Abstract

Objectives The purpose of this work was to study the chemical stability of the new antitumoral β-lapachone (βLAP) to determine the degradation pathway/s of the molecule and the degradation kinetics in addition to identifying several degradation products. Method Samples of βLAP in solution were stored under conditions of darkness and illumination at 40 C at which the pseudo-first order rate constants for the βLAP degradation were ...
