the interaction between propranolol (prop) and human serum albumin (hsa) was studied in the presence of dimethyl methylphosphonate (dmmp). dmmp is usually considered as a simulant for chemical warfare agents (cwas). for this purpose fluorescence quenching, resonance light scattering (rls), synchronous, three-dimensional fluorescence spectroscopy and molecular dynamics (md) simulation were emplo...

in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...

The interaction of tetrandrine with human serum albumin (HSA) was studied by measuring fluorescence quenching spectra, synchronous fluorescence spectra and ultra-violet spectra. The fluorescence quenching spectra of HSA in the presence of tetrandrine showed that tetrandrine quenched the fluorescence of HSA. The quenching constants of tetrandrine on HSA were determined using the Stern-Volmer equ...
