Alcohol dehydrogenases (ADHs) together with the economical substrate-coupled cofactor regeneration system play a pivotal role in the asymmetric synthesis of chiral alcohols; however, severe challenges concerning the poor tolerance of enzymes to 2-propanol and the adverse effects of the by-product, acetone, limit its applications, causing this strategy to lapse. Herein, a novel ADH gene smadh2 was identified from Stenotrophomonas maltophilia by traditional genome mining technology. The gene was cloned into Escherichia coli cells and then expressed to yield SmADH2. SmADH2 has a broad substrate spectrum and exhibits excellent tolerance and superb activity to 2-propanol even at 10.5 M (80%, v/v) concentration. Moreover, a new thermostatic bubble column reactor (TBCR) system is successfully designed to alleviate the inhibition of the by-product acetone by gas flow and continuously supplement 2-propanol. The organic waste can be simultaneously recovered for the purpose of green synthesis. In the sustainable system, structurally diverse chiral alcohols are synthesised at a high substrate loading (>150 g L-1) without adding external coenzymes. Among these, about 780 g L-1 (6 M) ethyl acetoacetate is completely converted into ethyl (R)-3-hydroxybutyrate in only 2.5 h with 99.9% ee and 7488 g L-1 d(-1) space-time yield. Molecular dynamics simulation results shed light on the high catalytic activity toward the substrate. Therefore, the high 2-propanol tolerance SmADH2 with the TBCR system proves to be a potent biocatalytic strategy for the synthesis of chiral alcohols on an industrial scale.

A brick pavement, tramped by humans, is exposed to atmospheric elements, thus allowing cyanobacteria and algae to colonise. In this article, we report on the factors that contribute to the slipperiness of a brick pavement at the University of Venda in the Limpopo province of the South Africa. Samples were collected from brick surfaces either colonised by green algae (treated) or not (control). The samples were acid-digested and analysed for metals by Inductively Coupled Plasma Mass Spectrometry (ICP MS) in parts per billion (ppb). The treated bricks, with green algae, had average high metal contents (ppb): Al 9456.02, Ti 731.23, V 46.44, Cr 78.85, Mn 862.93, Fe 16295.18, Co 23.57, Ni 59.36, Cu 66.31, Zn 160.57, As 7.92, Se 10.45, Mo 6.74, Cd 5.19, Sn 4.65, Sb 2.31 and Pb 19.51. In contrast, control bricks had a low average of metal content (ppb) as follows: Al 2.99, Ti 0.28, V 4.04, Cr 1.42, Mn 4.29, Fe 20.89, Co 0.36, Ni 2.74, Cu 5.64, Zn 4.21, As 0.56, Se <3.00, Mo 0.88, Cd 0.01, Sn 1.05, Sb 0.04 and Pb 0.04. Other factors that promote algae colonisation include high solar radiation, neutral pH, nutrients, low electrical conductivity and total dissolved solids. The algae colonisation of brick pavement results in an unaesthetic sighting and a slippery surface that is hazardous to humans. Category: benzodioxans.

In the present work, four types of heterocyclic core-based polybenzoxazine matrices (HC-PBZ) developed based on pyridine, thiophene, and thiazole and their molecular structure, thermal, flame-retardant and luminescent properties were studied and discussed. The heterocyclic core-based benzoxazine monomers (HC-BZ) were synthesized using two types of phenols (phenol, and 4-hydroxyphenylacetonitrile), and two types of heterocyclic diamines [2,6-Bis-(4-aminophenyl)-4-thiophen-2-yl-pyridine (BATP) and 4-(2-methylthiazol-5-yl)-2,6-bis-(4-aminophenyl)-pyridine (BAMTP)] with formaldehyde through Mannich reaction. The structure of the four HC-BZ monomers was confirmed by various spectral analysis such as Fourier-transform infrared spectroscopy (FTIR), and Nuclear magnetic resonance spectroscopy ((HNMR)-H-1 and (CNMR)-C-13). All the four HC-BZ monomers have the maximum range of curing temperature (T-p) between 252 and 267 degrees C. Data resulted from the thermal studies indicate that the HC-PBZ exhibits better T-g,T- thermal stability and flame-retardant properties. Among the four HC-PBZ systems the thiazole based system possesses the higher value of T-g of 268 degrees C and thermal stability when compared to those of other matrices. It was also observed that the HC-BZ monomers and HC-PBZ polymers exhibit a photoluminescent (PL) emission range between 441-445 and 414-417nm, respectively. Overall, it seems that the thiazole and thiophene based HC-PBZ can be considered as competitive materials for luminescent applications with high thermal and flame-retardant properties.

The West Nile Virus (WNV) NS2B-NS3 protease is an attractive target for the development of therapeutics against this arboviral pathogen. In the present investigation, the screening of a small library of fifty-eight synthetic compounds against the NS2-NB3 protease of WNV is described. The following groups of compounds were evaluated: 3-(2-aryl-2-oxoethyl)isobenzofuran-1(3H)-ones; eugenol derivatives bearing 1,2,3-triazolic functionalities; and indan-1,3-diones with 1,2,3-triazolic functionalities. The most promising of these was a eugenol derivative, namely 4-(3-(4-allyl-2-methoxyphenoxy)-propyl)-1-(2-bromobenzyl)-1H-1,2,3-triazole (35), which inhibited the protease with IC50 of 6.86 mu mol L-1. Enzyme kinetic assays showed that this derivative of eugenol presents competitive inhibition behaviour. Molecular docking calculations predicted a recognition pattern involving the residues His(51) and Ser(135), which are members of the catalytic triad of the WNV NS2B-NS3 protease.

Application In Synthesis of 1-(4-Nitrophenyl)ethanone. Shtukenberg, AG; Zhu, XL; Yang, YF; Kahr, B in [Shtukenberg, Alexander G.; Zhu, Xiaolong; Yang, Yongfan; Kahr, Bart] NYU, Dept Chem, New York, NY 10003 USA; [Shtukenberg, Alexander G.; Zhu, Xiaolong; Yang, Yongfan; Kahr, Bart] NYU, Mol Design Inst, New York, NY 10003 USA published Common Occurrence of Twisted Molecular Crystal Morphologies from the Melt in 2020, Cited 49. The Name is 1-(4-Nitrophenyl)ethanone. Through research, I have a further understanding and discovery of 100-19-6.

Two books that describe the forms of thin films of many molecular crystals grown from the melt in polarized light, Gedrillte Kristalle (1929) by Ferdinand Bernauer and Thermomicroscopy in the Analysis of Pharmaceuticals (1971) by Maria Kuhnert-Brandstatter, are analyzed. Their descriptions, especially of curious morphologies consistent with helicoidal twisting of crystalline fibrils or narrow lamellae, are compared in the aggregate with observations from our laboratory collected during the past 10 years. According to Bernauer, 27% of molecular crystals from the melt adopt helicoidal crystal forms under some growth conditions even though helicoids are not compatible with long-range translational symmetry, a feature that is commonly thought to be an a priori condition for crystallinity. Bernauer’s figure of 27% is often met with surprise if not outright skepticism. Kuhnert-Brandstatter was aware of the tell-tale polarimetric signature of twisting (rhythmic interference colors) but observed this characteristic morphology in less than 0.5% of the crystals described. Here, the experience of the authors with 101 arbitrarily selected compounds-many of which are polymorphous-representing 155 total crystal structures, shows an even higher percentage (ca. 31%) of twisted crystals than the value reported by Bernauer. These observations, both positive (twisting) and negative (no twisting), are tabulated. It is concluded that twisting is not associated with molecular structure or crystal structure/symmetry. Rather, these nonclassical morphologies are associated with certain habits with exaggerated aspect ratios, and their appearance is strongly controlled by the growth conditions. Comments are offered in an attempt to reconcile the observations here, and those of Bernauer, the work of seekers of twisted crystals, with those of Kuhnert-Brandstatter, whose foremost consideration was the characterization of polymorphs of compounds of medicinal interest.

The highly diastereoselective synthesis of perfluoroalkyl-containing pyrano[3,4-c]pyrroles has been accomplished via a cascade process involving Michael addition, Passerini-type reaction, Mumm rearrangement and an oxo-Diels-Alder reaction. This domino transformation of isocyanides, methyl perfluoroalk-2-ynoates and 3-aroyl (or heteroyl) acrylic acids proceeded smoothly at room temperature and led to the formation of the highly diastereoselective target compounds with high functional-group compatibility in good to excellent yields.
