the decarboxyl derivative, the esters, and the amides of the phenylalanine derivatives. Thus, the structural requirements for possessing hypoglycemic activity was elucidated and a highly active compound, N-[(trans-4-isopropylcyclohexyl)carbonyl]-D-phenylalanine (13) was obtained, which showed a 20% blood glucose decrease at an oral dose of 1.6 mg/kg in fasted normal mice.
已经合成了一系列N-(环己基羰基)-
D-苯丙氨酸的类似物(5),并评估了它们的降血糖活性。研究了酰基部分的活性与三维结构之间的关系,该关系通过高分辨率1H NMR光谱学和MNDO计算来表征。还通过比较苯丙
氨酸衍
生物的对映异构体,脱羧衍
生物,酯和酰胺的活性,研究了苯丙
氨酸部分的羧基的作用。因此,阐明了具有降血糖活性的结构要求,并获得了高活性化合物N-[(反式-4-异丙基环己基)羰基] -
D-苯丙氨酸(13),其口服后血糖降低了20%。禁食正常小鼠的最大剂量为1.6 mg / kg。
