GPCR scanLibrary

In contrast to the traditional drug discovery model where a target is nominated on the basis of biology and screened against a compound library for putative hits in a single-target high-throughput (HTS) screening campaign, GPCR scanLIBRARY affords researchers the ability to screen an entire compound library against multiple biological targets of interest simultaneously.

As the development of novel GPCR-targeted drugs continues to expand into multiple therapeutic areas, safety and selectivity data will become even more vital. A fully profiled library has a defined ‘footprint’ across the entire family of GPCRs. Knowledge of which targets can or cannot be accessed with the current chemistry reduces the likelihood of pursuing programs ill-suited to achieve the clinical candidate profile. Likewise, compounds that display an array of selectivity patterns that may not only reveal new clinical applications but may also serve as ‘tool’ compounds for investigating activity in vivo. And with the re-emergence of phenotypic screens, GPCR scanLIBRARY provides an opportunity to uncover potent and selective compounds with minimal knowledge about the target receptor and mode of action and these high quality lead like compounds can be used to initiate lead optimization programs.

High Quality Starting Point From Library Profiling

In contrast to the traditional and largely linear GPCR discovery model in which one GPCR target is assessed at a time, GPCRscan affords the unprecedented ability to comprehensively annotate entire compound collections against a large number of GPCRs.  This highly parallel approach enables organizations to identify multiple targets of interest, defined by target biology, for which high quality lead like compounds exist and to focus resources on those programs most likely to succeed.

Data Analysis & Interpretation 


Percent Activity/Inhibition

The results for single concentration (primary screen) for tested compound(s) are reported in your study report and spreadsheets as '% Activity' or '% Inhibition' and are calculated in the following manner:

% Activity
(Agonist Mode) =
100% x
Mean RLU (test sample)- Mean RLU(vehicle control)

Mean MAX RLU (control ligand)- Mean RLU (vehicle control)

test sample = client supplied compound
vehicle control = DMSO (0% activity)
control ligand = control compound (100% activity)


% Inhibition
(Antagonist mode) =
100% x
[ 1- 
Mean RLU (test sample)- Mean RLU(vehicle control)

Mean MAX RLU (control ligand)- Mean RLU (vehicle control)

test sample = client supplied compound
vehicle control = DMSO (0% activity)
EC80 control = control compound (80% activity) 


Dose Response Curve (EC50/IC50)

The results for 10-point dose response curve compound/target interactions are reported in the study report and spreadsheets as EC50/IC50, which are values derived using the Hill equation:
