N-(gamma-L-Glutamyl)adamantanine (Ic) and N-hydroxyadamantanine (Ib) were synthesized as latentiated forms of the transport-inhibitory alpha-amino acid adamantanine (Ia), and their biological properties were evaluated. Inhibition of the growth of P-388 tumor cells by Ib was comparable with that of the antitumor agent N-hydroxycycloleucine (IIb). In contrast, Ic was inactive in this system, presumably
N-(γ-L-谷氨酰胺基)金刚烷胺(Ic)和N-羟基金刚烷胺(Ib)被合成为运输抑制性α-氨基酸金刚烷胺(Ia)的潜在形式,并对其生物学性质进行了评估。Ib对P-388肿瘤细胞生长的抑制作用与抗肿瘤剂N-羟基环亮氨酸(IIb)的作用相当。相反,Ic在该系统中没有活性,大概是因为它不是γ-谷氨酰转肽酶的底物。然而,这里提出的使用γ-谷氨酰转肽酶来通过药物分子上氨基或羟基的合成γ-谷氨酰化在体内使药物潜伏的概念似乎值得进一步探索。
