1 To overcome metabolic instability and poor membrane permeability, the N- and C-termini of Endo-1 were modified by lipoamino acids (Laa) and/or sugars, and 2",6"-dimethyltyrosine (Dmt) replacement of Tyr. 2',6'-dimethyltyrosine ENDO1 Homo sapiens
2 To overcome metabolic instability and poor membrane permeability, the N- and C-termini of Endo-1 were modified by lipoamino acids (Laa) and/or sugars, and 2",6"-dimethyltyrosine (Dmt) replacement of Tyr. 2',6'-dimethyltyrosine ENDO1 Homo sapiens
3 Dmt provided a promising lead compound: [C8Laa-Dmt[1]]-Endo-1 is nine times more stable (t(1/2)=43.5min), >8-fold more permeable in Caco-2 cell monolayers, and exhibits 140-fold greater mu-opioid receptor affinity (K(imu)=0.08nM). 2',6'-dimethyltyrosine ENDO1 Homo sapiens
