Patent ID: 7109340

Claim:
A compound of formula (I), including its tautomers: wherein: L is a bond; X is chosen from a bond, CH 2 , CO, SO 2 , CONH and COO; R1 is OH or H, or is chosen from alkyl, cycloalkyl, heterocycle, aryl, heteroaryl, chosen from benzimidazolyl, indolyl or pyrrolyl, all of which is optionally substituted, and, when X is a bond, then R1 may also be halogen; R2 is H or is chosen from alkyl, alkylene, cycloalkyl, heterocycle, aryl, heteroaryl, chosen from pyridyl, furanyl or thienyl, all of which is optionally substituted; and in that the optional substituents are chosen independently from R3, O—R3, halogen, NO 2 , SO 2 —R3, CO—R3, SO 2 NH—R3, CONH—R3, N—(R3) 2 , NHCO—R3, NHSO 2 —R3, NHCONH—R3, NHSO 2 NH—R3, OCO—R3, COO—R3, OSO 2 —R3, SO 2 O—R3, OCONH—R3 and OSO 2 NH—R3, wherein R3 is H or is chosen independently from alkyl, cycloalkyl, alkenyl, aryl, heteroaryl chosen from benzimidazolyl, indolyl, pyridyl, furanyl, thienyl or pyrrolyl, heterocycle, all of which is optionally substituted with halogen, aryl, heteroaryl chosen from benzimidazolyl, indolyl, pyridyl, furanyl, thienyl or pyrrolyl, R4, OR4 or N(R4) 2 , wherein each R4 is chosen independently from H, C 1 –C 4 alkyl and halogenated C 1 –C 4 alkyl, or a racemate, a stereoisomer, an enantiomer, or a mixture in any combination thereof, or a pharmaceutically acceptable salt thereof; with the proviso that: when R1 is OH and X is a bond or COO, then R2 is not hydrogen or methyl; when R1 is methyl, cyclopropyl or 4-fluorophenyl, and X is a bond, then R2 is not hydrogen.
