Squaric acid derivatives of formula (1) are described:
1
wherein
R
1
is a group Ar
1
Ar
2
Alk- in which
Ar
1
is an optionally substituted aromatic or heteroaromatic group;
Ar
2
is an optionally substituted phenylene or nitrogen-containing six-membered heteroarylene group; and Alk is a chain
—CH
2
—CH(R)—, —CH═C(R)—,
2
in which R is a carboxylic acid (—CO
2
H) or a derivative or biostere thereof;
R
2
is a hydrogen atom or a C
1-6
alkyl group;
L
1
is a covalent bond or a linker atom or group;
n is zero or the integer 1;
Alk
1
is an optionally substituted aliphatic chain;
R
3
is a hydrogen atom or an optionally substituted heteroaliphatic, cycloaliphatic, heterocycloaliphatic, polycycloaliphatic, heteropolycycloaliphatic, aromatic or heteroaromatic group: and the salts, solvates, hydrates and N-oxides thereof.
The compounds are able to inhibit the binding of integrins to their ligands and are of use in the prophylaxis and treatment of immune or inflammatory disorders, or disorders involving the inappropriate growth or migration of cells.
描述了公式(1)的苯并二酸衍生物:其中R1是一种Ar1Ar2Alk-基团,其中Ar1是一个可选择取代的芳香或杂芳基团;Ar2是一个可选择取代的苯基或含氮的六元杂环芳基团;而Alk是一个链—CH2—CH(R)—,—CH═C(R)—,其中R是羧酸(—CO2H)或其衍生物或生物类似物;R2是氢原子或C1-6烷基基团;L1是一个共价键或连接原子或基团;n为零或整数1;Alk1是一个可选择取代的脂肪链;R3是氢原子或可选择取代的杂脂肪、环脂肪、杂环脂肪、多环脂肪、杂多环脂肪、芳香或杂芳基团;以及它们的盐类、溶剂合物、水合物和N-氧化物。这些化合物能够抑制整合素与其配体的结合,并用于预防和治疗免疫或炎症性疾病,或涉及细胞不适当生长或迁移的疾病。
