    A 2,6,9-hetero-trisubstituted purine inhibitor exhibits potent biological effects against multiple myeloma cells
    摘要:
    A focused library of hetero-trisubstituted purines was developed for improving the cell penetrating and biological efficacy of a series of anti-Stat3 protein inhibitors. From this SAR study, lead agent 22e was identified as being a promising inhibitor of MM tumour cells (IC50's <5 mu M). Surprisingly, biophysical and biochemical characterization proved that 22e was not a Stat3 inhibitor. Initial screening against the kinome, prompted by the purine scaffold's history for targeting ATP binding pockets, suggests possible targeting of the JAK family kinases, as well for ABL1 (nonphosphorylated F317L) and AAK1.

    提出了一种2,6,9-三取代嘌呤的简便,有效和温和的合成方法,从市售的2-氨基-6-氯嘌呤开始,其采用先后顺序的N9然后N2 Mitsunobu反应作为关键步骤。重要的是,我们对嘌呤核进行N2官能化的合成方法消除了用伯胺将2-卤基团进行传统亲核芳香取代所需要的苛刻条件。在两次光延反应中,苯甲酸,烯丙基,炔丙基和脂肪族醇的收率都非常好。显着地,对于第一次偶联观察到优异的化学选择性和N9-区域选择性,并且在室温下15分钟内反应完成。我们新颖的方法很容易适应提供N 9-单-或N2,N 9-二官能化的鸟嘌呤类似物,并且我们的方案的实用性通过CDK抑制剂波西米因的有效合成得到进一步证明。

  • 8-Triazolylpurines: Towards Fluorescent Inhibitors of the MDM2/p53 Interaction

    Small molecule nonpeptidic mimics of α-helices are widely recognised as protein-protein interaction (PPIs) inhibitors. Protein-protein interactions mediate virtually all important regulatory pathways in a cell, and the ability to control and modulate PPIs is therefore of great significance to basic biology, where controlled disruption of protein networks is key to understanding network connectivity and function. We have designed and synthesised two series of 2,6,9-substituted 8-triazolylpurines as α-helix mimetics. The first series was designed based on low energy conformations but did not display any biological activity in a biochemical fluorescence polarisation assay targeting MDM2/p53. Although solution NMR conformation studies demonstrated that such molecules could mimic the topography of an α-helix, docking studies indicated that the same compounds were not optimal as inhibitors for the MDM2/p53 interaction. A new series of 8-triazolylpurines was designed based on a combination of docking studies and analysis of recently published inhibitors. The best compound displayed low micromolar inhibitory activity towards MDM2/p53 in a biochemical fluorescence polarisation assay. In order to evaluate the applicability of these compounds as biologically active and intrinsically fluorescent probes, their absorption/emission properties were measured. The compounds display fluorescent properties with quantum yields up to 50%.
    小分子非肽类α-螺旋模拟物被广泛认可为蛋白质-蛋白质相互作用(PPIs)的抑制剂。蛋白质-蛋白质相互作用几乎介导了细胞内所有重要的调控通路,因此控制和调节PPIs的能力对基础生物学具有重大意义,其中对蛋白质网络的可控破坏是理解网络连接和功能的关键。我们设计和合成了两系列2,6,9-取代的8-三唑基嘌呤作为α-螺旋模拟物。第一系列基于低能构象设计,但在针对MDM2/p53的生物化学荧光偏振分析中未显示出任何生物活性。尽管溶液NMR构象研究表明这些分子可以模拟α-螺旋的拓扑结构,但对接研究表明这些化合物作为MDM2/p53相互作用的抑制剂并不最优。基于对接研究和最近发表的抑制剂分析,设计了新的8-三唑基嘌呤系列。最佳化合物在生物化学荧光偏振分析中显示出对MDM2/p53的低微摩尔抑制活性。为了评估这些化合物作为具有内在荧光活性的探针的适用性,测量了它们的吸收/发射特性。这些化合物显示出高达50%的量子产率的荧光特性。

    An efficient, high yielding, chemo- and regioselective, five-step synthetic route to N2-Cbz-guanin-9-yl acetic acid has been developed, which avoids the use of triphosgene. After formation of the N2-Boc protected purine from 2-amino-6-chloropurine, two successive base-controlled alkylations allowed an N9-tert-butyl acetate function followed by an N2-Cbz moiety to be installed. The selectivities of
