  Combination of Non-natural d-Amino Acid Derivatives and Allophenylnorstatine−Dimethylthioproline Scaffold in HIV Protease Inhibitors Have High Efficacy in Mutant HIV

  摘要：

  Several non-natural D-amino acid derivatives were introduced as P(2)/P(3) residues in allophenylnorstatine-containing (Apns; (2S,3S)-3-amino-2-hydroxy-4-phenylbutyric acid) HIV protease inhibitors. The synthetic analogues exhibited potent inhibitory activity against HIV-1 protease enzyme and HIV-1 replication in MT-4 cells. Structure-activity relationships revealed that D-cysteine or serine derivatives contributed to highly potent anti-HIV activities. Interestingly, anti-HIV activity of all the D-amino acid-introduced inhibitors was remarkably enhanced in their anti-HIV activities against a Nelfinavir-resistant clone, which has a D30N mutation in the protease, over that of the wild-type strain. HIV inhibitory activity of several analogues was moderately affected by an inclusion of alpha(1)-acid glycoprotein in the test medium.

  procedure for peptide‐bond formation is reported. Instead of activation of the carboxylic acid functionality, the reaction involves an unprecedented use of activated α‐aminoesters. The method provides a straightforward entry to dipeptides and was effective when a sensitive cysteine residue was used, as no epimerization was detected in this case. The applicability of this method to iterative peptide synthesis

  报道了一种温和，实用和简单的肽键形成步骤。除了活化羧酸官能团之外，该反应还涉及前所未有的活化α-氨基酯的使用。该方法提供了直接进入二肽的方法，并且在使用敏感的半胱氨酸残基时有效，因为在这种情况下未检测到差向异构。通过在具有挑战性的N→C方向上合成模型四肽，说明了该方法在迭代肽合成中的适用性。

  solid-phase synthesis of the D-Cys6 analogues of arginine-vasopressin (AVP), peptide 1, of the selective AVP vasopressor (V1a receptor) antagonist [1-(beta-mercapto-beta,beta-pentamethylenepropionic acid),2-O-methyltyrosine]arginine-vasopressin (d(CH2)5[Tyr(Me)2]-AVP, (A)), peptide 2, of the three nonselective antidiuretic/vasopressor (V2/V1a receptor) AVP antagonists d(CH2)5[Tyr(Et)2]VAVP (B), d(CH2)5[D-Tyr(Et)2]VAVP

  我们还介绍了先前报道的d（CH2）5 [D-Trp2] AVT（肽10）及其D-Cys6类似物（肽11）（其中AVT =精氨酸-血管生成素）的重复合成。在体内V1a，V2和催产测定中以及在不使用0.5 mM Mg2 +和使用0.5 mM Mg2 +进行体外催产测定中，测定了肽1-11的激动和拮抗活性。由于V2和V1a的激动效力为0.82和0.41单位/毫克，[D-Cys6] AVP保留了不到0.3％的AVP V2和V1a效力。它不表现出催产活性，是一种体外OT拮抗剂。pA2 = 6.67（不含Mg2 +）；pA2 = 5.24（0.5 mM Mg2 +）。相比之下，除了一个或两个例外，拮抗剂2-9中的D-Cys6 / L-Cys6互换，尽管导致在所有测定中相对于AH而言几乎所有肽2-9的拮抗效力均降低，但已被很好地耐受。对于2-5肽，抗V2和抗V1a pA2值分别在约5.54至7.33和7

  7‐epi‐Taxane has been achieved efficiently in gram scale from natural taxane via inversion of the 7‐hydroxyl group simply using Ag2O as catalyst and DMF as solvent. The catalyst could be quantitatively recovered by filtration without loss of catalytic activity. This condition is also applicable to the direct epimerization of taxane derivatives (e.g., docetaxel and paclitaxel) to 7‐epi‐taxane derivatives
