Compounds of formula (1) are described:
wherein
L1 is a covalent bond or a linker atom or group;
R is a carboxylic acid (—CO2H) or a derivative threof;
R6 and R7 which may be the same or different is each an atom or group —L2(Alk2)tL3R12 in which L2, L3, Alk2 and t are as previously defined and R12 is a hydrogen or halogen atom or an —OR9, —NR9R10, —NO2, —CN, —CO2R9, —CONR9R10, —COR9, —N(R9)COR10, —N(R9)CSR10, —SO2N(R9)(R10), —N(R9)SO2R9, —N(R9)CON(R10)(R11), —N(R9)CSN(R10)(R11), —N(R9)SO2N(R10)(R11), or an optionally substituted aliphatic, heteroaliphatic, cycloaliphatic, heterocycloaliphatic, aromatic or heteroaromatic group provided that R6 and R7 are not both hydrogen atoms and when R7 is a hydrogen atom then R4 and R5 is each a hydrogen or halogen atom or an alkyl, alkoxy or nitro group; and the salts, solvates, hydrates and N-oxides thereof, for use in modulating cell adhesion.
The compounds are able to inhibit the binding of alpha 4 integrins to their ligands and are of use in the prophylaxis and treatment of immune or inflammatory disorders.
描述了化合物的公式(1):其中L1是共价键或连接器原子或基团;R是羧酸(-CO2H)或其衍生物;R6和R7可以相同也可以不同,分别是一个原子或基团-L2(Alk2)tL3R12,其中L2,L3,Alk2和t如先前所定义,R12是氢或卤素原子或-OR9,-NR9R10,-NO2,-CN,-CO2R9,-CONR9R10,-COR9,-N(R9)COR10,-N(R9)CSR10,-SO2N(R9)(R10),-N(R9)SO2R9,-N(R9)CON(R10)(R11),-N(R9)CSN(R10)(R11),-N(R9)SO2N(R10)(R11)或一个可选择取代的脂肪族,杂原子脂肪族,环脂肪族,杂环脂肪族,芳香族或杂芳香族基团,前提是R6和R7不都是氢原子,当R7是氢原子时,R4和R5分别是氢或卤素原子或烷基,烷氧基或硝基基团;以及其盐,溶剂化合物,水合物和N-氧化物,用于调节细胞粘附。这些化合物能够抑制α4整合素与其配体的结合,并可用于预防和治疗免疫或炎症性疾病。
