pharmacokinetic characteristics, a series of GLP-2 analogues containing Gly substitution at position 2, norleucine in position 10, and hydrophobic substitutions in positions 11 and/or 16 was designed and synthesized. In vitro receptor potency at the human GLP-2, selectivity vs the human GLP-1 and GCG receptors, and PK profile in rats were determined for the new analogues. A number of compounds more potent at the
胰高血糖素样肽2受体激动剂具有治疗肠道疾病的潜力。天然的hGLP-2是一种33个氨基酸的胃肠道肽,由于其在人体内的半衰期非常短,因此不适合作为临床候选药物。为了寻找具有更好的药代动力学特性的GLP-2受体激动剂,设计并合成了一系列GLP-2类似物,其在2位,2位正亮氨酸,10位和11位和/或16位疏水取代含有甘氨酸取代。体外确定了新的类似物对人GLP-2的效价,对人GLP-1和GCG受体的选择性以及大鼠的PK谱。已发现许多在hGLP-2R上比天然激素更有效的化合物,表现出出色的受体选择性和非常低的全身清除率(CL)。类似物69([Gly 2,Nle 10,d -Thi 11,Phe 16 ] hGLP-2-(1-30)-NH 2),72([Gly 2,Nle 10,d -Phe 11,Leu 16 ] hGLP -2-(1-33)-OH),73([Gly 2,Nle 10,d -Phe 11,Leu
