Drug-like inhibitors are often designed by mimicking cofactor or substrate interactions with enzymes. However, as active sites are comprised of conserved residues, it is difficult to identify the critical interactions needed to design selective inhibitors. We are developing an approach, named RADD (resistance analysis during design), which involves engineering point mutations in the target to generate active alleles and testing compounds against them. Mutations that alter compound potency identify residues that make key interactions with the inhibitor and predict target-binding poses. Here, we apply this approach to analyze how diaminotriazole-based inhibitors bind spastin, a microtubule-severing AAA (ATPase associated with diverse cellular activities) protein. The distinct binding poses predicted for two similar inhibitors were confirmed by a series of X-ray structures. Importantly, our approach not only reveals how selective inhibition of the target can be achieved but also identifies resistance-conferring mutations at the early stages of the design process.

Two new (4-5) and a known (3) derivatives of 1,2,4-triazolo [1,5-a]pyrimidine are synthesized and characterized through spectroscopic NMR, FT-IR and single crystal X-ray diffraction techniques. Along with experimental data, the predicted spectral data are obtained using density functional theory (DFT) at the B3LYP/6-31 + G (d,p) level of theory. The closest contacts between active atoms of the compounds are identified through Hirshfeld surface analysis and electrostatic potential map (EPM) studies. Relatively, good correlations were found between the experimental and predicted spectroscopic data with correlation coefficients higher than 90%. Hirshfeld surface analysis and EPM reveal that the closest interaction between the units of the compounds are between hydrogen atoms (39.6-46.3%). The antioxidant activity of 3-5 is evaluated using DPPH free radical scavenging and ferric reducing antioxidant power assays. (C) 2018 Elsevier B.V. All rights reserved.

Aminotriazole (AT), an organic heterocyclic compound, is an unselective herbicide used to deal with a large assortment of weeds by preventing the biosynthesis of carotenoids. It is a malignant agent to human beings as well as to animals. This study is focused on the nanomolar detection of AT with multiwalled carbon nanotubes along with calcium-doped zinc oxide nanoparticles adapted for a nano-composite dependent glassy carbon electrode (MWCNTs/Ca-ZnO/GCE). The developed MWCNTs/Ca-ZnO/GCE showed an excellent electrocatalytic response to AT in 3.0 pH of 0.2 M phosphate buffer solution (PBS). There was an increase in the peak current of AT, i.e., 7.726 mu A, with MWCNTs/Ca-ZnO/GCE when it was compared with the peak current of AT at the bare glassy carbon electrode (GCE), 3.478 mu A, due to the semiconducting properties of the doped nanoparticles. Various techniques were employed to study the different parameters such as scan rate, pH variations, and concentration variations by cyclic voltammetry (CV), square wave voltammetry (SWV), and linear sweep voltammetry (LSV) in order to probe the mechanism, number of participating electrons, type of process, detection limit, and quantification limit. The Ca-ZnO nanoparticles (NPs) were synthesized at the proportion of 5.0% and these were characterized by energy dispersive X-ray analysis (EDX), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD). The developed sensor was applied for real sample analysis like soil and water by quantifying the AT in the samples and the output was found to be precise with good recovery results.

A rapid and efficient method based on solid phase extraction and liquid chromatography-tandem mass spectrometry was validated, allowing the determination of the endocrine-disrupting herbicides (acetochlor, alachlor, amitrole and atrazine), fungicides (carbendazim, triadimefon, penconazole and propiconazole), and insecticides (carbaryl and carbofuran) in drinking water. Low method detection limits (0.01-0.64 ng/L) and method quantification limits (0.03-2.13 ng/L) were obtained with satisfactory recoveries and precision for the endocrine-disrupting pesticides. The method was applied for real drinking water samples collected in the area of the city of Hangzhou (Zhejiang, China); the results showed that carbendazim, atrazine and acetochlor were detected in the drinking water samples and acetochlor was the most detected analyte.

Large amounts of effectors are secreted by the oesophageal glands of plant-parasitic nematodes, but their molecular mode of action remains largely unknown. We characterized aMeloidogyne incognitaprotein disulphide isomerase (PDI)-like effector protein (MiPDI1) that facilitates nematode parasitism. In situhybridization showed thatMiPDI1was expressed specifically in the subventral glands ofM. incognita. It was significantly upregulated during parasitic stages. Immunolocalization demonstrated MiPDI1 secretionin plantaduring nematode migration and within the feeding cells. Host-induced silencing of theMiPDI1gene affected the ability of the nematode to infect the host, whereasMiPDI1expression inArabidopsisincreased susceptibility toM. incognita, providing evidence for a key role of MiPDI1 inM. incognitaparasitism. Yeast two-hybrid, bimolecular fluorescence complementation and coimmunoprecipitation assays showed that MiPDI1 interacted with a tomato stress-associated protein (SlSAP12) orthologous to the redox-regulated AtSAP12, which plays an important role in plant responses to abiotic and biotic stresses.SAP12silencing or knocking out inNicotiana benthamianaand Arabidopsis increased susceptibility toM. incognita. Our results suggest that MiPDI1 acts as a pathogenicity factor promoting disease by fine-tuning SAP-mediated responses at the interface of redox signalling, defence and stress acclimation in Solanaceae andArabidopsis.

Graphene nanomaterials have attracted a great interest during the last years for different applications, but their possible impact on different biological systems remains unclear. Here, an assessment to understand the toxicity of commercial polycarboxylate functionalized graphene nanoplatelets (GN) on the unicellular fungal model Saccharomyces cerevisiae was performed. While cell proliferation was not negatively affected even in the presence of 800 mg L-1 of the nanomaterial for 24 hours, oxidative stress was induced at a lower concentration (160 mg L-1), after short exposure periods (2 and 4 hours). No DNA damage was observed under a comet assay analysis under the studied conditions. In addition, to pinpoint the molecular mechanisms behind the early oxidative damage induced by GN and to identify possible toxicity pathways, the transcriptome of S. cerevisiae exposed to 160 and 800 mg L-1 of GN was studied. Both GN concentrations induced expression changes in a common group of genes (337), many of them related to the fungal response to reduce the nanoparticles toxicity and to maintain cell homeostasis. Also, a high number of genes were only differentially expressed in the GN800 condition (3254), indicating that high GN concentrations can induce severe changes in the physiological state of the yeast.

Phenacylbromide derivatives constitute a multilateral group of precursors for the synthesis of numerous heterocycles of organic compounds. Briefly, 5-(2-bromo-acetyl)-substituted-thiophene derivative has been used as a synthon for synthesis of new thiophene-containing compounds through the reaction with nucleophilic nitrogen compounds and thioamides. The suggested structures of the newly synthesized thiophene compounds were confirmed and assured with different spectroscopic tools and with CHN elemental analysis. Additionally, the antimicrobial activity of these thiophene compounds was recorded to investigate their potency against various types of bacteria and fungi. Results showed that these compounds exhibit significant inhibitory activity against the growth of tested bacterial and fungal strains and that some derivatives were more potent than the employed reference drugs.
