Halogenated indoles eradicate bacterial persister cells and biofilms

The emergence of antibiotic resistance has necessitated new therapeutic approaches to combat recalcitrant bacterial infections. Persister cells, often found in biofilms, are metabolically dormant, and thus, are highly tolerant to all traditional antibiotics and represent a major drug resistance mechanism. In the present study, 36 diverse indole derivatives were investigated with the aim of identifying novel compounds that inhibit persisters and biofilm formation by Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus. 5-Iodoindole and other halogenated indoles, 4-fluoroindole, 7-chloroindole, and 7-bromoindole, eradicated persister formation by E. coli and S. aureus, and 5-iodoindole most potently inhibited biofilm formation by the two bacteria. Unlike other antibiotics, 5-iodoindole did not induce persister cell formation, and 5-iodoindole inhibited the production of the immune-evasive carotenoid staphyloxanthin in S. aureus; hence, 5-iodoindole diminished the production of virulence factors in this strain. These results demonstrate halogenated indoles are potentially useful for controlling bacterial antibiotic resistance.

Design, synthesis, and in vitro pharmacology of new radiolabeled gamma-hydroxybutyric acid analogues including photolabile analogues with irreversible binding to the high-affinity gamma-hydroxybutyric acid binding sites

gamma-Hydroxybutyric acid (GHB) is a psychotropic compound endogenous to the brain. Despite its potential physiological significance, the complete molecular mechanisms of action remain unexplained. To facilitate the isolation and identification of the high-affinity GHB binding site, we herein report the design and synthesis of the first 125I-labeled radioligands in the field, one of which contains a photoaffinity label which enables it to bind irreversibly to the high-affinity GHB binding sites.

3D tailored design as a bioremediation strategy for a lagoon in Matanza-Riachuelo basin

A native strain of the microalgae Chlorella vugaris was shown to be effective for the reduction of several chemical and microbial contaminants present in polluted streams from the Matanza-Riachuelo Basin (M-R, 1). The microalgae immobilization in calcium alginate beads protects the cells from the toxic effects of numerous substances and from extreme pH and temperatures, allowing better survival and greater efficiency in the production of biomass [2, 3]. However, cells trapped in the matrix are easy to be devoured by the fauna existent. Saladita Norte lagoon is part of M-R, this watercourse exhibits a wide range of contaminants levels along the year, mainly depending on the seasonal regime. At certain periods of the year, these levels usually exceed the limits established in international standards of water quality [4-6]. Similarly to that observed in other streams of M-R, several nitrogenated compounds, phosphorus, metals, and saprophytic and pathogenic bacteria are the main contaminants of Saladita Norte. In order to protect the alginate beads from the birds and fishes predation, a 3D-printed PLA (polylactic acid) device was designed. PLA is a biocompatible and biodegradable material that has been described as suitable for biotechnological applications. [7]. Bioprocesses carried out with this material must be checked for mechanical stability and optimal pore size to allow an effective bioremediation process. For this purpose, we used a stirredtank bioreactor supplied with a marine propeller and aeration during 6 days. Growth index and biomass production were compared between algae immobilized in alginate beads versus immobilized in alginate beads placed into a complex 3D printed PLA device. As previously observed, our native isolate of C. vulgaris could grow inside the alginate beads based on the consumption of several of the above-mentioned contaminants, such as phosphorus and nitrogenated ions [1]. The results obtained in control treatments with immobilized cells in alginate beads were: A- MS synthetic culture media supplemented with sucrose (3% w/v) and indolacetic acid (1 mg/L) as growth regulator [1] (mu=0.737, dt= 24 h) and B- as A- but growing in Saladita Norte water (mu=0.668, dt= 24 h). Also, treatments using 3D-device were: C- like B, but Chlorella cultures immobilized in alginate beads growing into a PLA3D scaffold coloured red (mu=0.341, dt= 2 d); D- like C, but coloured white (mu=0.206, dt= 3 d); and E- like C, but uncoloured (mu=0.342, dt= 2 d) were effective and successful to bioremediation in vitro. All cultures were kept at 24¡À2C, with a photoperiod of 16 h under PAR (above 400 mumol photon m-2 s-1). The data obtained were complemented with standardized cytotoxicity tests using Allium cepa and Lactuca sativa seeds. Germination rate and mitotic index of onion seeds and germination rate and length of lettuce seeds using polluted water or bioremediated water were compared. The results obtained demonstrate the potential of this technology to be used in integrated processes that seek removal of xenobiotics.

Discovery of VX-509 (Decernotinib): A Potent and Selective Janus Kinase 3 Inhibitor for the Treatment of Autoimmune Diseases

While several therapeutic options exist, the need for more effective, safe, and convenient treatment for a variety of autoimmune diseases persists. Targeting the Janus tyrosine kinases (JAKs), which play essential roles in cell signaling responses and can contribute to aberrant immune function associated with disease, has emerged as a novel and attractive approach for the development of new autoimmune disease therapies. We screened our compound library against JAK3, a key signaling kinase in immune cells, and identified multiple scaffolds showing good inhibitory activity for this kinase. A particular scaffold of interest, the 1H-pyrrolo[2,3-b]pyridine series (7-azaindoles), was selected for further optimization in part on the basis of binding affinity (Ki) as well as on the basis of cellular potency. Optimization of this chemical series led to the identification of VX-509 (decernotinib), a novel, potent, and selective JAK3 inhibitor, which demonstrates good efficacy in vivo in the rat host versus graft model (HvG). On the basis of these findings, it appears that VX-509 offers potential for the treatment of a variety of autoimmune diseases.

Synthesis and characterisation of polymerisable photochromic spiropyrans: towards photomechanical biomaterials

A methodology for the synthesis of novel polymerisable spiropyrans with photomechanical properties suitable for subsequent copolymerisation with either vinyl or acrylate-based biomaterials is described. UV-vis spectroscopic characterisation of photoisomerism shows that photochromic behaviour with respect to related non-polymerisable compounds is retained and is solvent dependent. In acetone, conventional spiropyran-merocyanine photochromism is observed for nitro-spiropyran derivatives, whereas in dichloromethane both nitro-spiropyrans and spiropyrans isomerise to merocyanines which rapidly form H-aggregates. The monomers were designed such that an alkyl spacer of variable length, both electronically and sterically, separates the polymerisable moiety from the photochromic core and allows steric aspects of the resulting photomechanical behaviour to be explored.
