    • Squaric acid derivatives of formula (1) are described: wherein Het is an optionally substituted bicyclic fused ring heteroaromatic group; L2 is a covalent bond or an atom or group —O—, —S—, —C(O)—, —C(S)—, —S(O)—, —S(O)2, —N(R8)— or —C(R8)(R8a)—; Ar2 is an optionally substituted aromatic or heteroaromatic group; Alk is a chain  in which R is a carboxylic acid (—CO2H) or a derivative or biostere thereof; R1 is a hydrogen atom or a C1-6alkyl group; L1 is a covalent bond or a linker atom or group; Alk1 is an optionally substituted aliphatic chain; n is zero or the integer 1; R2 is a hydrogen atom or an optionally substituted heteroaliphatic, cycloaliphatic, heterocycloaliphatic, polycycloalphatic, heteropolycycloaliphatic, aromatic or heteroaromatic group other than a 2,6-naphthyridin-1-yl, isoquinolin-1-yl, 2,7-naphthyridin-1-yl or quinazolin-4-yl 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.
    • 描述式(1)的方酸衍生物:其中Het是任选取代的双环稠环杂芳族基团; L 2是共价键或-O - , - S - , - C(O) - , -C(S) - , - S(O) - , - S(O)2,-N(R 8) - 或-C(R 8)(R 8a) - ; Ar 2 >是任选取代的芳族或杂芳族基团; Alk是一种链霉素,其中R是羧酸(-CO 2 H)或其衍生物或生物试剂; R 1是氢原子或C 1-6烷基; L 1, 是共价键或连接原子或基团; Alk 1是任选取代的脂族链; n是0或整数1; R 2是氢原子或任选取代的杂脂肪族,脂环族,杂脂族,多环烷基, 除2,6-二氮杂萘-1-基,异喹啉-1-基,2,7-萘啶-1-基或喹唑啉-4-基之外的杂多环脂族,芳族或杂芳族基;以及盐,溶剂合物,水合物和 N-氧化物。化合物能够抑制整联蛋白与其配体的结合 并且可用于预防和治疗免疫或炎性疾病或涉及细胞不适当生长或迁移的病症。
