Thioarginine (hydrobromide) is a colorimetric substrate for arginase that provides the basis for continuous spectrophotometric measurement of enzyme activity. It exhibits Km and kcat values of 0.

A chromophoric substrate that is used to quantify inorganic phosphate (Pi) in the presence of purine nucleoside phosphorylase, followed by continuous spectrophotometry at an absorbance of 355-360 nm used to measure changes in Pi levels in coupled

A naturally occurring cytokinin that regulates cell division, development, and nutrient processing in plants and serves as a precursor to zeatin synthesis.

A potent and selective competitive inhibitor of nNOS (Ki = 57 nM bovine) exhibits 3,000-fold and 150-fold selectivity for the neuronal isoform versus the inducible (murine Ki = 180 &microM) and endothelial (bovine Ki = 8.5 &microM) isoforms of

A first generation quinoxaline derivative that acts as a noncompetitive antagonist of mGluR1 and mGluR5 (IC50s = 5.2 and 82 nM, respectively).

A quorum sensing signal molecule that controls the expression of many virulence genes as a function of cell population density and can also chelate ferric iron at physiological pH.

A phospholipid containing palimitoyl (16:0) and oleoyl (18:1) acyl substituents at the sn-1 and sn-2 positions, respectively, that been used to generate lipid membrane bilayers with controlled permeability and may be useful for various surfactant
