Rg. Wilde et al., ACYL-COA-CHOLESTEROL ACYLTRANSFERASE (ACAT) INHIBITORS - HETEROCYCLICBIOISOSTERES FOR THE UREA GROUP IN DUP-128, Bioorganic & medicinal chemistry letters, 5(2), 1995, pp. 177-180
A series of compounds bearing two heterocyclic substituents were evalu
ated for inhibition of the ACAT enzyme. One heterocyclic group was cho
sen to mimic the urea group in our clinical candidate, DuP 128. Of the
several groups examined, aminobenzoxazoles proved to be the most pote
nt in terms of inhibition of ACAT in J774 macrophage cells.
