- Optimization of drug potency, specificity, and pharmacokinetic properties.
4. Chemical Genomics and Proteomics:
- Application of chemical probes to screen large libraries of genes or proteins.
- Identification of novel therapeutic targets and molecular networks involved in diseases.
5. Precision Medicine:
- Personalized treatments based on genomic and proteomic profiles of individual patients.
- Use of chemical probes to tailor therapies to specific disease subtypes.
6. Chemical Resistance and Overcoming Barriers:
