Wrobel, Zbigniew published the artcileThe reported formation of 5H-dibenzo [b,e][1,4]diazepin-11( 10H )-ones in the noncatalyzed, base-promoted double arylation of anthranilamide revisited. Correction of some product structures, Category: chlorides-buliding-blocks, the publication is Journal of Heterocyclic Chemistry (2021), 58(9), 1802-1808, database is CAplus.

The base-promoted reaction of 2-halonitro- or 1,2-dihalobenzenes with anthranilamide reported by Cao, Ma et al. (Synthesis2013, 45, 111) was reinvestigated. Some of the products reported, which was identified as dibenzodiazepinones, were actually benzoxazole derivatives In this paper, the correct structures of these products were established and confirmed by independent synthesis. For four other products, the supposed structures were found to be incompatible with the dibenzodiazepinones that were synthesized by the reliable method used.

Apgar, James M. published the artcileIbrexafungerp: An orally active β-1,3-glucan synthesis inhibitor, SDS of cas: 5034-06-0, the publication is Bioorganic & Medicinal Chemistry Letters (2021), 127661, database is CAplus and MEDLINE.

We previously reported medicinal chem. efforts that identified MK-5204 (I), an orally efficacious β-1,3-glucan synthesis inhibitor derived from the natural product enfumafungin. Further extensive optimization of the C2 triazole substituent identified 4-pyridyl as the preferred replacement for the carboxamide of MK-5204, leading to improvements in antifungal activity in the presence of serum, and increased oral exposure. Reoptimizing the aminoether at C3 in the presence of this newly discovered C2 substituent, confirmed that the (R) t-Bu, Me aminoether of MK-5204 provided the best balance of these two key parameters, culminating in the discovery of ibrexafungerp (II), which is currently in phase III clin. trials. Ibrexafungerp displayed significantly improved oral efficacy in murine infection models, making it a superior candidate for clin. development as an oral treatment for Candida and Aspergillus infections.

Apgar, James M. published the artcileMK-5204: An orally active β-1,3-glucan synthesis inhibitor, Synthetic Route of 7080-50-4, the publication is Bioorganic & Medicinal Chemistry Letters (2020), 30(17), 127357, database is CAplus and MEDLINE.

Our previously reported efforts to produce an orally active β-1,3-glucan synthesis inhibitor through the semi-synthetic modification of enfumafungin focused on replacing the C2 acetoxy moiety with an aminotetrazole and the C3 glycoside with a N,N-dimethylaminoether moiety. This work details further optimization of the C2 heterocyclic substituent, which identified 3-carboxamide-1,2,4-triazole as a replacement for the aminotetrazole with comparable antifungal activity. Alkylation of either the carboxamidetriazole at C2 or the aminoether at C3 failed to significantly improve oral efficacy. However, replacement of the iso-Pr α-amino substituent with a t-Bu, improved oral exposure while maintaining antifungal activity. These two structural modifications produced MK-5204, which demonstrated broad spectrum activity against Candida species and robust oral efficacy in a murine model of disseminated Candidiasis without the N-dealkylation liability observed for the previous lead.

Chen, Yiding published the artcileCopper(I)-catalyzed sulfonylative Suzuki-Miyaura cross-coupling, Name: (4-((4-Chlorobenzyl)oxy)phenyl)boronic acid, the publication is Chemical Science (2017), 8(4), 3249-3253, database is CAplus and MEDLINE.

By using a simple copper(I) catalyst a high yielding sulfonylative-Suzuki-Miyaura cross-coupling reaction was developed. The process provided a single step route to diaryl sulfones from the direct combination of arylboronic acids, sulfur dioxide and aryl iodides, and represents the first sulfonylative variant of a classic cross-coupling reaction. Sulfur dioxide was delivered from the surrogate reagent, DABSO. Variation of the reaction conditions allowed interruption of the sulfonylative-Suzuki coupling, resulted in the formation of a presumed Cu-sulfinate intermediate. These sulfinates was trapped as their sodium salts and treated with electrophiles to allow access to arylalkyl sulfones, β-hydroxyl sulfones, sulfonamides and sulfonyl fluorides.

Wei, Xiaoxiao published the artcileFabrication of di-selective adsorption platform based on deep eutectic solvent stabilized magnetic polydopamine: Achieving di-selectivity conversion through adding CaCl₂, HPLC of Formula: 23616-79-7, the publication is Chemical Engineering Journal (Amsterdam, Netherlands) (2021), 421(Part_2), 127815, database is CAplus.

Seeking effective synthesis strategy of adsorbents with di-selective adsorption ability to remove dyes in wastewater is of great significance for solving the increasing environmental problems. Hence, three deep eutectic solvents (DESs) were synthesized and polymerized on the surface of magnetic (Fe3O4) polydopamine (MPDA), in which DES acted as both stabilizer and surface modifier for PDA coating. The fabricated nanoparticles (named as MPDA-PDES) were used as adsorbents for selective adsorption of binary dyes solution Langmuir and Dubinin-Radushkevich isotherm models were suitable to describe adsorption process of malachite green (MG) and sunset yellow FCF (SY) on MPDA-PDES1, resp., indicated that the adsorption of MG was monolayer uptake, and that of SY was phys. adsorption. The effect of solution pH and ionic strength suggested that electrostatic interaction was mainly adsorption driving force. Interestingly, the addition of CaCl₂ in adsorption system realized dynamic transformation from selective adsorption of MG by MPDA-PDES1 to selective adsorption of SY. And selectivity factor reduced from 37.57 to 0.30. MPDA-PDES1 adsorbent possessed excellent anti-interference ability, regeneration and reusability, can be continuously reused six times and adsorption capacity remained basically unchanged. The adsorption of MG-SY from synthetic wastewater manifested that MPDA-PDES1 had unlimited potential for selective removal of target dyes in actual wastewater. Mechanism exploration revealed that MPDA stabilized by DES containing long-chain alkyl groups exhibited better selective adsorption capacity for cationic dyes in binary dyes solutions This was due to the synergistic effect of electrostatic interaction, hydrophobic interaction, hydrogen bonding and π-π stacking between MPDA-PDES1 and dyes. Therefore, proposed DES-based PDA modification strategy improved the stability and reusability of PDA materials, and achieved outstanding selective adsorption ability because of tailorability of DES structure, which provided new ideas for design and synthesis of high-efficiency adsorbents.

Wei, Xiaoxiao published the artcileAdsorption of pharmaceuticals and personal care products by deep eutectic solvents-regulated magnetic metal-organic framework adsorbents, Synthetic Route of 23616-79-7, the publication is Chemical Engineering Journal (Amsterdam, Netherlands) (2020), 124808, database is CAplus.

The ecol. and human health threats brought by emerging pollutants are increasingly serious. Development of efficient removal methods is urgent. Herein, seven deep eutectic solvents (DESs) composed by quaternary ammonium salts and lactic acid or glycolic acid were synthesized and used to regulate magnetic (Fe₃O₄) metal organic framework (MUiO-66-NH₂) composites. The obtained nanoparticles (named as DES-MUiO-66-NH₂) were used as adsorbents to adsorb pharmaceuticals and personal care products (PPCPs). Langmuir isotherm model and pseudo-second-order kinetics model were suitable to analyze the adsorption process of DES-MUiO-66-NH₂ to PPCPs, indicated that the adsorption of PPCPs was chemisorption on homogeneous surface of DES-MUiO-66-NH₂ adsorbents. Under the optimal conditions, the adsorption capacity of DES-MUiO-66-NH₂ toward ofloxacin and mefenamic acid reached up to 97.60 and 79.22 mg/g, resp. Mechanism exploration indicated that DES-MUiO-66-NH₂ selectively adsorbed PPCPs through electrostatic interaction, chelation, π-π stacking, hydrophobic interaction and hydrogen bonding. D. functional theory proved the chelation through theor. calculation Selective experiments manifested that the structures of DESs directly determined the specificity of DES-MUiO-66-NH₂ for different PPCPs, and the investigation of structure-activity relationship provided new ideas for designing efficient tailor-made adsorbents for PPCPs. The proposed PPCPs removal approach focused on the guiding role of DESs in selective adsorption. And this green DESs regulation idea provided more options for the synthesis of high-efficiency and functional adsorbents for emerging pollutants.

Kang, Dongwei published the artcileDiscovery of potent HIV-1 non-nucleoside reverse transcriptase inhibitors by exploring the structure-activity relationship of solvent-exposed regions I, COA of Formula: C9H5ClO4S, the publication is Chemical Biology & Drug Design (2019), 93(4), 430-437, database is CAplus and MEDLINE.

Two novel series of human immunodeficiency virus-1 (HIV-1) non-nucleoside reverse transcriptase inhibitors (NNRTIs) bearing a thiophene[3,2-d]pyrimidine scaffold and sulfonamide linker in the right wing have been identified, which demonstrated activity against the wild-type (WT) HIV-1 strain in MT-4 cells with inhibitory concentrations ranging from micromolar to submicromolar. Especially, against the mutant strains K103N and E138K, most compounds exhibited more potent activity than against WT HIV-1. Compound 7(I) (EC₅₀ = 0.014, 0.031 μM) achieved the most potent activity against the two mutants, being more effective than that of nevirapine (NVP, EC₅₀ = 7.572, 0.190 μM) and comparable to that of etravirine (ETV, EC₅₀ = 0.004, 0.014 μM). Mol. docking experiments on the novel analogs have also suggested that the extensive network of main chain hydrogen bonds are important in the binding mode, which may provide valuable insights for further optimization.

Hydroxylation of aryl carbon-hydrogen bonds with transition metal catalysts has proven challenging when oxygen is used as the oxidant. Here, we report a palladium complex bearing a bidentate pyridine/pyridone ligand that efficiently catalyzes this reaction at ring positions adjacent to carboxylic acids. IR, x-ray, and computational anal. support a possible role of ligand tautomerization from mono-anionic (L,X) to neutral (L,L) coordination in the catalytic cycle of aerobic carbon-hydrogen hydroxylation reaction. The conventional site selectivity dictated by heterocycles is overturned by this catalyst, thus allowing late-stage modification of compounds of pharmaceutical interest at previously inaccessible sites.

Ran, Fen published the artcileNano vanadium nitride incorporated onto interconnected porous carbon via the method of surface-initiated electrochemical mediated ATRP and heat-treatment approach for supercapacitors, Formula: C19H34ClN, the publication is Electrochimica Acta (2017), 405-413, database is CAplus.

A neg. electrode material of nano V nitride/interconnected porous C (Nano-VN/IPC) is fabricated via a novel method combining surface-initiated electrochem. mediated ATRP and heat-treatment process. The structural and composition characterization display that a low crystallinity of VN nanoparticles was obtained, which distributes uniformly in the interconnected pores of the C scaffold materials. The high-distribution of nano-VN particles in the interconnected pores significantly enhances the usage efficiency of the electrochem.-active materials to ensure the high electrochem. performance of the electrode materials. The interconnected pore structure is convenient for diffusion and transfer of electrolyte ions during charging-discharging process. The Nano-VN/IPC electrodes exhibit a high specific capacitance of 284.0 F/g at 0.5 A/g in 2 M KOH aqueous electrolyte with a low resistance and good rate capability. An asym. supercapacitor is assembled with Ni(OH)₂ and Nano-VN/IPC electrodes as the pos. and neg. electrodes. The device presents a high specific capacitance of 122 F/g at the c.d. of 0.5 A/g, and when the c.d. increases to 5 A/g the capacitance still remains 70 F/g. Remarkably, the device delivers an ultrahigh power d. of 35.6 Wh/kg at a power d. of 362.5 W/kg.
