WebIntroduction. Renal clearance is most commonly a feature of polar, low LogD7.4 (<~1) compounds due to their low plasma protein binding, lack of passive permeability (and inability to facilitate re-absorption in the distal tubule), and the high expression in the kidney of a number of transporter proteins (e.g. OATs and OCTs).
