  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).

  Novel Oxidative α-Tosyloxylation of Alcohols with Iodosylbenzene and p-Toluenesulfonic Acid and Its Synthetic Use for Direct Preparation of Heteroaromatics

  摘要：

  alpha-Tosyloxyketones and alpha-tosyloxyaldehydes were directly prepared from alcohols by treatment with iodosylbenzene and p-toluenesulfonic acid monohydrate in good yields. This method can be used for the direct preparation of thiazoles, imidazoles, and imidazo[1,2-alpha]pyridines from alcohols in good to moderate yields by the successive treatment with iodosylbenzene and p-toluenesulfonic acid monohydrate, followed by thioamides, benzamidine, and 2-aminopyridine, respectively.

• Base-Mediated Syntheses of Di- and Trisubstituted Imidazoles from Amidine Hydrochlorides and Bromoacetylenes
  作者：Xiao Yun Chen、Ulli Englert、Carsten Bolm

  日期：2015.9.14

  A new transition metal‐free method for the preparation of substituted imidazoles from easy‐to‐handle amidine hydrochlorides and bromoacetylenes has been developed. The reactions proceed in air and use inexpensive K2CO3 as base. Additions of 2,2′‐bipyridine and water have beneficial effects on the product yields. Various di‐ and trisubstituted imidazoles have been prepared in good yields (up to 88 %)

  of imidazole ring by a Cs2CO3-promoted annulation of amidoximes with terminal alkynes in DMSO has been developed. This protocol provides a simple synthetic route with high atom-utilization for the synthesis of 2,4-disubstituted imidazoles in good yields under transition-metal-free and ligand-free conditions. Internal alkynes can also undergo the annulation to give 2,4,5-trisubstituted imidazoles.
