A dipeptide named kyotorphin, H-Tyr-Arg-OH, and its retro isomer were synthesized using NG-mesitylene-2-sulfonylarginine. Two corresponding stereoisomers containing D-Arg were also synthesized. Among these, H-Tyr-D-Arg-OH was found to possess an analgesic effect 6 times higher than that of the corresponding L-isomer.
使用NG-均三甲苯-2-磺酰精氨酸合成了名为kyotorphin、H-Tyr-Arg-OH 的二肽及其逆向异构体。还合成了两种相应的含有D-Arg 的立体异构体。其中,H-Tyr-D-Arg-OH的镇痛效果比相应的L-异构体高6倍。
