    • The present invention provides phenylalanine derivatives that inhibit SH2 domain binding with a phosphoprotein. These derivatives include compounds of the formula: W—Y-(AA)n-Z wherein n is 0 to 15; Y is a phenylalanyl radical having a phenyl ring, an amine end, and a carboxyl end, the phenyl ring having one or more substituents, e.g., hydroxyl, carboxyl, formyl, carboxyalkyl, carboxyalkyloxy, dicarboxyalkyl, dicarboxyalkyloxy, dicarboxyhaloalkyl, dicarboxyhaloalkyloxy, and phosphonoalkyl, or phosphonohaloalkyl; W is a moiety attached to the nitrogen of Y and is, e.g., alkylcarbonyl, oxalyl, alkylaminooxalyl, arylaminooxalyl, arylalkylaminooxalyl, or alkoxyoxalyl; AA is an amino acid, the amine end of which is attached to the carboxyl end of Y; and Z is an arylalkylamino or arylheterocyclyl alkylamino; or a salt thereof; with the proviso that W is not arylalkylamino when the phenyl ring of phenylalanyl contains a phosphonoalkyl or phosphonohaloalkyl substituent at a position para to the alkylamido group and the ortho and meta positions are unsubstituted. The present invention further provides precursors suitable for preparing the phenylalanine derivatives and a method for the preparation of the precursors. The present invention further provides conjugates comprising a precursor and a conjugant that are covalently linked. These conjugates have biological and/or pharmacological properties.
    • 本发明提供抑制与磷蛋白结合的SH2结构域的苯丙氨酸衍生物。 这些衍生物包括下式的化合物:其中n为0至15的W-Y-(AA)n-Z; Y是具有苯环,胺末端和羧基端的苯丙氨酰基,苯环具有一个或多个取代基,例如羟基,羧基,甲酰基,羧基烷基,羧基烷氧基,二羧基烷基,二羧基烷氧基,二羧基卤代烷基,二羧基卤代烷氧基和膦酰基烷基 ,或膦酰卤代烷基; W是连接到Y的氮的部分,例如烷基羰基,草酰基,烷基氨基草酰基,芳基氨基草酰基,芳基烷基氨基草酰基或烷氧基草酰基; AA是氨基酸,其末端连接到Y的羧基末端; Z是芳基烷基氨基或芳基杂环基烷基氨基; 或其盐; 条件是当苯丙氨酰基的苯环在烷基酰氨基的对位位置含有膦酰基烷基或膦酰卤代烷基取代基时,W不是芳烷基氨基,邻位和间位是未取代的。 本发明还提供适用于制备苯丙氨酸衍生物的前体和前体的制备方法。 本发明进一步提供包含共价连接的前体和共轭物的缀合物。 这些缀合物具有生物学和/或药理学性质。
