Abstract: A method of inhibiting steroid sulphatase activity in a subject in need of same is described. The method comprises administering to said subject a steroid sulphatase inhibiting amount of a ring system compound; which ring system compound comprises a ring to which is attached sulphamate group of the formula
wherein each of R1 and R2 is independently selected from H, alkyl, alkenyl, cycloalkyl and aryl, or together represent alkylene optionally containing one or more hetero atoms or groups in the alkylene chain; and wherein said compound is an inhibitor of an enzyme having steroid sulphatase activity (E.C.3.1.6.2); and if the sulphamate group of said compound is replaced with a sulphate group to form a sulphate compound and incubated with a steroid sulphatase enzyme (E.C.3.1.6.2) at a pH 7.4 and 37° C. it would provide a Km value of less than 50 &mgr;M.

Abstract: This invention describes a safe method for the production of sulfamoyl chloride from chlorosulfonyl isocyanate and formic acid in the presence of a amide catalyst, taming the hazardous nature of this reaction by circumventing heat accumulation processes, as well as the sulfamoylation of alcohols and phenols with the resulting sulfamoyl chloride in N,N-dimethyl acetamide or N-methyl pyrrolidone thereby avoiding the formation of side-products which were inevitable with the methods of the prior art using dimethyl formamide or dichloromethane as a solvent. The current invention allows industrial scale applications and describes as an example the process of manufacture of the biologically active compound 17&bgr;-Hydroxyestra-1,3,5(10)-triene-3-yl sulfamate.
