stability of the conjugates was evaluated in Caco-2 and liver homogenate. Both conjugates were potent inhibitors of ASBT. For the niacin prodrug, substrate kinetic parameter K(t) was 8.22microM and normJ(max) was 0.0917. In 4h, 69.4% and 26.9% of niacin was released from 1microM and 5microM of the conjugate in Caco-2 homogenate, respectively. For the ketoprofen prodrug, K(t) was 50.8microM and normJ(max)
