As an amide fungicide, fenhexamid has been extensively used to control botrytis and sderotinia as well as antagonize the resistant bacteria produced by other pesticides. But because of the accumulation of residues in fruit and vegetable products, it may have an adverse effect on the health of human and animals. In this work, the exploration of the interaction between fenhexamid and calf thymus DNA (ct-DNA) was carried out by fluorescence spectroscopy, IJV-vis spectroscopy, circular dichroism, viscosity measurement, melting measurements, molecular docking and molecular dynamics simulation. The results implied that fenhexamid bound onto ct-DNA in terms of groove binding. And the outcomes from circular dichroism measurements demonstrated a slight change in the ct-DNA helical structure during the binding process. In addition, the combination ratio of fenhexamid with ct-DNA was 1:1 and the association constant was 2.52 x 10(3) M-1 at 298 K. The measured thermodynamic parameters indicated that hydrogen bonding interaction and van der Waals forces become more dominant during interacting fenhexamid with ct-DNA, which was further confirmed through computer simulation technique.

Hunting small molecules as anti-inflammatory agents/drugs is an expanding and successful approach to treat several inflammatory diseases such as cancer, asthma, arthritis, and psoriasis. Besides other methods, inflammatory diseases can be treated by lipoxygenase inhibitors, which have a profound influence on the development and progression of inflammation. In the present study, a series of new N-alkyl/aralky/aryl derivatives (7a-o) of 2-(4-phenyl-5-(1-phenylcarbamoyl)piperidine-4H-1,2,4-triazol-3-ylthio)acetamide was synthesized and screened for their inhibitory potential against the enzyme 15-lipoxygenase. The simple precursor ethyl piperidine-4-carboxylate (a) was successively converted into phenylcarbamoyl derivative (1), hydrazide (2), semicarbazide (3) and N-phenylated 5-(1-phenylcarbamoyl)piperidine-1,2,4-triazole (4), then in combination with electrophiles (6a-o) through further multistep synthesis, final products (7a-o) were generated. All the synthesized compounds were characterized by FTIR, H-1, C-13 NMR spectroscopy, EIMS, and HREIMS spectrometry. Almost all the synthesized compounds showed excellent inhibitory potential against the tested enzyme. Compounds 7c, 7f, 7d, and 7g displayed potent inhibitory potential (IC50 9.25 +/- 0.26 to 21.82 +/- 0.35 mu M), followed by the compounds 7n, 7h, 7e, 7a, 7b, 7l, and 7o with IC50 values in the range of 24.56 +/- 0.45 to 46.91 +/- 0.57 mu M. Compounds 7c, 7f, 7d exhibited 71.5 to 83.5% cellular viability by MTT assay compared with standard curcumin (76.9%) when assayed at 0.125 mM concentration. In silico ADME studies supported the drug-likeness of most of the molecules. In vitro inhibition studies were substantiated by molecular docking wherein the phenyl group attached to the triazole ring was making a pi-delta interaction with Leu607. This work reveals the possibility of a synthetic approach of compounds in relation to lipoxygenase inhibition as potential lead compounds in drug discovery.

Ethnopharmacological relevance: The dried and nearly ripe fruits of Tetradium ruticarpum (A. Juss.) T.G. Hartley (TR) have long been used in treating headache and gastrointestinal disorders in oriental medicine. TR is usually processed by stir-frying with licorice extract before use. Although processing procedure is considered as the way to relieve pungent smell, reduce toxicity, and improve efficacy, its effects on TR’s toxicity and efficacy and bioactive compound profiles are largely unknown. Aim of the study: The purposes of the study are to evaluate the acute toxicity, efficacy and variation of toxic and effective components of TR before and after processing, and to explore the possible mechanism of how the processing procedure affect the quality of TR as a herbal medicine. Materials and methods: Volatile oil, aqueous extract and ethanol extract of raw and processed TR were tested for their acute toxicity, analgesic, and anti-inflammatory effects in mouse models, respectively. To identify potential toxic and effective components, the extracts were analyzed with gas chromatography-mass spectrometry and ultra-performance liquid chromatography – quadrupole time-of-flight mass spectrometry, followed by foldchange-filtering analysis. Results: LD(50)( )and LD5 tests indicated that although the aqueous extract has higher toxicity than volatile oil and ethanol extract, the use of TR is safe under the recommended does. The processing procedure could effectively decrease the toxicity of all three extracts with the largest decrease in volatile oil, which is likely due to the loss of volatile compounds during processing. Analgesic and anti-inflammatory studies suggested that volatile oil and ethanol extract of TR have better efficacy than the aqueous extract and the processing procedure significantly enhanced the efficacy of these two former extracts, whereas processing showed no substantially effects on the bioactivities of aqueous extract. Integrated analysis of animal trial and chromatographic analyses indicated that indole and quinolone type alkaloids, limonoids, amides and 18p-glycyrrhetinic acid were identified as the potential main contributors of TR’s efficacy, whereas hydroxy or acetoxy limonoid derivates and coumarins could be the major causes of toxicity. Moreover, the reduced toxicity and improved efficacy of the processed TR are liked due to the licorice ingredients and altered alkaloids with better solubility. Conclusions: In summary, the integrated toxicity and efficacy analyses of volatile, aqueous and ethanol extracts of TR indicated that the processing procedure could effectively reduce its acute toxicity in all three extracts and enhance its analgesic and anti-inflammatory effects in volatile and ethanol extracts. The promising candidate compounds related to the toxicity and efficacy of TR were also identified. The results could expand our understanding of the value of the standard processing procedure of TR, be valuable to the quality control of TR manufacturing and administration, as well as support clinical rational and safety applications of this medicinal plant.

The removal of emerging environmental pollutants in water and wastewater is essential for high drinking water quality or for discharge to the environment. Electrochemical treatment is a promising technology shown to degrade undesirable organic compounds or metals via oxidation and reduction, and carbon-based electrodes have been reported. Here, we fabricated a robust, porous laser-induced graphene (LIG) electrode on a commercial water treatment membrane using the multilasing technique and demonstrated the electrochemical removal of iohexol, an iodine contrast compound, and chromium(VI), a highly toxic heavy metal ion. Multiple lasing resulted in a more ordered graphitic lattice, a more physically robust carbon layer, and a 3-4-fold higher electrical conductivity. These properties ultimately led to a more efficient electrochemical process, and the optimized LIG electrodes showed a higher hydrogen peroxide (H2O2) generation. At 3 V, 90% of Cr(VI) was removed after 6 h and reached >95% removal after 8 h at pH 2. Cr(VI) was mainly reduced to Cr(III), with small amounts of Cr(I) and Cr(0), which were partially deposited on the electrode membrane surface, confirmed with X-ray photoelectron spectroscopy and energy-dispersive X-ray spectroscopy analysis. Under the same conditions, 50% of iohexol was degraded after 6 h and the transformation products (TPs) were identified using ultra-performance liquid chromatography coupled with mass spectroscopy. A total of seven main intermediates were identified including deiodinated TPs (m/z = 695, 570, and 443), probably occurring via three transformation pathways including oxidative deiodination, amide hydrolysis, and deacetylation. The electrical energy costs calculated for the removal of 2 mg L-1 Cr(VI) was similar to$0.08/m(3) in this system. Taken together, the porous LIG electrodes might be utilized for electrochemical removal of emerging contaminants in multiple applications because they can be rapidly formed on flexible polymer substrates at low cost.

The amidation of long-chain fatty acids is the key step for preparing surfactants with excellent interfacial activity. Gas chromatography-mass spectrometry was employed to detect the reactants and products in the direct amidation reactions. The conversion and the concentration of the amides in the reaction process were also investigated to determine the best catalyst, the reaction rate constants, and activation energy. It was identified that the amidation reaction of the long-chain phenyl fatty acid was a zero-order reaction and 3,4,5-trifluorophenylboronic acid was the most effective catalyst by which the activation energy reduced to 55.79 kJ/mol from 95.44 kJ/mol. The method can be applied to other long-chain fatty acids, saturated or unsatureated. The turning-over-temperature was 156 degrees C, over which high yields can be achieved without any catalyst. These provide a reference for the preparation of long-chain fatty acid amides.

Nicotinamide (NAM) is an amide form of vitamin B3 and the precursor of nicotinamide adenine dinucleotide (NAD+), an essential co-enzyme of redox reactions for adenosine triphosphate (ATP) production and for other metabolic processes. As NAD+ status is critical in maintaining cellular energy, vitamin B3 deficiency mainly affects tissues that need high cellular energy causing pellagra and skin sun sensitivity. In animal models, NAD+ deficiency leads to UV sensitivity of the skin, impairs DNA damage response, and increases genomic instability and cancer incidence. Furthermore, NAD+ depletion is associated with human skin aging and cancer. NAM prevents the UV-induced ATP depletion boosting cellular energy and enhances DNA repair activity in vitro and in vivo. Moreover, NAM reduces skin cancer incidence and prevents the immune-suppressive effects of UV in mice. Thus, NAM is involved in the maintenance of genomic stability and may have beneficial effects against skin aging changes and tumor development. Clinical studies showed that topical use of NAM reduces cutaneous aging. Furthermore, oral NAM administration reduces the level of UV-mediated immunosuppression and lowers the rate of non-melanoma skin cancers in high-risk patients. Therefore, NAM replenishment strategy may be a promising approach for skin cancer chemoprevention.

Recently, a new nuclear Overhauser enhancement (NOE)-mediated saturation transfer effect at around -1.6 ppm from water, termed NOE(-1.6), was reported to show hypointense signals in brain tumors. Similar to chemical exchange saturation transfer or magnetization transfer (MT) effects, which depend on the solute pool concentration, the exchange/coupling rate, the solute transverse relaxation rate, etc., the NOE(-1.6) effect should also depend on these factors. Since the exchange rate is relevant to tissue pH, and the coupling rate and the solute transverse relaxation rate are relevant to the motional property of the coupled molecules, further studies to quantify the contribution from only the exchange/coupling rate and the solute transverse relaxation rate are always interesting. The purpose of this paper is to apply a ratiometric approach to the NOE(-1.6) effect to obtain a metric that is more specific to the NOE coupling rate and the solute transverse relaxation rate than the NOE(-1.6) signal amplitude. Simulations indicate that the ratiometric approach allows us to rule out nearly all of the non-specific factors including the solute pool concentration, solute and water longitudinal relaxation rates, direct water saturation, and semi-solid MT effects, and provides a more specific NOE coupling rate- and solute transverse relaxation rate-weighted signal. Animal studies show that the ratiometric NOE(-1.6) decreases dramatically in brain tumors, which suggests that the change in the NOE(-1.6) coupling rate and/or the solute transverse relaxation rate are major contributors to the previously observed hypointense NOE(-1.6) signal in tumors.

Polysuccinimide and its derivatives: Degradable and water soluble polymers (review)

Interest for water soluble polymers which show biocompatibility and degradability is growing due to their potential applications in medical sciences. Polysuccinimide (PSI), commonly synthesized through thermal polymerization, is a polyimide precursor for the production of such biocompatible and degradable polymers namely polyaspartic acid and various polyaspartamides. Polyaspartic acid is usually obtained by hydrolysis of PSI while polyaspartamide is produced by ring opening of PSI using a nucleophilic reagent. The presence of amide linkages in these polymers gives them peptide-like structures which is prone to hydrolysis and subsequent degradation. These derivatives could be potential substitutes for different polyamino acids in many medical applications. This review compiles the works carried out on developing polysuccinimide and its derivatives as well as the main synthetic routs and characterization methods.
