[The effect of structure of benzimidazoles on the character of forming intramolecular cross-links in DNA and chromatin].

An investigation of a number of benzimidazole class preparations, being distinguished by a position of aminomethyl substitutes, has been carried out. It has been shown, that the non-substituted preparation BIO-10 does not form UV-cross-links in DNA and chromatine; BIO-40, having one substitute in the position 2, causes the formation of inter-molecular cross-links DNA-DNA. The preparation BIO-50, having 2 aminomethyl groups in the imidazole nucleus positions 2 and 6, forms cross-links DNA-DNA and DNA-protein in chromatine.
