6-bis(4-aminobutyl)-5-methyl-2(1H)-pyrazinone (15). Using above pyrazinone derivatives, three opioid mimetics were prepared (III-V). Derivatives containing 3 and 6 demonstrated weak μ and δ-opioid receptor affinities ranging from 1.6 mM to 4.1 mM while the opioid mimetic containing derivative 15 displayed higher μ-opioid receptor binding affinity (Kiμ = 61 nM) and selectivity ().
二肽基氯甲基酮的环化得到6-(4-氨基丁基)-3-羧乙基-5-甲基-2(1 H)-吡嗪酮(3),3-(4-氨基丁基)-6-羧乙基-5-甲基-2 (1 H)-吡嗪酮(6)和3,6-双(4-氨基丁基)-5-甲基-2(1 H)-吡嗪酮(15)。使用上述吡嗪酮衍生物,制备了三种阿片样物质模拟物(III-V)。含衍生物3和6证实弱μ和δ阿片样物质受体的亲和力范围从1.6mm至4.1mm的,而阿片样物质模拟物含有衍生物15显示更高的μ阿片受体结合亲和性(ķ我μ= 61 nM)和选择性()。
