Species-specific pharmacology of maximakinin, an amphibian homologue of bradykinin: putative prodrug activity at the human B2 receptor and peptidase resistance in rats [PDF]

open access: yesPeerJ, 2017
Maximakinin (MK), an amphibian peptide possessing the C-terminal sequence of bradykinin (BK), is a BK B2 receptor (B2R) agonist eliciting prolonged signaling.

Cyanide Beyond Toxicity: A Systematic Review of Its Effects on Vascular Function

open access: yesBasic &Clinical Pharmacology &Toxicology, Volume 137, Issue 5, November 2025.
ABSTRACT Cyanide is widely recognized for its potent toxicity, yet evidence shows that concentrations below 1 μM may enhance cytochrome c oxidase activity and have a regulatory function. Recent findings also demonstrate that mammalian cells, including endothelial cells, produce cyanide endogenously, where it can modulate mitochondrial bioenergetics ...

Synergistic interaction between Diclofenac and Pyrilamine on nociception, inflammation and gastric damage in rats

open access: yes, 2016
Experiments using non-steroidal anti-inflammatory drugs (NSAIDs) alone have produced limited antinociceptive effects in animal models. For this reason, the number of studies involving the administration of NSAIDs along with an adjuvant drug harboring ...

Association of Inpatient Prescribing of First‐Generation Antihistamines With Delirium in Older Adults: A Cross‐Sectional Study

open access: yesJournal of the American Geriatrics Society, Volume 73, Issue 11, Page 3475-3483, November 2025.
ABSTRACT Background Small studies have reported associations between first‐generation antihistamines and delirium. It is unclear whether first‐generation antihistamines cause clinically important delirium among older adult inpatients. Objective To estimate the association between inpatient physician prescribing of first‐generation antihistamines and ...

Analysis of histamine as a hair-cell transmitter in the lateral line of Xenopus laevis [PDF]

open access: yes, 1989
The actions of histamine and histamine antagonists on afferent nerve activity were investigated in the lateral line of Xenopus laevis. Histamine (0.002-2.0 mM) had no effect on spontaneous activity or excitatory responses to water motion.

Decoding Pain: Next‐Generation In Vitro Systems for Mechanistic Insights and Drug Discovery

open access: yesThe FASEB Journal, Volume 39, Issue 16, 31 August 2025.
Developing an in vitro pain model that mimics essential features of the in vivo pain circuit requires careful consideration of multiple components and choices. These include selecting the cellular population for the model, choosing from the origin of nociceptors and other cells that are cultured, deciding between 3D or 2D dimensions, designing the ...

Involvement of the pyrilamine transporter, a putative organic cation transporter, in blood-brain barrier transport of oxycodone

open access: yes, 2008
The purpose of this study was to characterize blood-brain barrier (BBB) transport of oxycodone, a cationic opioid agonist, via the pyrilamine transporter, a putative organic cation transporter, using conditionally immortalized rat brain capillary ...

The effects of histaminergic agents in the nucleus accumbens of rats in the elevated plus-maze test of anxiety.

open access: yesIranian Journal of Psychiatry, 2010
Objective: The nucleus accumbens (NAc) receive histaminergic neurons from tuberomammillary nuclei. There are reports indicating that central histamine systems are involved in many physiological behavioral processes, including anxiety.

Disruption of histamine/H1R signaling pathway represses cardiac differentiation and maturation of human induced pluripotent stem cells

open access: yesStem Cell Research & Therapy, 2020
Background The efficiency and quality of human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) are crucial for regenerative medicine, disease modeling, drug screening, and the study of the development events during cardiac specification.
