Development of an Amine Transaminase-Lipase Cascade for Chiral Amide Synthesis under Flow Conditions

<p>The use of multienzymatic systems has gained increasing attention as a method of choice for complex (asymmetric) syntheses. Incompatibilities between substrates, reagents and/or enzymes in one-pot batch conditions can hamper the applicability of a pursued cascade, so the use of flow systems provide useful synthetic solutions. The implementation of immobilised enzymes in continuous flow reactors allows the compartmentalisation and segregation of the enzymes in separate reactors, leading to otherwise disfavoured reaction cascades. Here, an amine transaminase and a lipase have been immobilised on polymer-coated controlled porosity glass carrier materials and studied for the first time together in the transamination of a prochiral ketone followed by acylation of the corresponding chiral amine in flow mode, two incompatible transformations under batch. Thus, the preparation of (<em>R</em>)-<em>N</em>-(1-phenoxypropan-2-yl)acetamide was accomplished after optimisation of the reaction conditions.</p>

Research data: Continuity Amid Transformation: An Analysis of Pottery Production from the Late La Tène to Early Roman Periods in Eastern Bohemia

<p>Data used in the research presented in the article titled "Continuity Amid Transformation: An Analysis of Pottery Production from the Late La T&egrave;ne to Early Roman Periods in Eastern Bohemia".</p> <p><strong>Abstract of the article:</strong></p> <p>At the end of the La T&egrave;ne period and the beginning of the Roman period in the first century BC, society in Central Europe underwent a significant transformation, which included notable changes in pottery production. This transformation is often attributed to the collapse of the social structures of the La T&egrave;ne period and the arrival of a new population. Pottery production, in particular, is generally considered to have undergone a complete transformation.</p> <p>However, previous studies on this transition have primarily focused on the stylistic analysis of shapes and decorations, as illustrated by the pottery assemblage from Slepotice (Eastern Bohemia). In order to obtain additional data on the transitional period, this study of pottery from Slepotice incorporates analyses of the materials used and the manufacturing process through macroscopic observation, X-ray fluorescence analysis, and thin-section analysis. These analyses provide new insights into the differences in pottery production and distribution during the first century BC.</p> <p>Our research indicates that while the transformation included the collapse of the La T&egrave;ne socioeconomic network, it did not result in a complete break in the pottery production process.</p> <p>Link to the article: <a href="https://doi.org/10.1016/j.jasrep.2025.105073">https://doi.org/10.1016/j.jasrep.2025.105073</a></p> <p>&nbsp;</p> <p><strong>List of the files:</strong></p> <p>Supplementary Material 1<br>Settlement structure in the vicinity of Slepotice during the La T&egrave;ne and Roman periods: 1 &ndash; Slepotice, 2 &ndash; Česk&eacute; Lhotice, 3 &ndash; Brčekoly, 4 &ndash; Chrudim</p> <p>Supplementary Material 2<br>Values of pottery attributes (Mat, InMn, InVar, In, traces left from the shaping process, Po, Vy, and morphological groups) classified based on macroscopic observation</p> <p>Supplementary material 3<br>Schematic classification of rim attributes, illustrating different variants of rim direction (Op), thickening of the upper part of the rim (Oz), and trimming of the lip (Os)</p> <p>Supplementary material 4<br>Attributes of the 30 samples selected for XRF analysis based on macroscopic observation.

Impedance-based forecasting of battery performance amid uneven usage

<p>Dataset of 88 commercial lithium-ion coin cells cycled under multistage constant current charging/discharging, with currents randomly changed between cycles to emulate realistic use patterns.</p> <p>raw-data.zip contains the following data:</p> <p>Variable Discharge: We subject&nbsp;24 Powerstream LiR2032 coin cells (of nominal capacity 1C = 35mAh) to a sequence of randomly selected charge and discharge currents at room temperature for 110-120 full charge/discharge cycles. Each cycle consists of acquisition of the galvanostatic EIS spectrum, followed by a charging and discharging stage. We collect impedance measurements at 57 frequencies uniformly distributed in the log domain in the range 0.02Hz-20kHz. Charging consists of a two stage Constant Current (CC) protocol; currents are randomly selected in the ranges 70mA-140mA (2C-4C) and 35mA-105mA (1C-3C) in stages 1 and 2 respectively. If the safety threshold voltage of 4.3V is reached before the time limit then charging is stopped. During discharging, a single constant discharge current, randomly selected in the range 35mA-140mA (1C-4C), is applied, until the voltage drops to 3.0V.</p> <p>Fixed Discharge:&nbsp;We subject an additional 16&nbsp;Powerstream LiR2032 coin cells (of nominal capacity 1C = 35mAh) to the same cycling conditions as above, except&nbsp;now fixing the discharge current for all cells and cycles at 52.5mA (1.5C) instead of randomly changing the&nbsp;discharge current at each cycle.</p> <p>chemistry2-25C.zip contains the following data:</p> <p>Variable Discharge @ 25C: We subject&nbsp;32 RS-Pro&nbsp;LiR2032 coin cells (of nominal capacity 1C = 40mAh) to a sequence of randomly selected charge and discharge currents at room temperature for 110-120 full charge/discharge cycles.

Plant–insect interactions from the mid-Cretaceous at Puy-Puy (Aquitaine Basin, western France) indicates preferential herbivory for angiosperms amid a forest of ferns, gymnosperms, and angiosperms

<p>The nine in-text figures and table below (Appendices S1&ndash;S10), and the additional text and excel files attached, provide the raw data, summaries of the raw data, rarefaction analyses, and nonmetric multidimensional scale analyses (NMDS) that support the discussions of the main text. The raw data and their summaries of provide for each plant species or morphotype values important for assessment of their herbivory: percentage of specimens herbivorized, damage type (DT) richness, DT frequency, DT host-plant specificity, herbivorized surface area as a proportion of total surface area, and feeding event occurrences. The rarefaction analyses furnished evaluations of whether the number of samples was sufficient, given the surface area covered by those samples. For comparison, the number of samples was rarified to the number of DTs in those samples. Lastly, two NMDS analyses produced the relationships between the plant orders present in the plant assemblage and their interactive functional feeding groups (FFGs). A separate NMDS analysis shows the association between the three most herbivorized species and their FFGs.</p>

A human gut Faecalibacterium prausnitzii fatty acid amide hydrolase- Genome Annotation

<p>Genome annotation for <em>F. prausnitzii </em>Bg7063</p> <p><em>Science&nbsp;</em><strong>386</strong>, eado6828 (2024)</p> <p>DOI: 10.1126/science.ado6828</p> <p>Undernutrition in Bangladeshi children is associated with disruption of postnatal gut microbiota assembly; compared with standard therapy, a microbiota-directed complementary food (MDCF) substantially improved their ponderal and linear growth. Here, we characterize a fatty acid amide hydrolase (FAAH) from a growth-associated intestinal strain of Faecalibacterium prausnitzii cultured from these children. This enzyme, expressed and purified from Escherichia coli, hydrolyzes a variety of N-acylamides, including oleoylethanolamide (OEA), neurotransmitters, and quorum sensing N-acyl homoserine lactones; it also synthesizes a range of N-acylamides, notably N-acyl amino acids. Treating germ-free mice with N-oleoylarginine and N-oleolyhistidine, major products of FAAH OEA metabolism, markedly affected expression of intestinal immune function pathways. Administering MDCF to Bangladeshi children considerably reduced fecal OEA, a satiety factor whose levels were negatively correlated with abundance and expression of their F. prausnitzii FAAH. This enzyme, structurally and catalytically distinct from mammalian FAAH, is positioned to regulate levels of a variety of bioactive molecules.</p> <p>&nbsp;</p>

Analysis of the AlphaFold-Multimer structural models with respect to the melittin RDCs measured with the Pf1 alignment media. SVD fitting of the RDC alignment tensor parameters was done for residues 3-23 in the AF-M models and residues 3-25 in the 2MLT crystal structure. The AF-M model confidence score is a prediction of the similarity between the AF-M model and the true oligomeric structure. The RMSD listed in the final column is the backbone RMSD between the AF-M structural models and the 2MLT X-ray crystal structure tetramer for residues 1-23.</p> <p><strong>Table S5</strong>.

Cystargolide-based amide and ester Pz analogs as proteasome inhibitors and anticancer agents

<p>A series of cystargolide-based beta-lactone analogs containing nitrogen atoms at the Pz portion of the scaffold were prepared and evaluated as proteasome inhibitors and for their cytotoxicity profile towards several cancer cell lines. Inclusion of one, two or even three nitrogen atoms at the Pz portion of the cystargolide scaffold is well-tolerated, producing analogs with low nanomolar proteasome inhibition activity, in many cases superior to carfilzomib. Additionally, analog 8g, containing an ester and pyrazine group at Pz, was shown to possess significant activity towards RPMI 8226 cells (IC50 = 21 nM) and to be less cytotoxic towards the normal tissue model MCF10A cells than carfilzomib.</p>
