  小磷酸肽，Grb2 SH2域抑制剂及其前药的构效关系。

  摘要：

  为开发针对癌症中HER2 / ErbB2过表达的潜在抗肿瘤药，我们设计了受体的磷酸酪氨酸与衔接蛋白Grb2的SH2结构域之间的识别抑制剂。在本文的第一部分中，我们报告了受约束的（α-Me）磷酸酪氨酸残基类似物的合成，例如（α-Me）-4-膦酰基甲基苯丙氨酸（-CH2PO3H2），（α-Me）4-膦酰基二氟甲基苯丙氨酸（- CF2PO3H2）和（α-Me）-4-膦酰基苯丙氨酸（-PO3H2）。这些残基在mAZ-pTyr-Xaa-Asn-NH2系列中的结合提供了对Grb2 SH2域具有非常高亲和力的化合物，其Kd值在10（-8）-10（-9）范围内。这些化合物可作为Grb2-Shc相互作用的有效拮抗剂。我们的结果强调了根据在mAZ-pTyr-（alphaMe）pTyr-Asn-NH2和Grb2 SH2域之间结晶的复合物中观察到的相互作用，由pY +1个氨基酸携带的双负电荷的重要性。mAZ-pT

  Concise and Enantioselective Synthesis of Fmoc-Pmp(Bu^t)₂-OH and Design of Potent Pmp-Containing Grb2-SH2 Domain Antagonists

  摘要：

  L-Phosphonomethylphenylalanine (L-Pmp) is an important phosphatase-resistant pTyr analogue. A most concise and stereoselective approach to the synthesis of the suitably protected Fmoc-Pmp(Bu-t)(2)-OH was developed in order to incorporate the functionally significant L-Pmp residue into peptides and peptidomimetics efficiently using standard Fmoc protocol. With this key building block, we are able to efficiently synthesize a series of potent Pmp-containing Grb2-SH2 domain antagonists, which can be used as chemotherapeutic leads for the treatment of erbB2-overexpressed breast cancer.

  enzymatic resolution of ethyl 4-[(dimethylphosphono)methyl]-D,L-phenylalaninate succeeded. These results are discussed by comparison with the literature data. The L and D amino acids were used to prepare separately, through solid-phase peptide synthesis, followed by deprotection of dimethylphosphonate group by trimethylsilyliodide (TMSI) in acetonitrile, the L and D isomers of Glu-Asp-Val- Pmp-Glu-Asn-Leu-His-Thr

  日期：2007.5

  Novel 1,4-benzodiazepine compounds were synthesized and evaluated for their ability to inhibit the proliferation of tumor cells. Some compounds revealed activities in the micromolar range and were more efficient than reference compound Ro 5-4864. Preliminary SAR helped to identify critical motifs for antiproliferative activity and led to the discovery of a compound selective for a melanoma cell line, known for its resistance to chemotherapy.
