Application of pulse radiolysis to the study of drug interactions with biological macromolecules.

Pulse radiolysis has been used to study the interactions of a variety of small molecules with DNA. The diffusion-controlled rate constants for the reactions of e(aq) with dyes, cations and other small molecules including radioprotectors and radiosensitizers, were found to decrease remarkably upon association with DNA. These kinetic data can be used to… CONTINUE READING
