Computational tools for ADMET


ADMET stands for Absorption, Distribution, Metabolism, Excretion and Toxicity. The prediction of the ADMET properties plays an important role in the drug design process because these properties account for the failure of about 60% of all drugs in the clinical phases. Where traditionally ADME tools were applied at the end of the drug development pipeline, nowadays ADME is applied at an early phase of the drug development process, in order to remove molecules with poor ADME properties from the drug development pipeline and leads to significant savings in research and development costs.

ADMET allow to eliminate compounds with unfavorable ADMET characteristics early on to avoid expensive reformulation later, and to evaluate proposed structural refinements that are designed to improve ADMET properties, prior to resource expenditure on synthesis.


Web Interface on Libraries:

There are number of libraries (e.g. R, Bioconductor, Biojava) which provides number of tools. Though these libraries are powerful but one need expertise in computer. Development of web interfaces over these libraries are going on in order to provide service to users who have little or no knowledge of computer.
