Inositol glycan derivatives of formula (I), their salts and stereoisomeric forms, are new: A-Z-R (I) A = HP(=O)(OH), HP(=S)(OH), HOP(=S)(OH), HSP(=S)(OH), (1-4C alkyl)P(=O)(OH), (1-4C alkyl)P(=S)(OH), SO2ORl, S(=O)OR1, NH2CO, NR1R2, R1R2NCONH, R1OSO2NH, (1-4C alkyl)SO2, (1-4C alkyl)S(=O) or R1S; R1, R2 = H or 1-4C alkyl; Z = 2-6 sugar residues (optionally substituted by up to 6 Me, sugar residue, di-sugar residue, SO2OH, CONR1R2, CO(1-4C alkyl), P(=O)(H)OH, P(=O)(OH)2, P(=S)(H)OH, P(=S)(OH)2, P(=S)(SH)(OH), P(=O)(OH)OCH2CH2NR1R2), or the glycosidic bridge between the 2-6 sugar residues may be 1-6 fold replaced by CH2 or S; R = inositol, inositol phosphate, inositol thiophosphate, inositol cyclo-phosphate, inositol cyclo-thiophosphate (optionally substituted by 1-2 phosphate or thiophosphate, or single substitution by cyclo-phosphate or cyclo-thiophosphate), or inositol (where two neighbouring OH groups are replaced by CH2SO2NH). |
