The increasing threat of antimicrobial resistance to all currently available therapeutic agents has urged the development of novel antimicrobials. In this context, a series of new benzoylthiourea derivatives substituted with one or more fluorine atoms and with the trifluoromethyl group have been tested, synthesized, and characterized by IR, NMR, CHNS and crystal X-ray diffraction. The molecular docking has provided information regarding the binding affinity and the orientation of the new compounds to Escherichia coli DNA gyrase B. The docking score predicted the antimicrobial activity of the studied compounds, especially against E. coli, which was further demonstrated experimentally against planktonic and biofilm embedded bacterial and fungal cells. The compounds bearing one fluorine atom on the phenyl ring have shown the best antibacterial effect, while those with three fluorine atoms exhibited the most intensive antifungal activity. All tested compounds exhibited antibiofilm activity, correlated with the trifluoromethyl substituent, most favorable in para position.

SDS of cas: 87-41-2. I found the field of Toxicology very interesting. Saw the article Association of electroanalytical and spectrophotometric methods to evaluate the antioxidant activity of isobenzofuranone in primary cultures of hippocampal neurons published in 2020, Reprint Addresses Nogueira, KDPC (corresponding author), Univ Fed Ouro Preto, Inst Ciencias Exatas Biol ICEB, Dept Ciencias Biol DECBI, Campus Morro Cruzeiro S-N, BR-35400000 Ouro Preto, MG, Brazil..

The isobenzofuran-1(3H)-ones (phthalides) exhibit various biological activities, including antioxidant activity on reactive oxygen species (ROS). An excess of ROS that cannot be naturally contained by cellular enzymatic systems is called redox imbalance, which damage cell membranes, proteins, and DNA, thereby possibly triggering neuronal death in several neurodegenerative diseases. Considering our ongoing efforts to find useful compounds to control redox imbalance, herein we evaluated the antioxidant activity of two phtalides (compounds 3 and 4), using primary cultures of hippocampal neurons. Spectrophotometric assays showed that compound 3 significantly reduced (p <= 0.05) ROS levels and lipid peroxidation compared to the control treatment, while compound 4 was unable at any of the tested concentrations. Despite their structural similarity, these compounds behave differently in the intracellular environment, which was reliably corroborated by the determination of oxidation potentials via cyclic voltammetry. It was demonstrated that compound 3 presents a lower oxidation potential. The combination of the mentioned methods allowed us to find a strong correlation between the chemical structure of compounds and their biological effects. Taking together, the results indicate that compound 3 presents desirable characteristics to act as a candidate pharmacological agent for use in the prevention and treatment of neurodegenerative diseases.

Synthetic polymer-based materials are ubiquitous in aquatic environments, where weathering processes lead to their progressive fragmentation and the leaching of additive chemicals. The current study assessed the chemical content of freshwater and marine leachates produced from car tire rubber (CTR), polypropylene (PP), polyethylene terephthalate (PET), polystyrene (PS) and polyvinyl chloride (PVC) microplastics, and their adverse effects on the microalgae Raphidocelis subcapitata (freshwater) and Skeletonema costatum (marine) and the Mediterranean mussel Mytilus galloprovincialis. A combination of non-target and target chemical analysis revealed a number of organic and metal compounds in the leachates, including representing plasticizers, antioxidants, antimicrobials, lubricants, and vulcanizers. CTR and PVC materials and their corresponding leachates had the highest content of tentatively identified organic additives, while PET had the lowest. The metal content varied both between polymer leachates and between freshwater and seawater. Notable additives identified in high concentrations were benzothiazole (CTR), phthalide (PVC), acetophenone (PP), cobalt (CTR, PET), zinc (CTR, PVC), lead (PP) and antimony (PET). All leachates, except PET, inhibited algal growth with EC50 values ranging from 0.5% (CTR) and 64% (PP) of the total leachate concentration. Leachates also affected mussel endpoints, including the lysosomal membrane stability and early stages endpoints as gamete fertilization, embryonic development and larvae motility and survival. Embryonic development was the most sensitive parameter in mussels, with EC50 values ranging from 0.8% (CTR) to 65% (PET) of the total leachate. The lowest impacts were induced on D-shell larvae survival, reflecting their ability to down-regulate motility and filtration in the presence of chemical stressors. This study provides evidence of the relationship between chemical composition and toxicity of plastic/rubber leachates. Consistent with increasing contamination by organic and inorganic additives, the leachates ranged from slightly to highly toxic to mussels and algae, highlighting the need for a better understanding of the overall impact of plastic-associated chemicals on aquatic ecosystems.

Controlled, photocatalytic C-H bond activations are key reactions in the toolkits of the modern synthetic chemist. While it is known that the uranyl(VI) ion, [(UO2)-O-VI](2+), the environmentally dominant form of uranium, is photoactive, most literature examines its luminescent properties, neglecting its potential synthetic utility for photocatalytic C-H bond cleavage. Here, we synthesise and fully characterise an air-stable and hydrocarbon-soluble uranyl phenanthroline complex, [(UO2)-O-VI(NO3)(2)(Ph(2)phen)], U-Ph2phen, and demonstrate that it can catalytically abstract hydrogen atoms from a variety of organic substrates under visible light irradiation. We show that the commercially available parent complex, uranyl nitrate ([(UO2)-O-VI(NO3)(2)(OH2)(2)]center dot 4H(2)O; U-NO3), is also competent, but from electronic spectroscopy we attribute the higher rates and selectivity of U-Ph2phen to ligand-mediated electronic effects. Ketones are selectively formed over other oxygenated products (alcohols, etc.), and the catalytic oxidation of substrates containing a benzylic C-H position is particularly improved for U-Ph2phen. We also show uranyl-mediated photocatalytic C-C bond cleavage in a model lignin compound for the first time.

We previously described a pH-sensitive phosphoramidate linker scaffold that can be tuned to release amine-containing drugs at various pH values. In these previous studies it was determined that the tunability of this linker was dependent upon the proximity of an acidic group (e.g., carboxylic acid or pyridinium). In this study, we confirmed that the tunability of pH-triggered amine-release was also dependent upon the pK(a) of the proximal acidic group. A series of 2-carboxybenzyl phosphoramidates was prepared in which the pK(a) of the proximal benzoic acid was predictably attenuated by substituents on the benzoate ring consistent with their sigma-values.

Cnidium officinale Makino is an important medicinal plant of oriental clinics and is considered as the main source of phthalides, polyphenols, and flavonoids. However, there is no available report regarding the effect of different light colors on the secondary metabolites composition of C. officinale. In this study different light (dark, white, blue, red and red: blue) conditions were arranged to raise callus on MS medium containing 0.5 mg.L-1 of each 2,4-D and BAP. Callus grown in dark condition showed maximum (2.0 g) fresh weight with lower total phenolic and flavonoids contents. Also, in dark condition callus faced higher catalase (CAT) and guaiacol peroxidase (GPX) activities to avoid free radicals. Mix (red: blue) light condition favored the synthesis of phenolics and flavonoids in callus at the cost of higher ascorbate peroxidase (APX) and superoxide dismutase (SOD) enzymes expression. However, DPPH free radical scavenging activity was less variable among the samples from the different light conditions. Interestingly, the HPLC profile showed higher (28.3 mu g.g(-1) DW) phthalide accumulation in dark grown-cultures. Compared to other light conditions, 3-butyledinephthalide accumulation was higher (0.43 mu g-g(-1) DW) in white light-grown callus. These findings suggest that light conditions play an important role in the regulation of in vitro callus growth and synthesis of important medicinal compounds of C. officinale.

Application In Synthesis of Isobenzofuran-1(3H)-one. I found the field of Pharmacology & Pharmacy very interesting. Saw the article Phthalide derivative CD21 alleviates cerebral ischemia-induced neuroinflammation: Involvement of microglial M2 polarization via AMPK activation published in 2020, Reprint Addresses Du, JR (corresponding author), Sichuan Univ, Dept Pharmacol, Chengdu, Peoples R China..

Microglia can be activated to become the classic phenotype (M1) or alternative phenotype (M2), which play an important role in regulating neuroinflammatory response and tissue repair after ischemic stroke. CD21, a novel phthalide derivative, is a potential neuroprotectant against ischemic brain injury. The present study further investigated the effects of CD21 on post-ischemic microglial polarization and the underlying mechanisms. Transient middle cerebral artery occlusion (tMCAO) was used as a mouse model of ischemic stroke, while BV2 cells stimulated with conditioned medium collected from oxygen-glucose deprivation-treated HT22 cells were used in in vitro ischemic studies. The current results showed that CD21 dose-dependently and significantly improved neurological outcomes in tMCAO mice. Biochemical analyses revealed that CD21 decreased the expression of M1 phenotype markers (CD86, interleukin-1 beta and inducible nitric oxide synthase) and increased the expression of M2 phenotype markers (CD206, interleukin-10 and YM1/2) in both ischemic brain tissues and BV2 cells. Meanwhile, CD21 decreased the production of proinflammatory cytokines (interleukin-1 beta, interleukin-6 and tumor necrosis factor-alpha), promoted the release of the antiinflammatory cytokine (interleukin-10), and enhanced the phosphorylation of adenosine 5′-monophosphate-activated protein kinase (AMPK) in ischemic brain tissue and BV2 cells. Furthermore, the AMPK inhibitor (compound C) reversed these effects of CD21 in BV2 cells. These findings indicate that CD21 alleviates post-ischemic neuroinflammation through induction of microglial M2 polarization that is at least in part medicated by AMPK activation, suggesting that CD21 may be a promising candidate for protecting against ischemic brain injury.
