Mechanochemical Fluorescence Switching in Polymers Containing Dithiomaleimide Moieties

Polymers that display useful mechanochemical responses, such as changes of their fluorescence characteristics, are attracting great interest. Here, we introduce the fluorescent dithiomaleimide (DTM) motif as a mechanofluorophore and report the mechanoresponse of two polymer types containing this motif. Poly(methyl acrylate) (PMA) and poly(?-caprolactone)s (PCL) featuring one DTM moiety in the center of each chain (PMA-DTM and PCL-DTM) were synthesized by controlled radical and coordination-insertion ring-opening polymerizations using bifunctional DTM-containing initiators. Upon ultrasonic treatment of PMA-DTM or PCL-DTM of sufficiently high initial molecular weight, both the molecular weight and the fluorescence intensity decreased with similar kinetics, while no significant fluorescence changes were observed for DTM-free reference polymers. The results show that the DTM motif can serve as a mechanophore that displays a mechanically induced fluorescence turn-off.

In vitro characterization and stability profiles of antibody?fluorophore conjugates derived from interchain cysteine cross-linking or lysine bioconjugation

Fluorescent labelling of monoclonal antibodies (mAbs) is classically performed by chemical bioconjugation methods. The most frequent labelling technique to generate antibody-fluorophore conjugates (AFCs) involves the bioconjugation onto the mAb lysines of a dye bearing an N-hydroxysuccinimide ester or an isothiocyanate group. However, discrepancies between labelling experiments or kits can be observed, related to reproducibility issues, alteration of antigen binding, or mAb properties. The lack of information on labelling kits and the incomplete characterization of the obtained labelled mAbs largely contribute to these issues. In this work, we generated eight AFCs through either lysine or interchain cysteine cross-linking bioconjugation of green-emitting fluorophores (fluorescein or BODIPY) onto either trastuzumab or rituximab. This strategy allowed us to study the influence of fluorophore solubility, bioconjugation technology, and antibody nature on two known labelling procedures. The structures of these AFCs were thoroughly analyzed by mass spectroscopy, and their antigen binding properties were studied. We then compared these AFCs in vitro by studying their respective spectral properties and stabilities. The shelf stability profiles and sensibility to pH variation of these AFCs prove to be dye-, antibody- and labelling-technology-dependent. Fluorescence emission in AFCs was higher when lysine labelling was used, but cross-linked AFCs were revealed to be more stable. This must be taken into account for the design of any biological study involving antibody labelling.

Selectivity control by chemical modification of the recognition sites in two-point binding molecularly imprinted polymer

We demonstrated the possibility of modifying the selectivity of a two-point binding imprinted polymer by chemical modification of the binding sites inside the cavities. We used a thermally reversible bond for the preparation of the monomer-template complex, which allowed us to remove the template easily by means of a simple thermal reaction and to simultaneously introduce various functional groups into the cavity. A phenylmaleimide having an azidocarbonyl group was reacted with diethylstilbestrol (DES, template) to yield a monomer, where the template was linked to two polymerizable maleimido groups via a thermally reversible urethane bond. The polymerization of the monomer was carried out in the presence of ethylene glycol dimethacrylate (EGDMA) by the initiation with 2,2-azobis(isobutyronitrile) (AIBN) at 54C in DMF. The polymers were refluxed in 1,4-dioxane in the presence of a nucleophile such as water, methanol, or aniline. In this extraction step, the template molecules were removed from the polymer matrix, and simultaneously the isocyanato groups, which were generated by the thermal cleavage of the urethane bond, were converted to amino, urethane, or urea groups through their reaction with water, methanol, or aniline, respectively. The specific recognition ability of the imprinted polymers for the template and its structural analogues was dependent on the space between the two binding points as well as on the nature of the functional group. This method is especially propitious for developing artificial receptors for molecules lacking strongly interactive groups.

Marine bacteria as source of antimicrobial compounds

The marine environment encompasses a huge biological diversity and can be considered as an underexplored location for prospecting bioactive molecules. In this review, the current state of art about antimicrobial molecules from marine bacteria has been summarized considering the main phylum and sources evolved in a marine environment. Considering the last two decades, we have found as most studied group of bacteria producers of substances with antimicrobial activity is the Firmicutes phylum, in particular strains of the Bacillus genus. The reason for that can be attributed to the difficult cultivation of typical Actinobacteria from a marine sediment, whose members are the major producers of antimicrobial substances in land environments. However, a reversed trend has been observed in recent years with an increasing number of reports settling on Actinobacteria. Great diversity of chemical structures have been identified, such as fijimicyns and lynamicyns from Actinomycetes and macrolactins produced by Bacillus.
