Polyfunctional 3-chloro-3-(4-chlorocoumarin-3-yl)prop-2-enal (1) used as a precursor for heterocyclic synthesis. Dichloro-aldehyde 1 was allowed to react with variable nucleophilic reagents, and a diversity of heterocyclic systems linked coumarin moiety at position 3 was synthesized. The reaction of compound 1 with guanidine and cyanoguanidine produced 3-(pyrimidin-4-yl)-4-chlorocoumarins 2 and 3. Treating compound 1 with 3-amino-1,2,4-triazole and 2-aminobenzimidazole yielded triazolo[4,3-a]pyrimidine 4 and pyrimido[1,2-a]benzimidazole 5. The treatment of compound 1 with cyanoacetamide, N-benzyl-2-cyanoacetamide, and 1H-benzimidazolylacetonitrile gave 2(1H)-pyridones 6, 7 and pyrido[1,2-a]benzimidazole 8. The reaction of compound 1 with 5-amino-3-methyl-1H-pyrazole and 6-aminouracil afforded pyrazolo[3,4-b]pyridine 9 and pyrido[2,3-d]pyrimidine 10, respectively. Compound 1 reacted with ethylenediamine, o-phenylenediamine, o-aminophenol, and o-aminothiophenol leading to 5-(imidazolylmethyl)chromeno[4,3-e] [1,4]diazepine (12), 3-(benzodiazepin/benzoxazepin-2-yl)-4-chlorocoumarins 13, 14, and 6-(benzothiazol-2-ylmethyl)chromeno[4,3-b][1,5]benzothiazepine 16, respectively. Structures of the new synthesized products were deduced on the basis of their analytical and spectral data.

The use of additive-manufactured components in medical applications, specifically medical devices (e.g., orthopedic casts), has increased in recent years. Such devices may be fabricated at the point of care using consumer-grade additive manufacturing. Limited studies have been conducted to evaluate the extractable substances of these devices. Chemical characterization followed by toxicological risk assessment is one means of evaluating safety of devices. This study was designed to determine the extractables profile of additive-manufactured materials according to filament grade and post-processing method. Feedstocks for additive manufacturing were tested as filament and manufactured casts, while the cast from consumer-grade filament (CGF) was post-processed. Samples were extracted using three solvents of varying polarities. Extracts were analyzed by gas chromatography/mass spectrometry (GC/MS) and liquid chromatography/mass spectrometry (LC/MS) techniques. In GC/MS analysis, isopropanol extracts generated fewer compound identifications for USP Class VI filament (USPF)-based casts (3) compared with the respective filament (17) while hexane generated the most compound identifications for the finished cast manufactured from CGF. CGF was found to have the highest number of nonvolatile extractables for isopropanol (15) and hexane (34) by positive ion LC/MS. Additionally, CGF produced more non-polar extractables in hexane than the USPF. A known polymer byproduct and potential genotoxicant, styrene acrylonitrile (SAN) trimer, was one of the compounds identified in both GC/MS and LC/MS at quantities ranging from 19 to 270 mu g g(-1). Overall these results suggested that the extractables profile was affected by the filament material, printing procedure, and post-processing method.

An acid-base bifunctional zeolitic imidazolate framework catalyst (ZIF8-A61-SO3H) with amine and sulfonic acid groups was successfully prepared through simple two step post-synthetic modification: preparation of aminefunctionalized ZIF-8 with amine contents of 61% (ZIF8-A61) by the ligand exchange of 2-mIM with 3-amino1,2,4-triazole (Atz), followed by the sulfonic acid functionalization by the ring-opening reaction of 1,3-propanesultone with -NH2 groups in ZIF8-A61. Amine-functionalized ZIF8-A materials with difference amine contents (15%, 34%, and 61%, respectively) were also prepared by controlling the synthesis time. All obtained ZIF catalysts evaluated as a heterogeneous catalyst for one-pot deacetalization-Knoevenagel condensation tandem reaction. Compared with ZIF-8 and amine-functionalized ZIF-8 catalysts, ZIF8-A61-SO3H catalyst showed good catalytic performance with 100% conversion of the reactant and 98% selectivity of the final Knoevenagel product. An enhanced catalytic activity can be attributed to the co-existence of site-isolated acid-base groups on the ZIF8-A61-SO3H catalyst in close proximity. The heterogeneous nature of the catalytic system was confirmed by a hot-filtering test and the catalyst also exhibited reusable in the five repeated cycles. A plausible catalytic mechanism of deacetalization-Knoevenagel condensation reaction over ZIF8-A61-SO3H was also proposed.

Despite the richness of data collected on pesticide concentrations in ambient air in France, knowledge on this topic remains partial and heterogeneous in the absence of specific regulations. The population exposure remains thus difficult to estimate; therefore it was necessary to define modalities for implementing national monitoring of pesticides in ambient air in metropolitan France and in the overseas territories. The objective of this work was to identify which active substances (a.s.) have to be monitored in priority. As part of a collective expertise, a group of multidisciplinary experts has developed a method to rank active substances authorised as plant protection products, biocides and antiparasitic agents, which were available on the French market in 2015. A 3-steps approach has been developed. The first step consisted of a theoretical approach based on a hierarchy of substances according to four criteria: (a) national uses, (b) emission potential to the air, (c) persistence in the air, and (d) chronic toxicity. The three first criteria give information on their potential to be present in the atmosphere, and the fourth criterion allows to consider their potential of hazard. The second step was an observational approach based on existing database on pesticide air measurements in France. In the third step, both approaches were combined using decision trees to select priority pesticides. Among the 1316 a.s. first identified from the EU Pesticides database, 90 were selected, among which 43 required metrological and/or analytical development. The experts recommended confirming the relevance of performing a longer term monitoring of these a.s. after a one-year exploratory campaign. The proposed method is reproduceable, transparent, easy to update (e.g. in the light of a change in product authorization), and can be adapted to other agricultural and geographical conditions, and objectives (e.g. monitoring of the ecotoxicological effects of pesticides).

As the use of the new insensitive munitions compound 3-nitro-1,2,4-triazol-5-one (NTO) increases, wastewaters, runoff and groundwater containing NTO will be generated. Little is known about the fate of NTO during biological wastewater treatment. The objective of this study was to explore the ability of wastewater sludges to promote the biotransformation of NTO. Three different sludges, i.e., anaerobic granular sludge, anaerobic digested sludge, and return activated sludge, were used to study the biotransformation of NTO under anaerobic conditions. Three different electron donor amendments were compared- hydrogen, ethanol, and acetate. Mixed microbial communities in each of the three sludge sources were effective in the reductive biotransformation of NTO. 3-amino-1,2,4-triazol-5-one (ATO) was observed as the major product of NTO biotransformation. The highest maximum specific rate of NTO reduction, about 120 mg NTO/g volatile suspended solids/d, was observed in anaerobic granular sludge with hydrogen or ethanol supplied as electron donors. NTO biotransformation to ATO by anaerobic digested sludge was also studied under denitrifying conditions. In this case, reduction of NTO started only after complete denitrification of added nitrate. An important implication of this paper is that sludge from wastewater treatment plants can rapidly and readily reduce NTO to ATO. [GRAPHICS] .

Cerrena unicolor is a wood-degrading basidiomycete with ecological and biotechnological importance. Comprehensive Biolog-based analysis was performed to assess the metabolic capabilities and sensitivity to chemicals of C. unicolor FCL139 growing in various sawdust substrates and light conditions. The metabolic preferences of the fungus towards utilization of specific substrates were shown to be correlated with the sawdust medium applied for fungus growth and the light conditions. The highest catabolic activity of C. unicolor was observed after fungus precultivation on birch and ash sawdust media. The fungus growing in the dark showed the highest metabolic activity which was indicated by capacity to utilize a broad spectrum of compounds and the decomposition of 74/95 of the carbon sources. In all the culture light conditions, p-hydroxyphenylacetic acid was the most readily metabolized compound. The greatest tolerance to chemicals was also observed during C. unicolor growth in darkness. The fungus was the most sensitive to nitrogen compounds and antibiotics, but more resistant to chelators. Comparative analysis of C. unicolor and selected wood-decay fungi from different taxonomic and ecological groups revealed average catabolic activity of the fungus. However, C. unicolor showed outstanding capabilities to catabolize salicin and arbutin. The obtained picture of C. unicolor metabolism showed that the fungus abilities to decompose woody plant material are influenced by various environmental factors.

Reactivity of the singlet oxygen (SO), which is assumed to be one of the important oxidizers in natural waters, towards to a set of persistent herbicides, was measured for the first time using time resolved luminescence technique. It was observed that rate constants of SO reactions with the majority of studied herbicides are less than 10(6) M(-1)s(-1) allowing to conclude about negligible participation of SO in oxidation of the compounds in natural waters.

Background: Presently, rise in the infectious diseases and subsequent development of drug resistance, is a global threat to human health. However, much efforts are being made by scientists, to develop novel antimicrobials, and also to improve the efficacy of available drugs, in order to combat the life-threatening infections. Objective: Synthesis and characterization of azole functional polymer systems for antimicrobial applications. Materials and Methods: Poly(glycidyl methacrylate) (PGMA), was produced by free radical polymerization of the monomer, glycidyl methacrylate (GMA). Different azole functional PGMAs were produced, through chemical modification with imidazole (Im), 1H-1,2,4-triazole (Tri) and 3-amino-1,2,4-triazole (ATri), to get PGMA-Imi, PGMA-Tri and PGMA-ATri, respectively. The structure was confirmed by Fourier transform infrared spectroscopy (FT-IR), thermal properties were investigated by Thermogravimetric Analysis (TGA), and surface morphology was studied by scanning electron microscopy (SEM). Newly synthesized derivatives were further explored, for their antibacterial and anticandidal activities. Results: All the three synthesized and characterized derivatives, displayed a significant activity against the tested microorganisms. The minimum inhibitory concentration (MIC) and minimum bactericidal/fungicidal concentration (MBC/MFC), recorded against Staphylococcus aureus (S. aureus), was 0.5 &1mg/ml for PGMA-Imi, followed by PGMA-ATri & PGMA-Tri, respectively, followed by E. coli with, 1 & 2 mg/ml, 4 & 8 mg/ml, 4& 8 mg/ml, respectively, whereas the maximum MIC & MFC was recorded against C. albicans i.e., 8 & 16 mg/ml, 4 & 8 mg/ml ,4 & 8 mg/ml for PGMA-ATri, PGMA-Tri, PGMA-Imi, respectively. Conclusion: In the present work, we report on the state-of-the-art, azole functional polymer systems for antimicrobial applications. These findings suggest that the synthesized azole functional polymer films have antimicrobial properties, which could be potential candidates for coating applications in the biomedical and wastewater treatment field.

A three-descriptor quantitative structure-activity/toxicity relationship (QSAR/QSTR) model was developed for the skin permeability of a sufficiently large data set consisting of 274 compounds, by applying support vector machine (SVM) together with genetic algorithm. The optimal SVM model possesses the coefficient of determination R-2 of 0.946 and root mean square (rms) error of 0.253 for the training set of 139 compounds; and a R-2 of 0.872 and rms of 0.302 for the test set of 135 compounds. Compared with other models reported in the literature, our SVM model shows better statistical performance in a model that deals with more samples in the test set. Therefore, applying a SVM algorithm to develop a nonlinear QSAR model for skin permeability was achieved.

Moreover, the three coordination polymers have been characterized by IR spectroscopy, elemental analysis, single-crystal X-ray diffraction, and powder X-ray diffraction techniques. Complex 1 reveals a 2D layer structure, which is further connected through pi-pi stacking interactions forming a 3D supramolecular network. Complex 2 exhibits a 3D porous framework with 1D open channels. Complex 3 shows a 3D pillared-layer framework. Notably, the thermal decomposition processes of 1-3 were investigated by simultaneous TG-DSC techniques. The TG curves reveal that complexes 1-3 possess pretty good thermostability up to 321 degrees C, 416 degrees C and 418 degrees C, respectively. The apparent activation energy E (E-1 = 194.975 kJ mol(-1), E-2 = 220.360 kJ mol(-1), E-3 = 223.600 kJ mol(-1)) and the pre exponential factor A of skeleton collapse for the complexes 1-3 were calculated by the integral Kissinger’s method and Ozawa-Doyle’s method. The structural stability could be illustrated from the point of thermal decomposition kinetics.
