Two‐Step Synthesis of Enantiomerically Pure Morphans from (R)‐Carvone
A two‐step procedure transformed the natural product (R)‐carvone into enantiomerically pure morphans allowing selective modifications at 2‐, 4‐ and 6/7‐position. Whereas affinity towards opioid receptors could not be detected, nanomolar σ1 affinity was found for indolomorphans and quinolinomorphans.

Bivalent and bitopic ligands of the opioid receptors: The prospects of a dual approach
Abstract Opioid receptors belonging to the class A G‐protein coupled receptors (GPCRs) are the targets of choice in the treatment of acute and chronic pain. However, their on‐target side effects such as respiratory depression, tolerance and addiction have led to the advent of the ‘opioid crisis’.

Abstract Background Over the past 25 years, global opioid consumption has increased. Denmark ranks fifth in opioid use globally, exceeding other Scandinavian countries. Postsurgical pain is a common reason for opioid prescriptions, but opioid use patterns after patient discharge from the hospital are unclear.

Herein, a chromosome‐level genome assembly of Menispermum dauricum is presented. A novel MdCYP80G10 enzyme is identified to catalyze C2′‐C4a phenol coupling of (S)‐reticuline into sinoacutine, the enantiomer of morphinan compounds, with predictable stereospecificity.

Photo‐affinity and Metabolic Labeling Probes Based on the Opioid Alkaloids
Leon Duque, Vallavoju, and colleagues report the design and development of photo‐affinity and metabolic labeling probes based on the opioid alkaloids. These chemical probes are used to measure localization and protein interactions in a cellular context by confocal microscopy and chemical proteomics.

Synthesis of Alkaloids and Compounds Containing the 3,4‐Benzomorphan Scaffold
This review summarizes the biosynthesis and the synthesis of several biologically active natural compounds (i. e., alkaloids) and other related compounds containing the hexahydro‐2,6‐methano‐1‐benzazocine structure (i. e., 3,4‐benzomorphan scaffold). Abstract Several natural products, bearing an embedded hexahydro‐2,6‐methano‐1‐benzazocine framework (3,

Trajectories of sentiment in 11,816 psychoactive narratives
Abstract Objective Can machine learning (ML) enable data‐driven discovery of how changes in sentiment correlate with different psychoactive experiences? We investigate by training models directly on text testimonials from a diverse 52‐drug pharmacopeia. Methods Using large language models (i.e.
