  Anticonvulsant Activity and Interactions with Neuronal Voltage-Dependent Sodium Channel of Analogues of Ameltolide

  摘要：

  Fifteen compounds related to ameltolide (LY 201116) were studied for (i) anticonvulsant potential in the maximal electroshock-induced seizures (MES) and the subcutaneous pentylenetetrazol (sc Ptz) tests in mice and rats and (ii) interactions with neuronal voltage-dependent sodium channels. Compounds were chosen ranging in anticonvulsant activity in mice from very active to inactive. The active compounds were defined as those protecting 50% of the animals at doses between 10 and 50 mu mol/kg and inactive compounds as those protecting 50% of the animals at doses greater than 1 mmol/kg. The series studied included three N-(2,6-dimethylphenyl)benzamides (compounds 1, 2 (ameltolide), and 3), three N-(2,2,6,6-tetramethyl)piperidinyl-4-benzamides (compounds 4, 5, 6), one phenylthiourea (compound 7), five N-(2,6-dimethylphenyl)phthalimides (compounds 8, 9, 10, 13, and 14), two N-phenylphthalimide derivatives (compounds 11 and 12), and one N-(2,2,6,6-tetramethyl)piperidinyl-4-phtalimide (compound 15). Phenytoin (PHT) was employed as the reference prototype antiepileptic drug. After inital screening in mice, compounds 1, 2, 3, 5, 8, 9, 10, 13, and 14 were selected for further testing in rats. Anticonvulsant ED(50)s (effective doses in at least 50% of animals tested) of compounds in the MES test were determined in rats dosed orally and amounted to 52 (1), 135 (2), 284 (3), 31 (8), 131 (9), 25 (10), 369 (13), 354 (14), and 121 (PHT) mu mol/kg, compound 5 presenting with an ED50 value higher than 650 mu mol/kg. In our hands, the apparent IC(50)s (inhibitory concentrations 50) of compounds toward binding to rat brain synaptosomes of [H-3]batrachotoxinin-A-20 alpha-benzoate were 0.25 (1), 0.97 (2), 0.35 (3), 25.8 (5), 161.3 (8), 183.5 (9), 0.11 (10), 1.86 (13), 47.8 (14), and 0.86 (PHT) mu M. The relationship between the activity in the MES test and the capacity to interact in vitro with neuronal voltage-dependent sodium channels and the fact that the IC50 values obtained in the in vitro test are close to the brain concentrations at which anticonvulsant activities are reported to occur for ameltolide strongly suggest that the anticonvulsant properties of most compounds tested could be a direct result of their interaction with the neuronal voltage-dependent sodium channel.

  boronates, optimization of novel covalent-reversibly binding warheads remains largely unattended. We previously reported α-ketoamides to be a promising reversible lead motif, yet the cytotoxic activity required further optimization. This work focuses on the lead optimization of phenoxy-substituted α-ketoamides combining the structure-activity relationships from the primed and the non-primed site of the

  A variety of nitroindoles have been prepared from imidate, amidine, and sec-anilide derivatives of 2-alkyl-3- or 5-nitroanilines by a base-induced cyclization promoted by dialkyl oxalates. It is shown that essentially the same procedure also can be used to synthesize the corresponding nitroindole-3-glyoxylates in one simple operation. The synthetic potential is discussed and a mechanism is proposed

  An efficient oxidative NHC-catalyzed one-step transformation of (S)- or (R)-8-oxocitronellal to nepetalactone (NL) in enantio- and diastereomerically pure form has been developed. Several new and "easy to make" N-Mes- or N-Dipp-substituted 1,2,4-triazolium salts carrying nitroaromatic groups on N1 were synthesized and evaluated as precatalysts in combination with base and stoichiometric organic oxidant
