The solvatochromic fluorophore 4-N,N-dimethylamino-1,8-naphthalimide (4-DMN) possesses extremely sensitive emission properties due largely to the low intrinsic fluorescence it exhibits in polar protic solvents such as water. This makes it well suited as a probe for the detection of a wide

Class I hybrid poly(N-isopropylacrylamide)/silica hydrogels, PNIPAM/SiO2, were prepared by a new one shot synthesis. In this approach, the free-radical polymerization of vinyl groups of N-isopropylacrylamide (NIPAM) and the hydrolysis-condensation of alkoxy groups of tetramethoxysilane (TMOS) are performed concomitantly using sodium

The neurotoxic aminonitrile dimethylaminopropionitrile (DMAPN) inhibits the crystalline glycolytic enzymes glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and fructose-6-phosphate kinase (phosphofructokinase, PFK). Preincubation of GAPDH with the aminonitrile enhances the inhibition, indicating that the inhibition is irreversible. The overall bimolecular rate constant ki was

N,N'-Dimethylaminopropionitrile (DMAPN), a major component of the NIAX catalyst ESN, is known to cause urinary bladder dysfunction in exposed workers. In order to investigate the mechanism of DMAPN toxicity, we carried out time-course (0-72 h) and dose-response (175-700 mg/kg) studies
