A novel fluorine-containing Lewis X derivative represented by the following formula (I):
wherein R represents hydrogen, a hydroxyl-protective group, -PO(OH)2, -SO3H or sialylate;
R1 represents hydrogen, hydroxyl, aliphatic acyloxy, aromatic acyloxy, lower alkylthio, optionally substituted phenylthio, lower alkoxy, branched long chain alkoxy, optionally substituted phenylmethoxy or sphingosinyl, R10 represents hydrogen or -O-C-(=NH)CCl3; provided that when R10 is -O-C-(=NH)CCl3, R9 is hydrogen;
R2 and R3 are the same or different and independently represent hydrogen, aliphatic acyl, aromatic acyl or optionally substituted phenylmethyl; and
R4 represents hydroxyl, aliphatic acyloxy, aromatic acyloxy, aliphatic acylamino or aromatic acylamino.
