• Phenylalanine derivatives enhancing intestinal absorption of insulin in mice.

  DOI：10.1248/cpb.36.4426

  日期：——

  The adjuvant effect of N-acyl-L-and D-phenylalanine derivatives on intestinal absorption of insulin was investigated in normal mice. The correlation between the chemical structural properties of the N-acyl moiety and the absorption-promoting activity was estimated from the glucose concentrations and the insulin levels in the blood of mice after oral combined administration of insulin and adjuvant. The chemical structural properties of N-acyl-phenylalanine derivatives necessary for adjuvant effect on intestinal absorption of insulin were as follows. 1. An aromatic ring is present, separated by two atoms from the acyl carbonyl group. 2. Either of X or Y is oxygen or X-Y is a double bond in Fig.2. 3. The N-acyl moiety has small hydrophobic substituents, such as F, Cl, or Me at Rα, Rβ, Rη and has an appropriate hydrophilic-hydrophobic balance of the overall molecule. The use of these agents to enhance insulin absorption offers the possibility of a new approach to oral insulin therapy.

  研究了N-酰基-L-和D-苯丙氨酸衍生物对正常小鼠胰岛素肠道吸收的辅助效应。根据小鼠口服胰岛素和辅料联合给药后的血糖浓度和胰岛素水平，推测了N-酰基部分的化学结构性质与促吸收活性之间的相关性。N-酰基-苯丙氨酸衍生物对胰岛素肠道吸收具有辅效应的化学结构性质如下：1. 芳环存在，与酰基羰基相隔两个原子。2. 图2中的X或Y之一为氧，或者X-Y是双键。3. N-酰基部分具有较小的疏水取代基，如F、Cl或Me在Rα、Rβ、Rη位置，并且整个分子具有适当的亲水-疏水平衡。利用这些制剂增强胰岛素吸收，为口服胰岛素治疗提供了新的途径。
