In a document, author is Mihara, Gen, introduce the new discover, Electric Literature of 122-75-8.

A Rh(III)-catalyzed annulative coupling of 3,5-diarylisothiazoles and alkynes is reported. The N-S bond in the isothiazole ring acts as an internal oxidant to regenerate the Rh(III) species in combination with an external Cu(II) oxidant, and the corresponding 1:2 coupling products are obtained. The remarkable difference in the reaction outcome between isothiazoles and the relevant isoxazoles has been investigated by DFT calculations, revealing that the relative stability of the enolate intermediates dictates the product selectivity.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about 122-75-8. Electric Literature of 122-75-8.

In a article, author is Hamama, W. S., introduce new discover of the category.

A new class of N-basic side chains was obtained from 2,3-dihydro-2H-3-oxobenzo[d] isothiazole and aliphatic or aromatic aldehydes. Secondary amines (morpholine, N-methylpiperazine and ethyl isonipecotate) afforded tertiary N-basic side chains (4-6), while dibasic secondary amines (such as piperazine) gave bis-tertiary N-basic side chains (2). On the other hand, the use of mono-or dibasic primary amines namely; aniline, anisidine, phenyl hydrazine, o-hydroxy benzoic acid hydrazide, hydrazine hydrate, and ethylenediamine (instead of secondary amines) afforded secondary N-basic side chain as mono component or as bis component 7a-c, 9a-c, 11 and 12a-c. In addition, secondary Mannich base was synthesized via Michael addition to the corresponding aldimine. The new compounds were investigated for antioxidant and antimicrobial activities. Compounds 2, 7c and 12a exhibited significant antimicrobial activity, whereas compounds 7a, 7b, 9b, 9c and 11 exhibited high antioxidant activity as compared to ascorbic acid, These compounds showed the best protective effect against DNA damage induced by bleomycin.

The alternative way of synthesis of valuable 5-amino-3-methylisothiazole and 3-methyl-4-nitroisothiazole has been presented and described. It appeared that new, undescribed 3,3′-dimethyl-4,4′-dinitro-5,5′-bisisothiazole has been produced as a side-product during synthesis. Both experimental and calculated spectral and electronic properties of 3-methyl-4-nitroisothiazole have been extensively researched and discussed. The complete vibrational assignments were made on the basis of potential energy distributions PED. The fully anharmonic infrared and Raman spectra with calculated anharmonic intensities for fundamental bands, overtones as well as combination bands are presented. Vibrational spectra predicted by anharmonic approximation agree very well with experimental data. The stability of molecules of 3-methyl-4-nitroisothiazole arising from hyper conjugative interaction has been estimated using natural bond orbital (NBO 6.0) analysis. The combined frontier molecular orbital and NBO analysis of canonical molecular orbitals was used to predict the most probable sites of 3-methyl-4-nitroisothiazole molecule where single electron can be accepted to and detached from. Measured reduction potential of 3-methyl-4-nitroisothiazole and calculated electron affinity point out that this compound is susceptible to reduction at the similar level of 1-methyl-3-nitropyrazole and this susceptibility is much more than respective 1-methyl-4-nitropyrazole. UV-Vis spectra analysis reveals a nature of valence electron excitation and electron transition of 3-methyl-4-nitroisothiazole. Besides, unambiguous assignment of NMR signal shifts of carbon atoms of isothiazole ring of 3-methyl-4-nitroisothiazole, 5-amino-3-methylisothiazole and intermediate and side products of synthesis was conducted thanks to full detailed analysis of H-1, C-13 NMR spectra and their two dimensional (2D) variants. Additionally, molar enthalpy of vaporization (Delta H-vap) of 3-methyl-4-nitroisothiazole has been estimated (Delta H-vap = 52.2 kJ/mol). (C) 2019 Elsevier B.V. All rights reserved.

Acetic acid derivatives of naphtho[1,2-dlisothiazole (NiT) were synthesized and tested as novel aldose reductase (ALR2) inhibitors. The parent compound 11 exhibited a fair inhibitory activity (IC50 = 10 mu M), which was enhanced by 2 orders of magnitude by introducing a second carboxylic group at position 4 (13 and 14: IC50 = 0.55 and 0.14 mu M, respectively). Substitution of the acetic acid function with an apolar group gave inactive (29) or poorly active (25, 26, 30) compounds, thus demonstrating that the 2-acetic group is involved in the enzyme pharmacophoric recognition while the 4-carboxylic moiety has only an accessory role. The potent compounds 11, 13, 14, 26 all proved to be selective for ALR2, since none of them inhibited aldehyde reductase, sorbitol dehydrogenase, or glutathione reductase. The isopropyl. ester 31, a prodrug of 14, was found to be effective in preventing cataract development in severely galactosemic rats, when administered as an eyedrop solution. The theoretical binding mode of 13 and 14, obtained by docking simulations into the ALR2 crystal structure, was fully consistent with the structure-activity relationships in the NiT series.

Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments. 1235-74-1, Name is (1R,4aS,10aR)-methyl 7-isopropyl-1,4a-dimethyl-1,2,3,4,4a,9,10,10a-octahydrophenanthrene-1-carboxylate, SMILES is O=C([C@]1(C)CCC[C@]2(C)C3=C(CC[C@@]12[H])C=C(C(C)C)C=C3)OC, in an article , author is Popova, Maria V., once mentioned of 1235-74-1, Electric Literature of 1235-74-1.

We have introduced a strategy for the construction of spirocycloalkane 1 lambda(6)-isothiazolidine-1,1,4-triones through the mesylation of 1-aminocyclopentane-, 1-aminocyclohexane-, and 1-aminocycloheptanecarboxylic acid esters with methanesulfonylchloride followed by alkylation with methyl iodide and consequent cyclization in the presence of potassium tert-butoxide in N,N-dimethylformamide. The spirocycloalkane 4-amino-2,3-dihydro-1H-1 lambda(6)-isothiazole-1,1-diones were prepared via mesylation of N-methylated 1-aminocyclopentyl-, 1-aminocyclohexyl-, and 1-aminocycloheptyl carbonitriles followed by treatment of obtained N-(1-cyanocycloalkyl)-N-methylmethanesulfonamides with potassium tert-butoxide in N,N-dimethylformamide. The spiro 4-amino-2,3-dihydro-1H-1 lambda(6)-isothiazole-1,1-diones were converted into the target spiro 1 lambda(6)-isothiazolidine-1,1,4-triones by acid-catalyzed hydrolysis. The structure of a target spiro compound and its isolated key intermediate was confirmed by X-ray diffraction study. The interaction of spiro 1 lambda(6)-isothiazolidine-1,1,4-triones with N,N-dimethylformamide dimethyl acetal leads to the formation of spiro 5-[(Z)-(dimethylamino)methylidene]-1 lambda(6)-isothiazolidine-1,1,4-triones.

On the basis of computer prediction of biological activity by PASS and toxicity by DEREK, the most promising 32-alkylaminoacyl derivatives of 3-aminobenzo[d]isothiazole were selected for possible local anaesthetic action. This action was evaluated using an in vitro preparation of the isolated sciatic nerve of the rat and compared with lidocaine which was used as a reference compound. QSAR studies showed that the polarizability, polarity and molecular shape of molecules have a positive influence on their local anaesthetic activity, while contributions of aromatic CH and singly bonded nitrogen are negative. Since the estimated PASS probabilities to find local anaesthetic activity in the most active compounds are less than 50%, these compounds may be considered to be possible NCEs.

Natural products have contributed to the elucidation of biological mechanisms as well as drug discovery research. Even now, the expectation for natural products is undiminished. We screened prostaglandin release inhibitors that had no effect on in vitro cyclooxygenase activity derived from natural product sources and discovered pronqodine A. Using spectral analysis and total synthesis, the structure of pronqodine A was shown to be a benzo[d]isothiazole-4,7-dione analogue. Evaluation of the biological activity of pronqodine A revealed that the NAD(P)H dehydrogenase quinone 1 (NQO1) converted pronqodine A into a two-electron reductive form. The reductive form underwent autoxidation and reversed to its native form immediately with the generation of reactive oxygen species. Further investigations proved that pronqodine A inhibited cyclooxygenase enzyme activity only in the presence of NQO1. Pronqodine A acts as a potential bioreductive compound, inhibiting prostaglandin release in selectively activated NQO1-expressing cells.
