Design and validation of recombinant protein standards for quantitative Western blot analysis of cannabinoid CB1 receptor density in cell membranes: an alternative to radioligand binding methods

open access: yesMicrobial Cell Factories, 2022
Background Replacement of radioligand binding assays with antibody-antigen interaction-based approaches for quantitative analysis of G protein-coupled receptor (GPCR) levels requires the use of purified protein standards containing the antigen.

Validation of a [3H]Astemizole Binding Assay in HEK293 Cells Expressing HERG K+ Channels

open access: yesJournal of Pharmacological Sciences, 2004
A radioligand binding assay for the HERG (human ether-a-go-go-related gene) K+ channel was developed to identify compounds which may have inhibitory activity and potential cardiotoxicity.

Functional Authentication of a Novel Gastropod Gonadotropin-Releasing Hormone Receptor Reveals Unusual Features and Evolutionary Insight. [PDF]

open access: yesPLoS ONE, 2016
A gonadotropin-releasing hormone (GnRH)-like molecule was previously identified in a gastropod, Aplysia californica, and named ap-GnRH. In this study, we cloned the full-length cDNA of a putative ap-GnRH receptor (ap-GnRHR) and functionally authenticated

A radioligand binding assay for the insulin-like growth factor 2 receptor.

open access: yesPLoS ONE, 2020
Insulin-like growth factors 2 and 1 (IGF2 and IGF1) and insulin are closely related hormones that are responsible for the regulation of metabolic homeostasis, development and growth of the organism.

A Scintillation Proximity Assay for Real-Time Kinetic Analysis of Chemokine–Chemokine Receptor Interactions

open access: yesCells, 2022
Chemokine receptors are extensively involved in a broad range of physiological and pathological processes, making them attractive drug targets. However, despite considerable efforts, there are very few approved drugs targeting this class of seven ...

Artificial tissue binding models : development and comparative evaluation of high - throughput lipophilicity assays and their use for PET tracer optimization [PDF]

open access: yes, 2015
The purpose of this thesis was to increase the efficiency of the Positron Emission Tomography (PET) tracer development process. Since many neuroimaging agents fail due to undesirably high non-specific binding (NSB) to brain tissue, we aimed at estimating

Characterization of muscarinic receptor binding by the novel radioligand, [3H]imidafenacin, in the bladder and other tissues of rats

open access: yesJournal of Pharmacological Sciences, 2016
The present study aimed to directly characterize specific binding sites of tritium ([3H])-labeled imidafenacin, a new radioligand for labeling muscarinic receptors, in the bladder and other peripheral or central nervous tissues of rats.

Discovery of novel dual adenosine A1/A2A receptor antagonists using deep learning, pharmacophore modeling and molecular docking.

open access: yesPLoS Computational Biology, 2021
Adenosine receptors (ARs) have been demonstrated to be potential therapeutic targets against Parkinson's disease (PD). In the present study, we describe a multistage virtual screening approach that identifies dual adenosine A1 and A2A receptor ...

DESIGN AND SYNTHESIS OF A PIPERAZINE DERIVATIVE AS A HIGH AFFINITY 5-HTIA RECEPTOR LIGAND

open access: yesZagazig Journal of Pharmaceutical Sciences, 1993
Serotonin (5-HT) 1A receptors have been shown to have physiological, biochemical pharmacological and clinical values. The piperazino derivative 1 was rationally designed as a bulky, lipophilic N4-substituted arylpiperazine. Radioligand binding assay of 1
