CYP450 Inhibition

Fast, Accurate and Affordable

Whether you’re tight on budget, time, or internal capacity, Analiza offers a CYP450 inhibition study to meet your discovery needs. We understand that different therapeutic areas and programs have different needs so we’ll work with you to identify the right screening strategy for you; maximizing your budget while enabling you to identify compound liabilities in real time.

For initial screening, single inhibitor concentration provides relevant outcomes and is ideal for early discovery. However, if the IC50 values are much smaller or larger than the concentration tested it may difficult to distinguish between Time dependent Inhibition (TDI) and direct inhibition. With 3A4 responsible for the vast majority of clinically relevant drug-drug interactions, Analiza offers single point and 7 pt. IC50 CYP3A4 TDI studies.
