  The present invention relates to the field of regulating the activity of the purinergic receptors for the modulation of the vascular tone, particularly for the purpose of treatment of haemodynamic conditions by overriding of vasoconstriction activity, such as increases in sympathic vasoconstriction. Modulators, such as UTP analogues as described herein are preferably specific for P2Y2. Compounds capable of stimulating the P2Y2 receptor are suitable for the treatment or prevention wherein inhibition of vasoconstriction activity is desirable such as hypertension and hypertension relates disorders or diseases, whereas compound capable of counteracting the activity of the P2Y2 receptor are suitable for the treatment of or prevention wherein inhibition of vasodilatation is desirable.

  本发明涉及调节嘌呤能受体活性以调节血管张力的领域，特别是通过抑制血管收缩活性（如交感血管收缩增加）来治疗血流动力学疾病。调节剂，如本文所述的UTP 类似物，最好对 P2Y2 具有特异性。能够刺激 P2Y2 受体的化合物适用于治疗或预防需要抑制血管收缩活性的疾病，如高血压和高血压相关失调或疾病，而能够抵消 P2Y2 受体活性的化合物适用于治疗或预防需要抑制血管舒张的疾病。

  Maskless photolithographic peptide synthesis was performed on a glass chip using an automated peptide array synthesizer system. The peptide array synthesizer was built in a closed box, which contained optical and fluidic systems. The conditions for peptide synthesis were fully controlled by a computer program. For the peptide synthesis on a glass chip, 20 NVOC-protected amino acids were synthesized. The coupling efficiencies of two model peptide sequences were examined on ACA/APTS and PEG/CHI/GPTS chips. PEG/CHI/GPIS chip gave higher average stepwise yields of GIYWHHY (94%) and YIYGSFK (98%) than those of ACA/APTS chip. To quantify peptide-protein binding affinity, HPQ- or HPM-containing pentapeptides were synthesized on a PEG/CHI/GPTS chip and the binding event of Cy3 labeled-streptavidin was quantified. The peptide sequence of IQHPQ showed highest binding affinity with Cy3 labeled-streptavidin. The results demonstrated that the photolithographic peptide array synthesis method efficiently quantified the binding activities of protein-peptide interactions and it can be used for additional biological assay applications.
• Preparation of Translationally Competent tRNA by Direct Chemical Acylation
  作者：Noah H. Duffy、Dennis A. Dougherty

  DOI：10.1021/ol101408f

  日期：2010.9.3

  Nonsense codon suppression for unnatural amino acid incorporation requires the preparation of a suppressor aminoacyl-tRNA. Chemical acylation strategies are general but inefficient and arduous. A recent report (J. Am. Chem. Soc. 2007, 129, 15848) showed acylation of RNA mediated by lanthanum(III) using amino acid phosphate esters. The successful implementation of this methodology to full-length suppressor tRNA is described, and it is shown that the derived aminoacyl-tRNA is translationally competent in Xenopus oocytes.
