Squaric acid Derivatives of formula (1) are described:
wherein
R1 is an integrin binding group;
R2 is a hydrogen atom or a C1-6alkyl group;
L1 is a covalent bond or a linker atom or group;
n is zero or the integer 1;
Alk1 is an optionally substituted aliphatic chain;
R3 is a hydrogen atom or an optionally substituted heteroaliphatic, cycloaliphatic, heterocycloaliphatic, polycycloaliphatic, polyheterocycloaliphatic, 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 of inflammatory disorders, or disorders involving the inappropriate growth or migration of cells.
方程式(1)的Squaric酸衍生物如下:其中R1是一个整合素结合基团;R2是氢原子或C1-6烷基基团;L1是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是氢原子或一个可选择取代的异脂肪、环脂肪、异环脂肪、多环脂肪、多异环脂肪、芳香或异芳香基团;它们的盐、溶剂化合物、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,并可用于预防和治疗免疫性或炎症性疾病,或涉及细胞异常生长或迁移的疾病。
