Abstract:
Process for inhibiting deoxyribonucleotide triphosphate biosynthesis by cells, comprising application onto said cells of at least one of the azo derivatives of the formula ##STR3##in which R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are identical or different and each represent a hydrogen or halogen atom or an optionally substituted aliphatic or aromatic hydrocarbon residue, R.sup.1 and R.sup.2 possibly being connected together to form a heterocyclic nucleus with the nitrogen atom adjacent thereto, and R.sup.3 and R.sup.4 possibly being connected together to form a heterocyclic nucleus with the nitrogen atom adjacent thereto, X.sup.1 and X.sup.2 are identical or different and each represent an oxygen atom or a group NR.sup.5, in which R.sup.5 is a hydrogen or halogen atom, an optionally substituted aliphatic or aromatic hydrocarbon residue, or a nitro group, and in which, when two groups NR.sup.5 are simultaneously present, each R.sup.5 may be identical to or different from the other, as well as the isomers thereof.
