The physicochemical properties of 4-substituted carbamazepine derivatives were investigated. It was elucidated that the 4-substitution is not effective in reducing the rotations (E/Z) about the N-C1' axes around the outer carbamoyl moiety. However, the atropisomers were isolated with high stereochemical stability, meaning that the 4-substitution reduced the butterfly motion of the tricyclic ring system
研究了4-取代的卡马西平衍生物的理化性质。阐明了4-取代在减少围绕外部氨基甲酰基部分绕N-C1'轴的旋转(E / Z)方面无效。然而,阻转异构体具有较高的立体化学稳定性,这意味着4-取代可有效降低三环系统的蝶形运动。尽管未观察到对映异构体之间的活性差异,但与卡马西平相比,Cl / CH3取代的卡马西平衍生物对hNav1.2通道电流表现出更大的抑制作用。
