amino ketones with an aza-glycine equivalent, chemoselective nitrogen functionalization, and ring closure. Several mimics exhibited selective modulatory effects on hUII- and URP-associated vasoconstriction in an ex vivo rat aortic ring bioassay. The C5p-hydroxyphenethenyl benzotriazepin-2-one 20g decreased hUII potency and efficacy without changing URP induced vasoconstriction. Its saturated phenethyl
苯并三氮杂-2-酮被设计为模仿拟尿素中的Bip-Lys-Tyr三肽([Bip 4 ] URP)的建议的生物活性γ-转构象,该构象可调节urotensin II受体(UT)并区分内源性的影响配体urotensin II(UII)和urotensin II相关肽(URP)。通过将邻氨基苯甲酸衍生的氨基酮与氮杂甘氨酸等效物进行酰化,化学选择性氮官能化和闭环合成了二十六个苯并三氮杂-2-酮。几种模拟物在离体大鼠主动脉环生物测定中显示出对hUII和URP相关血管收缩的选择性调节作用。C 5对羟基苯基乙烯基苯并三氮杂-2-酮20g降低了hUII的效力和功效,而没有改变URP诱导的血管收缩。它的饱和苯乙基对应物23g在不影响hUII介导的收缩的情况下降低了URP效能。据我们所知,20g和23g代表第一个选择性调节hUII和URP生物活性的非手性分子。有效合成的苯并三氮杂-2-酮转向模拟物提供了区分UT系
