    作为疏水性五元环β-氨基酸(例如ACPC)的补充,β-糖氨基酸(β-SAA)作为折叠体和α/β嵌合肽的亲水性构件的应用越来越多。 Fmoc 保护的 β-SAA [例如 Fmoc-RibAFU(ip)-OH] 确实是有用的乐高元素,可用于 SPPS。本文介绍了去除 1,2-OH 异亚丙基保护基团以增加此类 SAA 的亲水性。我们首先使用 N 3 -RibAFU(ip)-OH 模型化合物来优化温和的脱保护条件。通过RP-HPLC监测1,2-OH游离产物N 3 -RibAFU- OH及其甲基糖苷甲酯N 3 -RibAFU(Me) -OMe的形成,发现50% TFA或8当量。甲醇中的 Amberlite IR-120 H +树脂是有效脱保护的最佳试剂。然后将这些条件成功地应用于嵌合寡肽的合成:-GG- X- GG-[X=RibAFU(ip)]。我们发现所建立的条件是有效的,同时足够温和,可以去除 1

    Using a combination of parallel and directed synthesis, the discovery of a highly potent and selective series of adenosine A3 agonists was achieved. High aqueous solubility, required for the intended parenteral route of administration, was achieved by the presence of one or two basic amine functional groups.

    We report the solid phase synthesis of -GG-X-GG- type alpha/beta-carbopeptoids incorporating RibAFU(ip) (1a, tX) or XylAFU(ip) (2a, cX) sugar amino acids. Though coupling efficacy is moderate, both the lengthier synthetic route using Fmoc derivative (e.g., Fmoc-RibAFU(ip)-OH) and the azido derivative (e.g., N3-RibAFU(ip)-OH) via Staudinger reaction with nBu3P can be successfully applied. Both X-ray

    On the basis of high binding affinity at the A(3) adenosine receptor of 3'-aminoadenosine derivatives with hydrogen bonding donor ability, novel 3'-ureidoadenosine analogues were synthesized from 1,2:5,6-di-O-isopropylidene-D-glucose in order to lead to stronger hydrogen bonding than the corresponding 3'-aminoadeno sine derivatives. However, the synthesized 3'-ureidoadenosine analogues were totally devoid of binding affinity, because 3'-urea moiety caused steric and electrostatic repulsions at the binding site of the A(3) adenosine receptor, leading to conformational distortion.

  • Orthogonal Activation of the Reengineered A<sub>3</sub> Adenosine Receptor (Neoceptor) Using Tailored Nucleoside Agonists

    An alternative approach to overcome the inherent lack of specificity of conventional agonist therapy can be the reengineering of the GPCRs and their agonists. A reengineered receptor ( neoceptor) could be selectively activated by a modified agonist, but not by the endogenous agonist. Assisted by rhodopsin-based molecular modeling, we pinpointed mutations of the A(3) adenosine receptor (AR) for selective affinity enhancement following complementary modifications of adenosine. Ribose modifications examined included, at 3' : amino, aminomethyl, azido, guanidino, ureido; and at 5' : uronamido, azidodeoxy. N-6-Variations included 3-iodobenzyl, 5-chloro-2-methyloxybenzyl, and methyl. An N-6-3-iodobenzyl-3'-ureido adenosine derivative 10 activated phospholipase C in COS-7 cells (EC50 = 0.18 mu M) or phospholipase D in chick primary cardiomyocytes, both mediated by a mutant ( H272E), but not the wild-type, A(3)AR. The affinity enhancements for 10 and the corresponding 3'-acetamidomethyl analogue 6 were > 100-fold and > 20-fold, respectively. 10 concentration-dependently protected cardiomyocytes transfected with the neoceptor against hypoxia. Unlike 10, adenosine activated the wild-type A(3)AR (EC50 of 1.0 mu M), but had no effect on the H272E mutant A(3)AR (100 mu M). Compound 10 was inactive at human A(1), A(2A), and A(2B)ARs. The orthogonal pair comprising an engineered receptor and a modified agonist should be useful for elucidating signaling pathways and could be therapeutically applied to diseases following organ-targeted delivery of the neoceptor gene.
