Our OPTI-SAFETY Panel consists of clinically-relevant transporters that are implicated in diseases and serious adverse drug reactions (ADR). Transporters in the panel can be used to identify potential safety problems, and either eliminate dangerous compounds early in the development process, or mitigate risks by understanding the mechanisms and potential clinical safety issues. We provide customized OPTI-SAFETY Panel research services for rapid screening or comprehensive, mechanistic profiling studies.

Transporter proteins regulate the movement of numerous critical nutrients and signaling molecules, such as amino acids, monosaccharides, bile salts and neurotransmitters. Serious side effects, such as brain excitotoxicity, liver cholestasis, cardiac myopathy and type II diabetes, can be attributed to the unexpected modulation of transporters by pharmaceuticals, leading to expensive clinical failures and drug withdrawals. To help reduce safety-related attrition rates, it is important to evaluate a compound’s effect on transporters that are important modulators of key physiological processes.

The table below lists transporters that are associated with serious adverse events.
