The invention refers to new efficacious products for the prevention and therapy of cataract, derivatives of 7-amino-2-dialkylaminoalkyl-1H-pyrrol [3.4-c] pyridine-1.3(2H)-dione of general formula, I
where R represents an atom of hydrogen, a methyl or ethyl group, R′ an atom of hydrogen or of chlorine, the chain between the two atoms of nitrogen of the lateral chain consists of 2 or 3 atoms of carbon (n=2.3) and it may be linear or branched with small groups of alkyls (R˝=hydrogen, methyl or ethyl); groups R‴ and RIV are CH₃ C₂H₅,
or they are part of a ring such as the one of pyrrolidine, of piperidine, of N-methylpiperazine, of β-hydroxyethylpiperazine or of morpholine.
