Phenylalanine enamide derivatives of formula (1) are described:
1
wherein
R
1
is a group Ar
1
L
2
Ar
2
Alk- in which:
Ar
1
is an optionally substituted aromatic or heteroaromatic group;
L
2
is a covalent bond or a linker atom or group;
Ar
2
is an optionally substituted arylene or heteroarylene group; and Alk is a chain —CH
2
—CH(R)13 , —CH═C(R)— or
2
in which
R is a carboxylic acid (—CO
2
H) or a derivative or biostere thereof;
X is an —O— or —S— atom or —N(R
2
)— group in which:
R
x
, R
y
and R
z
which may be the same or different is each a hydrogen atom or an optional substituent;
or R
z
is an atom or group as previously defined and R
x
and R
y
are joined together to form an optionally substituted spiro linked cycloaliphatic or heterocycloaliphatic 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 immuno or inflammatory disorders or disorders involving the inappropriate growth or migration of cells.
描述了公式(1)的苯丙氨酸烯酰胺衍生物:其中R1是Ar1L2Ar2Alk-中的一种基团,其中:Ar1是可选择取代的芳香族或杂环芳基;L2是一个共价键或连接原子或基团;Ar2是可选择取代的芳基或杂芳基;Alk是一个链-CH2-CH(R)13,-CH═C(R)-或2其中R是羧酸(-CO2H)或其衍生物或生物立体异构体;X是一个-O-或-S-原子或-N(R2)-基团,其中:Rx、Ry和Rz可能相同也可能不同,分别是氢原子或可选择取代基;或Rz是如前所定义的原子或基团,Rx和Ry结合在一起形成一个可选择取代的螺环联接的环脂肪族或杂环脂肪族基团;以及它们的盐、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,并可用于预防和治疗免疫或炎症性疾病或涉及细胞不当生长或迁移的疾病。
