The EFSA ‘Guidance on tiered risk assessment for edge-of-field surface waters’ underscores the importance of in silico models to support the pesticide risk assessment. The aim of this work was to use in silico models starting from an available, structured and harmonized pesticide dataset that was developed for different purposes, in order to stimulate the use of QSAR models for risk assessment. The present work focuses on the development of a set of in silico models, developed to predict the aquatic toxicity of heterogeneous pesticides with incomplete/unknown toxic behavior in the water compartment. The generated models have good fitting performances (R-2 : 0.75-0.99), they are internally robust (Q(2) loo: 0.66-0.98) and can handle up to 30% of perturbation of the training set (Q(2) Imo: 0.64-0.98). The absence of chance correlation was guaranteed by low values of R-2 calculated on scrambled responses (R-2 Y-scr: 0.11-0.38). Different statistical parameters were used to quantify the external predictivity of the models (CCCext: 0.73-0.91, Q(2) ext-Fn: 0.53-0.96). The results indicate that all the best models are predictive when applied to chemicals not involved in the models development. In addition, all models have similar accuracy both in fitting and in prediction and this represents a good degree of generalization. These models may be useful to support the risk assessment procedure when experimental data for key species are missing or to create prioritization lists for the general a priori assessment of the potential toxicity of existing and new pesticides which fall in the applicability domain.

In this study, 2-urea-chitosan oligosaccharide derivatives (2-urea-COS derivatives) and 2,6-diurea-chitosan oligosaccharide derivatives (2,6-diurea-COS derivatives) were successfully designed and synthesized via intermediate 2-methoxyformylated chitosan oligosaccharide. All samples were characterized and compared based on FT-IR, H-1 NMR spectroscopy, and elemental analysis. The antifungal effects of COS derivatives were tested against Fusarium oxysporum f. sp. niveum, Phomopsis asparagus, and Botrytis cinereal. Their antioxidant properties, including superoxide radicals’ scavenging activity, hydroxyl radicals’ scavenging activity, and DPPH radicals’ scavenging activity were also explored within different concentrations. COS derivatives bearing urea groups showed improved bioactivity compared with pristine COS and 2,6-diurea-COS derivatives had a higher biological activity than 2-urea-COS derivatives in tested concentrations. Additionally, L929 cells were used to carry out cytotoxicity test of COS and COS derivatives by CCK-8 assay. The results indicated that some of samples showed low cytotoxicity. These findings offered a suggestion that COS derivatives bearing urea groups are promising biological materials.

Cationic polymers are promising antibacterial agents because bacteria have a low propensity to develop resistance against them, but they usually have low biocompatibility because of their hydrophobic moieties. Herein, we report a new biodegradable and biocompatible chitosan-derived cationic antibacterial polymer, 2,6-diamino chitosan (2,6-DAC). 2,6-DAC shows excellent broad-spectrum antimicrobial activity with minimum inhibitory concentrations (MICs) of 8-32 mu g/mL against clinically relevant and multidrug-resistant (MDR) bacteria including Listeria monocytogenes, Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Acinetobacter baumannii. Furthermore, 2,6-DAC shows an excellent synergistic effect with various clinically relevant antibiotics proved by decreasing the MICs of the ntibiotics against MDR A. baumannii and methicillin-resistant Staphylococcus aureus to <1 mu g/mL. In vivo biocompatibility of 2,6-DAC is proved by a dosage of 100 mg/kg compound via oral administration and 25 mg/kg compound via intraperitoneal injection to mice; 2,6-DAC does not cause any weight loss and any significant change in liver and kidney biomarkers or the important blood electrolytes. The combinations of 2,6-DAC together with novobiocin and rifampicin show >2.4 log(10) reduction of A. baumannii in murine intraperitoneal and lung infection models. The novel chitosan derivative, 2,6-DAC, can be utilized as a biocompatible broad-spectrum cationic antimicrobial agent alone or in synergistic combination with various antibiotics.

Purpose To investigate the added value of 6-(18F]-fluoro-L-3,4-dihydroxyphenylalanine (FDOPA) PET to radiotherapy planning in glioblastoma multiforme (GBM). Methods From September 2017 to December 2020, 17 patients with GBM received external beam radiotherapy up to 60 Gy with concurrent and adjuvant temozolamide. Target volume delineations followed the European guideline with a 2-cm safety margin clinical target volume (CTV) around the contrast-enhanced lesion+resection cavity on MRI gross tumor volume (GTV). All patients had FDOPA hybrid PET/MRI followed by PET/CT before radiotherapy planning. PET segmentation followed international recommendation: T/N 1.7 (BTV1.7) and T/N 2 (BTV2.0) SUV thresholds were used for biological target volume (BTV) delineation. For GTV-BTVs agreements, 95% of the Hausdorff distance (HD95%) from GTV to the BTVs were calculated, additionally, BTV portions outside of the GTV and coverage by the 95% isodose contours were also determined. In case of recurrence, the latest MR images were co-registered to planning CT to evaluate its location relative to BTVs and 95% isodose contours. Results Average (range) GTV, BTV1.7, and BTV2.0 were 46.58 (6-182.5), 68.68 (9.6-204.1), 42.89 (3.8-147.6) cm(3), respectively. HD95% from GTV were 15.5 mm (7.9-30.7 mm) and 10.5 mm (4.3-21.4 mm) for BTV1.7 and BTV2.0, respectively. Based on volumetric assessment, 58.8% (28-100%) of BTV1.7 and 45.7% of BTV2.0 (14-100%) were outside of the standard GTV, still all BTVs were encompassed by the 95% dose. All recurrences were confirmed by follow-up imaging, all occurred within PTV, with an additional outfield recurrence in a single case, which was not DOPA-positive at the beginning of treatment. Good correlation was found between the mean and median values of PET/CT and PET/MRI segmented volumes relative to corresponding brain-accumulated enhancement (r = 0.75; r = 0.72). Conclusion (18F)FDOPA PET resulted in substantial larger tumor volumes compared to MRI; however, its added value is unclear as vast majority of recurrences occurred within the prescribed dose level. Use of PET/CT signals proved to be feasible in the absence of direct segmentation possibilities of PET/MR in TPS. The added value of (18F)FDOPA may be better exploited in the context of integrated dose escalation.

Artificial enzyme mimics have recently emerged as alternative biocatalysts for overcoming the intrinsic fragility of natural enzyme in practical applications. However, current researches regarding mimetic enzymes are still confined to very few reaction types, with artificial oxidoreductases as dominance. Herein, inspired by nature, we designed and fabricated a range of Zn-Triazole coordination polymers (ZnTazs) that presented similar co-ordination structures with the active site of natural carbonic anhydrase. (CA II). These synthesized compounds exhibited inherently mimetic function with natural CA for catalyzing the hydrolysis of p-nitrophenyl acetate (p-NPA). Especially, the initial hydrolysis rate (V-0) of p-NPA catalyzed by ZnTaz-1 (Zn-5(bta)(6)(NO3)(4) center dot H2O) and ZnTaz-2 (Zn-3(OH)(2)(btca)(2) center dot DMF center dot 4 H2O) reached 42.1 and 73.8 nM.s(-1), respectively. Meanwhile, ZnTaz-1 and ZnTaz-2 showed favorable recyclability, and excellent stability towards various pH values and organic solvents, which are of great significance for practical employment. Moreover, they could also promote the efficient hydration and sequestration of greenhouse gas CO2 in aqueous medium. Based on this work, we aim to provide more theoretical and practical basis for rational design of CA mimics from the inspiration of natural enzyme, as well as propose a potential strategy for tackling the CO2 crisis.

A novel series of acetamide-substituted derivatives and two prodrugs of doravirine were designed and synthesized as potent HIV-1 NNRTIs by employing the structure-based drug design strategy. In MT-4 cell-based assays using the MTT method, it was found that most of the new compounds exhibited moderate to excellent inhibitory potency against the wild-type (WT) HIV-1 strain with a minimum EC50 value of 54.8 nM. Among them, the two most potent compounds 8i (EC50 = 59.5 nM) and 8k (EC50 = 54.8 nM) displayed robust activity against WT HIV-1 with double-digit nanomolar EC50 values, being superior to lamivudine (3TC, EC50= 12.8 mu M) and comparable to doravirine (EC50= 13 nM). Besides, 8i and 8k shown moderate activity against the double RT mutant (K103N + Y181C) HIV-1 RES056 strain. The HIV-1 RT inhibition assay further validated the binding target. Molecular simulation of the representative compounds was employed to provide insight on their structure-activity relationships (SARs) and direct future design efforts. Finally, the aqueous solubility and chemical stability of the prodrugs 9 and 10 were investigated in detail.

A thermo-responsive copolymer with a gas-switchable LCST-type phase transition was synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization of N-isopropylacrylamide (NIPAM) and glycidyl methacrylate (GMA), followed by post-polymerization functionalization with sodium 3-amino-1,2,4-triazole (ATANa). Incorporating ionic moieties provides an elevated cloud point of 61 degrees C. Importantly, both CO2 and SO2 cause a reduction in the cloud point of the polymer solution. The CO2-triggered system can be easily and fully recovered to its initial state by introducing an inert gas (e.g. N-2), whereas the SO2-triggered system shows only partial recovery. The pH-dependent phase transition behaviors confirm that the gas bubbling-induced pH changes contribute to the gas-switchable cloud point of P(NIPAM-co-(GMA-ATANa)). In addition, P(NIPAM-co-(GMA-ATA)) (ATA: 3-amino-1,2,4-triazole), a counterpart of P(NIPAM-co-(GMA-ATANa)), was prepared and the relevant solution phase transition behavior was studied. Its cloud point shift in response to gas bubbling and pH adjustment is opposite to that of P(NIPAM-co-(GMA-ATANa)), indicating that the latter does not result from the protonation of amidine groups. Alternatively, a reversible H+-induced decrease in hydrophilicity was thus proposed. This contribution enriches the family of thermo-responsive polymers by introducing gas-sensitive polyelectrolytes and also broadens the scope of gas-responsive smart materials.
