The ADME properties of therapeutic peptides and proteins have been improved significantly and bio-therapeutic drugs have gained importance in the treatment of critical diseases. As in small molecule drug development there is a need to understand their bio-transformations to ensure that the molecule is safe and efficacious and does not cause toxicity. The ability to find, identify and confirm catabolites as quickly as possible is critical at multiple stages of drug discovery and development. Advancements in accurate mass instrumentation such as the TripleTOF® 6600 have enabled the generation of very information rich raw data but new software to automate the catabolite identification workflow is required to benefit drug metabolism researchers. To address this need SCIEX has introduced the new MetabolitePilotTM 2.0 software that includes a dedicated peptide catabolism workflow.

In this tech note the in-vitro metabolism of a model therapeutic peptide Bivalirudin was investigated to highlight the new peptide catabolism workflow features of MetabolitePilot 2.0 software.
