Patent ID: 6894034

Claim:
A method for treating a disease caused by excessive sebum production in a mammal, wherein said disease is acne vulgaris, said method comprising: administering to said mammal presenting said disease a therapeutically effective amount of a sebum production inhibitor containing as an active ingredient a compound of general formula (1) below having a glucuronic acid derivative and a glucosamine derivative in the structure or a pharmacologically acceptable salt thereof, Formula (1) where R 1 denotes a protective group or any of formulae (2) to (5) below where R 10 denotes a hydrogen atom, a protective group or any of formulae (6) to (8) below, and R 11 denotes a hydrogen atom or a protective group, provided that when R 10 and R 11 are a hydrogen atom or a protective group, R1 may be attached at the trans- or cis-position with respect to COOR 4 , —OR 10 Formula (2) —NHR 11 , Formula (3) —CH 2 R 11 Formula (4) —SR 11 , Formula (5) or when R 10 is any of formulae (6) to (8), R 12 to R 28 except R 13 , R 17 and R 26 in formulae (6) to (8) are the same or different and denote a hydrogen atom or a protective group, and R 13 , R 17 and R 26 denote an azido group or formula (9) below —NR 29 R 30 formula (9) where R 29 and R 30 are the same or different and denote a hydrogen atom or a protective group, R 2 to R 4 are the same or different and denote a hydrogen atom or a protective group, R 9 denotes formula (11) below Formula (11) where R 35 to R 37 are the same or different and denote a hydrogen atom or a protective group, and n denotes an integer of 0 to 25, provided that when n is 0, R 1 is a group of formula (2) and R 10 is a group of formula (8), with the proviso that in formulae (1), (6) to (8), and (11), the protective groups are the same or different and denote an optionally substituted straight or branched alkyl having 1 to 8 carbon atoms, an optionally substituted straight or branched alkenyl having 2 to 8 carbon atoms, an optionally substituted acyl having 1 to 8 carbon atoms, an optionally substituted aromatic acyl, or an optionally substituted aromatic alkyl, or any two protective groups of R 2 to R 30 and R 35 to R 37 except R 13 , R 17 and R 26 may be combined to form an optionally substituted alkylidene having 3 to 8 carbon atoms, an optionally substituted cyclic alkylidene having 3 to 8 carbon atoms, optionally substituted benzylidene or optionally substituted phthaloyl, and when n is 2 or more, R 2 to R 8 may be the same or different in each recurring unit, and a pharmaceutically acceptable carrier.
