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.

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.

Discovering protein-ligand chalcogen bonding in the protein data bank using endocyclic sulfur-containing heterocycles as ligand search subsets

The chalcogen bond, the noncovalent, electrostatic attraction between covalently bonded atoms in group 16 and Lewis bases, is present in protein-ligand interactions based on X-ray structures deposited in the Protein Data Bank (PDB). Discovering protein-ligand chalcogen bonding in the PDB employed a strategy that focused on searching the database for protein complexes of five-membered, heterocyclic ligands containing endocyclic sulfur with endo electron-withdrawing groups (isothiazoles; thiazoles; 1,2,3-, 1,2.4-, 1,2,5-, 1,3,4-thiadiazoles) and thiophenes with exo electron-withdrawing groups, e.g., 2-chloro, 2-bromo, 2-amino, 2-alkylthio. Out of 930 ligands investigated, 33 or 3.5% have protein-ligand S-O interactions of which 31 are chalcogen bonds and two appear to be S-HO hydrogen bonds. The bond angles for some of the chalcogen bonds found in the PDB are less than 90 degrees, and an electrostatic model is proposed to explain this phenomenon.

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.

4-Amino-2,3-dihydro-lambda 1(6)-isothiazole-1,1-dioxides and their chemical properties evaluation

The reactivity of the 4-amino-2,3-dihydro-1H-lambda 1(6)-isothiazole-1,1-dioxide (beta-amino-gamma-sultam) framework has not been studied sufficiently. Here we describe the chemical properties of this heterocyclic system toward electrophiles on spiranic and non-spiranic substrates. A variety of C-electrophiles (acetic anhydride, benzoyl chloride, DMFDMA, 4,4-dimethoxybutan-2-one) and heteroatom electrophiles (bromine, nitrosyl acetate) have been explored. Both the C-5 and 4-amino positions of the beta-amino-gamma-sultam system are able to undergo electrophilic reactions. Heteroatom electrophiles attack the C-5 position, whereas carbo-electrophiles affect the amino group. beta-Amino-gamma-sultams also were used as starting compounds for the synthesis of 6- or 7-substituted 1 lambda(6)-isothiazolo[4,5-b]pyridine-1,1-dioxides through condensation reaction and palladium-catalyzed oxidative coupling.
