Patent ID: 8202896

Claim:
A compound having the formula: wherein: R 1 represents a radical selected from the group consisting of —NR 5 R 6 , —SO 2 NR 7 R 8 , hydroxyalkyl, hydroxyalkoxy, polyhydroxyalkyl, alkoxyalkoxy, polyfluoroalkyl, dialkylaminoalkyl, R 9 , —OR 9 , n being an integer from 1 to 4; R 2 and R 3 are each independently selected from the group consisting of straight or branched chain alkyl and hydrogen; R 4 is a radical selected from the group consisting of a substituted or unsubstituted phenyl radical, an unsubstituted or substituted heterocyclic radical, and —NR 12 R 13 ; R 5 and R 7 are independently selected from the group consisting of alkoxyalkyl, hydroxyalkyl, polyhydroxyalkyl, aralkyl, R 9 , —(C═O)R 14 and —(C═O)R 9 ; R 6 , R 8 , R 12 , and R 13 are independently selected from the group consisting of hydrogen, alkyl, alkoxyalkyl, polyfluoroalkyl, hydroxyalkyl, polyhydroxyalkyl, aralkyl, R 9 , —(C═O)R 15 and —(C═O)R 9 ; or R 5 and R 6 taken together with the nitrogen to which they are attached form a substituted or unsubstituted heterocyclic radical, said heterocyclic radical optionally containing one to two additional heteroatoms independently selected from the group consisting nitrogen, oxygen, and sulfur; or R 7 and R 8 taken together with the nitrogen to which they are attached form a substituted or unsubstituted heterocyclic radical, said heterocyclic radical optionally containing one to two additional heteroatoms independently selected from the group consisting nitrogen, oxygen, and sulfur; said phenyl and heterocyclic radical substituents being at least one selected from the group consisting of alkyl, amino, hydroxy, carbonyl, monoalkylamino, dialkylamino, halogen, and alkoxy; R 9 is a radical of the formula —W—O(C═O)—CH 3 , W being a straight- or branched-chain alkylene group of 1 to 6 carbon atoms; R 10 and R 11 are radicals independently selected from the group consisting of alkyl, halo, haloalkyl, and polyfluoroalkyl; R 14 is a hydroxyalkyl, alkoxyalkyl or cycloalkyl group; R 15 is an alkyl, hydroxyalkyl, alkoxyalkyl or cycloalkyl group, and pharmaceutically acceptable salts of said compound.
