All samples studied exhibited semiconductor properties. Conductivity at room temperature varied between 10-4 and 10-9 (Ω·cm)-1. We proved the dependence of the conductivity on the length of the R10 and R2 substituents. The relationship between the parameters defining the electric conductivity and the pharmacological activity was also shown. ACKNOWLEDGMENTS The authors wish to thank Drs. F. Rueda and J. M.
