  Discovery of Dipeptides with High Affinity to the Specific Binding Site for Substance P₁₋₇

  摘要：

  Substance P 1-7 (SP1-7, H-Arg-Pro-Lys-Pro-Gln-Gln-Phe-OH) is the major bioactive metabolite of substance P. The interest in this heptapeptide originates from the observation that it modulates, and in certain cases opposes the effects of the parent peptide. e.g., the nociceptive effect. The p-opioid receptor agonist endomorphin-2 (EM-2, H-Tyr-Pro-Phe-Phe-NH2) has been found to also interact with the specific binding site of SP1-7 with only a 10-fold lower affinity compared to the native peptide. Considering the smaller size of EM-2 compared to the target heptapeptide, it was selected as a lead compound in the development of low-molecular-weight ligands to the SP1-7 binding site. An alanine scan and truncation study led to the unexpected discovery of the dipeptide H-Phe-Phe-NH2 (K-i = 1.5 nM), having equal affinity as the endogenous heptapeptide SP1-7. Moreover, the studies show that the C-terminal phenylalanine amide is crucial for the affinity of the dipeptide.

  Novel Selective Inhibitors of the Interaction of Individual Nuclear Hormone Receptors with a Mutually Shared Steroid Receptor Coactivator 2

  摘要：

  Nuclear hormone receptor (NR) signaling, currently a therapeutic target in multiple diseases, involves an ordered series of protein interactions to regulate transcription in response to changing hormone levels. Later steps in the process of ligand-dependent signaling are driven by a highly conserved interaction between the NRs and the steroid receptor coactivators (SRCs) that is effected by a conserved interaction motif (L1XXL2L3), known as an NR box. Using computational design and combinatorial chemistry, we have produced novel alpha-helical proteomimetics of the second NR box of SRC2 that exploit structural differences between human estrogen receptor alpha (hERalpha), human estrogen receptor beta (hERbeta), and human thyroid hormone receptor beta (hTRbeta). The resulting library sequentially replaced each leucine with non-natural side chains. Screening this library using a quantitative competition assay revealed compounds that selectively inhibit the interaction of SRC2-2 with each individual NR in preference to its interaction with the other NR. This approach generated highly selective compounds from one that had no specificity for a particular family member. These compounds represent the first family-member-selective competitive inhibitors of the protein interactions of transcription factors.

  The use of ligands to tune the reactivity and selectivity of transition metal-catalysts for C(-sp3)-H bond functionalization is a central challenge in synthetic organic chemistry. Herein, we report a rare example of catalyst-controlled C(sp3)-H arylation using pyridine and quinoline derivatives: the former promotes exclusive monoarylation, whereas the latter activates the catalyst further to achieve diarylation. Successive application of these ligands enables the sequential diarylation of a methyl group in an alanine derivative with two different aryl iodides, affording a wide range of β-Ar-p-Ar ' -cc-amino acids with excellent levels of diastereoselectivity (d.r. > 20:1). Both configurations of the β-chiral center can be accessed by choosing the order in which the aryl groups are installed. The use of a quinoline derivative as a ligand also enables C(sp3)-H olefination of a protected alanine.

  使用配体调节过渡金属催化剂对C(-sp3)-H键官能化的反应性和选择性是合成有机化学中的一个核心挑战。在这里，我们报告了一个罕见的催化剂控制的C(sp3)-H芳基化的例子，使用吡啶和喹啉衍生物：前者促进了独特的单芳基化，而后者进一步激活了催化剂以实现二芳基化。这些配体的连续应用使得在丙氨酸衍生物中的甲基基团上进行顺序二芳基化成为可能，使用两种不同的芳基碘化物，得到了一系列具有优异立体选择性的β-Ar-p-Ar' -cc-氨基酸（d.r. > 20:1）。通过选择芳基基团的安装顺序，可以访问β-手性中心的两种构型。使用喹啉衍生物作为配体还可以实现保护丙氨酸的C(sp3)-H烯烃化。

  The present invention relates to methods for identifying compounds capable of modulating a cellular response. The methods involve attaching living cells to solid supports comprising a library of test compounds. The test compounds are linked to the solid support via cleavable linkers and may thus be released from the solid supports. Solid supports comprising cells, wherein the cellular response of interest has been modulated are selected and the test compound of the solid support can then be identified. The cellular response may for example be changes in complex formation between proteins.
