Drug discovery

Definition

Drug discovery is the process of identifying and developing new pharmaceutical compounds that can be used to treat diseases or medical conditions. This involves a series of steps, including target identification, lead compound discovery, optimization, and preclinical testing, which require collaboration across various scientific disciplines and technologies to enhance efficacy and safety.

5 Must Know Facts For Your Next Test

1. Drug discovery typically begins with the identification of biological targets, such as proteins or genes associated with a disease.
2. The process often integrates various advanced technologies like genomics, proteomics, and bioinformatics to streamline the identification of potential drug candidates.
3. Lead compounds are then optimized for their pharmacokinetic properties to ensure they are safe and effective for human use.
4. Preclinical testing in animal models is crucial to evaluate the safety and biological activity of drug candidates before moving to human trials.
5. Collaboration between academic institutions, biotechnology companies, and pharmaceutical firms is essential for successful drug discovery efforts.

Review Questions
