The L-arginine salts of the mercaptoethansulphonic acid are active in the therapy of the bladder carcinoma and in the therapy and prevention of the cistinic kidney calculi. The saline derivatives with basic aminoacids and their alkyl esters are moreover devoid of side effects. The latter derivatives are prepared by reacting, in aqueous or aqueous-alcoholic medium, equimolar amounts of mercaptoethansulphonic acid, just prepared from an organic or inorganic salt thereof, and of the desired aminoacid.
L-精氨酸盐对巯基乙烷磺酸在膀胱癌治疗和囊性肾结石治疗和预防中具有活性。碱性氨基酸及其烷基酯的盐类衍生物也没有副作用。后者的衍生物是通过在水或水醇介质中反应等摩尔量的刚刚从有机或无机盐中制备出来的巯基乙烷磺酸和所需氨基酸制备而成。
