    • Disclosed are compounds for SH2 domain binding inhibition. For example, disclosed is a compound of formula (I) wherein R1 is a lipophile; R2, in combination with the phenyl ring, is a phenylphosphate mimic group or a protected phenylphosphate mimic group; R3 is hydrogen, azido, amino, carboxyalkyl, alkoxycarbonylalkyl, aminocarbonylalkyl, or alkylcarbonylamino, wherein the alkyl portion of R3 may be optionally substituted with a substituent selected from the group consisting of halo, hydroxy, carboxyl, amino, aminoalkyl, alkyl, alkoxy, and keto; R6 is a linker; AA is an amino acid; and n is 1 to 6; or a salt thereof. The compounds of the present invention have the advantage that their conformation is constrained to provide enhanced binding affinity with SH2 domain protein. Also disclosed are a pharmaceutical composition comprising a pharmaceutically or pharmacologically acceptable carrier and a compound of the present invention, a method for inhibiting an SH2 domain from binding with a phosphoprotein comprising contacting an SH2 domain with a compound of the present invention, a method of preventing or treating a disease, state, or condition by the use of one or more of these compounds, and a method for preparing the compounds of the present invention. The present invention further provides intermediates useful in the preparation of the compounds.
    • 公开了用于SH2结构域结合抑制的化合物。 例如,公开了式(I)的化合物,其中R 1是亲油体; R2与苯环组合是苯基磷酸酯模拟基团或被保护的苯基磷酸酯模拟基团; R 3是氢,叠氮基,氨基,羧基烷基,烷氧基羰基烷基,氨基羰基烷基或烷基羰基氨基,其中R3的烷基部分可以任选地被选自卤素,羟基,羧基,氨基,氨基烷基,烷基,烷氧基, 和酮 R6是连接体; AA是氨基酸; n为1〜6; 或其盐。 本发明的化合物具有这样的优点:它们的构象被限制以提供与SH2结构域蛋白质的增强的结合亲和力。 还公开了包含药学上可接受的载体和本发明化合物的药物组合物,一种抑制SH2结构域与磷蛋白结合的方法,包括使SH2结构域与本发明的化合物接触,一种预防 或通过使用一种或多种这些化合物治疗疾病,状态或病症,以及制备本发明化合物的方法。 本发明还提供可用于制备化合物的中间体。
