• Phase-transfer reagents as C-terminal protecting groups; facile incorporation of free amino acids or peptides into peptide sequences
  作者：Shui-Tein Chen、Kung-Tsung Wang

  DOI：10.1039/c39900001045

  日期：——

  Phase-transfer reagents (basic, neutral, and acidic) can effect temporary protection of carboxy groups by salt formation in C-terminal free amino acids or peptides during peptide synthesis; the use of acidic or neutral phase-transfer reagents as the C-terminal protecting group will not affect the nucleophilicity of the amino group of the salts thus prepared in an organic solvent.

  相转移试剂（碱性，中性和酸性）可通过在肽合成过程中在C端游离氨基酸或肽中形成盐来暂时保护羧基。使用酸性或中性相转移试剂作为C-末端保护基不会影响在有机溶剂中如此制得的盐的氨基的亲核性。

  18F-labeling of 5-(trifluoromethyl)-dibenzothiophenium trifluoromethanesulfonate, commonly referred to as the Umemoto reagent, has been accomplished applying a halogen exchange 18F-fluorination with 18F-fluoride, followed by oxidative cyclization with Oxone and trifluoromethanesulfonic anhydride. This new 18F-reagent allows for the direct chemoselective 18F-labeling of unmodified peptides at the thiol cysteine

  5-(三氟甲基)-二苯并噻吩三氟甲磺酸盐的 18F 标记，通常称为 Umemoto 试剂，已通过卤素交换 18F-氟化与 18F-氟化物，然后与 Oxone 和三氟甲磺酸酐氧化环化来完成。这种新的 18F 试剂允许在硫醇半胱氨酸残基处对未修饰的肽进行直接化学选择性 18F 标记。
• Design, synthesis, inhibitory activity, and SAR studies of pyrrolidine derivatives as neuraminidase inhibitors

  A series of pyrrolidine derivatives were synthesized and evaluated for their ability to inhibit neuraminidase (NA) of influenza A virus (H3N2). All compounds were synthesized in good yields starting from commercially 4-hydroXy-L-proline using a suitable synthetic strategy. These compounds showed potent inhibitory activity against influenza A neuraminidase. Within this series, five compounds, 6e, 9c, 9e, 9f, and 10e, have good potency (IC50 = 1.56-2.71 mu M) which are compared to that the NA inhibitor Oseltarnivir (IC50 = 1.06 mu M), and could be used as lead compoundS in the future.

• (3S)-N-(l-Aminoacyl)-1,2,3,4-tetrahydroisoquinolines, a class of novel antithrombotic agents: Synthesis, bioassay, 3D QSAR, and ADME analysis

  To increase antithrombotic activity, 3S-tetrahydroisoquinoline-3-carboxylic acid (1) was modified with natural amino acids to form 19 novel dipeptide analogs, 3S-tetrahydroisoquinoline-3-carboxyamino acids (5a-s), targeting the intestinal peptide transport system. In vitro assay of 5a-s indicated that their potencies for inhibiting adenosine diphosphate (ADP), arachidonic acid (AA), platelet-activating factor (PAF), and thrombin (TH)-induced platelet aggregations were higher than that of 1. Additionally, in vivo assay of 5a-s indicated that their potencies for inhibiting thrombogenesis in rats were also higher than that of 1. Among the candidates, 5h with Ser attachment showed the most impressive features for further development. According to molecular field analysis based Cerius(2) QSAR module, two equations (r, 0.961 and 0.988) correlating the structures with both in vitro and in vivo activities of 5a-s were established. ADMET calculations predict higher intestinal absorption for compounds 5a-s. Further investigation with 5h as a lead compound is underway. (C) 2008 Elsevier Ltd. All rights reserved.
