“…• molecular weight > 500 for humans (> 250 for rat), as compounds of this size are more likely to be eliminated by the hepato-biliary pathway [190] • log D pH 7.4 > 0, as hydrophobic compounds pass through cell membranes such as the liver, where CL H is an effective means of removal from the body [191] • liver/plasma ratio > 1, as this implies hepatic uptake • literature or historical data indicating role of hepatic clearance for chemical class, for example, the thiazolidinediones, endothelin A receptor antagonists and statin drugs [49,[192][193][194][195][196][197] • evidence of hepatic toxicity in chemical class, for example, troglitazone [68,197,198], bosentan [199], glyburide [200], and tacrine [201] • predicted human biliary excretion > 50%…”
