The photobehavior of norharmane (9H-pyrido[3,4-b]-indole) (NHM), one of the vastly used skeleton of drugs in therapeutic applications, has recently been the subject of increasing interest due to the finding of their phototoxic and photocarcinogenic properties. Its absorption and fluorescence behavior from different prototropic species show remarkable sensitivity towards the polarity, viscosity and...
Steady state and time resolved fluorometric and circular dichroism (CD) techniques have been exploited to explore the binding interaction of a ketocyanine dye, namely, 2-[3-(N-methyl-N-phenylamino)-2-propenylidene] indanone (MPAPI) with transport proteins, bovine serum albumin (BSA) and human serum albumin (HSA). The emission spectrum of buffered solution of the dye is found to be perturbed remarkably...
