title: The design and synthesis of a novel quinolizidine template for potent opioid and opioid receptor-like (ORL1, NOP) receptor ligands.
abstract: A new class of high affinity opioid and opioid receptor-like receptor (ORL1 receptor, NOP receptor) ligands has been designed by conformational restriction of piperidine-based NOP receptor ligands, resulting in a novel quinolizidine scaffold. Different modifications of the pendant functional groups on the scaffold provide differential activities at the opioid and NOP receptors. While the conformational rigidity will provide an improved understanding of the NOP and opioid receptor binding pockets, these compounds also provide a new template for the design of novel opiate and NOP ligands.
