  Design and Evaluation of Hydroxamate Derivatives as Metal-Mediated Inhibitors of a Protein Tyrosine Kinase

  摘要：

  Protein tyrosine kinases use two Mg2+ ions as cofactors in catalysis, one as the ATP-Mg complex (M1) and the other as an essential activator (M2). The M2-binding site has high affinity for transition metal cations such as cobalt and zinc. Taking advantage of this high affinity, we examined hydroxamates as metal-mediated inhibitors against C-terminal Src kinase (Csk), a protein tyrosine kinase. Of a small group of amino acid hydroxamates, tyrosine and phenylalanine hydroxamates inhibited Csk activity only in the presence of Co2+. Four classes of phenylalanine and tyrosine hydroxamate derivatives were synthesized and evaluated as metal-mediated inhibitors of Csk, leading to improved inhibition and a better understanding of the structure-activity relationships. This study suggests that hydroxamates may serve as a general scaffold for developing metal-mediated inhibitors against protein tyrosine kinases. To the best of our knowledge, this is the first report of designing metal-mediated inhibitors against a protein tyrosine kinase by targeting a metal binding site.

  Interfacial Cavity Filling To Optimize CD4–Mimetic Miniprotein Interactions with HIV-1 Surface Glycoprotein

  摘要：

  Ligand affinities can be optimized by interfacial cavity filling. A hollow (Phe43 cavity) between HIV-1 surface glycoprotein (gp120) and cluster of differentiation 4 (CD4) receptor extends beyond residue phenylalanine 43 of CD4 and cannot be fully accessed by natural amino acids. To increase HIV-1 gp120 affinity for a family of CD4-mimetic miniproteins (miniCD4s), we targeted the gp120 Phe43 cavity with 11 nonnatural phenylalanine derivatives, introduced into a miniCD4 named M48 (1). The best derivative, named M48U12 (13), bound HIV-1 YU2 gp120 with 8 pM affinity and showed potent HIV-1 neutralization. It contained a methylcyclohexyl derivative of 4-aminophenylalanine, and its cocrystal structure. with gp120 revealed the cyclohexane ring buried within the gp120 hydrophobic core but able to assume multiple orientations in the binding pocket, and the aniline nitrogen potentially providing a focus for further improvement Altogether, the results provide a framework for filling the interfacial Phe43 cavity to enhance miniCD4 affinity.
