  • 4-Hydroxy-2-pyridone Derivatives and the δ-pyrone Isostere as Novel Agents Against Mycobacterium smegmatis Biofilm Inhibitors
    作者:Maheshkumar R. Borkar、Santosh Nandan、Harish K.M. Nagaraj、Jayashree Puttur、Jisha Manniyodath、Dipankar Chatterji、Evans C. Coutinho
    DOI:10.2174/1573406414666180525075755
    日期:2019.1.7
    Background:

    The treatment of a bacterial infection when the bacterium is growing in a biofilm is a vexed issue. This is because the bacteria in a biofilm behaves differently compared to the individual planktonic free-form. As a result, traditional antibacterial agents lose their activity.

    Objective:

    Presently, there are not many drugs that are effective against bacteria growing in biofilms. Based on literature reports, we have sought to develop novel derivatives of 4-hydroxy-2- pyridone as both antimycobacterial and antibiofilm agents. </P><P> Methods: The pyridone derivatives were synthesized by reacting 4-hydroxy-6-methyl-2H-pyran-2- one with appropriate amines and followed by reaction with substituted phenyl isocyanates as reported in the literature.

    Results:

    Four compounds in this series significantly inhibit the growth and formation of biofilm by Mycobacterium smegmatis (mc2 155 strain) at 50 µg/ml. Further, in silico evaluation of the ADME parameters shows that these compounds possess good drug-like properties and have the potential to be developed both as antibiofilm and as oral antimycobacterial agents.

    Conclusion:

    This finding is of significance as presently very few small molecules are known to inhibit biofilm formation in mycobacteria. These compounds are unique in the sense that they are more potent against Mycobacterium smegmatis in the biofilm state compared to the planktonic form.

    背景:当细菌生长在生物膜中时治疗细菌感染是一个棘手的问题。这是因为生物膜中的细菌行为与单个游离状态的浮游细菌不同。因此,传统抗菌剂失去了活性。 目标:目前,没有太多药物对生长在生物膜中的细菌有效。根据文献报道,我们试图开发4-羟基-2-吡啶酮的新衍生物,作为抗结核菌和抗生物膜剂。 方法:通过将4-羟基-6-甲基-2H-吡喃-2-酮与适当的胺反应,并随后与文献报道的取代苯异氰酸酯反应,合成了吡啶酮衍生物。 结果:该系列中的四种化合物在50微克/毫升时显著抑制了沙眼支原体(mc2 155株)的生长和生物膜形成。此外,对这些化合物进行体外评估显示,这些化合物具有良好的药物样性质,并有潜力作为抗生物膜和口服抗结核菌剂开发。 结论:这一发现具有重要意义,因为目前很少有小分子被认为可以抑制结核菌的生物膜形成。这些化合物在对付生物膜状态下的沙眼支原体方面比浮游状态更有效。

    N-Substituted 6-methyl-1,2,3,4-tetrahydropyridine-2,4-diones reacted with aliphatic carboxylic acid chlorides in the presence of pyridine or triethylamine to give the corresponding 4-O-acyl derivatives which underwent O,C-migration of the acyl group by the action of 2 equiv of triethylamine and a catalytic amount of 2-hydroxy-2-methylpropanenitrile. Reactions of 3-acyl-6-methyl-1,2,3,4-tetrahydropyridine-2,4-diones thus formed with aliphatic and aromatic amines gave the corresponding enamino derivatives at the side acyl group. Enamino derivatives at the C4 =O group were obtained by transformation of 3-acyl-1,2,3,4-tetrahydropyridine-2,4-diones into 3-acyl-4-methoxy-6-methyl-1,2-dihydropyridin-2-ones via alkylation with dimethyl sulfate and subsequent treatment with amines.
