The structure-activity relationship of the O-benzyl serine side chain was investigated based on the tetrazole-based growth hormone secretagogue BMS-317180 (2). The ortho position of the benzyl moiety was found to be favorable for introduction of substituents. A series of ortho-substituted compounds were synthesized with improved in-vitro and in-vivo activity. Among them, the biphenyl compound 2p shows twofold improvement in potency compared to its parent compound BMS-317180 (2).
基于四氮唑类生长激素促分泌剂BMS-317180（2），对O-苄基丝氨酸侧链的构效关系进行了研究。发现苄基部分的邻位有利于引入取代基。合成了一系列邻位取代的化合物，其体外和体内活性均有所提高。其中，联苯化合物2p与其母体化合物BMS-317180（2）相比，效价提高了两倍。
