  • Patent number: 7425537
    Abstract: Disclosed are compounds for SH2 domain binding inhibition, for example, 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 conformationally compounds provide enhanced binding affinity with SH2 domain protein. Also disclosed are a pharmaceutical compositions and a method for inhibiting an SH2 domain from binding with a phosphoprotein.

  • Patent number: 6977241
    Abstract: 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, forms 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. Also disclosed are a pharmaceutical composition, a method for inhibiting an SH2 domain from binding with a phosphoprotein and a method of treating breast cancer.
