Abstract

L'invention concerne des composés tels que représentés par la formule i ou i' et des sels, solvates, et diastéréoisomères pharmaceutiquement acceptables de ceux-ci : dans laquelle r1, r2, r2a, r3, et r4 sont tels que définis dans la description. L'invention concerne également des composés de formules ii, iii, a a-h et des sels, solvates et diastéréoisomères pharmaceutiquement acceptables de ceux-ci. Dans certains modes de réalisation, les composés de l'invention sont utiles pour le traitement de la douleur, de la constipation, et d'autres pathologies comme le souligne la description. Sans souhaiter être lié par une quelconque théorie, on pense que les composés de l'invention sont efficaces dans le traitement de pathologies qui sont modulées par l'activité de récepteurs opioïdes et/ou orl-1.
