Quantitation of the molecular mechanisms of biological synergism in a mixture of DNA-acting aromatic drugs.
It is suggested that the widely reported biological synergism of a mixture of DNA-targeting aromatic drug molecules both in vivo and in vitro can be explained, in part, at the molecular level by competition between two basic mechanisms: the 'interceptor' (hetero-association between Drug1 and Drug2) and 'protector' mechanisms (complexation of Drug1 and Drug2 on DNA-binding sites). In the present work a complete analytical methodology has been developed to quantify these processes, providing an estimate of the relative importance of the interceptor/protector mechanisms using just a set of equilibrium association constants. The general methodology may be applied to other molecules with receptors for aromatic drugs.
