The insect enzyme GH20 beta-N-acetyl-D-hexosaminidase OfHex1 represents an important chitinolytic enzyme found in the agricultural pest Ostrinia furnacalis (Guenee) and inhibition of this enzyme has been considered a promising strategy for the development of eco-friendly pesticides. In this article, based on the structure of the catalytic domains of OfHex1, a series of novel glycosyl triazoles were designed and synthesized via Cu-catalyzed azide-alkyne [3+ 2] cycloaddition reaction. To investigate the potency and selectivity of these glycosyl triazoles, the inhibition activities towards OfHex1 and HsHexB (human beta-N-acetylhexosaminidase B) were studied. Particularly compound 17c (OfHex1, K-i= 28.68 mu M; HsHexB, K-i > 100 mu M) exhibited a suitable activity and selectivity against OfHex1. Furthermore, the possible inhibitory mechanisms of 17c with OfHex1 were studied using molecular docking and MD simulations. The structure-activity relationship results as well as the formed binding patterns may provide promising insights into the further development of novel OfHex1 inhibitors.

The Ni-catalyzed N-arylation of beta-fluoroalkylamines with broad scope is reported for the first time. Use of the air-stable pre-catalyst (PAd2-DalPhos)Ni(o-tol)Cl allows for reactions to be conducted at room temperature (25 degrees C, NaOtBu), or by use of a commercially available dual-base system (100 degrees C, DBU/NaOTf), to circumvent decomposition of the N-(beta-fluoroalkyl)aniline product. The mild protocols disclosed herein feature broad (hetero)aryl (pseudo)halide scope (X=Cl, Br, I, and for the first time phenol-derived electrophiles), encompassing base-sensitive substrates and enantioretentive transformations, in a manner that is unmatched by any previously reported catalyst system.

Octahedral CdS-ZnS composites were synthesized using a simple method of cation exchange and hydrothermal treatment, using Cd-3(C3N3S3)(2) (denoted as Cd-3(TMT)(2)) as a precursor and Zn2+ for ion exchange. In the spontaneous ion exchange process, there is the formation of compact heterojunctions and three-dimensional octahedral structures. By controlling the ion exchange level, the composition of (CdxZn1-x)(3) (TMT)(2) hybrid nanomaterials can be regulated, and the composite can be used as a template to generate octahedral CdS-ZnS. Photocatalytic oxidation of toluene to benzaldehyde was used as a model reaction to evaluate the performance of the as-prepared samples, and the CZ-2 catalyst shows the highest photocatalytic activity, giving a benzaldehyde formation rate of 1078 mu mol.g(-1).h(-1) without the need of any solvent. The excellent performance is ascribed to the octahedral structure which is large in specific surface area and compact in heterojunctions. It is envisaged that the method is suitable for the generation of heterojunctions for photocatalytic purposes.

One-pot synthesis of furan-2,5-dimethylcarboxylate (FDMC) from 5-hydroxymethylfurfural (HMF) is highly demanding for the commercial production of polyethylene furanoate (PEF). Herein, a direct synthesis of FDMC is reported from oxidative esterification of HMF using ultrafine CuO particles dispersed on nitrogen-doped hollow carbon nanospheres (CuO/N-C-HNSs) as a catalyst and tert-butyl hydroperoxide (TBHP) as an oxidizing and methylating reagent. The CuO/N-C-HNSs was prepared through a template protection-sacrifice strategy using SiO2 as a sacrificial template and histidine as the precursor for N and C. N-doping facilitated a strong interaction between the support and copper species, affording formation of CuO nanoparticles of less than 10 nm in size. By virtue of the highly dispersed CuO nanoparticles and a high BET surface area 373 m(2)/g, the CuO/N-C-HNSsshows excellent catalytic performance in the selective conversion of HMF into FDMC affording 93 % yield of the desired product with a TON value of 49. Furthermore, the oxidative esterification involving (SPC)-C-3-H bond functionalization is also demonstrated using the same catalyst.

We report the catalytic reduction of both active esters and amides by selective C(acyl)-X (X=O, N) cleavage to access aldehyde functionality via a palladium-catalyzed strategy. Reactions are promoted by hydrosilanes as reducing reagents with good to excellent yields and with excellent chemoselectivity for C(acyl)-N and C(acyl)-O bond cleavage. Carboxylic acid C(acyl)-O bonds are activated by 2-chloro-4,6-dimethoxy-1,3,5-triazine (CDMT) to form triazine ester intermediates, which further react with hydrosilanes to yield aldehydes in one-pot two-step procedures. We demonstrate that C(acyl)-O cleavage/formylation offers higher yields and broader substrate scopes compared with C(acyl)-N cleavage under the same reaction conditions.

The combination of commonly used FeCl3/SIPr with Ti(OEt)(4)/PhOM enabled a highly general iron- based catalyst system, which could efficiently catalyze the biaryl coupling reaction between various electrophiles (I, Br, Cl, OTs, OCONMe2, OSO2NMe2) and common or functionalized aryl Grignard reagents with high functional group tolerance. Selective couplings of aryl iodides and bromides over the corresponding oxygen-based electrophiles have been achieved, and thus a terphenyl acid intermediate for anidulafungin was conveniently synthesized via an orthogonal coupling strategy.

Ln(NO3)(3)center dot nH(2)O reacted with 2,4-dichlorobenzoic acid (2,4-HDCB) and NaOH under solvothermal conditions of water and ethanol to yield four lanthanide-organic coordination polymers (CPs) [Eu(2,4-DCB)(3)(CH3CH2OH)(2)] (1) and [Ln(2,4-DCB)(3)(H2O)] [Ln = Gd (2), Tb (3), Dy (4)]. The second ligand 4,4′-bipyridine (4,4′-bpy) was introduced into the above reaction systems to provide four new lanthanide-organic CPs [Ln(2)(2,4-DCB)(6)(4,4′-bpy)(H2O)(2)] [Ln = Eu (5), Gd (6), Tb (7), Dy (8)]. Single-crystal and powder X-ray diffraction analyses reveal that CPs 1 and 2 possess similar one-dimensional (1D) structures, and CPs 2-4 and 5-8 are isostructural, respectively. In 1-4, the 2,4-DCB anions bridge the Ln(III) ions to form a 1D chain. In 5-8, six 2,4-DCB anions link two Ln(III) ions into a binuclear Ln(2)(2,4-DCB)(6) unit, and the Ln(2)(2,4-DCB)(6) units are further connected by the 4,4′-bpy co-ligands to generate a 1D chain. The photoluminescent and magnetic properties of 1-8 were investigated.

I found the field of Archaeology; Art; Chemistry; Spectroscopy very interesting. Saw the article Crystalline Deposits in New Display Cases at the Rijksmuseum: Characterisation and Origin published in 2021. HPLC of Formula: C7H4Cl2O2, Reprint Addresses van Iperen, J (corresponding author), Rijksmuseum, Conservat & Sci Dept, Museumstr 1,Postbus 74888, NL-1070 DN Amsterdam, Netherlands.. The CAS is 50-84-0. Through research, I have a further understanding and discovery of 2,4-Dichlorobenzoic acid

An unusual phenomenon occurred in new display cases at the Rijksmuseum four months after their installation in April 2013. White deposits were visible on glass windows, silicone door gaskets, black structural adhesive seals, and on works of art. The works of art most affected by these deposits were bronze sculptures, wooden and waxed objects, tempera, and oil paintings. In this study the deposits were chemically characterised using (pyrolysis-)gas chromatography-mass spectrometry ((Py-)GC-MS), mu-Raman spectroscopy (mu-Raman), ion chromatography (IC), and scanning electron microscopy combined with energy dispersive X-ray spectroscopy (SEM-EDX). Five chemically different crystalline deposits were found. They were identified as organic salts of the base 2,2,6,6-tetramethyl-4-piperidinol (TMP-ol), a secondary amine, and five different carboxylic acids. It was found that TMP-ol, which is part of the UV-light stabiliser Tinuvin-770, emitted from the structural adhesive Terostat-9220. Terostat-9220 was used in large quantities in the display cases to adhere glass windows to metal parts. The carboxylic acids derived from both construction materials used to build the cases and from conservation materials present on the exhibited works of art. The carboxylic acids involved were 2,4-dichlorobenzoic acid, formic acid, methacrylic acid, palmitic acid, and an unknown carboxylic acid, respectively emitted from peroxide-cured silicone gaskets, panels of medium-density fibreboard (MDF), UV-adhesive, beeswax containing products, and from an unknown acidic conservation product or binding medium. The identification of the crystalline deposits was supported by their syntheses in the laboratory. Since 2013, similar deposits have been observed in a number of museum collections worldwide. A treatment for preventing further growth of the deposits was developed and applied in the Rijksmuseum showcases.

The Name is 2,4-Dichlorobenzoic acid. Through research, I have a further understanding and discovery of 50-84-0.

N-benzhydrylpiperazine and 1,3,4-oxadiazoles are pharmacologically active scaffolds which exhibits significant inhibitory growth effects against various cancer cells, however, antiproliferation effects and the underlying mechanism for inducing apoptosis for aforementioned scaffolds addressing HeLa cancer cells remains uncertain. In this study, N-benzhydrylpiperazine clubbed with 1,3,4-oxadiazoles (4a-4h) were synthesized, subsequently characterized using high resolution spectroscopic techniques and eventually evaluated for their antiproliferation potential by inducing apoptosis in HeLa cancer cells. The MTT assay screening results revealed that among all, compound 4d (N-benzhydryl-4-((5-(4-aminophenyl)-1,3,4-oxadiazol-2-yl)methyl)piperazine) in particular, exhibited IC (50) value of 28.13 +/- 0.21g/mL and significantly inhibited the proliferation of HeLa cancer cells in concentration-dependent manner. The in vitro anticancer assays for treated HeLa cells resulted in alterations in the cell morphology, reduction in colony formation, and inhibition of cell migration in concentration-dependent treatment. Furthermore, G2/M phase arrest, variations in the nuclear morphology, degradation of chromosomal DNA confirmed the ongoing apoptosis in treated HeLa cells. Increase in the expression of cytochrome C and caspase-3 confirmed the involvement of intrinsic mitochondrial pathway regulating the cell death. Also, elevation in reactive oxygen species level and loss of mitochondrial membrane potential signified that compound 4d induced apoptosis in HeLa cells by generating the oxidative stress. Therefore, compound 4d may act as a potent chemotherapeutic agent against human cervical cancer.
