[The electronic structure and radiorprotective activity of a series of substituted iminodihydrofurans]

Compounds that increase the survival rate of lethally exposed hybrid (CBA x C57B1/6)F1 mice have been revealed within the series of iminodihydrofurans. The quantum-chemical estimates, made by the MNDO method, show that substances which are capable of donor-acceptance interaction with DNA nucleotides and have the energy of donor orbitals, comparable with the electron structure of nucleotides, possess radioprotective efficacy.
