4-Methyl-N1-(3-phenyl-propyl)-benzene-1,2-diamine (JSH-23) is a novel chemically synthetic compound. The aromatic diamine JSH-23 compound exhibited inhibitory effect with an IC(50) value of 7.1 microM on nuclear factor (NF)-kappaB transcriptional activity in lipopolysaccharide (LPS)-stimulated macrophages RAW 264.7, and interfered LPS-induced nuclear translocation of NF-kappaB without affecting IkappaB degradation. This mechanism of action is very rare for controlling NF-kappaB activation. Furth

A comprehensive treatment of the classical decay rates for a molecule in the vicinity of a spherical surface is presented through the application of the work of van der Pol and Bremmer and that of Fock. This theory takes full advantage of the Hertz vector formalism, which is mathematically simpler than the widely-adapted Lorenz-Mie approach which uses the complicated vector harmonic expansions. Results are obtained for both radiative and nonradiative transfer when the molecule is located outside

The treatment of inflammatory diseases today is largely based on interrupting the synthesis or action of the mediators that drive the host's response to injury. It is on the basis of this concept that most of the anti-inflammatory drugs have been developed. In our continuous search for novel anti-inflammatory agents from traditional medicinal plants, Saposhnikovia divaricata has been a focus of our investigations. Anomalin, a pyranocoumarin constituent of S. divaricata, exhibits potent anti-infl
