[GRAPHICS] A new chemo-, regio-, and stereoselective cascade reaction features a novel isoxazole –> benzisoxazole rearrangement and affords highly functionalized, differentially protected compounds. The products of this reaction are directly converted to a number of complex, structurally diverse polycyclic molecules. These transformations highlight the unique chemistry inherent to readily prepared fused isoxazoles.

Chemistry, like all the natural sciences, begins with the direct observation of nature— in this case, of matter. 133-37-9, Name is (2R,3R)-rel-2,3-Dihydroxysuccinic acid, SMILES is O=C(O)[C@H](O)[C@@H](O)C(O)=O, in an article , author is Barmade, Mahesh A., once mentioned of 133-37-9, Category: Benzisoxazole.

Nitrogen containing heterocyclic rings with an oxygen atom is considered as one of the best combination in medicinal chemistry due to their diversified biological activities. Isoxazole, a five membered heterocyclic azole ring is found in naturally occuring ibetonic acid along with some of the marketed drugs such as valdecoxib, flucloxacillin, cloxacillin, dicloxacillin, and danazol. It is also significant for showing antipsychotic activity in risperidone and anticonvulsant activity in zonisamide, the marketed drugs. This review article covers research articles reported till date covering biological activity along with SAR of fused isoxazole derivatives.

The benzisoxazole and pyrimidine moieties are essentially planar and the dihedral angle between these planes is 5.6 (1)-degrees. The piperidine ring is in a slightly distorted chair conformation, while the tetrahydropyridine moiety shows a half-chair conformation. The crystal stucture is stabilized by a hydrogen bond between the H atom on position 4 of the benzisoxazole and the O atom of the pyrimidinone of a translated (x, y-1, z) molecule [C…O = 3.372 (7), H…O = 2.327 angstrom, C-H…O = 161.6-degrees].

A new series of 3-substituted-2,1-benzisoxazoles (anthranils) were prepared by different methods and characterized by spectroscopic methods and mass spectrometry. These 2,1-benzisoxazoles were tested in vitro for their antiplasmodial activity on a chloroquine-resistant strain of Plasmodium falciparum (P.f.) (FcB1), and for antimicrobial activity against representative bacterial and fungal strains, as well as for cytotoxicity on MCF7 human breast cancer cells. Given the log P-calc and selectivity index values (cytotoxicity/antiplasmodial activity ratio), the benzo[c] isoxazol-3- ylmethylene-phenyl-amine (11) (imino-benzisoxazole) was identified as the best hit against P.f. (FcB1), and the benzo[c] isoxazol-3-yl-phenyl-methanone (3) (3-acyl-2,1-benzisoxazole) against P.f. and the Geotrichum candidum fungal strain.

Research speed reading in 2021. Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 627-03-2, Name is 2-Ethoxyacetic acid, SMILES is O=C(O)COCC, in an article , author is Ashwini, Nanjundaswamy, once mentioned of 627-03-2, Formula: https://www.ambeed.com/products/627-03-2.html.

1,2,3-Triazole-based heterocycles have previously been shown to possess significant anticancer activity in various tumor models. In the present study, we attached a 1,2,3-triazole moiety to the third position of a 1,2-benzisoxazole heterocycle via copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) with various alkynes and established for the title compounds significant antiproliferative effect against human acute myeloid leukemia (AML) cells. Among the tested compounds, 3-(4-(4-phenoxyphenyl)-1H-1,2, 3-triazol-1-yl) benzo[d] isoxazole (PTB) was found to be the most potent antiproliferative agent with an IC50 of 2 mu M against MV4-11 cells using MTT assay. Notably, PTB induced cytotoxicity in MOLM13, MOLM14 and MV4-11 cells with selectivity over normal bone marrow cells (C57BL/6). Furthermore, PTB was found to induce cytotoxicity by increasing apoptosis of AML cells (MOLM13, MOLM14 and MV4-11) as well as sub-G1 cell population and apoptotic cells at submicromolar concentrations, as shown by flow cytometry and Annexin-V staining, respectively. On the protein level we suggested histone deacetylases (HDACs) as the potential protein target of those compounds in silico, and the predicted target was next experimentally validated by measuring the variations in the levels of p21, cyclin D and acetylation of histone H3 and tubulin. Molecular docking analysis of the title compounds with the second deacetylase domain of HDAC6 displayed high degree of shape complementarity to the binding site of the enzyme, forming multiple molecular interactions in the hydrophobic region as well as a hydrogen bond to the phenol side-chain of Tyr-782. Thus, 1,2,3-triazole derivatives appear to represent a class of novel, biologically active ligands against histone deacetylases which deserve to be further evaluated in their applications in the cancer field.

The interactions between the template and the functional monomer are a key to the formation of cavities in the imprinted nanogels with high molecular recognition properties. Nanogels with enzyme-like activity for the Kemp elimination have been synthesized using 4-vinylpyridine as the functional monomer and indole as the template. The weak hydrogen bond interaction in the complex is shown to be able to induce very distinctive features in the cavities of the imprinted nanogels. The percentage of initiator used in the polymerisation, ranging from 1% to 3%, although it does not have a substantial effect on the catalytic rate, reduces considerably the imprinting efficiency. The alteration of the template/monomer ratio is also investigated, and the data show that there is considerable loss of imprinting efficiency. In terms of substrate selectivity, a number of experiments have been performed using 5-Cl-benzisoxazole as substrate analogue, as well as 5-nitro-indole as template analogue for the preparation of a different set of nanogels. All the kinetic data demonstrate that the chemical structure of the template is key to the molecular recognition properties of the imprinted nanogels that are closely tailored and able to differentiate among small structural changes.

Along with the metastable 2-(2,4′-dinitrophenylmethylidene)-1,2-dihydropyridine (NH) and the unstable 6-aci-nitro-2-nitro-5-(2-pyridylmethylene)-1,3-cyclohexadiene (OH), the stable form of 2-(2′,4′-dinitrobenzyl)pyridine (DNBP), CH, is photochemically converted into small amounts of 1,2-bis(2′,4-dinitrophenyl)-1,2-bis(2′-pyridyl)ethane, trans-bis[5-nitro-2-(pyridine-2-carbonyl)phenyl]diazene N-oxide, 6-nitro-3-(2′-pyridyl)-2,1-benzisoxazole and 3-nitropyrido[1,2-b]quinolin-6-ium-11-olate. The latent photochromism of DNBP, as shown by x-ray analysis of the structures of the side-products and ESR/IR measurements, is attributed to open-shell reactions that are initiated by hydrogen photoabstraction and subsequent creation of two monoradicals, NH. and OH.. Large amounts of the radicals (ca 50% NH. and 70% OH) confined in the crystalline interior are persistent under ambient conditions. Through quasi-periodic reactions, the remaining radicals partially recover the ground-state isomers CH, NH and OH, or decay to the side-products, which results in crystalline photofatigue. Together with proton tunneling from the excited CH, the radical reactions represent dominant mechanism for the creation of NH and OH in the low-temperature regimes, but are successfully competed by the closed-shell reactions at higher temperatures. The precursor state, whose existence was assumed previously from transient absorption spectroscopy, may be identified as the radical OH.. The present work represents the first study of the photofatigue of a 2-(2,4-dinitrobenzyl)pyridine compound and extends the ‘classical’ mechanism of the photochromic reactions of nitrobenzylpyridines with a set of open-shell radical reaction routes.
