Compounds can be used to act as inhibitors of enzymes having histone deacetylase activity for the medical therapy of conditions which predispose a person for the development of a disease, such as but not limited to cancer, inflammatory or metabolic diseases. Such conditions are linked to genetically inherited mutations of crucial genes which predispose a person with this condition to develop the disease phenotype. Thus, such compounds can be used for a suppressive therapeutic approach—the SUPPRESSION THERAPY—in order to inhibit or delay the onset or progression of the genetically predisposed disorder. Furthermore, a clinically used medicament can be manufactured for the SUPPRESSION THERAPY of such inherited predisposing conditions.
