A glycolipid derivative represented by the formula (I): (I) wherein R1 represents an aldopyranaose residue, R2 represents a hydrogen atom or a hydroxyl group, A represents -CH2-,-CH(OH)-CH2- or -CH=CHCH2-, Z represents -O-or -CH2-, and y represents an integer of 26 to 35 when Z represents -O- and x represents an integer of 4 to 16, y represents an integer of 0 to 35 when Z represents -O- and x represents an integer of 17 to 25, y represents an integer of 26 to 35 when Z represents -CH2- and x represents an integer of 4 to 15 and y represents an integer of 0 to 35 when Z represents -CH2- and x represents an integer of 16 to 25; and a therapeutic agent for an autoimmune disease (e.g., autoimmune arthritis), an allergic disease (e.g., bronchial asthma) or a disease of which an NKT cell or the stimulation of an NKT cell is known to be involved in the aggravation of the condition comprising the glycolipid derivative. |
