Abstract:
1. A compound of formula I wherein, n is 0 or 1; R1 is XR wherein, X is selected from O; S; S═O and SO R is a moiety selected from the group consisting of: C1 to C9 alkyl, C2 to C15 alkenyl, C2 to C15 alkynyl, C1 to C15 heteroalkyl, C6 to C15 aryl, C6 to C15 heteroaryl, C6 to C15 arylalkyl or C6 to C15 heteroarylalkyl; which moiety R is optionally substituted, cyclic or acyclic, branched and/or linear, R2 is N(Y)Z, R3 is OR, where in each occurrence of the moiety OR, R forms an ether bond, R4 is selected from the group consisting of OH, OR and N(Y)Z, R5 is selected from the group consisting of OH and OR, such that when n is 1, one, but not both, of R4 and R5 is OH, where more than one of R3, R4, and R5 are OR, the OR groups at R3 and R4 or R5 are different, Z is selected from hydrogen or R and Y is selected from the following, where G denotes the point of connection to the nitrogen atom in N(Y)Z, and the groups Q and W are independently selected from hydrogen or R as is defined above, and Q and W may combine to form a cycle, the groups Z and Y may combine to form a cycle, the groups R1 to R5 may not combine together to form a cycle, with the proviso that where two groups in the compound of formula I are N(Y)Z, these groups are different, with the further proviso that N(Y)Z may not be trifluoroacetamido, acetamido, with the further proviso that the group R may not be or contain another saccharide moiety; and wherein the optional substituents are selected from the group consisting of OH, NO, NO
