Three analogs of thyroliberin (I) were prepared. These compounds, N-m-chloroacetylbenzoyl-phenylalanyl-prolineamide (VIa), N-p-chloroacetylbenzoyl-phenylalanyl-prolineamide (VIb) and N-chloroacetyl-alanyl-phenylalanyl-prolineamide (IX), were designed as potential I antagonist affinity labels. However, no significant antagonist activity was observed. Compounds VIa and IX were found to have weak agonist
制备了三种甲状腺素(I)类似物。这些化合物Nm-氯乙酰基苯甲酰基-苯丙氨酰-脯氨酸(VIa),Np-氯乙酰基苯甲酰基-苯丙氨酰-脯氨酸(VIb)和N-氯乙酰基-苯丙酰基-苯丙氨酰-脯氨酸(IX)被设计为潜在的I拮抗剂亲和标记。但是,没有观察到明显的拮抗剂活性。发现化合物VIa和IX具有弱的激动剂活性。然而,发现环(Phe-Pro)是I代谢产物的类似物,环(His-Pro)具有明显的I拮抗剂活性,但没有激动剂活性。
