Patent ID: 7358367

Claim:
A compound of formula (I), wherein R 1 individually represents hydrogen, hydroxyl or a group of the formula (II), wherein X individually represents C 1 -C 6 alkyl group, C 2 -C 6 alkenyl group; or X individually represents C 1 -C 6 alkyl group with at least one incorporated O, S or N atom or X individually represents (CH 2 ) n —Ar or X individually represents (CH 2 ) n -heterocycloalkyl, wherein (CH 2 ) n individually represents alkyl, wherein n is 1-10, with or without incorporated atom O, S or N, wherein Ar individually represents 5-10-membered monocyclic or bicyclic aromatic ring with 0-3 O, S or N atoms, unsubstituted or substituted with 1-3 groups, which are selected independently from halogen, OH, OMe, NO 2 , NH 2 , amino-C 1 -C 3 alkyl or amino-C 1 -C 3 dialkyl, CN, SO 2 NH 2 , C 1 -C 3 alkyl, and heterocycloalkyl represents unaromatic, partially or completely saturated 3-10-membered monocyclic or bicyclic ring system, or a 6-membered aromatic or heteroaromatic ring connected with a unaromatic ring with or without incorporated O, S or N atom, unsubstituted or substituted with 1-4 groups which are selected independently from halogen, OH, OMe, NO 2 , NH 2 , amino-C 1 -C 3 alkyl or amino-C 1 -C 3 dialkyl, CN, SO 2 NH 2 , C 1 -C 3 alkyl, —C(O)—, COOH or R 1 together with R 2 represents ketone, R 2 individually represents hydrogen or together with R 1 represents ketone or together with R 3 forms an ether bond, R 3 individually represents hydroxyl, a group of the formula —OX or together with R 2 forms an ether bond, R 4 individually represents hydrogen, C 1 -C 4 alkyl group or C 2 -C 4 alkenyl group, and R 5 individually represents hydrogen or hydroxyl protected group, or a pharmaceutically acceptable addition salt or hydrate thereof.
