Pawhuskin A is a naturally occurring prenylated stilbene isolated from Dalea purpurea which acts as a competitive silent antagonist of the κ-, μ-, and δ-opioid receptors (Ke = 203 nM, 570 nM, and 2900 nM, respectively).[1][2][3] The compound was named after Pawhuska, Oklahoma, a place near where the samples of Dalea purpurea that led to its discovery were taken from.[3] Other isolates of the plant with affinity for opioid receptors include Pawhuskin B and Pawhuskin C, though these compounds produce comparatively weak opioid receptor displacement (4.2–11.4 μM) relative to Pawhuskin A.[1][2] Dalea purpurea was used in traditional Native American medicine to treat various ailments, and pawhuskin A and related isolates may be some of the constituents of the plant which underlay this use.[2]
