Patent ID: 7279480

Claim:
A compound of formula (I): wherein n is an integer from 0 to 6; R 1 is selected from C(O)—(CH 2 ) m —R, C(O)—NH—(CH 2 ) m —R, C(S)—NH—(CH 2 ) m —R, SO 2 —(CH 2 ) m —R, wherein m is an integer from 0 to 6, and when m is greater than 2 a double bond is optionally present; R is selected from hydrogen when m is other than 0, hydroxyl, thiol, cyano, linear or branched alkoxy containing from 1 to 6 carbon atoms, aryloxy, aralkoxy, cycloalkyl having from 3 to 6 carbon atoms, a saturated or unsaturated monocyclic or bicyclic heterocyclic group, wherein the ring of the heterocyclic group is optionally substituted with one to three substituents independently selected from OH, SH, NH 2 , NO 2 , cyano, carboxyl, carbamoyl, halogen, trifluoromethyl, linear or branched alkyl containing from 1 to 6 carbon atoms, linear or branched alkoxy containing from 1 to 6 carbon atoms, acyl containing from 2 to 6 carbon atoms, aryl, aralkyl, or a saturated or unsaturated monocyclic or bicyclic heterocycle, wherein said alkyl, aryl, aralkyl or heterocycle is each optionally substituted with one to three substituents independently selected from OH, SH, NH 2 , NO 2 , cyano, carboxyl, carbamoyl, halogen, or trifluoromethyl; aryl containing from 6 to 10 carbon atoms or aralkyl containing from 7 to 11 carbon atoms, wherein the ring of said aryl or aralkyl is each optionally substituted with one to three substituents independently selected from OH, SH, NH 2 , NO 2 , cyano, carboxyl, carbamoyl, halogen, trifluoromethyl, linear or branched alkyl containing from 1 to 6 carbon atoms, linear or branched alkoxy containing from 1 to 6 carbon atoms, acyl containing from 2 to 6 carbon atoms or a saturated or unsaturated monocyclic or bicyclic heterocycle, wherein said alkyl or heterocycle is each optionally substituted with one to three substituents independently selected from OH, SH, NH 2 , NO 2 , cyano, carboxyl, carbamoyl, halogen or trifluoromethyl; or NR 4 R 5 wherein R 4 is hydrogen or a linear or branched alkyl group having from 1 to 6 carbon atoms, and R 5 is hydrogen, a linear or branched alkyl radical having from 1 to 6 carbon atoms, or an aryl group; R 2 is hydrogen or is as defined for R 1 , wherein R 2 and R 1 are identical or different; N═R 3 is NH—R 3 or N═R 3 , when N═R 3 is NH—R 3 , R 3 is as defined for R 1 wherein R 3 and R 1 are identical or different, and when N═R 3 is N═R 3 , R 3 is as defined for R wherein R 3 and R are identical or different; or an enantiomer, a racemate, a diastereoisomer, or a mixture in any combination thereof, or a pharmaceutically acceptable salt thereof.
