烯胺酮衍生物作为治疗癫痫的潜在抗惊厥剂已被广泛研究。我们的研究小组致力于评估通过 sp2 杂化连接体连接到取代芳环的环状烯胺酮的抗惊厥活性。我们在此报告我们的先导优化工作以及随后从氟化中间体合成目标氟化N-苯甲酰胺烯胺酮类似物N-(3-oxo-5-(三氟甲基)环己-1-en-1-基)-4-(三氟甲基)苯甲酰胺(化合物7),及其在急性癫痫啮齿动物模型中的生物评价。氟化环烷基中间体5-(三氟甲基)环己烷-1,3-二酮(化合物5)和3-氨基-5-(三氟甲基)环己-2-en-1-酮(化合物6)的合成源自一锅水解和酸催化脱羧的改进方法4-叔丁氧基-5-三氟甲基环己烷-1,3-二酮(化合物4)。与我们之前在 6 Hz 44 mA 动物模型中的先导化合物 THA40 相比,Compound7 在 300 mg/kg 的较高剂量下产生药理反应,仅观察到 25% 的保护作用。在最大电击(MES)模型中,compound7 在 100 mg/kg 剂量下表现出中等活性,2 小时后活性为 25%。在 300 mg/kg 的较高剂量下,25% 的动物在 0.5 小时和 2 小时均受到保护。尽管化合物 7 没有产生预期结果,但它为我们在先导化合物优化研究期间提供了新的研究途径。
Enaminone derivatives have been widely studied as potential anticonvulsant agents to treat epilepsy. Our research group is focused on evaluating the anticonvulsant activities of cyclic enaminones connected to a substituted aromatic ring via a sp2hybridized linker. We herein report our lead optimization efforts and the subsequent synthesis of the target fluorinated N-benzamide enaminone analogN-(3-oxo-5-(trifluoromethyl) cyclohex-1-en-1-yl)-4-(trifluoromethyl)benzamide(compound7) from fluorinated intermediates, and its bioevaluation in acute seizure rodent models. The synthesis of the fluorinated cycloalkyl intermediates, 5-(trifluoromethyl) cyclohexane-1,3-dione (compound5) and 3-amino-5-(trifluoromethyl) cyclohex-2-en-1-one (compound6) were derived from an improve method of a one-pot hydrolysis and acid catalyzed decarboxylation of4-carbo-tert-butoxy-5-trifluoromethylcyclohexane-1,3-dione(compound4). Compound7produced pharmacological response at a higher dose of 300 mg/kg with only 25% protection observed, when compared to our previous lead compound THA40 in the 6 Hz 44 mA animal model. In the maximal electroshock (MES) model, compound7showed moderate activity at 100 mg/kg with 25% after 2 h. At a higher dose of 300 mg/kg, 25% of the animals were protected both at 0.5 h and 2 h. Although compound 7 did not produce the expected results, it allowed for a new avenue to investigate during our lead optimization studies.
