Simultaneously achieving excellent mechanical properties and superior gas separation performance remains a great challenge for thermally rearranged polymers when applied as the membrane materials in large scale gas separation applications. Herein, different heteroaromatic non-TR-able codiamines containing benzimidazole/benzoxazole structures were incorporated into ortho-hydroxyl functionalized polyimide backbones, which were subsequently transformed into the poly(benzoxazole-co-polyimide) copolymers by thermal rearrangement (TR). In all cases, the solid-state TR reaction induces the increased preferential intersegmental distances (d-spacing) and fractional free volumes of polymer chains, favorable for the gas permeation. While, the pi-pi stacking distance exhibits opposite variation tendencies for benzimidazole-based and benzoxazole-based TR-PBOI membranes, which is demonstrated to make a significant effect on the gas selectivity. These TR-PBOI membranes thermally treated at 420 degrees C for 1 h exhibit higher tensile properties in relative to most of previously reported TR-PBOI membranes with the tensile strength of 97-118 MPa and initial modulus of 2.0-2.4 GPa. Moreover, incorporating heteroaromatic non-TR-able codiamines endows the resultant TR-PBOI membranes with excellent gas separation properties for the CO2/CH4 gas pairs with the CO2 permeability and CO2/CH4 ideal selectivity values exceeding the 1991 upper bound and close to 2008 upper bound. We anticipate this facile method will facilitate the large-scale preparation and application of TR membranes for gas separation.

The main research directions are chemical synthesis, new energy materials, preparation and modification of special coatings. 363-72-4, Name is Pentafluorobenzene, molecular formula is C6HF5, belongs to benzoxazole compound. In a document, author is Singh, Varinder, HPLC of Formula: https://www.ambeed.com/products/363-72-4.html.

A novel series of benzoxazolyl linked benzylidene based rhodanine and their cyclic analogs were synthesized, characterized and evaluated for their alpha-amyloglucosidase inhibitory activity. Out of eight target compounds, two compounds (4b and 5b) displayed potent inhibitory activity against alpha-amyloglucosidase with IC50 values in the range of 0.24 +/- 0.01-0.94 +/- 0.01 A mu M as compared to standard drug acarbose. Among all the tested compounds, compound 5b containing rhodanine at 3-position of phenyl was found to be the most active inhibitor of alpha-amyloglucosidase. Docking studies showed the existence of potential H-bonding interactions between synthesized compounds and alpha-glucosidase which might be responsible for good biological activity.

The π-electrons of these planar compounds are free to cycle around the circular arrangements of atoms found in the aromatic moieties. This stems from the resonance found in planar ring systems, like benzene, and C6HF5. HPLC of Formula: https://www.ambeed.com/products/363-72-4.html.

The present report is based on straightforward synthesis of molecular palladium complexes of benzothiazole based bulky ligands. Catalytic potential of 1 [Pd(L1)(2)Cl-2] and 2 [Pd(L2)(2)Cl-2] has been screened for Suzuki coupling. Due to structural difference between 1 and 2 (anthracen-9-yl in 1, and pyren-1-yl in 2), they behave as designers pre-catalysts and show different catalytic behaviour and nature by dispensing the nanoparticles of different materials (PdS by 1 and Pd16S7 by 2). This is an unprecedented observation as the size of the aryl substituent controls the efficiency (efficiency: 1 > 2) through determining the composition and nature of insitu generated nanoparticles.

New month, new HOT articles! We are pleased to share a selection of our referee-recommended HOT articles in 2021. We hope you enjoy reading these articles. Quality Control of Pentafluorobenzene, Name is Pentafluorobenzene, molecular formula is C6HF5, molecular weight is 168.0642, MDL number is MFCD00000286, category is benzoxazole. Now introduce a scientific discovery about this category.

Based on benzoxazole and benzothiazole scaffold as an important pharmacophore, two series of 2-(aryloxymethyl) benzoxazole and benzothiazole derivatives were synthesized and their antifungal effects against eight phytopathogenic fungi were evaluated. Compounds 5a, 5b, 5h, and 5i exhibited significant antifungal activities against most of the pathogens tested. Especially 5a, 5b, 5h, 5i, 5j, and 6h inhibited the growth of F. solani with IC50 of 4.34-17.61 mu g/mL, which were stronger than that of the positive control, hymexazol (IC50 of 38.92 mu g/mL). 5h was the most potent inhibitor (IC50 of 4.34 mu/mL) against F. Solani, which was about nine times more potent than hymexazol. Most of the test compounds displayed significant antifungal effects against B. cinerea (IC50 of 19.92-77.41 mu g/mL), among them, 5a was the best one (IC50 of 19.92 mu g/mL). The structure-activity relationships (SARs) were compared and analyzed. The result indicates that the electron-drawing ability and position of the substituents have a significant impact on biological activities. Furthermore, docking studies were carried out on the lipid transfer protein sec14p from S. cerevisiae, and preliminarily verified the antifungal activities. Taken together, these results provide 2-(phenoxymethyl)benzo[d]oxazole as an encouraging framework that could lead to the development of potent novel antifungal agents.

A copper-catalyzed isothiocyanation of amines with sodium bromodifluoroacetate and sulfur in the absence of organophosphine has been established. This approach represents a simple and efficient one-pot synthesis of isothiocyanates, and features excellent functional group tolerance and the use of a cheap, safe and odorless sulfur source. Moreover, this process could directly provide isothiocyanate analogous bioactive molecules, thiocarbonyl-containing pesticides and facile construction of benzoxazole and benzimidazole frames.

Benzothiazole derivatives were used as models to study the excited-state intramolecular proton transfer (ESIPT) from an experimental and theoretical point of view. The experimental electronic and vibrational results were compared with a comprehensive selection of state-of-the-art computational methods in a workflow approach. The latter were performed based on modern techniques, such as DLPNO-CCSD(T), which gives the reference energies and current methodologies for ESIPT analysis, such as molecular dynamics and charge density difference testing. The theoretical vibrational results were focused on the stretch vibrational-mode of the hydroxyl group, which indicated a large increase in the intramolecular hydrogen bond strength, which facilitates the ESIPT process. Theoretically, the optimization of a large number of molecules shows that pi-stacking plays a fundamental role in benzothiazole stabilization, with a remarkably strong intramolecular hydrogen bond. The potential energy surface of the ESIPT reactive benzothiazole (4HBS) has a clear transition state where ESIPT is easily observed with a large difference in energy between the enol and keto tautomer. Additionally, molecular dynamics showed that the ESIPT process occurs very fast. The tautomer appears around 8.7 fs and the enolic form is regenerated in just 24 fs, closing the Forster cycle. The calculated Stokes shift could be related to the ESIPT process and the experimental solid-state emission spectrum matched almost perfectly with the theoretical one. In contrast, for the non-ESIPT benzothiazole (4HBSN), the agreement between theory and experiment was limited, probably due to intermolecular interaction effects that are not considered in these calculations.

A one-pot, three-component reaction between alkyl 1-chlorocyclopropanecarboxylate, alkyne diester, and amine is developed. This cascade reaction proceeds smoothly to afford substituted 2-aminophenols in high yields. The process proceeds through a formal [3 + 3] cycloaddition between an enamine and a cyclopropene intermediate formed in situ. The substituted 2-aminophenols can be transformed into phenoxazines and benzoxazole derivatives with the treatment of PIDA.

Tuberculosis (TB) is one of the major contagious diseases with high mortality which is caused by Mycobacterium tuberculosis (Mtb) pathogen. Due to the existing antibiotic resistance (MDR-TB) to tuberculosis, the demand for the development of new potential chemotherapy drugs is increasing. Herein, we report synthesis of two novel benzoxazole-based series, namely 2-phenyl benzoxazole sulfonamide and 2-piperidine-benzoxazole sulfonamides. These compounds were evaluated for their antimycobacterial activity against Mycobacterium tuberculosis H37Rv strain, using the microplate alamarBlue assay. Molecular docking studies were carried out to comprehend the binding mode of the compounds. It is evident from molecular docking studies and minimum inhibitory concentration assay (MIC) that 2-phenyl benzoxazole sulfonamide scaffold has a greater potential of antitubercular activity possibly by ENR inhibition (inhA inhibitors). In silico cytotoxicity studies using CLC-Pred tool database suggested that both the series were relatively safe. [GRAPHICS]

Folates are essential biomolecules required to carry out many crucial processes in leishmania parasite. Dihydrofolate reductase-thymidylate synthase (DHFR-TS) and pteridine reductase 1 (PTR1) involved in folate biosynthesis in leishmania have been established as suitable targets for development of chemotherapy against leishmaniasis. In the present study, various computational tools such as homology modelling, pharmacophore modelling, docking, molecular dynamics and molecular mechanics have been employed to design dual DHFR-TS and PTR1 inhibitors. Two designed molecules, i.e. 2-(4-((4-nitrobenzyl)oxy)phenyl)-1H-benzo[d]imidazole and 2-(4-((2,4-dichlorobenzyl)oxy)phenyl)-1H-benzo[d]oxazolemolecules were synthesized. MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay was performed to evaluate in vitro activity of molecules against promastigote form of Leishmania donovani using Miltefosine as standard. 2-(4-((4-nitrobenzyl)oxy)phenyl)-1H-benzo[d]imidazole and 2-(4-((2,4-dichlorobenzyl)oxy)phenyl)-1H-benzo[d]oxazolemolecules were found to be moderately active with showed IC50 = 68 +/- 2.8 mu M and 57 +/- 4.2 mu M, respectively.
