Optimisation at B3LYP/6-311G(d,p) was used in a DFT study of the characteristics 2-methylthio(methylsulfonyl)-triazoloquinazolines (1, 2). The design-critical role intramolecular hydrogen bonding stabilising both structures is emphasised. stability crystal consequence interactions between its molecules. According to global index, 2-methylthio-triazoloquinazoline (1) more electrophilic and react...
The production of fungal metabolites can be remarkably influenced by various cultivation parameters. To explore the biosynthetic potentials of the marine fungus, Neosartorya pseudofischeri, which was isolated from the inner tissue of starfish Acanthaster planci, glycerol-peptone-yeast extract (GlyPY) and glucose-peptone-yeast extract (GluPY) media were used to culture this fungus. When cultured...
Crystal structure of (E)-2-(2-chloro-5-nitrostyryl)-1-(methylthio)methylbenzimidazole, C17H14ClN3O2S
A new precursor 2-(1-cyano-2,2-bis(methylthio)vinyl)benzonitrile has been synthesized by the reaction of 2-cyanomethylbenzonitrile, carbon disulfide and methyl iodide under basic conditions. The reaction of 2-(1-cyano-2,2-bis(methylthio)vinyl)benzonitrile with various functionalized aryl/heteroaryl methyl ketones or acetone under basic conditions afforded 4-amino-3-aroyl/heteroaroyl/acetyl-2-me...
N-Substituted amides of endo-3-(3-methylthio-1,2,4-triazol-5-yl)bicyclo[2.2.1]hept-5-ene-2-carboxylic acid and 1-(5-methylthio-1,2,4-triazol-3-yl)cyclohexane-2-carboxylic acid were prepared by the condensation reaction of endo-S-methyl-N1-(bicyclo[2.2.1]hept-5-ene-2,3-dicarbonyl)isothiosemicarbazide and S-methyl-N1-(cyclohexane-2,3-dicarbonyl)isothiosemicarbazide with primary amines. The synthe...
Although resistance to the P2Y12 antagonist clopidogrel is linked to altered drug metabolism, some studies suggest that these pharmacokinetic abnormalities only partially account for drug resistance. To circumvent pharmacokinetic complications and target P2Y12 receptor function we applied the direct P2Y12 antagonist 2-methylthio-AMP (2-methylthioadenosine 5'-monophosphate triethylammonium salt)...
Total syntheses of 4-methylthio-3-butenylisothiocyanate (MTBI, 1) and raphanusanin (2), which are growth inhibitors involved in the phototropism radish (Raphanus sativus) hypocotyls, were achieved from commercially available thiolane four five steps, respectively. MTBI (1) was prepared via ring opening with sodium azide, double bond introduction by oxidation, isothiocyanation. Cyclization to (2...
