BAY o 2752 (N,N-(1,11-undecandiyl)bis(2,3-dihydro-2-methyl-1H-indole-1-carboxamide)) has been demonstrated to inhibit intestinal cholesterol absorption in rats. Studies were carried out on male Wistar rats to determine if this drug alters intestinal bile acid absorption or cholesterol esterification by acyl CoA: cholesterol acyltransferase (ACAT) or cholesterol ester hydrolase (CEH). BAY o 2752 did not affect intestinal absorption of taurocholic acid (TC) from ileal segments perfused in vivo with a tragacanth suspension in phosphate buffer containing NaCl, TC, and 24-{sup 14}C-TC as determined by the excretory rate of radioactivity in bile. BAY o 2752 also did not affect the uptake of TC into ileal everted sacs incubated in stirred, gassed Krebs-Ringer bicarbonate buffer with 1 mM TC, 24-{sup 14}C-TC and {sup 3}H-inulin. BAY o 2752 also did not bind TC; TG, in a filtrate of the above solutions remained at 92-98% of control.
