A compound of the general formula (I): (wherein the symbols are as defined in the description), or a non-toxic salt thereof. This compound engages in LPA receptor bonding and antagonism and hence is useful in the prevention and/or treatment of urinary system disease (symptom with prostatic hypertrophy or neurogenic bladder dysfunction disease, symptom to be caused by spinal cord neoplasm, nucleous hernia, spinal canal stenosis or diabetes, occlusion disease of lower urinary tract, inflammatory disease of lower urinary tract, polyuria), carcinoma-associated disease (solid tumor, solid tumor metastasis, angiofibroma, myeloma, multiple myeloma, Kaposi's sarcoma, leucemia and carcinomatous infiltration transition), proliferative disease (disorder with aberrant angiogenesis, artery obstruction and pulmonary fibrosis), inflammation/immune system disease (psoriasis, nephropathy, hepatitis and pneumonitis symptom), disease caused by secretory dysfunction (Sjogren syndrome), brain-related disease (brain infarction, cerebral apoplexy and brain or peripheral neuropathy) or chronic disease (chronic asthma, glomerulonephritis, obesity, prostate hyperplasia, diseases caused by arteriosclerosis process, rheumatism or atopic dermatitis).

LPA receptor antagonist

Provided are: a compound represented by formula (I): (wherein ring A and ring D each represent a cyclic group which may have a substituent(s); E and G each represent a bond or a spacer having 1 to 8 atoms in its main chain; L represents a hydrogen atom or a substituent; X represents amino which may have a substituent(s), or a heterocyclic group which contains at least one nitrogen atom and which may have a substituent(s); n represents 0 to 3, in which when n is 2 or more, a plurality of ring A's may be the same or different from one another); a salt thereof; an N-oxide form thereof; a solvate thereof, a prodrug thereof; and a medicament which includes those. The compound represented by formula (I) is capable of binding S1P receptors (in particular, EDG-1 and/or EDG-6), and useful for preventing and/or treating rejection in transplantation, autoimmune diseases, allergic diseases, etc.

The present invention relates to a compound represented by formula (I): (wherein the symbols in formula were described in the description), a salt thereof, a solvate thereof or a prodrug thereof. Since the compound of the present invention binds to and is antagonistic to an LPA receptor (particularly, EDG-2), it is useful for prevention and/or treatment of urinary system disease (prostatic hypertrophy or neurogenic bladder dysfunction disease, spinal cord neoplasm, nucleous hernia, spinal canal stenosis, diseases caused by diabetes, occlusion disease of lower urinary tract, inflammatory disease of lower urinary tract, and polyuria), carcinoma-associated disease, proliferative disease, inflammation system disease, immune system disease, disease by secretory dysfunction, brain-related disease and/or chronic disease.

Compounds having lysophosphatidic acid receptor antagonism and uses thereof

A compound having an ability to bind to an S1P receptor (particularly EDG-6, preferably EDG-1 and EDG-6), for example, the compound represented by formula (I) of the present invention, a salt thereof, a solvate thereof or a prodrug thereof is useful for prevention and/or treatment of rejection of transplantation, graft-versus-host disease, autoimmune disease, allergic disease and the like. wherein ring A is a cyclic group; ring B is a cyclic group which may have substituent(s); X is a spacer having 1 to 8 atoms in its main chain, etc.; Y is a spacer having 1 to 10 atoms in its main chain, etc.; n is 0 or 1, wherein when n is 0, m is 1 and Ris a hydrogen atom or a substituent, and wherein when n is 1, m is 0 or an integer of 1 to 7 and Ris a substituent, and wherein m is 2 or more, Rs are the same or different.

Azetidine ring compounds and drugs comprising the same

A remedy and/or a preventive for a chronic disease which contains an EDG-2 antagonist. Because of binding to a subtype EDG-2 of LPA receptor, an EDG-2 antagonist is useful in treating and/or preventing chronic diseases (for example, diseases caused by the progress of chronic asthma, glomerular nephritis, obesity, arteriosclerosis, rheumatoid and atopic diseases) induced and made chronic by tissue cells whose proliferation is accelerated by LPA mediated by EDG-2.

Remedy for chronic disease

The present invention relates to a pharmaceutical composition for treatment and/or prevention for urinary diseases comprising a lysophosphatidic acid (LPA) receptor regulator. As LPA receptor regulators act on urethra and prostate, compounds acting on this receptor are useful in treating urinary diseases (urinary incontinence, dysuria, etc.). For example, an LPA receptor agonist useful for treatment of urinary incontinence, while an LPA receptor antagonist is useful for treatment of dysuria, ischuria, pollakiuria, nocturia, urodynia and benign prostatic hyperplasia.
