New classes of carborane-appended 5-thio-D-glucopyranose derivatives.
A series of carborane-appended 5-thio-D-glucopyranose (5-TDGP) derivatives containing one to two 5-TDGP moieties were synthesized via click cycloaddition reaction as well as following the traditional methods. Among the carboranyl-5-TDGP derivatives, the decapitated nido-carboranyl derivative 18 was found to be highly water-soluble and therefore its preliminary biodistribution study was conducte...
متن کاملSynthesis of new 2-thio-[1,2,4]triazolo[1,5-c]quinazoline derivatives and its antimicrobial activity.
A series of novel ([1,2,4]triazolo[1,5-c]quinazolin-2-ylthio)carboxylic acids 2a-d and esters 3a-l were synthesized and evaluated for antimicrobial activity. Alkylation of potassium 2-thio-[1,2,4]triazolo[1,5-c]quinazoline 1 with halogenocarboxylic acids and its esters proceeded S-regioselectively. During acid catalyzed esterification of 2a-c, degradation of the pyrimidine ring was observed. Th...
متن کاملCrystal structures of four chiral imine-substituted thio-phene derivatives.
A series of thio-phenes substituted in positions 2 and 5 by imine groups have been synthesized using a solvent-free approach, and their crystal structures determined. The substituents are chiral groups, and the expected absolute configuration for each mol-ecule was confirmed by refinement of the Flack parameter. The compounds are 2,5-bis-[(S)-(+)-(1,2,3,4-tetra-hydro-naphthalen-1-yl)imino]-thio...
متن کاملA facile and general route to 3-((trifluoromethyl)thio)benzofurans and 3-((trifluoromethyl)thio)benzothiophenes.
A facile and general route to 3-((trifluoromethyl)thio)benzofurans and 3-((trifluoromethyl)thio)benzothiophenes is reported. The reactions of trifluoromethanesulfanylamide with 1-methoxy-2-alkynylbenzenes or methyl(2-alkynylphenyl)sulfanes promoted by BiCl3 proceed smoothly with broad functional group tolerance.
متن کاملEvaluation of the Mycobactericidal Effect of Thio-functionalized Carbohydrate Derivatives.
Sugars with heteroatoms other than oxygen have attained considerable importance in glycobiology and in drug design since they are often more stable in blood plasma due to their resistance to enzymes, such as glycosidases, phosphorylases and glycosyltransferases. The replacement of oxygen atoms in sugars with sulfur forms thio-sugars, which are potentially useful for the treatment of diabetes an...
