Semisynthetic neoclerodanes as kappa opioid receptor probes [PDF]
Bioorganic & Medicinal Chemistry, 2012 Modification of the furan ring of salvinorin A (1), the main active component of Salvia divinorum, has resulted in novel neoclerodane diterpenes with opioid receptor affinity and activity. Conversion of the furan ring to an aldehyde at the C-12 position (5) has allowed for the synthesis of analogues with new carbon-carbon bonds at that position ...

The G protein-coupled receptor heterodimer network (GPCR-HetNet) and its hub components [PDF]
, 2014 G protein-coupled receptors (GPCRs) oligomerization has emerged as a vital characteristic of receptor structure. Substantial experimental evidence supports the existence of GPCR-GPCR interactions in a coordinated and cooperative manner.

The role of kappa opioid receptors in stress-induced reinstatement of alcohol seeking in rats
Brain and Behavior, 2014 Stress is related to heavy alcohol use and relapse in alcoholics. Using the reinstatement model, we have shown that corticotropin‐releasing factor (CRF) underlies stress‐induced relapse to alcohol seeking in laboratory rodents.

The Kappa Opioid Receptor: From Addiction to Depression, and Back [PDF]
Frontiers in Psychiatry, 2014 Comorbidity is a major issue in psychiatry that notably associates with more severe symptoms, longer illness duration, and higher service utilization. Therefore, identifying key clusters of comorbidity and exploring the underlying pathophysiological mechanisms represent important steps toward improving mental health care.

Interactions of the opioid and cannabinoid systems in reward: Insights from knockout studies
Frontiers in Pharmacology, 2015 The opioid system consists of three receptors, mu, delta, and kappa, which are activated by endogenous opioid peptides (enkephalins, endorphins and dynorphins). The endogenous cannabinoid system comprises lipid neuromodulators (endocannabinoids), enzymes
