  Total Synthesis of the Anti Methicillin-Resistant Staphylococcus aureus Peptide Antibiotics TAN-1057A-D

  摘要：

  TAN-1057A-D, dipeptides isolated from bacteria Flexibacter sp. PK-74 and PK-176, are new antibiotics with potent antibacterial activity against methicillin-resistant Staphylococcus aureus. We describe, in detail, the total synthesis of TAN-l057A-D by a convergent route featuring a new method to construct the cyclic amidinourea functional group.

  In this second paper in a series of three studies of stable analogs of thymopentin (Arg1-Lys2-Asp3-Val4-Tyr5), the synthesis of analogs stabilized at peptide bonds 1,2 and 3,4 via insertion of ketomethylene units is described. A tris(carbobenzyloxy)arginyl(k)norleucine pseudopeptide was synthesized and coupled to Asp-Val-Phe-resin units followed by HF cleavage to prepare Arg(k)Nle-Asp-Val-Phe analogs

  在第二篇论文中，对胸腺五肽（Arg1-Lys2-Asp3-Val4-Tyr5）的稳定类似物进行了三项研究，描述了通过插入酮亚甲基单元稳定在肽键1,2和3,4上的类似物的合成。合成了三（羰基苄氧基）精氨酰基（k）正亮氨酸假肽，并偶联至Asp-Val-Phe-树脂单元，然后进行HF裂解，以制备Arg（k）Nle-Asp-Val-Phe类似物。N-BOC Asp（k）Val和N-BOC Asp（k）Ala单元的制备，然后偶联至Phe-或Tyr-树脂单元，提供了与树脂结合的拟三肽底物，用于附着各种精氨酰二肽。从树脂上裂解得到胸腺五肽的3，4-酮亚甲基稳定的假肽类似物。与胸腺五肽本身相比，Arg-Lys-Asp（k）Val-Phe和Arg-Lys-Asp（k）Val-Tyr类似物与CEM细胞的结合更为牢固。

  Enantiomerically pure N-2-Z-N-2-MeAsnOH [(S)-14], prepared in 8 steps (23% overall yield) from asparaginic acid, was first subjected to a Hofmann degradation with PhI(OCOCF3)(2) yielding (S)-N-2-Z-N-2-methyl-2,3-diaminopropanoic acid [N-2-Z-N-2-Me-L-A(2)pr, (S)-15], and this in turn was protected to give N-2-Z-N-3-Boc-N-2-Me-L-A(2)pr [(S)-17]. Condensation of (S)-17 with HN=C(SMe)NHCONH2 followed by removal of the tert-butoxycarbonyl protecting group, cyclization and hydrogenolytic removal of the Z-group gave the heterocycle of TAN-1057A [(S)-1] with an e.e. of 87 in 36% yield [from (S)-14]. Coupling of (S)-1 with (S)-tris-Z-beta-homoarginine (20a) in the presence of O-(7-azabenzotriazol-1-yl)-N,N,N',N'-tetramethyluronium hexafluorophosphate (HATU) and iPr(2)NEt in N,N-dimethyl-acetamide followed by hydrogenolysis afforded the most active A-diastereomer of the natural antibiotic TAN-1057 in 52% yield (from (S)-1 and 20a). Similarly, starting from (S)-1, a single diastereomer of the potent, less toxic TAN-1057A analogue 22b with a beta-lysine side chain has been prepared. All described synthetic steps do not require column chromatography for purification of the products. (C) 2004 Elsevier Ltd. All rights reserved.
