Models and Methods to Evaluate Transport of Drug Delivery Systems Across Cellular Barriers
Published on: October 17, 2013
Future directions for drug transporter modelling.
Computational models like QSAR and pharmacophore screening accelerate drug discovery by predicting transporter interactions, reducing the need for extensive lab studies. This approach aids in identifying drug candidates and anticipating drug-drug interactions.
Area of Science:
- Computational chemistry
- Drug discovery
- Pharmacology
Background:
- Since the late 1980s, computational methods have increasingly been used to study drug-transporter interactions, beginning with P-glycoprotein (P-gp).
- Identifying molecules interacting with transporters like P-gp is crucial for drug discovery but typically requires time-consuming in vitro and in vivo experiments.
Purpose of the Study:
- To highlight the utility of computational quantitative structure-activity relationship (QSAR) and pharmacophore models in predicting drug-transporter interactions.
- To demonstrate how these computational approaches can expedite the identification of novel drug substrates and inhibitors for transporters.
Main Methods:
- Application of quantitative structure-activity relationship (QSAR) and pharmacophore modeling.
- Rapid screening of molecular databases to identify potential transporter substrates or inhibitors.
- Verification of computational predictions through in vitro studies.
Main Results:
- Computational models enable rapid screening of large molecule databases, identifying potential binders for transporters.
- The use of these models has led to the discovery of new substrates and inhibitors for various transporters.
- Accurate predictions of transporter binding by computational and pharmacophore models can anticipate drug-drug interactions.
Conclusions:
- Computational QSAR and pharmacophore models offer an efficient alternative to traditional methods for assessing drug-transporter interactions.
- These models can accelerate drug discovery by prioritizing molecules for experimental validation and predicting potential drug-drug interactions.
- Future integration of these computational approaches into pharmacokinetic-pharmacodynamic models may enhance predictions of in vivo drug effects.
