Design and development of novel, short, stable dynorphin-based opioid agonists for safer analgesic therapy

open access: yesFrontiers in Pharmacology, 2023
Kappa opioid receptors have exceptional potential as an analgesic target, seemingly devoid of many problematic Mu receptor side-effects. Kappa-selective, small molecule pharmaceutical agents have been developed, but centrally mediated side-effects limit ...

Opioid Peptides: Potential for Drug Development [PDF]

open access: yes, 2012
Opioid receptors are important targets for the treatment of pain and potentially for other disease states (e.g. mood disorders and drug abuse) as well.

A review of frequently used Kampo prescriptions part 1. Daikenchuto

open access: yesTraditional &Kampo Medicine, Volume 9, Issue 3, Page 151-179, December 2022., 2022
Abstract Background The original formula name for daikenchuto (DKT) was written in ‘Jin Gui Yao Lue (Kinkiyōryaku in Japanese)’. DKT as used in Japan consists of four types of crude drug. Key findings Although there are few examples of its use in Chinese classical records, it has begun to be used extensively in modern Japan for intestinal obstruction ...

Towards the convergent therapeutic potential of G protein‐coupled receptors in autism spectrum disorders

open access: yesBritish Journal of Pharmacology, EarlyView., 2023
Abstract Autism spectrum disorders (ASDs) are diagnosed in 1/100 children worldwide, based on two core symptoms: deficits in social interaction and communication, and stereotyped behaviours. G protein‐coupled receptors (GPCRs) are the largest family of cell‐surface receptors that transduce extracellular signals to convergent intracellular signalling ...

Concomitant duplications of opioid peptide and receptor genes before the origin of jawed vertebrates. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: The opioid system is involved in reward and pain mechanisms and consists in mammals of four receptors and several peptides. The peptides are derived from four prepropeptide genes, PENK, PDYN, PNOC and POMC, encoding enkephalins, dynorphins ...

Heteromerization of μ-opioid receptor and cholecystokinin B receptor through the third transmembrane domain of the μ-opioid receptor contributes to the anti-opioid effects of cholecystokinin octapeptide

open access: yesExperimental and Molecular Medicine, 2018
Pain medicine: Boosting the potency of opioid analgesics A hormone known to weaken the pain-relieving effects of opioid drugs does so because of interaction between the hormone receptor and the opioid receptor.
