  Degradation of Azaglycinamido Residues in Model Tripeptides Derived from Goserelin

  摘要：

  Three model tripeptides, N-acetyl-Tyr-Pro-azaGly-NH2 (NYPaG), Tyr-Pro-azaGly-NH2 (YPaG), and Tyr-Pro-Gly-NH2(YPG), were subjected to a systematic degradation study to get information about the degradation of the azaglycinamido residue. The degradation products were characterized with LC-MS. Main degradation products of NYPaG possess partially or totally eliminated azaglycinamido residues, while YPaG and YPG are exhibit cyclo(Tyr-Pro) formation, a diketopiperazine. The influence of the pH on the degradation rate constant k(obs) was investigated for NYPaG and YPaG in the pH range 0.4-11. An U-shaped profile with an inflexion around pH 9 was found for NYPaG while the degradation rate of YPaG was independent of the pH. NYPaG apparently was subject to proton-, solvent-, and hydroxyl-catalyzed degradation reactions whereas YPaG only underwent solvent-catalyzed reactions. Some influence of acetate and phosphate ions on k(obs) was found fur YPaG. Arrhenius plots of NYPaG and YPaG; were found to be linear.

  Design, synthesis and evaluation of novel metalloproteinase inhibitors based on l-tyrosine scaffold

  摘要：

  A series of novel L-tyrosine derivatives were designed, synthesized and assayed for their inhibitory activities on matrix metalloproteinase 2 (MMP-2) and histone deacetylase 8 (HDAC-8). The results showed that these L-tyrosine derivatives exhibited inhibitory profiles against MMP-2 and HDAC-8. The compounds 6h (IC50 = 0.013 +/- 0.001 mu M) and 6j (IC50 = 0.017 +/- 0.001 mu M) were equal potent MMP-2 inhibitors to the positive control NNGH (IC50 = 0.014 +/- 0.001 mu M). As for HDAC-8 inhibition, some of the hydroxamate compounds, such as 6d (IC50 = 3.6 +/- 0.2 mu M) and 6c (IC50 = 5.8 +/- 0.5 mu M), were equal potent to the positive control SAHA (IC50 = 1.6 +/- 0.1 mu M). Structure-activity relationships were also briefly discussed. (C) 2012 Elsevier Ltd. All rights reserved.

  p-Nitromandelic acid as a safety-catch linker for Boc/Bzl-SPPS of base-labile compounds like peptides and depsipeptides is described. This linker permits acidic removal of side-chain protection groups from the resin. For cleavage from the solid support, the p-nitro group was reduced with tin(II) chloride. After washing off the reducing agents, the (depsi)peptide acids with or without the side-chain protection schemes were obtained by microwave irradiation at 50 degrees C with 5% TFA in dioxane.
• Design of Peptidomimetics That Inhibit the Association of Phosphatidylinositol 3-Kinase with Platelet-Derived Growth Factor-β Receptor and Possess Cellular Activity

  Phosphorylated tyrosine residues of growth factor receptors that associate with intracellular proteins containing src-homology 2 (SH2) domains are integral components in several signal transduction pathways related to proliferative diseases such as cancer, atherosclerosis, and restenosis. In particular, a phosphorylated pentapeptide [pTyr(751)-Val-Pro-Met(754)-Leu (PTyr = phosphotyrosine)] derived from the primary sequence of platelet-derived growth factor-beta (PDGF-beta) receptor blocks the association of the C-terminal SH2 domain of the p85 subunit of phosphatidylinositol 3-kinase (PI 3-kinase) to PDGF-beta receptor with an IC50 of 0.445 +/- 0.047 mu M. Further evaluation of the structure-activity relationships for pTyr(751)-Val-Pro-Met-Leu resulted in the design of smaller peptidomimetics with enhanced affinity including Ac-pTyr-Val-Ala-N(C6H13)(2) (IC50 = 0.076 +/- 0.010 mu M). In addition, the phosphotyrosine residue was replaced with a difluorophosphonate derivative [4-phosphono(difluoromethyl)phenylalanine (CF(2)Pmp)] which has been shown to be stable to cellular phosphatases. The extracellular administration of either CF(2)Pmp-Val-Pro-Met-Leu or Ac-CF(2)Pmp-Val-Pro-Met-NH2 in a whole cell assay resulted in specific inhibition of the PDGF-stimulated association from the C-terminal SH2 domain of the p85 subunit of PI 3-kinase to the PDGF-beta receptor in a dose-dependent manner. These compounds were also effective in inhibiting GLUT4 translocation, c-fos expression, and cell membrane ruffling in single-cell microinjection assay.
