A series of nitroaromatic compounds was synthesized and evaluated as potential antileishmanial and trypanocidal agents. Five compounds exerted significant anti-leishmanial activity in vitro against promastigotes forms of Leishmania (L.) amazonensis, with IC50 in the range of 23–59 μmol L−1, but none were active against amastigotes intracellular forms of Trypanosoma cruzi. In vitro cytotoxicity on the
A general assay for monitoring catalysis by fluorescence in real time has been developed by use of an antibody sensor. The sensor consists of a product-specific antibody tightly bound to a product analogue covalently labeled with the fluorescent tag acridone. Acridone fluorescence is quenched in the bound state. The reaction is monitored by following the fluorescence increase caused by displacement of the acridone-labeled product from the antibody combining site by the released product. Fluorescence detection of enzymatic hydrolysis of a beta-galactoside and butyrate by beta-galactosidase and esterase, respectively, are demonstrated. The assay operates by modulation of fluorescence intensity at 445 nm, a signal compatible with currently available instruments measuring in 96-well or 384-well plastic microtiter plates. The method is potentially general and only limited by binding selectivities of the product versus the substrate that can be encountered in antibodies.
