from the C(2) site. This paper validates this hypothesis. Twelve derivatives of N-benzyl-2-acetamidopropionamide have been prepared in which six different heteroatom substituents (chloro, bromo, iodo, oxygen, nitrogen, and sulfur) were incorporated at the C(3) site. Highly potent activities were observed for the two oxygen-substituted derivatives, N-benzyl-2-acetamido-3-methoxypropionamide (18) and N
研究表明2-取代的N-苄基-2-乙酰氨基乙酰胺(2)是有效的抗惊厥药。最近的研究导致了这样一个假设:最大的抗惊厥活性在2中的重要结构特征是从C(2)位置一个原子取代了一个小的取代杂原子部分。本文验证了这一假设。N-苄基-2-乙酰氨基丙酰胺的十二种衍生物已被制备,其中六个不同的杂原子取代基(氯,溴,碘,氧,氮和硫)被引入到C(3)位。对于两种氧取代的衍生物,N-苄基-2-乙酰氨基-3-甲氧基丙酰胺(18)和N-苄基-2-乙酰氨基-3-乙氧基丙酰胺(19),观察到了很强的活性。腹膜内(ip )18和19的最大电击诱发癫痫试验的剂量分别为8.3和17.3 mg / kg。这些值优于苯妥英钠的ED50值(ED50 = 6.5 mg / kg)。口服(po)给予大鼠后观察到18和19具有可比的活性(18,ED50 = 3.9 mg / kg; 19,ED50 = 19 mg / kg;苯妥英,ED50
