Synthesis and evaluation of 2-amino-8-alkoxy quinolines as MCHr1 antagonists. Part 3.

Prior SAR studies on 2-amino-8-alkoxyquinoline MCHr1 antagonists demonstrated that compounds with acyclic amide-containing sidechains displayed exceptional binding and functional potency, but negligible CNS penetration. Related analogs with acyclic benzylamine-containing sidechains showed greatly improved CNS exposure, but suffered in functional potency. In… CONTINUE READING
