Abstract
Camptothecins, fluorescent anticancer agents, exhibit at neutral and physiological pH changes over time in absorption and fluorescence spectra. Analysis of these changes is a subject of this paper. Factor analysis of fluorescence spectra enabled to determine the kinetics of hydrolysis of camptothecin, i.e. the rate of converting of biologically active lactone form into inactive carboxylate. Obtained results are compared with HPLC data.
