  Anticonvulsant activity of 2,4(1H)-diarylimidazoles in mice and rats acute seizure models

  摘要：

  2,4(1H)-Diarylimidazoles have been previously shown to inhibit hNaV1.2 sodium (Na) channel currents. Since many of the clinically used anticonvulsants are known to inhibit Na channels as an important mechanism of their action, these compounds were tested in two acute rodent seizure models for anticonvulsant activity (MES and scMet) and for sedative and ataxic side effects. Compounds exhibiting antiepileptic activity were further tested to establish a dose response curve (ED(50)). The experimental data identified four compounds with anticonvulsant activity in the MES acute seizure rodent model (compound 10, ED(50) = 61.7 mg/kg; compound 13, ED(50) = 46.8 mg/kg, compound 17, ED(50) = 129.5 mg/kg and compound 20, ED(50) = 136.7 mg/kg). Protective indexes (PI = TD(50)/ED(50)) ranged from 2.1 (compound 10) to greater than 3.6 (compounds 13, 17 and 20). All four compounds were shown to inhibit hNaV1.2 in a dose dependant manner. Even if a correlation between sodium channel inhibition and anticonvulsant activity was unclear, these studies identify four Na channel antagonists with anticonvulsant activity, providing evidence that these derivatives could be potential drug candidates for development as safe, new and effective antiepileptic drugs (AEDs).

  从酮和醛模块合成二取代和三取代的咪唑：激酶抑制剂的途径。

  摘要：

  基于酮氧化，采用催化HBr和DMSO，然后通过咪唑与醛的缩合反应，开发了一种单罐模块化方法，用于合成2,4（5）-二取代的咪唑。该方法提供了二十九个二取代的NH-咪唑（23％-85％的产率）。通过采用这种氧化-缩合方案，然后在咪唑环中进行溴化和Suzuki偶联，得到三取代的NH-咪唑（23％-69％，三步法），实现了三步合成20种激酶抑制剂的过程。该方法还用于合成已知抑制剂GSK3037619A。

  A simple and efficient approach to selectively obtain 2,4(5)-diarylimidazoles suppressing formation of 2-aroyl-4(5)-arylimidazoles is described. The yield of each of the two products strongly depends on the reaction conditions employed. This reaction provides a simple method to prepare small libraries of biologically active compounds by parallel synthesis.

  日期：2018.12.7

  ZnCl2-catalyzed [3 + 2] cycloaddition reaction of benzimidates and 2H-azirines has been developed. This convenient method allowed the efficient construction of a series of multisubstituted imidazoles in moderate to good yields under mild reaction conditions. This transformation exhibits good reactivity and high functional group tolerance.
