    A Fine-Tuned Lipophilicity/Hydrophilicity Ratio Governs Antibacterial Potency and Selectivity of Bifurcated Halogen Bond-Forming NBTIs
    摘要:
    在这里,我们报告了基于创新的主要单环右侧片段设计的新型细菌拓扑异构酶抑制剂(NBTIs)的库。这些片段对DNA旋转酶和Topo IV具有活性,表现出非常强大和广泛的抗菌活性,甚至对一些最令人担忧的难以治疗的病原体也有效,这些病原体迫切需要新的抗菌药物,正如世界卫生组织和疾病预防控制中心所报道的。NBTIs酶活性和整体细胞效力似乎取决于精细调节的亲脂性/亲水性比率,这个比率决定了这些化合物通过细菌膜的渗透性。NBTIs的亲脂性显然最适合通过革兰氏阳性细菌的膜,但更高的、尽管不过度的亲脂性和适当的亲水性似乎决定了通过革兰氏阴性细菌膜的通道。然而,由于对hERG的显著抑制,其至少比最小抑菌浓度高两个数量级,因此需要继续优化以发挥其全部潜力。

    by the design and synthesis of a new, amide-containing focused NBTI library to reduce hERG inhibition and maintain antibacterial activity against Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA). This optimization strategy yielded the lead compound 12 that exhibits potent antibacterial activity against Gram-positive bacteria, reduced hERG inhibition, no cardiotoxicity
    新型细菌拓扑异构酶抑制剂 (NBTI) 是用于治疗多重耐药细菌感染的新型有前途的抗菌剂。近年来,许多新的 NBTI 被发现,但它们中的大多数都在同一个问题上挣扎——抗菌活性和 hERG 相关毒性之间的平衡。我们通过优化之前的 NBTI 系列开始了一项新的活动,随后设计和合成了一个新的、含酰胺的重点 NBTI 文库,以减少 hERG 抑制并保持对革兰氏阳性菌(包括耐甲氧西林金黄色葡萄球菌)的抗菌活性(耐甲氧西林金黄色葡萄球菌)。这种优化策略产生了先导化合物12对革兰氏阳性菌表现出强大的抗菌活性,降低 hERG 抑制,在斑马鱼模型中没有心脏毒性,并且在 MRSA 感染的中性粒细胞减少小鼠大腿感染模型中具有良好的体内功效。
  • Exploring Alternative Pathways to Target Bacterial Type II Topoisomerases Using NBTI Antibacterials: Beyond Halogen-Bonding Interactions

    Novel bacterial topoisomerase inhibitors (NBTIs) are a new class of antibacterial agents that target bacterial type II topoisomerases (DNA gyrase and topoisomerase IV). Our recently disclosed crystal structure of an NBTI ligand in complex with DNA gyrase and DNA revealed that the halogen atom in the para position of the phenyl right hand side (RHS) moiety is able to establish strong symmetrical bifurcated halogen bonds with the enzyme; these are responsible for the excellent enzyme inhibitory potency and antibacterial activity of these NBTIs. To further assess the possibility of any alternative interactions (e.g., hydrogen-bonding and/or hydrophobic interactions), we introduced various non-halogen groups at the p-position of the phenyl RHS moiety. Considering the hydrophobic nature of amino acid residues delineating the NBTI’s binding pocket in bacterial topoisomerases, we demonstrated that designed NBTIs cannot establish any hydrogen-bonding interactions with the enzyme; hydrophobic interactions are feasible in all respects, while halogen-bonding interactions are apparently the most preferred.

    新型细菌拓扑异构酶抑制剂(NBTI)是一类新的抗菌剂,以细菌 II 型拓扑异构酶(DNA 回旋酶和拓扑异构酶 IV)为靶标。我们最近公布的 NBTI 配体与 DNA gyrase 和 DNA 复合物的晶体结构显示,位于苯基右侧 (RHS) 分子对位的卤原子能够与酶建立牢固的对称二叉卤素键;这是这些 NBTI 具有出色的酶抑制效力和抗菌活性的原因。为了进一步评估其他相互作用(如氢键和/或疏水相互作用)的可能性,我们在苯基 RHS 分子的 p 位引入了各种非卤素基团。考虑到细菌拓扑异构酶中划定 NBTI 结合袋的氨基酸残基的疏水性,我们证明设计的 NBTI 不能与酶建立任何氢键相互作用;疏水相互作用在所有方面都是可行的,而卤键相互作用显然是最可取的。

  • A Fine-Tuned Lipophilicity/Hydrophilicity Ratio Governs Antibacterial Potency and Selectivity of Bifurcated Halogen Bond-Forming NBTIs

    Herein, we report the design of a focused library of novel bacterial topoisomerase inhibitors (NBTIs) based on innovative mainly monocyclic right-hand side fragments active against DNA gyrase and Topo IV. They exhibit a very potent and wide range of antibacterial activity, even against some of the most concerning hard-to-treat pathogens for which new antibacterials are urgently needed, as reported by the WHO and CDC. NBTIs enzyme activity and whole cell potency seems to depend on the fine-tuned lipophilicity/hydrophilicity ratio that governs the permeability of those compounds through the bacterial membranes. Lipophilicity of NBTIs is apparently optimal for passing through the membrane of Gram-positive bacteria, but the higher, although not excessive lipophilicity and suitable hydrophilicity seems to determine the passage through Gram-negative bacterial membranes. However, due to the considerable hERG inhibition, which is still at least two orders of magnitude away from MICs, continued optimization is required to realize their full potential.
