The Role of Bioanalysis in Drug Discovery and Development

Bioanalysis plays a key role in drug discovery and development, providing important data at every stage from preliminary research and drug discovery to preclinical, nonclinical, clinical, and post-marketing studies. During the drug development process, bioanalysis helps researchers understand the behavior of drugs in the body, including absorption, distribution, metabolism, and excretion. Accurately measuring drug concentrations in physiological fluids ensures that the drug reaches its intended molecular target, thereby optimizing therapeutic efficacy and safety. Bioanalysis also helps with dose selection and dosing regimen design. Overall, bioanalysis is essential for the careful evaluation and successful development of new therapies and drugs. Protheragen is a professional drug development company, and we have a team dedicated to Obesity-related Targets, drug and therapy research, and developing new Anti-Obesity Therapies to combat the widespread problem of obesity.

Precision at Every Stage: Unlocking Bioanalysis for Obesity-related Small Molecule Drug

Protheragen provides clients with unparalleled bioanalytical services for obesity-related small-molecule drugs. Our services include method development and confirmation such as liquid chromatography-tandem mass spectrometry (LC-MS/MS). We also provide quantitative drug detection in biological samples such as plasma, tissue, urine, and feces, supporting obesity-related small molecule drug screening and development as well as preclinical research. Our service details are as follows:

• Bioanalytical Method Development and Validation

  The development and validation of bioanalytical methods for small molecule drugs is a critical step in the drug development process, ensuring the reliability and accuracy of data used to evaluate drug safety and efficacy. First, we identify or develop a suitable analytical method, focusing on parameters such as sensitivity, specificity, linearity, precision, and accuracy to reliably detect and quantify small molecules in biological matrices such as blood, plasma, or urine. Once the method is established, we will conduct rigorous validation following regulatory guidelines. This usually involves evaluating the performance of the method through various tests, including accuracy, precision, recovery, matrix effects, stability, and robustness. The methods we develop include but are not limited to high-performance liquid chromatography (HPLC), LC-MS/MS, hydrophilic interaction chromatography (HILIC), size exclusion chromatography (SEC), ion exchange chromatography (IEC), etc.

• Sample Collection and Pretreatment

  We perform bioanalysis of small molecule drugs in various forms such as serum, plasma, tissue, urine, feces, etc. The drugs we analyze include but are not limited to traditional small molecule drugs, amino acids, peptides, oligonucleotides, lipid nanoparticle embedded analytes (LNP), lipids, steroids, peptides and small proteins, acylated peptides, and toxins.

• Stability Test

  Stability testing of small molecule drugs evaluates the chemical, physical, and microbiological stability of drugs over time under various environmental conditions such as temperature, humidity, and light. This testing helps determine the shelf life, proper storage conditions, and formulation of drugs. We subject drugs and products to different stress conditions to observe degradation pathways and identify potential breakdown products.

• Protein Binding Studies

  Protein binding studies of small molecule drugs are designed to assess the amount of drug bound to plasma proteins, which greatly affects the drug's pharmacokinetics and pharmacodynamics. These tests typically include equilibrium dialysis, ultrafiltration, and ultracentrifugation to determine the free (unbound) fraction versus the bound fraction of the drug. MS techniques are often used to accurately quantify the concentration of bound and unbound drugs, which helps understand the drug's distribution, efficacy, and potential for drug-drug interactions.

• Biomarker Analysis

  Biomarker analysis is used to identify, quantify, and validate biomarkers that indicate drug efficacy, toxicity, or biological responses. We measure biomarker levels in biological samples such as blood, plasma, or tissue using techniques such as enzyme-linked immunosorbent assay (ELISA), MS, and western blot. We also evaluate pharmacodynamic biomarkers to understand drug mechanisms and their biological effects. In addition, we run genomic and proteomic analyses to evaluate gene expression and protein modifications associated with drug action.

• Metabolite Identification

  We perform in vitro metabolism studies using liver microsomes, hepatocytes, or other relevant biological systems to determine initial metabolic conversions. LC-MS and LC-MS/MS are used to detect and characterize the chemical structure of metabolites. Radiolabeling is used to track drug distribution and metabolite formation. In vivo studies are performed in animal models to confirm the presence and concentration of metabolites.

• Toxicology Assay

  We evaluate the safety of candidate compounds through a battery of tests, which typically include acute toxicity studies to determine immediate harmful effects following a single dose or exposure, and chronic toxicity studies to assess the effects of long-term repeated dosing. We also perform genotoxicity testing to assess the potential of a drug to damage genetic material, which may include tests such as in vitro chromosome aberration assays and in vivo micronucleus assays. In addition, organ toxicity studies are used to determine specific toxic effects on specific organs such as the liver, kidneys, and heart.
