely related heterocycles being inactive. A systematic study of substituted 1-phenyl-benzimidazoles showed clear SARs. Substituents at the 4'- and 3'-positions of the phenyl ring are tolerated but do not significantly improve activity, while substituents at the 2'-position abolish it. Substituents in the 2-, 4-, and 7-positions of the benzimidazole ring (with the exception of 4-OH) also abolish activity. Most substituents at the 5- and B-positions maintain or increase activity, with the 5-OH, 5-OMe, 5-COMe, and 5-CO2Me analogues being >10-fold more potent than the parent 1-phenylbenzimidazole. The 5-OMe analogue was both the most potent inhibitor, and showed the highest selectivity (50-fold) between PDGFR and FGFR isolated enzymes, and also a moderately effective inhibitor (IC50 = 1.9 mu M) of PDGF-stimulated PDGFR autophosphorylation in rat aorta smooth muscle cells.

  It was determined that diaryliodonium(III) triflates bearing a trimethoxybenzene (TMP) auxiliary are more reactive than the reported selective aryl-transfer iodonium salts in the N-arylation of benzimidazoles and other types of azole compounds under catalytic conditions. The TMP-iodonium(III) salts can thus effectively facilitate the reaction at 50 °C or below, producing the corresponding N-arylated

  已确定在催化条件下，在苯并咪唑和其他类型的唑化合物的N-芳基化反应中，带有三甲氧基苯（TMP）助剂的二芳基碘鎓（III）三氟甲磺酸盐比报道的选择性芳基转移碘鎓盐更具反应性。因此，TMP-碘鎓（III）盐可以有效地促进在50℃或更低的温度下反应，产生相应的N-芳基化的联芳基，而不会形成TMP-衍生的偶联副产物。在温和的条件下使用该TMP试剂可防止潜在的辅助基团参与偶联反应的问题，这是在使用需要升高温度的碘鎓（III）盐时观察到的。
