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.
本发明涉及用于SH2结构域结合抑制的化合物。例如,本发明揭示了一种式(I)的化合物,其中R1是脂肪族;R2与苯环结合,是苯基磷酸酯类似物基团或保护的苯基磷酸酯类似物基团;R3是氢、叠氮基、氨基、羧基烷基、烷氧羰基烷基、氨基羰基烷基或烷基羰基氨基,其中R3的烷基部分可以选择地被取代为从卤素、羟基、羧基、氨基、氨基烷基、烷基、烷氧基和酮中选择的取代基;R6是连接子;AA是氨基酸;n为1至6;或其盐。本发明的化合物具有优点,其构象被限制以提供与SH2结构域蛋白的增强结合亲和力。本发明还揭示了一种制备本发明化合物的中间体,以及包括药学或药理学可接受载体和本发明化合物的制药组合物、通过使用这些化合物中的一种或多种来预防或治疗疾病、状态或病况的方法,以及通过将SH2结构域与本发明化合物接触来抑制SH2结构域与磷酸化蛋白结合的方法。
