Biofilms consist of a multicellular community of microorganisms adhered to a surface and encased within a self-produced extracellular matrix. Infections caused by bacteria residing within a biofilm exhibit elevated levels of resistance to both antibiotics and the host immune response, which makes treatment a significant challenge and places a considerable burden upon healthcare settings. One approach toward overcoming such infections centers on the development of therapeutic entities that inhibit biofilm formation. These inhibitors should render bacteria susceptible to conventional antibiotics and have the potential to be a valuable addition to our antibacterial armory as adjuvant therapies. A diverse range of biofilm inhibitors have been explored, both in terms of molecular structure and mechanism of biofilm inhibition. Examples presented in this chapter include small molecule inhibitors of bacterial signaling and communication pathways, such as quorum sensing inhibitors and two-component system inhibitors. The identification of natural products possessing anti-biofilm activity from plants and marine organisms is described, as is the use of antimicrobial peptides to inhibit biofilm formation. Finally, enzymatic approaches to the inhibition of biofilm formation include the development of quorum quenchers and degradation of the biofilm matrix by various DNases, proteases and glycosidases are discussed.

The steady growth of inflammatory diseases of the udder in dairy cattle forces us to look for the causes of this phenomenon in the context of growing chemical pollution of the environment and feeds. Within the framework of this concept, an analysis was made of the polarity level of the three toxic impurity groups, which are commonly present in dairy cattle feeds. These impurities are presented by mycotoxins, polyaromatic hydrocarbons (PAH) and persistent organic pollutants (POP). It has been determined that 46% of studied mycotoxins (n = 1500) and 100% of studied polyaromatic hydrocarbons (n = 45) and persistent organic pollutants (n = 55) are lipophilic compounds, prone to bioaccumulation. A comparative evaluation of the sorption capacity of four adsorbents of a different nature and polarity with respect to the simplest PAH, naphthalene and lipophilic estrogenic mycotoxin, zearalenone in vitro has been carried out. The highest efficiency in these experiments was demonstrated by the reversed-phase polyoctylated polysilicate hydrogel (POPSH). The use of POPSH in a herd of lactating cows significantly reduced the transfer of aldrin, dieldrin and heptachlor, typical POPs from the ?dirty dozen?, to the milk. The relevance of protecting the main functional systems of animals from the damaging effects of lipophilic toxins from feeds using non-polar adsorbents, and the concept of evaluating the effectiveness of various feed adsorbents for dairy cattle by their influence on the somatic cell count in the collected milk are discussed.

This methodology features a broad substrate scope and good functional group compatibility. The synthetic versatility of this protocol has been highlighted by the gram-scale synthesis and late-stage diversification of biologically active molecules.

Fusarium, a large genus of filamentous fungi, is widely distributed in soil and plants. Fusarium is a prolific source of novel chemical constituents with various bioactivities. In search for antibiotics from soil and endophytic fungi, the secondary metabolites of Fusarium avenaceum SF-1502 and Fusarium proliferatum AF-04 were investigated. An alkaloid (1), a depsipeptide (6), and five sesquiterpenoids (7-11) were isolated from the extracts of the soil fungus F. avenaceum SF-1502. Three alkaloids (2-4), a depsipeptide (5), three sesquiterpenoids (9, 11, and 12), a sesterterpene (13), and four 1,4-naphthoquinones (14-17) were also separated from the extract of the green Chinese onion derived fungus F. proliferatum AF-04.

Solvation of biomolecules and their building blocks has a strong influence on their structure and function. Herein we characterize the initial microsolvation of the 5-hydroxyindole cation (5HI+) in its 2A? ground electronic state with nonpolar and quadrupolar ligands (L = Ar, N2) by infrared photodissociation (IRPD) spectroscopy of cold and mass-selected 5HI+-Ln (n ? 3) clusters in a molecular beam and dispersion-corrected density functional theory calculations (B3LYP-D3/aug-cc-pVTZ). The isomer-selective OH and NH stretch frequency shifts (DeltanuOH/NH) disentangle the competition between H-bonding to the acidic OH and NH groups and pi-stacking to the conjugated bicyclic aromatic pi-electron system, the intermolecular interaction strengths, and the cluster growth sequence. For 5HI+-Arn, H-bonding and pi-stacking strongly compete, indicating that dispersion forces are important for the interaction of 5HI+ with nonpolar ligands. In contrast, for 5HI+-(N2)n clusters, the H-bonds are much stronger than the pi-bonds and largely determine the initial solvation process. In all clusters, the OH?L bonds are stronger than the NH?L bonds followed by the pi-bonds. The interaction of 5HI+ with N2 is roughly twice stronger than with Ar, mainly due to the additional quadrupole moment of N2. The nature and strength of the individual interactions are quantified by the noncovalent interaction approach. Comparison of 5HI+-L with the corresponding neutral clusters reveals the strong impact of ionization on the total and relative interaction strengths of the H-bonds and pi-bonds. In addition, comparison of 5HI+-L with corresponding clusters of the phenol, indole, and pyrrole radical cations illustrates the effects of substitution of functional groups and the addition of aromatic rings to the various subunits of 5HI on the intermolecular potential.
