Mild and efficient palladium-catalyzed direct trifluoroethylation of aromatic systems by C-H activation

The introduction of trifluoroalkyl groups into aromatic molecules is an important transformation in the field of organic and medicinal chemistry. However, the direct installation of fluoroalkyl groups onto aromatic molecules still represents a challenging and highly demanding synthetic task. Herein, a simple trifluoroethylation process that relies on the palladium-catalyzed C-H activation of aromatic compounds is described. With the utilization of a highly active trifluoroethyl(mesityl)iodonium salt, the developed catalytic method enables the first highly efficient and selective trifluoroethylation of aromatic compounds. The robust catalytic procedure provides the desired products in up to 95 % yield at 25 C in 1.5 to 3 hours and tolerates a broad range of functional groups. The utilization of hypervalent reagents opens new synthetic possibilities for direct alkylations and fluoroalkylations in the field of transition-metal-catalyzed C-H activation.

The synthesis and structure-activity relationship studies of selective acetyl-CoA carboxylase inhibitors containing 4-(thiazol-5-yl)but-3-yn-2-amino motif: Polar region modifications

The structure-activity relationship study focused on the polar region of the HTS hit A-80040 (1) producing several series of potent and selective ACC2 inhibitors. The SAR suggests a compact lipophilic pocket that does not tolerate polar and ionic groups. Replacement of the hydroxyurea group with isoxazoles improves ACC2 selectivity while maintaining potency. Variations at the propargylic site of 11a reduce ACC2 potency.

Structure-based virtual screening and optimization of modulators targeting Hsp90-Cdc37 interaction

Identification of novel Hsp90 inhibitors to disrupt Hsp90-Cdc37 protein-protein interaction (PPI) could be an alternative strategy to achieve Hsp90 inhibition. In this paper, a series of small molecules targeting Hsp90-Cdc37 complex are addressed and characterized. The molecules’ key characters are determined by utilizing a structure-based virtual screening workflow, derivatives synthesis, and biological evaluation. Structural optimization and structure?activity relationship (SAR) analysis were then carried out on the virtual hit of VS-8 with potent activity, which resulted in the discovery of compound 10 as a more potent regulator of Hsp90-Cdc37 interaction with a promising inhibitory effect (IC50?=?27?muM), a moderate binding capacity (KD?=?40?muM) and a preferable antiproliferative activity against several cancer lines including MCF-7, SKBR3 and A549?cell lines (IC50?=?26?muM, 15?muM and 38?muM respectively). All the data suggest that compound 10 exhibits moderate inhibitory effect on Hsp90-Cdc37 and could be regard as a first evidence of a non-natural compound targeting Hsp90-Cdc37 PPI.

Non-activated peroxymonosulfate oxidation of sulfonamide antibiotics in water: Kinetics, mechanisms, and implications for water treatment

Despite that sulfate radical-based activated peroxymonosulfate (PMS) oxidation processes (e.g., UV/PMS, Co2+/PMS, etc.) have been widely applied for decontamination, the direct oxidation of organic contaminants by PMS per se is less known. This contribution reports that certain contaminants, such as sulfonamides (SAs), are amendable to direct oxidation by PMS without activation. Using sulfamethoxazole (SMX) as a representative, kinetics and density functional theory (DFT)-based computational methods were applied to elucidate the underlying mechanisms and pathways through which SMX was transformed by direct PMS oxidation. High resolution mass spectrometry (HR-MS) coupled with high performance liquid chromatography (HPLC) analyses using authentic standards were adopted to qualifying and quantifying SMX transformation products. Our results reveal that nonradical oxidation of SMX by PMS was initiated by formation of a transition state complex between PMS molecule and amino functional group of SMX. Such reaction was assisted by two water molecules, which significantly reduced energy barrier. Direct PMS oxidation of SMX led to the formation of N4-hydroxyl-sulfamethoxazole (N4-OH-SMX), 4-nitroso-sulfamethoxazole (4-NO-SMX), and 4-nitro-sulfamethoxazole (4-NO2-SMX), sequentially. Implications of PMS oxidation with SAs to water treatment were further evaluated by investigating the effects of PMS dosage, pH, and natural water matrices. While PMS has a potential to transform a suite of SAs with similar structures (SMX, sulfisoxazole, sulfamethizole, sulfapyridine, sulfadiazine, and sulfachloropyridazine), the formation of potential hazardous nitroso- and nitro-byproducts should be scrutinized before this technology can be safely used for water and wastewater treatment.

New tricks of well-known aminoazoles in isocyanide-based multicomponent reactions and antibacterial activity of the compounds synthesized

The well-known aminoazoles, 3-amino-5-methylisoxazole and 5-amino-N-aryl-1H-pyrazole-4-carboxamides, were studied as an amine component in Ugi and Groebke-Blackburn-Bienayme multicomponent reactions. The first example of an application of aminoazoles in an Ugi four-component reaction was discovered and novel features of a Groebke-Blackburn-Bienayme cyclocondensation are established and discussed. The heterocycles obtained were evaluated for their antibacterial activity and several of them demonstrated a weak antimicrobial effect, but for most of the compounds a 30-50% increase in biomass of Gram-positive strains (mainly B. subtilis) compared to control was observed.

Enhanced degradation of sulfamethoxazole antibiotic from aqueous solution using Mn-WO3/LED photocatalytic process: Kinetic, mechanism, degradation pathway and toxicity reduction

This study was aimed to explore of the photocatalytic degradation and mineralization of sulfamethoxazole (SMX) by a Mn-WO3/LED process in an LED photoreactor. The effects of operational parameters such as catalyst dosage, pH, initial SMX concentration and reaction time on the efficiency of Mn-WO3/LED process was investigated. Toxicity assays were also performed with both raw and treated SMX solutions by Daphnia Magna. The Mn-WO3 nanoparticle was characterized by various analytical procedures including XRD, FESEM, TEM, FTIR, BET and TGA. In addition, complete degradation of SMX was achieved at solution pH of 6, photocatalyst dosage of 2.3 g L?1 and reaction time of 70 min. Decomposition mechanism indicated that the remarkable ability of HO? free radicals was the main factor responsible for degradation of SMX in the Mn-WO3 process under LED irradiation. The mineralization of SMX in optimal conditions reached to 63% and 85% within 90 and 180 min, respectively. The presence of main anions in water did not considerably influence on the SMX decomposition. Moreover, degradation intermediates of SMX were finally turn up to simple substances such as maleic and oxalic acids. The toxicity analysis showed that the treated SMX aqueous sample was significantly reduced compared to the raw solution. The electrical energy per order (EEO) indicated that energy consumption in the studied process was lower than that in other studies. Therefore, the Mn-WO3 process with LED photoreactor is an emerging, cost-effective and attainable process which can be successfully applied to degrade and mineralize the medical drugs such as SMX.

Reduction of nitrogen-oxygen containing compounds (NOCs) by surface-associated Fe(II) and comparison with soluble Fe(II) complexes

Both Fe(II) adsorbed onto mineral surfaces and soluble Fe(II) complexes are important natural reductants; however, no research has directly compared their reaction kinetics and mechanisms. In this work, the reduction kinetics of heterogeneous Fe(II)-goethite versus homogeneous Fe(II)-tiron were compared for the first time toward thirteen structurally diverse nitrogen-oxygen containing compounds (NOCs). The reduction of NOCs followed pseudo-first-order reaction kinetics in Fe(II)-goethite, with the rate constant k varying over a wide range from 8.56 h?1 to <0.0001 h?1. In electrochemical experiments where NOCs were physically separated from Fe(II)-goethite, k of carbadox was 3.6 times greater than that of a structurally similar compound that cannot complex with surface Fe(II), while such difference in batch reactors was 531 times. Similar differences in the reactivity of NOCs between the two reactors were reported for Fe(II)-tiron. The good linear cross correlations between the reactivity of Fe(II)-goethite and that of Fe(II)-tiron toward NOCs, nitroaromatics, and polyhalogenated compounds (R2 = 0.76?0.94) can be used to predict the reactivity of other structurally related compounds by both reductants. On the basis of the FTIR and UV spectra, surface complexation was further inferred; both the amino functional groups and the pyridine ring were involved in the complexation, with the ring-N more strongly involved than the ring-O. As opposed to the large differences observed in the reactivity of the two Fe(II) reductants, similar reactivity was obtained when an outer-sphere reductant dithionite was employed. Overall, these results show that complexation between certain NOCs and surface-associated Fe(II) existed which facilitated the reduction reaction.

Photo-Fenton oxidation of 3-amino-5-methylisoxazole: a by-product from biological breakdown of some pharmaceutical compounds

The present study aims to assess the removal of 3-amino-5-methylisoxazole (AMI), a recalcitrant by-product resulting from the biological breakdown of some pharmaceuticals, applying a solar photo-Fenton process assisted by ferrioxalate complexes (SPFF) (Fe3+/H2O2/oxalic acid/UVA-Vis) and classical solar photo-Fenton process (SPF) (Fe2+/H2O2/UVA-Vis). The oxidation ability of SPFF was evaluated at different iron/oxalate molar ratios (1:3, 1:6, and 1:9, with [total iron] = 3.58 ¡Á 10?2?mM and [oxalic acid] = 1.07 ¡Á 10?1, 2.14 ¡Á 10?1 and 3.22 ¡Á 10?1?mM, respectively) and pH values (3.5?6.5), using low iron contents (2.0?mg Fe3+ L?1). Additionally, the use of other organic ligands such as citrate and ethylenediamine-N,N?-disuccinic acid (EDDS) was tested. The oxidation power of the classical SPF was assessed at different pH values (2.8?4.0) using 2.0?mg Fe2+ per liter. Furthermore, the effect of AMI concentration (2?20?mg?L?1), presence of inorganic ions (Cl?, SO4 2?, NO3 ?, HCO3 ?, NH4 +), and radical scavengers (sodium azide and D-mannitol) on the SPF method at pH 3.5 was also assessed. Experiments were done using a lab-scale photoreactor with a compound parabolic collector (CPC) under simulated solar radiation. A pilot-scale assay was conducted using the best operation conditions. While at near neutral pH, an iron/oxalate molar ratio of 1:9 led to the removal of 72?% of AMI after 90?min of SPFF, at pH 3.5, an iron/oxalate molar ratio of 1:3 was enough to achieve complete AMI degradation (below the detection limit) after 30?min of reaction. The SPF process at pH 3.5 underwent a slower AMI degradation, reaching total AMI degradation after 40?min of reaction. The scale up of SPF process showed a good reproducibility. Oxalic and oxamic acids were identified as the main low-molecular-weight carboxylic acids detected during the pilot-scale SPF reaction. [Figure not available: see fulltext.]
