  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.

• Cascade Palladium Catalysis: A Predictable and Selectable Regiocontrolled Synthesis of<i>N</i>-Arylbenzimidazoles

  choice: The palladium‐catalyzed cascade reaction of 2‐chloroaryl sulfonates with arylamine and amide nucleophiles provides direct access to N‐arylbenzimidazoles. This strategy selectively produces the heterocycles based on chemoselective oxidative addition. 2‐Chloroaryl triflates (Tf) produce one regioisomer and the corresponding 2‐chloroaryl mesylates (Ms) deliver the other in a selectable manner.

  cost-effective aryl source has been efficiently effected via Cu(OAc)2-catalyzed Chan-Lam coupling in assistance of tetramethylethylenediamine (TMEDA) in methanol and pyridine (Py) in dichloromethane, respectively, in air at room temperature. The diarylborinic acids could be well accommodated by the Chan-Lam coupling oxidative conditions containing a proper combination of bases and solvents. The steric

  借助Cu（OAc）2催化的Chan-Lam偶联，借助四甲基乙二胺（TMEDA）在甲醇和吡啶（Py）中的催化作用，已有效地实现了（苯）咪唑和胺与二芳基硼酸作为具有成本效益的芳基源的N-芳基化作用。室温下分别置于二氯甲烷中。包含适当的碱和溶剂组合的Chan-Lam偶联氧化条件可以很好地容纳二芳基硼酸。与电子因素相比，使用高阶芳基硼试剂时，空间位阻似乎对铜催化的N-芳基化的影响更大，尤其是对于低反应性苯胺和脂肪族胺而言。

  several pinacol or neopentylglycol boronates indicated further potential of the catalyst. The reaction conditions tolerate the hydroxyl and bromo functional groups. The catalytic system also enables to synthesize the mono-N-substituted anilines from primary aliphatic amines.
