  Structure–Activity Relationships and Blood Distribution of Antiplasmodial Aminopeptidase-1 Inhibitors

  摘要：

  Malaria is a severe infectious disease that causes between 655 000 and 1.2 million deaths annually. To overcome the resistance to current drugs, new biological targets are needed for drug development. Aminopeptidase M1 (PfAM1), a zinc metalloprotease, has been proposed as a new drug target to fight malaria. Herein, we disclosed the structure-activity relationships of a selective family of hydroxamate PfAM1 inhibitors based on the malonic template. In particular, we performed a "fluoro-scanning" around hit 1 that enlightened the key positions of the halogen for activity. The docking of the best inhibitor 2 is consistent with in vitro results. The stability of 2 was evaluated in microsomes, in plasma, and toward glutathione. The in vivo distribution study performed with the nanomolar hydroxamate inhibitor 2 (BDM14471) revealed that it reaches its site of action. However, it fails to kill the parasite at concentrations relevant to the enzymatic inhibitory potency, suggesting that killing the parasite remains a challenge for potent and druglike catalytic-site binding PfAM1 inhibitors. In all, this study provides important insights for the design of inhibitors of PfAM1 and the validity of this target.

  铑催化烯烃与二氧化碳的加氢羧化反应

  摘要：

  探索了在空气稳定的铑催化剂存在下，苯乙烯衍生物和 α,β-不饱和羰基化合物与 CO2 (101.3 kPa) 的催化加氢羧化反应。[RhCl(cod)]2 (cod = cyclooctadiene) 作为催化剂和二乙基锌作为氢化物源的组合允许有效的加氢羧化并以中等至极好的产率提供相应的α-芳基羧酸。在这个使用二氧化碳的催化过程中，可以从 RhI 催化剂和二乙基锌产生的 RhI-H 物种的干预得到澄清。值得注意的是，α,β-不饱和酯与二氧化碳的催化不对称加氢羧化反应也通过使用含有 (S)-(-)-4,4'-bi-1,3-benzodioxole-5 的阳离子铑络合物进行，5'-二基双（二苯基膦）[(S)-SEGPHOS] 作为手性二膦配体。通过确定产品的绝对构型，提出了一个合理的不对称归纳模型。

  Hydroxamic acids are outstanding zinc chelating groups that can be used to design potent and selective metalloenzyme inhibitors in various therapeutic areas. Some hydroxamic acids display a high plasma clearance resulting in poor in vivo activity, though they may be very potent compounds in vitro. We designed a 57-member library of hydroxamic acids to explore the structure–plasma stability relationships

  异羟肟酸是杰出的锌螯合基团，可用于设计各种治疗领域中的有效和选择性金属酶抑制剂。一些异羟肟酸显示出较高的血浆清除率，导致体内活性差，尽管它们在体外可能是非常有效的化合物。我们设计了一个由57名成员组成的异羟肟酸文库，以探索这些系列中结构与血浆的稳定性关系，并确定哪些酶和哪些药效团对血浆稳定性至关重要。芳基酯酶和羧酸酯酶被确定为异羟肟酸的主要代谢酶。最后，我们建议引入或删除结构特征以提高稳定性。因此，这项工作提供了第一个药物化学工具箱（实验程序和结构指导），用于评估和控制异羟肟酸的血浆稳定性，并充分发挥其作为体内药理探针和治疗剂的潜力。这项研究与临床前开发特别相关，因为它允许获得在人和啮齿动物模型中同样稳定的化合物。

  display nanomolar activities against metalloproteases, only three hydroxamates have reached the market, among which is the HDAC inhibitor vorinostat. Failures in development are generally attributed to lack of selectivity, toxicity, or poor stability. To help medicinal chemists with respect to plasma stability, we have performed the first and preliminary study on structure−plasma stability for hydroxamates

  异羟肟酸酯是用于化学生物学的有价值的工具，也是用于药物化学的有趣线索。尽管许多异羟肟酸酯显示出对金属蛋白酶的纳摩尔活性，但只有三种异羟肟酸酯进入市场，其中包括HDAC抑制剂伏立诺他。开发失败通常归因于缺乏选择性，毒性或稳定性差。为了帮助药用化学家进行血浆稳定性方面的研究，我们对异羟肟酸酯的结构-血浆稳定性进行了首次和初步研究。我们定义一些结构规则，以预测或改善临床前阶段的血浆稳定性。
• An improved solvent-free system for the microwave-assisted decarboxylation of malonate derivatives based on the use of imidazole

  A comparative study of the thermal and microwave-assisted decarboxylation of a series of mono- and disubstituted monohydrolyzed malonate derivatives has been carried out. It has been found out that in both circumstances the use of imidazole has a profound effect on the success of the reaction. In general terms the assistance of microwave irradiation accelerates the decarboxylation process significantly and, at the same time, permits the use of minored temperatures with respect to the thermal via. It has been also found that both the thermal and the microwave-assisted transformation can be developed under solvent-free conditions. (C) 2015 Elsevier Ltd. All rights reserved.

• Bis-Substituted Malonic Acid Hydroxamate Derivatives as Inhibitors of Human Neutrophil Collagenase (MMP8)

  Malonic acid hydroxamate derivatives bis-substituted at the methylene group were synthesized as potential nonpeptidic inhibitors of human neutrophil collagenase (MMP8). The presence of an aromatic residue both at the C2 malonic acid position and in the C-terminal tail for hydrophobic interactions with the surface-exposed S1 binding site and the S1' pocket of the enzyme, respectively, was found to be sufficient for submicromolar inhibition potencies. For optimal insertion of the aryl amide group into the hydrophobic S1' pocket, spacing of the C-terminal phenyl group by at least a SC-chain was required. In view of these results the achiral indan-2,2-dicarboxylic acid was used to mimic the 2-benzyl-2-methylmalonic acid residue, and its derivatization to the 3-phenylpropyl amide hydroxamate produced a potent, achiral, low-mass inhibitor of MMP8 (K-i = 0.3 mu M), the binding mode of which was unambiguously determined by X-ray crystallographic analysis.
