Publikováno v: Bulletin des Sociétés Chimiques Belges. 99:849-856
Within the scope of the study of structure-activity relationships of opioids, we examined some conformational aspects of the rotation of the 7α-substituent in ethenoisomorphinan peptides. Using molecular mechanics (MMX88) we have determined the rela
