Patent ID: 7737287

Claim:
A compound of formula I Being a modified monosaccharide, wherein, n is 0 or 1; R1 is selected from the group consisting of hydrogen or —N(Z)Y wherein; Y is selected from the following, where G denotes the point of connection to the nitrogen atom in N(Z)Y; Z is selected from hydrogen or W; Q is selected from hydrogen or W; the groups W are independently selected from the group consisting of: a) a substituted or unsubstituted alkyl moiety of 1 to 20 atoms; b) a substituted or unsubstituted alkenyl, or alkynyl moiety of 2 to 20 atoms; c) a substituted or unsubstituted heteroalkyl moiety of 2 to 20 atoms in which the hetero atoms are selected from the group consisting of N, O and S; d) a substituted or unsubstituted monocyclic or bicyclic aryl moiety of 6 to 12 carbon atoms; e) a substituted or unsubstituted monocyclic or bicyclic heteroaryl moiety of 5 to 20 atoms, containing 1 to 4 hetero atoms selected from the group N, O and S; f) an arylalkyl moiety of 6 to 20 atoms comprising at least 1 substituted or unsubstituted monocyclic or bicyclic aryl moiety and a substituted or unsubstituted alkyl moiety; g) an heteroarylalkyl moiety of 5 to 20 atoms comprising a substituted or unsubstituted monocyclic or bicyclic heteroaryl moiety containing 1 to 4 hetero atoms selected from the group N, O and S, and a substituted or unsubstituted alkyl moiety; the groups R2, R3, R4 and R5 are independently selected from —OH, —OW and —N(Z)Y wherein at least one of the groups R2, R3, and R4 is —N(Z)Y, and at least one of the groups R2, R3, R4 and R5 is —OW and at least one of the groups R2, R3, R4 and R5 is —OH, Z and Y optionally combine with N to form a ring, such that where more than one of the groups R2, R3, R4 and R5 is OW, each instance of OW is different.
