P-glycoprotein inhibitor I ADMET Feature Prediction


  • MDR1 inhibitor
  • p-gp inhibitor I
  • pgp 1 inhibitor
  • pgp inhibitor 1
  • pgp inhibitor I

This describes a substance that inhibits P-glycoprotein I. P-glycoprotein (P-gp/MDR1), is one of the most clinically important transporters in the human body, and is encoded by the ABCB1/MDR1 gene 2. The inhibition of the p-glycoprotein I transporter may have various medical effects and serious effects on other drugs that are given.

DrugBank automatically retrieves information from the admetSAR database, using a table format to display various predicted properties of a drug under the "Predicted ADMET features" section of a drug entry 1. This database predicts the absorption, distribution, metabolism, excretion, and toxicity of drugs (ADMET). This database also identifies drugs as predicted p-glycoprotein I "inhibitors" or "non-inhibitors". In the example below, obtained from the Acetaminophen drug entry, this drug is classified as a p-glycoprotein I "non-inhibitor". Other drugs may be classified as "inhibitors".
