Where Does Bioanalysis Fit into Drug Discovery Pipelines?

BY

The drug design and development industry relies on effective, reliable, and robust analytical methods to assess the efficacy and safety of potential drug candidates. Bioanalysis is foundational for investigational therapeutic agents. It helps drug developers evaluate various properties of potential drugs, providing evidence on whether to move to clinical trials in humans and eventually to the commercial market. Specifically, the bioanalysis of various molecules is helpful in the multi-step drug development process as it can reveal valuable pharmacological and toxicological dynamics when the molecule is present in a biological environment. This blog post will define the bioanalysis of molecules and highlight its beneficial role in drug discovery pipelines.

Conducting Bioanalysis in Drug Discovery and Development

Bioanalysis is conducted in multiple steps to quantify drugs and their metabolites. First, preparation of the sample must occur, and then detection of the target compounds is executed, typically using the reliable method of mass spectrometry [1]. Liquid chromatography is generally used in tandem with mass spectrometry to amplify performance and data extracted from experiments.

Large molecules such as proteins are often used in drug design. They are larger on a molecular level and more complex than small molecules, requiring specific bioanalysis methods to be properly assessed in various ways [2]. Large molecule methods reveal valuable information about protein dynamics and biochemical reactions in living organisms crucial to drug development strategies.

Ligand binding assays are a common type of bioanalysis used to assess large molecules and quantify data from a biological molecule reacting with another biological analyte or reagent necessary for drug design [2,3]. Highly sensitive, ligand binding assays can detect low levels of target molecules. This method can further be amplified by technologies that measure the kinetics of molecules in real time so an investigation can be conducted into various binding interactions that give insight into how a drug would potentially act in a biological system [3].

Immunogenicity testing is another form of large molecule bioanalysis, referring to drug-induced antibody response monitoring. This type of assessment of large molecules is largely required in drug development in order to validate whether large molecule drugs can successfully elicit an immune response (e.g. activate immune cells) from a subject. If so, the drug candidate is more likely to move forward in the design process and potentially make it to human testing in clinical trials.
