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 a sulphamate group of the formulawherein each of R1and R2is independently selected from H, alkyl, alkenyl, cycloalkyl and aryl, or together represent allylene 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 Kmvalue of less than 50 μM.
