  Rational design, synthesis and biological evaluation of novel multitargeting anti-AD iron chelators with potent MAO-B inhibitory and antioxidant activity

  摘要：

  A series of (3-hydroxypyridin-4-one)-coumarin hybrids were developed and investigated as potential multi targeting candidates for the treatment of Alzheimer's disease (AD) through the incorporation of iron-chelating and monoamine oxidase B (MAO-B) inhibition. This combination endowed the hybrids with good capacity to inhibit MAO-B as well as excellent iron-chelating effects. The pFe(3+) values of the compounds were ranging from 16.91 to 20.16, comparable to more potent than the reference drug deferiprone (DFP). Among them, compound 18d exhibited the most promising activity against MAO-B, with an IC50 value of 87.9 nM. Moreover, compound 18d exerted favorable antioxidant activity, significantly reversed the amyloid-beta(1-42) (A beta(1-42)) induced PC12 cell damage. More importantly, 18d remarkably ameliorated the cognitive dysfunction in a scopolamine-induced mice AD model. In brief, a series of hybrids with potential anti-AD effect were successfully obtained, indicating that the design of iron chelators with MAO-B inhibitory and antioxidant activities is an attractive strategy against AD progression.

  摘要：

  摘要 通过基于先导化合物18d、苄氧基苯基类似物和去铁酮的药效团合并方法，创新地设计、合成和生物学评估了一类新的苯甲酰胺-羟基吡啶酮 (HPO) 衍生物作为治疗阿尔茨海默病 (AD) 的潜在多靶点候选药物(DFP)。这些杂种具有有效的单胺氧化酶 B (MAO-B) 抑制作用以及出色的铁螯合性，pFe 3+值范围为 18.13 至 19.39。在所有化合物中，8g表现出最有效的选择性 MAO-B 抑制剂（IC 50 = 68.4 nM，SI = 213）。此外，8g显示出良好的药代动力学特性，并具有巨大的穿透 BBB 的潜力计算机和 PAMPA-BBB 测定。分子模型表明，8g可以采用扩展构象，并且与 MAO-B 的相互作用比18d更强。体外和体内试验表明，8g显着抵抗 Aβ 诱导的氧化并改善东莨菪碱诱导的认知障碍。综上所述，这些结果表明化合物8g是一种潜在的多功能抗 AD 治疗候选药物。

  Gram-negative bacteria’s resistance such as Pseudomonas aeruginosa and the Burkholderia group to conventional antibiotics leads to therapeutic failure. Use of siderophores as Trojan horses to internalize antibacterial agents or toxic metals within bacteria is a promising strategy to overcome resistance phenomenon. To combat the Pseudomonas sp, we have synthesized and studied two piperazine-based siderophore mimetics carrying either catecholate moieties (1) or hydroxypyridinone groups (2) as iron chelators. These siderophore-like molecules were prepared in no more than four steps with good global yields. The physicochemical study has highlighted a strong iron affinity since their pFe values were higher than 20. 1 possesses even a pFe value superior than those of pyoverdine, the P. aeruginosa endogenous siderophore, suggesting its potential ability to compete with it. At physiological pH, 1 forms mainly a 2:3 complex with iron, whereas two species are observed for 2. Unfortunately, the corresponding Ga(III)-1 and 2 complexes showed no antibacterial activity against P. aeruginosa DSM 1117 strain. The evaluation of their siderophore-like activity showed that 1 and 2 could be internalized by the bacteria.

  革兰氏阴性细菌的抗药性，如铜绿假单胞菌和伯克霍尔德菌群对传统抗生素的抵抗导致治疗失败。利用铁载体作为特洛伊木马将抗菌剂或有毒金属内化到细菌内部是克服抵抗现象的一种有前景的策略。为了对抗铜绿假单胞菌，我们合成并研究了两种基于哌嗪的铁载体模拟物，分别携带邻苯二酚基团（1）或羟基吡啶酮基团（2）作为铁螯合剂。这些类似铁载体的分子在不超过四个步骤中制备，全球产率良好。物理化学研究强调了它们与铁的亲和力很强，因为它们的pFe值高于20。1甚至具有比铜绿假单胞菌内源性铁载体吡沃德因更高的pFe值，表明它有潜力与之竞争。在生理pH下，1主要形成与铁的2:3络合物，而2观察到两种物种。不幸的是，对应的Ga(III)-1和2络合物对铜绿假单胞菌DSM 1117菌株没有抗菌活性。它们的类似铁载体活性评估表明1和2可以被细菌内化。
