that the steric size of constraints added to the pyroglutamate region of TRH (pGluHisProNH(2)) can be varied. Both an analogue with a smaller ethylene bridge and a larger, more flexible propane bridge in this region have been synthesized. These analogues were synthesized in order to probe why the initial incorporation of an ethane bridge into this region of the molecule had led to an analogue with a binding
已经开发了一种改良的合成路线,以便可以改变添加到TRH的焦谷氨酸区域(pGluHisProNH(2))的限制位的空间大小。合成了在该区域具有较小乙烯桥和较大,更灵活的丙烷桥的类似物。合成这些类似物是为了探究为什么最初将乙烷桥掺入分子的该区域会导致其结合常数和效能比直接类似的无约束类似物低三倍的类似物。两种类似物的数据均表明,初始类似物中由乙烷桥引起的活性下降不是由桥的大小引起的。
