ABSTRACT:
A human cataractous lens nuclei methanolic extract characterized in that it comprises substances having a molecular weight lower than 3000 daltons, inhibiting ATP hydrolysis by Na.sup.+,K.sup.+ -ATPase having affinity to the ouabain binding site on the enzyme and cross-reacting with an antibody directed against digoxin. Compounds of the general formula are disclosed: ##STR1## or of the general formula: ##STR2## in which R is hydrogen, an amino acid, a di- or tripeptide or a mono-, di- or trisaccharide. Pharmaceutical preparations and methods of using the compounds are also disclosed.
