Patent ID: 7435820

Claim:
A compound of formula (I), including its tautomers: wherein: L is chosen from CH 2 , CO, SO 2 , COO, NHCO, NHSO 2 , and NHCH 2 ; 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, 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, 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, heterocycle, all of which is optionally substituted with halogen, aryl, heteroaryl, 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.
