Some glycine, leucine and phenylalanine dipeptide derivatives of the transport inhibitory, tricycloaliphatic alpha-amino acid, adamantanine (1), have been synthesized using classical methods of peptide synthesis with the aim of improving the latter's bioavailability. Although test doses of glycyladamantanine and L-leucyladamantanine appeared to be absorbed in vivo as evidenced by its appearance in
已经使用经典的肽合成方法合成了运输抑制性三环脂族α-氨基酸金刚烷(1)的一些甘氨酸,亮氨酸和苯丙氨酸二肽衍生物,目的是提高后者的生物利用度。尽管测试剂量的糖基金刚烷胺和L-亮氨酰金刚烷胺似乎在体内被吸收,如腹膜内给药后其在尿中的出现所证明的那样,但它们并未在体外被亮氨酸氨基肽酶的纯化制剂水解。实际上,它们是该酶的抑制剂。金刚烷基甘氨酸,金刚烷基-L-亮氨酸和金刚烷基-L-苯丙氨酸也不能被亮氨酸氨基肽酶水解。
