The chromogenic properties of 2-(2-carbomethoxy-3,4-dichloro-6-hydroxyphenyl)benzoxazole (1) were studied. Solvatochromism of 1 was observed at keto-enol equilibrium due to the ground state intramolecular proton transfer (GSIPT). It was found that solvents with a good hydrogen bond acceptor (beta) ability were able to stabilise the keto form of 1. The excited-state intra molecular proton transfer (ESIPT) in molecules of 1 resulted in intense fluorescence with an anomalous Stokes shift of up to 8493 cm 1 and quantum yields of 0.08-0.19. The keto-form of 1 exhibits negative T-type photochromism with a thermally reversible photoconversion to the enol form. The complexes of ligand 1 with Zn(II) and Cd(II) were synthesised. According to X-ray structural analysis, the zinc complex is the neutral complex, which is formed by two oxazole-N and two phenol O donors of ligand 1 which crystallise in a centrosymmetric group with the zinc ion located on the inversion centres. The synthesised complexes possess effective blue fluorescence and resistance to photodegradation.

Background: Receptor Tyrosine Kinases (RTK) are the main family of cell surface receptors for growth factors, hormones and cytokines which are responsible for cell growth and differentiation and are considered as an important therapeutic target in cancer. Objective: The aim of this study was to design, synthesise and conduct the biological evaluation of benzimidazole/benzoxazole substituted triazolotriazines as new anticancer agents. Methods: A series of benzimidazolyl and benzoxazolyl-linked triazolotriazines 8a-e and 9a-e were synthesized as receptor tyrosine kinase inhibitors. Target compounds were evaluated in HGF-induced cell proliferation assay in A549, MCF-7, HepG2 and MDA-MB-231 cancer cells. Results: Hepatocellular carcinoma was the most sensitive cell line towards the tested compounds and 8e was the most potent one on HepG2 cells with an IC50 value of 5.13 mu M which was close to crizotinib (HepG2 IC50 = 4.35 mu M) as a standard c-Met kinase inhibitor. c-Met kinase assay of 8e showed that this compound is not capable of inhibiting this enzyme and subsequently molecular docking confirmed the low affinity of 8e towards cMet active site and its possible anticancer mechanism through VEGFR-2 inhibition. Conclusion: Further in silico predictions revealed that 8e can be a drug candidate with favorable pharmacokinetic properties.

New Advances in Chemical Research in 2021. Catalysts are in the same phase as the reactants. Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 367-11-3, Name is 1,2-Difluorobenzene, molecular formula is , belongs to benzoxazole compound. In a document, author is Peng, Jiang, COA of Formula: https://www.ambeed.com/products/367-11-3.html.

New diarylethene derivatives containing benzoxazole (NBO) and benzothiazole (NBT) have been synthesized. Light-induced trans-cis isomerization of NBO and NBT took place in crystals, and only induced the needle-like crystals of NBO to bend backwards away from the UV light source. The movement of the atoms was deemed to take place during the isomerization of NBO; hence, strain would be produced and accumulated rapidly in the surface of crystals exposed to UV light. The uniform release of strain led to the bending of needle-like crystals. The light-induced trans-cis isomerization efficiency of NBT was too low to drive the motion of crystals, which might have originated from the large repulsion between naphthyl and benzothiazole. These results provide a new platform for the transformation of light energy into mechanical energy in molecular crystals through the unimolecular photochemical reaction of diarylethene derivatives.

New discoveries in chemical research and development in 2021. The transformation of simple hydrocarbons into more complex and valuable products has revolutionised modern synthetic chemistry.

Now introduce a scientific discovery about this category.

In operando observation of reaction intermediates is crucial for unraveling reaction mechanisms. To address the sensitivity limitations of commercial ReactIR, a flow cell was integrated with a Fourier transform infrared (FTIR) spectrometer yielding a flow FTIR device coupled with an NMR spectrometer for the elucidation of reaction mechanisms. The former device detects the low-intensity IR peaks of reaction intermediates by adjusting the path length of the FTIR sample cell, whereas the flow NMR allows the quantitative analysis of reaction species, thus offsetting the limitations of IR spectroscopy resulting from different absorption coefficients of the normal modes. Using the flow NMR and FTIR device, the controversial mechanism of benzoxazole synthesis was conclusively determined by spectroscopic evaluation of the reaction intermediates. This system enabled the accurate acquisition of previously elusive kinetic data, such as the reaction time and rate-determining step. The implementation of reaction flow cells into NMR and FTIR systems could be widely applied to study various reaction mechanisms, including dangerous and harsh reactions, thus avoiding contact with potentially harmful reaction intermediates.

Prion diseases are a group of neurodegenerative and fatal central nervous system disorders. The pathogenic mechanism involves the conversion of cellular priori protein (PrPC) to an altered scrapie isoform (PrPSc), which accumulates in amyloid deposits in the brain. However, no therapeutic drugs have demonstrated efficacy in clinical trials. We previously reported that BMD42-29, a synthetic compound discovered in silico, is a novel anti-prion compound that inhibits the conversion of PrPC to protease K (PK)-resistant PrPSc fragments (PrPres). In the present study. 14 derivatives of BMD42-29 were obtained from BMD42-29 by modifying in the side chain by in silico feedback, with the aim to determine whether they improve anti-priori activity. These derivatives were assessed in a PrPSc-infected cell model and some derivatives were further tested using real time-quaking induced conversion (RT-QuIC). Among them, BMD42-2910 showed high anti-prion activity at low concentrations in vitro and also no toxic effects in a mouse model. Interestingly; abundant PrPres was reduced in brains of mice infected with prion strain when treated with BMD42-2910, and the mice survived longer than control mice and even that treated with BMD42-29. Finally, high binding affinity was predicted in the virtual binding sites (Asn159, Gln 160, Lys194, and Glu196) when PIPC was combined with BMD-42-2910. Our findings showed that BMD42-2910 sufficiently reduces PrPres generation in vitro and in vivo and may be a promising novel anti-prion compound.

7-Borylindoles undergo a one-pot oxidative-hydrolysis of the arylboronate and oxidative cleavage of the indole C2-C3 double bond to afford o-amidophenol derivatives. Subsequent cyclisation delivers benzoxazoles bearing an acyl group at C4, a substitution pattern common to fungal-derived benzoxazole alkaloids. Using 7-borylindoles as substrates to access functionalised o-amidophenols circumvents the difficult preparation of these compounds from arenes, streamlining access to substituted 4-acylbenzoxazoles in the process.

Benzoxazole derivative K313 has previously been reported to possess anti-inflammatory effects in lipopolysaccharide-induced RAW264.7 macrophages. To date, there have been no related reports on the anticancer effects of K313. In this study, we found that K313 reduced the viability of human B-cell leukemia (Nalm-6) and lymphoma (Daudi) cells in a dose-dependent manner without affecting healthy peripheral blood mononuclear cells (PBMCs) and induced moderate cell cycle arrest at the G0/G1 phase. Meanwhile, K313 mediated cell apoptosis, which was accompanied by the activation of caspase-9, caspase-3, and poly ADP-ribose polymerase (PARP). Furthermore, cells treated with K313 showed a significant decrease in mitochondrial membrane potential (MMP), which may have been caused by the caspase-8-mediated cleavage of Bid, as detected by Western blot analysis. We also found that K313 led to the downregulation of p-p70S6K protein, which plays an important role in cell survival and cell cycle progression. In addition, treatment of these cells with K313 blocked autophagic flux, as reflected in the accumulation of LC3-II and p62 protein levels in a dose- and time-dependent manner. In conclusion, K313 decreases cell viability without affecting normal healthy PBMCs, induces cell cycle arrest and apoptosis, reduces p-p70S6K protein levels, and mediates strong autophagy inhibition. Therefore, K313 and its derivatives could be developed as potential anticancer drugs or autophagy blockers in the future.
