An in situ prepared Zn(2+) complex of triazole linked imino-thiophenyl conjugate of calix[4]arene, [ZnL], was demonstrated to be highly fluorescent in HEPES buffer solution. [ZnL] has been used as a chemo-sensing ensemble for the recognition of phosphates in general and

NkBgl, a β-glucosidase from Neotermes koshunensis, is a β-retaining glycosyl hydrolase family 1 enzyme that cleaves β-glucosidic linkages in disaccharide or glucose-substituted molecules. β-Glucosidases have been widely used in several applications. For example, mutagenesis of the attacking nucleophile in β-glucosidase

A highly fluorescent Zn(2+) complex of the triazole linked salicyl-imino-thiophenyl conjugate of calix[4]arene, [ZnL] has been demonstrated to be a chemo-sensing ensemble for the recognition of His and Cys among the naturally occurring amino acids in HEPES buffer milieu. The

A ratiometric fluorescence sensor based on pyrene was designed for selective detection of heparin in HEPES (N-(2-hydroxyethyl)piperazine-N'-ethanesulfonic acid) buffer and serum sample. Pyrene and long-chain alkanes were linked through bisquaternary functionality in the sensor which could interact with heparin via

The mechanisms of action of endogenous modulatory ligands of connexin channels are largely unknown. Previous work showed that protonated aminosulfonates (AS), notably taurine, directly and reversibly inhibit homomeric and heteromeric channels that contain Cx26, a widely distributed connexin, but not
