摘要:
Therapeutic or preventive agents for system lupus erythematosus, glomerulonephritis, lupus nephritis, idiopathic thrombocytopenic purpura or autoimmune anemia, which can be substituted for conventional steroid preparations or immunosuppressive agents. The active ingredients of the therapeutic or preventive agents are agonists for retinoic acid receptors, particularly retinoic receptor, subtype α (i.e., RAR α), and examples of the agonists include (1) carboxylic acid derivatives bearing fused rings as represented by general formula (I) wherein rings L and M are fused with each other, and are each independently an optionally substituted aromatic hydrocarbon ring or an optimally substituted heterocycle; rings A and B are each independently an optionally substituted aromatic hydrocarbon ring or a heterocycle; and D is optionally protected carboxyl, and (2) 4-{[(3,5-bistrimethylsilylphenyl)carbonyl]amino}benzoic acid and 4{2-[5-(3-methoxymethyl-5,6,7,8-tetrahydro-5,5,8,8,-tetramethylnaphthalen-2-yl)-pyrrolyl]}benzoic acid.
摘要:
Fused-ring carboxylic acid derivatives represented by general formula (A) and pharmacologically acceptable salts thereof, which can provide medicines excellent in retinoic acid receptor agonist activities, wherein the symbol represents a single or double bond; and each of X, Y, Z, P, Q, U, V and W represents -O-, -S- or a group represented by formula (a), wherein R k (k:1-8) represents hydrogen, halogeno, optionally substituted lower alkyl, etc., and either R 7 or R 8 represents a group represented by formula (b), wherein rings A and B represent each independently an optionally substituted aromatic hydrocarbon or unsaturated heterocyclic ring; and D represents an optionally protected carboxyl group.
