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: ##STR1## 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.
本发明涉及具有抑制由于血红蛋白基因突变或寄生虫导致的红细胞形态异常或破坏作用的环状二硫代乙酰胺,其化学式为:##STR1## 其中X是直接键,氧原子或硫原子、亚甲基基团、乙烯基团或N--R基团,其中R是氢原子或较低的烷基、较低的(羟基)烷基、较低的烷酰基或苯基;其可能的药学上可接受的盐;从较低烷基的二硫代乙酸酯或巯基乙酸酯通过转氨作用和可能的氧化作用制备它们的方法;以及包含它们作为活性成分的制剂,用于例如镰状细胞病、疟疾和巴贝氏病的治疗。
