  Synthesis of Photophore and Fluorophore Modified O-Benzylserine Derivatives

  摘要：

  O-Benzylation of serine is one of the important protection methods for solid phase peptide synthesis. The utilities of the protection group may be indicated that chemical modifications for O-benzylserine will be utilized to make functional peptides on solid phase synthesis. Detailed studies for effective synthesis of photoreactive and fluorophore containing O-benzylserine derivatives without racemization were reported.

  T-cells, should, in theory, modulate the immune response. The cysteine protease Cathepsin S performs a fundamental step in antigen presentation and therefore represents an attractive target for inhibition. Herein, we report a series of potent and reversible Cathepsin S inhibitors based on dipeptide nitriles. These inhibitors show nanomolar inhibition of the target enzyme as well as cellular potency in

  免疫应答的特异性取决于外源蛋白的加工和抗原肽在细胞表面的呈递。从理论上讲，抑制抗原呈递以及随后激活T细胞应能调节免疫反应。半胱氨酸蛋白酶组织蛋白酶S在抗原呈递中执行基本步骤，因此代表了诱人的抑制靶标。本文中，我们报告了一系列基于二肽腈的有效且可逆的组织蛋白酶S抑制剂。这些抑制剂在人B细胞系中显示出对目标酶的纳摩尔抑制作用以及细胞效价。还报道了与组织蛋白酶S共结晶的可逆抑制剂的第一个X射线晶体结构。

  The synthesis and in vitro activities of a series of suceinyl-nitrile-based inhibitors of Cathepsin S are described. Several members of this class show nanomolar inhibition of the target enzyme as well as cellular potency. The inhibitors displaying the greatest potency contain N-alkyl substituted piperidine and pyrrolidine rings spiro-fused to the alpha-carbon of the P1 residue. (C) 2007 Elsevier Ltd.
