  Nonpeptidic, Monocharged, Cell Permeable Ligands for the p56lck SH2 Domain

  摘要：

  p561ck is a member of the src family of tyrosine kinases and plays a critical role in the signal transduction events that lead to T cell activation. Ligands for the p561ck SH2 domain have the potential to disrupt the interaction of p561ck with its substrates and derail the signaling cascade that leads to the production of cytokines such as interleukin-2. Starting from the quintuply charged (at physiological pH) phosphorylated tetrapeptide, AcpYEEI, we recently disclosed (J. Med. Chem. 1999, 42, 722 and J. Med. Chem. 1999, 42, 1757) the design of the modified dipeptide 3, which carries just two charges at physiological pH. Here we present the elaboration of 3 to the nonpeptidic, monocharged compound, 9S. This molecule displays good binding affinity for the p561ck SH2 domain (K-d 1 muM) and good cell permeation, and this combination of properties allowed us to demonstrate clear-cut inhibitory effects on a very early event in T cell activation, namely calcium mobilization.

  proteins, we recently synthesized the new amino acids, p(CH2PO3H2)Phe and p(CH2SO3H)Phe (D,L mixtures) as chemically and enzymatically stable analogs of (O-phospho) and (O-sulfo)-tyrosine. Here, we report improved syntheses of these amino acids and of their N-Boc protected derivatives for use in solid-phase peptide synthesis. A protocol for their enzymatic resolution by use of subtilisin Carlsberg esterase

  为了分析酪氨酸在肽和蛋白质中的翻译后磷酸化和硫酸化的作用，我们最近合成了新的氨基酸p（CH 2 PO 3 H 2）Phe和p（CH 2 SO 3 H）Phe（D，L混合物）作为（O-磷酸）和（O-磺基）酪氨酸的化学和酶促稳定类似物。在这里，我们报告了这些氨基酸及其N-Boc保护的衍生物用于固相肽合成的合成方法的改进。开发了一种使用枯草杆菌蛋白酶嘉士伯酯酶进行酶解的方案，并将其扩展到修饰氨基酸p（CH 2 CO 2 H）-D，L-Phe和p（CH 2CONHOH）-D，L-Phe。通过手性相HPLC测试拆分的氨基酸的光学纯度。给出了这些氨基酸及其N-Boc衍生形式的物理常数，包括其在PTC形式下的表征（苯硫代氨基甲酰基）。
