  1. Interpretation note: as calculated by SwissADME36, all the compounds are predicted to have moderate to good solubility with high gastrointestinal (GI) absorption. The Lipophilicity is > 1 and < 5, indicating good oral absorption. Bioavailability of 0.55 indicates these drugs to be good candidates for further preclinical evaluation. None of the drug molecules are substrate for P-glycoprotein induction hence, are going to be bioavailable and have good bio distribution. As only 3 out of 5 CYP450 family of enzymes are inhibited suggesting that drugs may have high intracellular retention, but can be metabolized by the residual 2 CYP450 enzymes and can possibly be cleared by the renal system. They are anticipated to have low drug-drug interaction and low toxicity. None of the compounds are predicted to cross BBB—blood brain barrier.
