What is admetSAR ?

admetSAR provides the latest and most comprehensive manually curated data for diverse chemicals associated with known Absorption, Distribution, Metabolism, Excretion and Toxicity profiles. admetSAR created a user-friendly interface to search for ADMET properties profiling by name, CASRN and similarity search. In addition, admetSAR can predict about 50 ADMET endpoints by our recently development chemoinformatics-based toolbox, entitled ADMET-Simulator which integrates high quality and predictive QSAR models. admetSAR will be helpful for in silico screening ADMET profiles of drug candidates and environmental chemicals.
