Quantitate compound potency against any PATHscan functional cell-based assay. Agonist half maximal effective concentrations (EC50s) and antagonist half maximal inhibitory concentrations (IC50s) are calculated from duplicate 10-point dose-response curves. Measurements are made under optimized conditions to generate consistent and reproducible data that reliably reflects the drug’s potency.

pathE/IC50ELECT may be used as an ideal follow-up study tool to quantify the potency of compound-kinase target interactions identified in primary screens, to supplement existing data, or support lead optimization and SAR activity.

Data Analysis & Interpretation 

What does the term EC50 mean?

The term half maximal effective concentration (EC50) refers to the concentration of a drug or biologic which induces a response halfway between the baseline and the maximum. Therefore, the EC50 of a compound or biologic represents the concentration where 50% of it’s maximal effect can be observed. It is commonly used as a measure of the drug’s potency.

What does an IC50 measure?

The term half maximal inhibitory concentration (EC50) is a measure of the effectiveness of a compound to inhibit a given biological response. Therefore, the IC50 of a compound or biologic represents the half maximal (50%) inhibitory concentration and is commonly used as a measure of antagonist drug’s potency.

How are the EC50/IC50s calculated?

For each compound/GPCR target interaction, dose response curves  are generated using 10 concentrations of agonist or antagonist (10-point curve). The results are reported as EC50/IC50 which derived using the Hill equation:
