Abstract
Butenolides are a class of 5-membered lactones that hold great potential as bio-based monomers to replace oil-derived acrylates, of which they are cyclic analogues. Despite this structural resemblance, the reactivity of the unsaturated ester moiety of electron-poor butenolides leans toward that of maleic anhydride, another essential monomer that does not homopolymerize but copolymerizes in a highly alternating fashion with polarized electron-rich comonomers. By studying the reactivity of 5-methoxy and 5-acyloxy butenolides through a combination of kinetics and density functional theory (DFT) experiments, we explain why electron-poor butenolides constitute a missing link between acrylates and maleic anhydride in radical polymerization.

Unraveling the Molecular Mechanism of Selective Antimicrobial Activity of 2(5 H)-Furanone Derivative against Staphylococcus aureus. Int J Mol Sci 2019; 20:ijms20030694. [PMID: 30736278 PMCID: PMC6387044 DOI: 10.3390/ijms20030694] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2018] [Revised: 01/29/2019] [Accepted: 02/03/2019] [Indexed: 11/16/2022] Open
Abstract
Staphylococcus aureus causes various infectious diseases, from skin impetigo to life-threatening bacteremia and sepsis, thus appearing an important target for antimicrobial therapeutics. In turn, the rapid development of antibiotic resistance and biofilm formation makes it extremely robust against treatment. Here, we unravel the molecular mechanism of the antimicrobial activity of the recently unveiled F105 consisting of three pharmacophores: chlorinated 2(5H)-furanone, sulfone, and l-menthol moieties. F105 demonstrates highly selective activity against Gram-positive bacteria and biofilm-embedded S. aureus and exhibits low risk of resistance development. We show explicitly that the fluorescent analogue of F105 rapidly penetrates into Gram-positive bacteria independently of their cell integrity and viability and accumulates there. By contrast, Gram-negative bacteria remain impermeable and, therefore, insusceptible to F105. Apparently, in bacterial cells, F105 induces reactive oxygen species (ROS) formation and nonspecifically interacts with a number of proteins, including ROS-utilizing ones. Using native and 2D PAGE, we confirm that F105 changes the charge of some proteins by either oxidation or direct interaction with them. Therefore, it seems justified to conclude that being simultaneously a ROS inducer and damaging proteins responsible for ROS utilization, F105 impairs the cellular anti-ROS defense representing a prospective ROS-inducing antibacterial agent.

Abstract
A series of 2(5H)-furanone-based compounds were synthesized from commercially available mucohalic acids. From the first-generation compounds, three showed inhibitory activity (10 µg/mL) of at least 35% against Mycobacterium smegmatis mc(2) 155 growth (Bioscreen C system). In screening the active first-generation compounds for growth inhibition against Mycobacterium tuberculosis H37Rv, the most active compound was identified with a minimum inhibitory concentration (MIC99 ) of 8.07 µg/mL (15.8 µM) using BACTEC 460 system. No cross-resistance was observed with some current first-line anti-TB drugs, since it similarly inhibited the growth of multidrug resistant (MDR) clinical isolates. The compound showed a good selectivity for mycobacteria since it did not inhibit the growth of selected Gram-positive and Gram-negative bacteria. It also showed synergistic activity with rifampicin (RIF) and additive activity with isoniazid (INH) and ethambutol (EMB). Additional time-kill studies showed that the compound is bacteriostatic to mycobacteria, but cytotoxic to the Chinese Hamster Ovarian (CHO) cell line. From a second generation library, two compounds showed improved anti-TB activity against M. tuberculosis H37Rv and decreased CHO cell cytotoxicity. The compounds exhibited MIC values of 2.62 µg/mL (5.6 µM) and 3.07 µg/mL (5.6 µM) respectively. The improved cytotoxicity against CHO cell line of the two compounds ranged from IC50 = 38.24 µg/mL to IC50 = 45.58 µg/mL when compared to the most active first-generation compound (IC50 = 1.82 µg/mL). The two second generation leads with selectivity indices (SI) of 14.64 and 14.85 respectively, warrant further development as anti-TB drug candidates. © 2016 IUBMB Life, 68(8):612-620, 2016.

Abstract
Hydroxyhalofuranones form a group of genotoxic disinfection byproduct (DBP) of increasing interest. Among them, mucohalic acids (3,4-dihalo-5-hydroxyfuran-2(5H)-one, MXA) are known mutagens that react with nucleotides, affording etheno, oxaloetheno, and halopropenal derivatives. Mucohalic acids have also found use in organic synthesis due to their high functionalization. In this work, the alkylation kinetics of mucochloric and mucobromic acids with model nucleophiles aniline and NBP has been studied experimentally. Also, the alkylation mechanism of nucleosides by MXA has been studied in silico. The results described allow us to reach the following conclusions: (i) based on the kinetic and computational evidence obtained, a reaction mechanism was proposed, in which MXA react directly with amino groups in nucleotides, preferentially attacking the exocyclic amino groups over the endocyclic aromatic nitrogen atoms; (ii) the suggested mechanism is in agreement with both the product distribution observed experimentally and the mutational pattern of MXA; (iii) the limiting step in the alkylation reaction is addition to the carbonyl group, subsequent steps occurring rapidly; and (iv) mucoxyhalic acids, the hydrolysis products of MXA, play no role in the alkylation reaction by MXA.

Abstract
New monohalogenated maleimide derivatives (with bromine, chlorine or iodine) were synthesized to test the effect of halogen atoms in inhibiting the formation of Pseudomonas aeruginosa biofilm. The evaluation of their biological activities clearly defines a structure-activity relationship. In this study, the bactericidal action of the three compounds was observed at the concentration range 0.3-5.0 mM on Luria-Bertani agar plates. The halogen atom of these molecules was critical in modulating the antibacterial activity, with a slightly higher effectiveness for chlorine. Confocal laser scanning microscopy was used to examine P. aeruginosa biofilms cultivated in flow cells. At concentration as low as 40 microM, the bromine and iodine compounds displayed a total inhibition towards the formation of bacterial biofilm. At this concentration, the bacterial attachment to glass surfaces was strongly affected by the presence of bromine and iodine whereas the chlorine derivative behaved as a bactericidal compound. A bioluminescent reporter strain was then used to detect the effect of the chemically synthesized maleimides on quorum sensing (QS) in P. aeruginosa. At the concentration range 10-100 microM, bioluminescence assays reveal that halogenated maleimides were able to interfere with the QS of the bacterium. Although the relationship between the weak inhibition of cell-to-cell communication (15-55% of the signal) and the high inhibition of biofilm formation has not been elucidated clearly, the results demonstrate that bromo- and iodo-N-substituted maleimides bromine and iodine may be used as new potent inhibitors that control bacterial biofilms.
