Abstract
The present invention provides N-substituted aryl-N'-heterocyclic substituted ureas and thioureas of the formula ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are hydrogen, fluorine, chlorine, bromine, alkyl, alkoxy, substituted or unsubstituted benzoyl, substituted or unsubstituted phenyl, amino, substituted amino, or a monocyclic heterocyclic, or a carboxy group; and Het is a substituted monocyclic heterocyclic group containing two hetero atoms selected from nitrogen, oxygen or sulfur; which are useful in treating hypercholesterolemia and atherosclerosis.
Claims5
A compound of the formula
- wherein
- X is oxygen or sulfur;
- wherein each of R.sub.1, R.sub.2, and R.sub.3 is the same or different and is selected from
- hydrogen,
- fluorine,
- chlorine,
- bromine,
- a straight or branched alkyl group having from one to six carbon atoms,
- a straight or branched alkoxy group having from one to six carbon atoms,
- benzoyl which is unsubstituted or is substituted on the aromatic ring with from one to three substituents selected from fluorine, chlorine, bromine, iodine, a straight or branched alkyl group having from one to six carbon atoms, or a straight or branched alkoxy group having from one to six carbon atoms,
- benzyl which is unsubstituted or is substituted on the aromatic ring with from one to three substituents selected from fluorine, chlorine, bromine, iodine, a straight or branched alkyl group having from one to six carbon atoms, or a straight or branched alkoxy group having from one to six carbon atoms,
- phenyl which is unsubstituted or is substituted with from one to three substituents selected from fluorine, chlorine, bromine, iodine, a straight or branched alkyl group having from one to six carbon atoms, or a straight or branched alkoxy group having form one to six carbon atoms,
- NR.sub.4 R.sub.5 wherein each of R.sub.4 and R.sub.5 is the same or different and is hydrogen, a straight or branched alkyl group having from one to four carbon atoms or --NR.sub.4 R.sub.5 taken together from a monocyclic heterocyclic group selected from pyrrolidino, piperidino, piperazine, or piperazine substituted on the 4-position with a straight or branched alkyl group having form one to four carbon atoms;
- --COR.sub.6 wherein R.sub.6 is hydroxy, a straight or branched alkoxy group having from one to six carbon atoms, benzyloxy which is unsubstituted or is substituted on the aromatic ring with from one to three substituents selected from fluorine, chlorine, bromine, iodine, a straight or branched alkyl group having from one to six carbon atoms, or a straight or branched alkoxy group having from one to six carbon atoms, or R.sub.6 is --NR.sub.4 R.sub.5 wherein R.sub.4 and R.sub.5 have the meanings defined above;
- wherein Het is selected from ##STR9## wherein R.sub.7 is straight or branched alkyl having from 9 to 14 carbon atoms;
- and pharmaceutically acceptable salts and isomers thereof.
