Transporter Screening Applications
In vitro transporter assays are an integral part of the drug discovery and development process. Many transporters are validated or emerging as therapeutic targets for a variety of diseases, including depression, schizophrenia, cancer, and diabetes. Therefore, compound screening against transporter targets (e.g. SERT, DAT, NET, and SGLT2) is essential for the discovery of potent and selective therapeutic candidates. Transporter studies are also routinely conducted for development-stage compounds for assessing drug-drug interaction (DDI), clinical safety, and commercial viability. For transporters such as P-gp, OATP1B1, and BSEP that are associated with life-threatening DDIs and adverse effects, such tests are often performed at discovery stage for earlier identification of compounds with issues in clinical safety and commercial viability. In addition, many organizations are employing transporter-conscious drug design, which utilizes transporters such as PEPT1, OATP1B1, and xCT to improve drug bioavailability, tissue selectivity and disease targeting. Taken together, transporter screening is an invaluable tool in drug discovery that enables researchers to design and optimize lead compounds with novel therapeutic actions, and more desirable pharmacokinetic and clinical safety profiles.
Considerations on Implementing Transporter Screening Projects
A key requirement of transporter screening campaigns is robust functional assays with good signal-to-background ratios and Z’ scores. All of Optivia’s assays employ direct measurement of transporter functional activity, which provides more biologically-relevant results in comparison to indirect binding assays. These robust, validated assays have been extensively in regulatory-compliant transporter studies for clinical- stage compounds, they are also suitable for early-stage screening due to their strong Z’ scores. Our robust assays and extensive experience enable rapid delivery of high-quality screening data, making it easier for clients to identify true modulators of a variety of transporters.
