The present paper describes a mild and efficient method to synthesize 3-aminosubstituted isothiazole sulfoxides taking advantage of arylsulfonyloxaziridines. The reactivity of the resulting isothiazole sulfoxides toward sulfur nucleophiles has been studied and resulted in the formation of 5-sulfanylsubstituted isothiazoles in a fully diastereoselective way. From 3-benzylamino-5-chloro isothiazole S-oxide an addition-elimination reaction took place affording smoothly the corresponding unsaturated 5-sulfanyl derivatives.

Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield. If you are hungry for even more, make sure to check my other article about 383-29-9, Recommanded Product: 383-29-9.

Electrospinning of pyrazole-isothiazole derivatives: nanofibers from small molecules

We investigate the electrospinning of small molecules, specifically designed peptide derivatives of the pyrazole-isothiazole scaffold. Such non-natural peptides enhance the spectrum of fundamental materials used for electrospinning. Unlike standard electrospun materials, our peptides are not polymeric, but able to aggregate in solution and especially during processing. They contain donor/acceptor groups that can form hydrogen bonds, and groups that are able to generate pi-stacking interactions, which are known as important requirements for assembly processes. The pyrazole-isothiazole derivatives were synthesized by means of a 1,3-dipolar cycloaddition reaction, which is completely regioselective, affording only one isomer. We demonstrate that our compounds can be electrospun from fluoroalcohol solution into solid, quasi-endless micro- and nanofibers. The electrospinnability varies substantially, depending on the amino acids linked to the scaffold. Some compounds provide only short fibers, while Fmoc-glycyl-(N-benzyl)-pyrazole-isothiazole-tert-butyl carboxylate-1,1-dioxide forms continuous, homogenous, and bead-free fibers (droplet-like beads are a common problem in electrospinning). We analyzed the compounds and the fibers with various spectroscopic techniques (MS, IR and Raman). Electrospinning does not change chemical composition and configuration, suggesting the monomeric form of the compounds even in the fibers. Interestingly, we found that the stereochemistry of the scaffold can affect the ability of the peptide to be electrospun.

Synthesis of N,N ‘-linked bisazaheterocycles with sulfonamide structure via oxidation of S,N-heteroaromatic cations

N-Phthalimidyl- and N-quinazolinyl-substituted 3-hydroperoxy-, 3-hydroxy- and 3-oxoisothiazole 1,1-dioxides have been synthesized by the sequence of oxidation reactions from N,N’-linked isothiazolium perchlorates with hydrogen peroxide, MMPP, and pyridinium dichromate. Isothiazolium salts without acceptor substituents did not give N-substituted sultams. Novel N,N’-bisazaheterocycles were investigated as inhibitors of acetylcholinesterase (AChE) and human leukocyte elastase (HLE). Two 2,3-dihydro-3-hydroperoxy-2-(phthalimid-1-yl)isothiazole 1,1-dioxides were found to inhibit AChE.

Heterocycles as bioisosteres for the omega-carboxylate moiety of glutamate in AMPA receptor agonists: A review and theoretical study.

(S)-2-Amino-3-(3-hydroxy-5-methylisoxazol-4yl)propionic acid (AMPA) is the prototypical selective agonist for the AMPA subtype of excitatory amino acid (glutamate) receptors. Several 3-hydroxyisoxazole analogues are known to have activity at this receptor, as do a number of other alanine-substituted heterocyclic phenols, the acidic heterocycles being bioisosteres for the omega-carboxylate moiety of glutamate. The increasingly diverse range of known AMPA agonists is reviewed, including a number of novel pyridazine-based analogues. By removal of a common glycine unit, the parent heterocycles 3hydroxy-4,5-dimethyl-isoxazole, 3-hydroxy-4,5-dimethyl-isothiazole, 4-methyl-5-isoxazolone, 3-hydroxy-4-methyl-1,2,5-thiadiazole, 2-methyl-3,5-dioxo-1,2,4-oxadiazolidine, 1-methyl uracil, 6-aza-1-methyl uracil, and 3-hydroxy-4-methyl-pyridazine 1-oxide are modelled as representative of the known omega-carboxylate bioisosteres. In addition, heterocyclic fragments of inactive hydantoin and 3,5-dioxotriazole quisqualate analogues, and pyridazinone fragments with derivatives of varying potency are considered. These structures and their conjugate bases are subjected to high level ab initio calculations up to G2(MP2) theory, and semi-empirical aqueous phase calculations using the AM1-SM2 model. Their tautomerism and aqueous pK(a) behaviour are studied in detail, and compared with experimental data. Molecular geometries and electrostatic potential-derived charge distributions are presented. Electrostatic properties at the Van der Waals surface are compared. Calculated properties are discussed with respect to structural requirements for AMPA receptor activity. Tridentate models of AMPA receptor binding are presented.

THE PREPARATION OF 1,2,3,5-DITHIADIAZOLIUM CHLORIDES FROM THE REACTION OF NITRILE SULFIDES WITH THIAZYL CHLORIDE

Adamantyl-1,3,4-oxathiazol-2-one has been prepared for the first time and from it l-adamantyl nitrile sulphide has been generated. Characterisation data are presented, including the X-Ray crystal structure of the oxathiazolone. (Crystal data for C12H15NO2S: monoclinic, space group P2(1)/c, a = 11.334(2) Angstrom, b = 7.344(1) Angstrom, c = 14.373(2) Angstrom, beta = 107.74(1)degrees, V = 1139.5(3) Angstrom(3), Z = 4, R = 0.042). The planar heterocyclic ring is similar to structures observed in the gas phase for other oxathiazolone derivatives. The nitrile sulphide was reacted with dimethyl-acetylene dicarboxylate in situ to give an isothiazole derivative. The X-Ray crystal structure of 3-adamantyl-4,5-bis(methoxycarbonyl)-isothiazole has been obtained. (Crystal data for C17H21NO4S: monoclinic, space group P2(1)/n, a = 7.305(4) Angstrom, b = 7.339(4) Angstrom, c = 31.552(4) Angstrom, beta = 92.75(3)degrees, V = 1690(1) Angstrom(3), Z = 4, R = 0.079). A general cycloaddition reaction was discovered between the nitrile sulphides and thiazyl chloride to give 1,2,3,5-dithiadiazolium chlorides. The structure of the new 4-adamantyl-1,2,3,5-dithiadiazolium chloride was confirmed by reduction to the 4-adamantyl-1,2,3,5-dithiadiazolyl for which the X-Ray crystal structure has been determined. (Crystal data for C11H15N2S2: monoclinic, space group C2, a = 10.284(4) Angstrom, b = 8.651(2) Angstrom, c = 13.669(2) Angstrom, beta = 112.83(1)degrees, V = 1120.9(4) Angstrom(3), Z = 4, R = 0.042). The radical adopts a twisted dimer structure in the solid state which is similar to the structures observed for other alkyl derivatives.

Antipoliovirus activity and mechanism of action of 3-methylthio-5-phenyl-4-isothiazolecarbonitrile

Our previous studies described the synthesis and the antiviral activity of 3,4,5-trisubstituted isothiazole derivatives that were found to be particularly effective against enteroviruses. Compound 3-methylthio-5-phenyl-4-isothiazolecarbonitrile (IS-2) exhibited an interesting anti-poliovirus activity with a high selectivity index. In the present study we investigated the mechanism of action of this compound. Studies on the time of IS-2 addition to poliovirus type 1 infected cells suggested that the compound may inhibit some early process of viral replication. In order to determine its mechanism of action, we evaluated the rate of attachment and internalization of purified [(3)H]uridine-labeled poliovirus to HEp-2 cells in the presence or absence of IS-2. No effect on poliovirus adsorption and internalization to host cells was detected. We also investigated the influence of the compound on virus uncoating using labeled poliovirus and measuring the radioactivity of oligoribonucleotides formed from viral RNA susceptible to ribonuclease. These experiments demonstrated that poliovirus uncoating is influenced by IS-2 action. (C) 2010 Elsevier B.V. All rights reserved.

REACTIONS OF CHELATED BETA-FUNCTIONALIZED AMINO-ACIDS WITH THIONYL CHLORIDE

A variety of bis(ethane-1,2-diamine)cobalt(III) complexes containing chelated beta-functionalized amino acids have been treated with SOCl2 in dimethylformamide. These compounds undergo beta-elimination reactions to give chelated enamines followed by either rearrangement to the related imine complexes or further reactions with SOCl2 to give chelated isothiazole-3-carboxylato complexes. Mechanisms are proposed for the reactions.
