Covering: Up to end of June 2018 Baeyer-Villiger monooxygenases (BVMOs) are flavin-dependent enzymes that catalyse the oxidation of ketones and cyclic ketones to esters and lactones, respectively, by using molecular oxygen and NAD(P)H. BVMOs also catalyse sulfoxidations and N-oxidations. BVMOs are widely studied as attractive biocatalysts, but also catalyse key reactions in metabolic pathways of the organisms from which they are sourced. BVMOs are involved in the primary metabolism of atypical carbon sources, thereby conferring an evolutionary advantage to the host organism. In addition, BVMOs catalyse a plethora of diverse Baeyer-Villiger and heteroatom oxidations in the construction of complex secondary metabolites. These natural products often have attractive biological properties, such as anti-bacterial, anti-cancer and anti-proliferative activity, and can have clinical applications. In contrast, BVMOs are also involved in the synthesis of microbial toxins. This review will discuss the inherent roles of type I, type II and type O BVMOs in the metabolism of microorganisms.

Antibiotic resistance is a significant emerging health threat. Exacerbating this problem is the overprescription of antibiotics as well as a lack of development of new antibacterial agents. A paradigm shift toward the development of nonantibiotic agents that target the virulence factors of bacterial pathogens is one way to begin to address the issue of resistance. Of particular interest are compounds targeting bacterial AB toxins that have the potential to protect against toxin-induced pathology without harming healthy commensal microbial flora. Development of successful antitoxin agents would likely decrease the use of antibiotics, thereby reducing selective pressure that leads to antibiotic resistance mutations. In addition, antitoxin agents are not only promising for therapeutic applications, but also can be used as tools for the continued study of bacterial pathogenesis. In this review, we discuss the growing number of examples of chemical entities designed to target exotoxin virulence factors from important human bacterial pathogens.

Seven crystalline molecular complexes were formed between perfumes such as guaiacol, 2-methylindole, and skatole and cationic surfactants such as hexadecyl-, tetradecyl-, dodecyl-, and decyltrimethylammonium bromide from an aqueous or methanol solution at low temperatures (< 10 C). The crystal structures were determined by X-rays. The structures are very similar to each other, that is, the perfume molecules are packed in the layers of the alkyl chains of the surfactant molecules. Those packings are substantially the same as the common packing pattern observed in complexes between the surfactants and the aromatic compounds. The thermal analysis showed that the volatilization temperatures of the perfumes increased significantly when the perfumes are packed in the complex crystals. Moreover, the molar loss ratio of the perfume with increasing the temperature decreased with increasing the length of the alkyl chain of the surfactant. This suggests that thermal stability of the perfumes can be controlled by forming the complexes with the surfactants containing different alkyl chains.

(Chemical Equation Presented) A new and efficient synthetic route to chiral 3-substituted hexahydropyrroloindoline 18 possessing absolute configurations in accordance with indole alkaloids has been developed from readily available L-tryptophan. The key step relies on the one-pot cascade reaction of oxazolidinone 17 with diazoester, which proceeds through intermolecular cyclopropanation, ring opening, and cyclization.

Measurements of the surface tension of aqueous solutions of Triton X-100, Triton X-114, Triton X-165, sodium dodecylsulfate, sodium hexadecylsulfonate, cetyltrimethylammonium bromide, cetylpyridinium bromide, sodium N-lauryl sarcosinate, dodecyldimethylethylammonium bromide, tetradecyltrimethylammonium bromide and benzyldimethyldodecylammonium bromide were made at different temperatures. On the basis of the obtained results the activity of the surfactants at the water-air interface was determined and discussed based on the intermolecular interactions. The surfactant activity at the water-air interface was taken into account for determination of thermodynamic parameters of surfactant adsorption using the Langmuir method and the Szyszkowski equation. The thermodynamic parameters were also determined by means of the Rosen and Aronson, Gamboa and Olea methods as well that based on the changes of tail-water interface tension to that of tail-air.

The synthesis of an optically active hemiporphyrazine with chiral binaphthyl substituents (1) is reported, providing the first example of the incorporation of an intrinsically chiral moiety into the macrocyclic core of a hemiporphyrazine analogue. A negative circular dichroism (CD) signal is observed in the 325?450 nm region of the CD spectrum of (S,S)-1, while mainly positive bands are observed in the 220?325 nm region. Mirror symmetry is observed across the entire wavelength range of the CD spectra of (R,R)-1 and (S,S)-1. An irreversible one-electron oxidation wave with an onset potential at 1.07 V is observed by cyclic voltammetry, along with a reversible one-electron reduction wave at ?0.85 V. Density functional calculations reproduce the experimentally observed data and trends, and provide further insight into the nature of the electronic transitions.

In this article, we describe the synthesis of imprinted chiral silica nanotubes based on the use of a chiral N-stearoyl l-serine (C18Ser) anionic surfactant as the chiral template. The resulting chiral silica nanotube structures were characterized by electronic microscopy (transmission electron microscopy (TEM) and scanning electron microscopy (SEM)) and nitrogen isotherms that proved the formation of well-ordered silica nanotubes. A C18Ser surfactant template was used for the preparation of the silica nanotubes, due to its effective molecular organization within the silica network. After chemical extraction of the chiral template, the enantioselectivity feature of the silica nanotubes was confirmed by selective adsorption of the enantiomers using circular dichroism (CD) and isothermal titration calorimetry (ITC) measurements. Although these measurements show a relatively low chiral selectivity of the silica nanotubes (ca. 6% enantiomeric excess), the system described here offers new approaches for the application of chiral porous materials in chirality.

Four unsymmetrical oxovanadium phenanthroimidazole complexes, [VO(hntdtsc)(NPIP)] (1), [VO(hntdtsc)(CPIP)] (2), [VO(hntdtsc)(MEPIP)] (3) and [VO(hntdtsc)(HPIP)] (4) (hntdtsc = 2-hydroxy-1-naphthaldehyde thiosemicarbazone, NPIP = 2-(4-nitrophenyl)-imidazo[4,5-f]1,10-phenanthroline, CPIP = 2-(4-chlorphenyl)-imidazo[4,5-f]1,10-phenanthroline), MEPIP = 2-(4-methylphenyl)-imidazo[4,5-f]1,10-phenanthroline), HPIP = 2-(4-hydroxylphenyl)-imidazo[4,5-f] 1,10-phenanthroline), have been synthesized and characterized. Their DNA binding and antitumor activities were determined by biochemical methods. All four oxovanadium complexes can bind with CT-DNA by an intercalation model and can also cleave supercoiled plasmid DNA in the presence of H2O2. The antitumor properties and mechanism of the complexes have been analyzed by MTT assay, cell cycle analysis, apoptosis assay and Western blot analysis. The results showed that the free ligands and their corresponding complexes all possess antiproliferative activities with very low IC50 values against Hela, BIU-87 and SPC-A-1 cell lines. Complex 1, which has a strongly electron-withdrawing nitro group, exhibited the best antiproliferative activities. Complex 1 caused G0/G1 phase arrest of the cell cycle and induced apoptosis in Hela cells. Additionally, complex 1 attenuated the phosphorylation of extracellular signal-regulated kinases 1 and 2 (ERK1/2).This indicates that inhibition of the ERK1/2 signaling pathway may contribute to the antitumor effects of these complexes.
