| (what is this?)
Phenomorphan is a highly potent drug due to the N-phenethyl group, which boosts affinity to the μ-opioid receptor, and so phenomorphan is around 10x more potent than levorphanol, which is itself 6-8x the potency of morphine. Other analogues where the N-(2-phenylethyl) group has been replaced by other aromatic rings. are even more potent, with the N-(2-(2-furyl)ethyl) and the N-(2-(2-thienyl)ethyl) analogues being 60x and 45x stronger than levorphanol, respectively.
