Bioinformatics Analysis for Preclinical Research


Preclinical research refers to the chemical synthesis or natural product purification research and drug analysis research conducted before the drug enters the clinical research, including pharmacodynamics, pharmacokinetics and toxicology research, as well as pharmaceutics research and drug evaluation of potential therapeutic interventions in cells and animals. Then, candidates for clinical trials are selected based on the effectiveness and safety of the drug in the disease model. Before the start of clinical trials, all drugs need data from various toxicological preclinical trials to study the safety of the drug in humans.

Application of Bioinformatics in the Preclinical Research

With the development of genomes, genomics methods are often used in the target identification/validation stage of drug development, but genomics methods are often ignored in the preclinical stage. Before the drug enters the clinic, it is necessary to conduct efficacy and safety tests in vivo and in vitro. This process is time-consuming and expensive. Moreover, the results of efficacy and safety evaluation data obtained are not representative of all individuals. Through genomics methods, microarray technology or next-generation sequencing technology, combined with bioinformatics methods, genomic changes related to toxicology or non-targeting can be effectively identified. It provides a data basis for subsequent wet experiments and saves time, manpower and material costs for pre-clinical research to a large extent.

How We Can Help Your Preclinical Research

By combining our expertise in bioinformatics analysis with our extensive knowledge in the field of preclinical research, our bioinformatics service can help:

1. Genotyping analysis: by performing genotyping analysis on microarray data or sequencing data of various omics, mining genetic polymorphisms related to individual differences in drug response, including:

  • Through the analysis of gene polymorphisms related to drug-metabolizing enzymes, predict the causes of individual differences in drug reactions.
  • Analyze the genetic polymorphisms of drug transporters to predict the causes that affect drug transport, absorption, distribution, and elimination from the body.
  • The analysis of gene polymorphisms of drug targets can predict the causes of the effects of different drugs (for example, different doses) in individuals.

2. Data mining: Combined with relevant drug databases, it can predict the efficacy of drugs, predict the dose of drugs, avoid ADR of drugs and find new targets for drugs.

In addition, if you have other analysis needs related to preclinical research, we will provide you with analysis services. We will use cutting-edge analysis technology to conduct personalized data analysis according to the customer's project analysis needs.
