Synthesis, antiproliferative and antiviral activity of imidazo[4,5-d]isothiazole nucleosides as 5:5 fused analogs of nebularine and 6-methylpurine ribonucleoside

A series of imidazo[4,5-d]isothiazole nucleosides related to the antibiotic nebularine and the highly cytotoxic 6-methyl-9-beta-D-ribofuranosylpurine have been synthesized from the corresponding heterocycles. The sodium salt glycosylation of the imidazo[4,5-d]isothiazoles proceeded smoothly, giving mixtures of N-4 and N-6 regioisomers in generally good yields. The protected derivatives were deblocked using standard conditions to afford the desired imidazo[4,5-d]isothiazole nucleosides, usually as crystalline solids. None of the new nucleosides or heterocycles displayed selective activity against human cytomegalovirus (HCMV) or herpes simplex virus type 1 (HSV-1). The N-6 glycosylated imidazo[4,5-d]isothiazoles were completely inactive up to the highest concentration tested. The N-6 glycosylated imidazo[4,5-d]isothiazoles also were inactive in antiproliferative and cytotoxicity assays, except for 3-methyl-6-beta-D-ribofuranosylimidazo[4,5-d]isothiazole (15a) and 5-(benzylthio)-6-(2-deoxy-beta-D-ribofuranosyl)imidazo[4,5-d]isothiazole (5e), which showed moderate inhibition of L1210 cell growth. However, the heterocycles and several of the N-4 glycosylated derivatives were toxic to HFF, KB and L1210 cells; compounds with 5-benzylthio substituents were the most cytotoxic agents in this series.

Identification of novel, selective and potent Chk2 inhibitors

A series of isothiazole carboxamidine compounds were synthesized and discovered as novel and selective inhibitors for Chk2. They are not active against the related Chk1 kinase. The structure-activity relationship studies were performed on the scaffold, and enzymatic kinetic analysis showed they are simple ATP competitive inhibitors with K-i values as low as 11 nM for Chk2. Computer modeling studies were employed to comprehend the mechanism of action and SAR of these compounds. (c) 2006 Elsevier Ltd. All rights reserved.

ISOTHIAZOLES .3. CYCLOADDITIONS OF DIAZOALKANES TO 3-DIALKYLAMINOISOTHIAZOLE 1,1-DIOXIDES – COMPETITIVE RING-CLEAVAGE IN 3A,4-DIHYDRO-6AH-PYRAZOLO[3,4-D]ISOTHIAZOLE 1.1-DIOXIDES – FORMATION OF 2-THIA-3-AZABICYCLO[3.1.0]HEX-3-ENE 2,2-DIOXIDES AND/OR PYRAZOLES

3-Dialkylaminoisothiazole 1,1-dioxides 1 readily undergo cycloadditions with diazoalkanes 2. The reaction is characterized by high site- and regio-selectivity. Cycloadducts 3 and 4 were found to undergo straightforward thermolysis reactions at elevated temperature through two different paths characterized respectively by loss of nitrogen or sulfur dioxide and diethylcyanamide. The different transformations affording pyrazoles 6 and derivatives of the new heterocycle 2-thia-3-azabicyclo[3.1.0]hex-3-ene 2,2-dioxide 5 are discussed.

In vitro and in vivo anticryptococcal activities of a new pyrazolo-isothiazole derivative

We investigated the activity of a pyrazolo-isothiazole derivative (G8) against Cryptococcus neoformans. A first screening test showed that G8 at 10 mg/L inhibited the growth of 14 of 15 clinical isolates tested. Killing experiments showed that fungicidal activity was achieved after 8 h of treatment with G8 at concentrations greater than or equal to10 mg/L. In a murine model of systemic cryptococcosis, G8 was effective at prolonging survival compared with the controls. Our data indicate that this new derivative has a potential therapeutic role in infections caused by C. neoformans.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 80-07-9. Application In Synthesis of 4,4′-Sulfonylbis(chlorobenzene).

4,5-Disubstituted N-phenyl-isothiazolium salts 1 with active 5-methyl group react under the influence of anilines to form 3,4-disubstituted isothiazolium salts 3. The influence of donor and acceptor substituents in the 2-phenyl group of 1a-h and in the anilines 2 on the ring transformation were studied. The structure of the new salts was confirmed by X-ray analysis. The 3-hydroperoxy-2,3-dihydro-isothiazole 1,1-dioxides (12a,d)and the isothiazole-3(2H) -one 1,1-dioxides (14a,d) are obtained by oxidation of salts 3 with H2O2.

Synthesis and monolayer behaviors of 4-methyl-5-hydroxy-ethyl isothiazole stearic ester

4-methyl-5-hydroxy-ethyl isothiazole stearic ester(HISE) was synthesized and characterized by FTIR spectroscopy, H-1 NMR and MS. The monolayer-forming ability of HISE was studied in subphases with different pH values using isotherms of surface pressure-area per molecule (pi-A). It was observed that the collapse pressure and the film-forming ability of the monolayers of HISE increased gradually as pH values ascended. Research of differentiated pi-A curves (dpi(/dA – A) indicated that there were one or two phase change points during the compressing process, and the incompressibility and the stability of HISE monolayers on alkalescent subphases were better than on acid subphases.

INVITRO ANTIVIRAL ACTIVITY OF 4 ISOTHIAZOLE DERIVATIVES AGAINST POLIOVIRUS TYPE-1

The in vitro effects of four isothiazoles [5,5′-diphenyl-3,3′-diisothiazole disulfide, 5-phenyl-3-mercapto-isothiazole, 5,5′-(4-chlorophenyl)-3,3′-diisothiazole disulfide, and 5-(4-chlorophenyl)-3-mercapto-isothiazole] on poliovirus type 1 were studied. The derivatives tested demonstrated remarkable viral inhibition, with a higher selectivity index than the previously studied iminodithiole precursors. Under one-step growth conditions, all the isothiazole derivatives caused the greatest activity if added during or after (within 1 h) pollovirus adsorption. These data suggest interference with early events of viral replication. [5-H-3]Uridine incorporation into RNA showed that the compounds tested reduced pollovirus RNA synthesis, which was completely shut off after 2 h of incubation and reduced by 50-60% after 4 h. Also, pretreatment of the cell cultures with the compounds for 24 h caused a substantial inhibition of viral replication. The data suggest that the four isothiazole derivatives may have a multi-step antiviral mode of action different from their iminodithiole precursors.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 114772-54-2. Name: 4′-(Bromomethyl)-[1,1′-biphenyl]-2-carbonitrile.
