Analogues of [Dmt1]DALDA (H-Dmt-d-Arg-Phe-Lys-NH2; Dmt = 2′,6′-dimethyltyrosine), a potent μ opioid agonist peptide with mitochondria-targeted antioxidant activity were prepared by replacing Dmt with various 2′,6′-dialkylated Tyr analogues, including 2′,4′,6′-trimethyltyrosine (Tmt), 2′-ethyl-6′-methyltyrosine (Emt), 2′-isopropyl-6′-methyltyrosine (Imt) and 2′,6′-diethyltyrosine (Det). All compounds
[Dmt 1 ] DALDA(H-Dmt- d -Arg-Phe-Lys-NH 2; Dmt = 2',6'-二甲基酪氨酸)的类似物,通过替代线粒体,制备了具有线粒体靶向抗氧化剂活性的有效μ阿片类激动剂肽具有各种2',6'-二烷基化Tyr类似物的Dmt,包括2',4',6'-三甲基酪氨酸(Tmt),2'-乙基-6'-甲基酪氨酸(Emt),2'-异丙基-6'-甲基酪氨酸(Imt)和2',6'-二乙基酪氨酸(Det)。所有化合物均为选择性μ阿片样物质激动剂,并且TMT 1-,Emt 1和Det 1-类似物显示亚纳摩尔μ阿片样物质受体结合亲和力。TMT的1 -和EMT 1个-analogues显示改善的抗氧化活性比DMT 1-亲本肽在DPPH自由基清除能力测定中的应用,因此作为神经性疼痛治疗的候选药物而受到关注。
