摘要

The present invention relates to cyclic dithiodiacetamides with action inhibiting the malformation or the destruction of the red blood corpuscles due to a genetic modification of the haemoglobin or to parasites, of formula: <IMAGE> in which X is a direct bond, an atom of oxygen or of sulfur, a methylene group, an ethylene group or an N-R group, where R is an atom of hydrogen or a lower alkyl group, lower (hydroxy)alkyl group, lower alkanoyl group or a phenyl group; to their possible pharmaceutically acceptable salts; to a process for preparing them from a dithiodiacetate or a mercaptoacetate of lower alkyl by transamination and possible oxidation; and to pharmaceutical compositions containing them as active ingredients, useful for the treatment for example of drepanocytosis, or sickle cell anaemia, of malaria and of babebiosis.
