A novel series of tetrazole-substituted ureas 2 were prepared from wea
kly nucleophilic amines using a new coupling method. The ureas were fo
und to potently inhibit liver ACAT in vitro and lower total serum chol
esterol in vivo. A comparison of urea 2b and the anti-atherosclerotic
CI-976 in a long-term model of atherosclerosis indicates the importanc
e of inhibiting arterial ACAT for reducing lesion size. Copyright (C)
