1,3-dialkyl 3-phenylpyrrolidine-2, 5-diones were modified to produce potential steroid sulphatase inhibitors. These modifications were aimed at producing compounds, which could be expected to bind reasonably well to the active site of the steroid sulphatase enzyme but could not be hydrolyzed readily by the enzyme due to the covalent S-C bond present. In this regard the sulphinic acid deriv...

Steroid sulphatase deficiency is a recently recognised genetically determined inborn error of metabolism. Originally identified as an enzyme disorder of the placenta (commonly termed placental sulphatase deficiency), it is now known that the progeny of affected pregnancies have a generalised steroid sulphatase deficiency and that the enzyme defect persists throughout life. The disorder is chara...

HL60 promyeloid cells express both classes of oestrogen receptor (ERalpha and ERbeta). We show that hydrolysis of oestrone sulphate by steroid sulphatase is a major source of oestrone in HL60 cells, and that most of the released oestrone is not metabolized further to 17beta-oestradiol. Treatment of HL60 cells with retinoids or 1alpha,25-dihydroxyvitamin D3 increased steroid sulphatase mRNA and ...

bad, with variable results in between. Amputation of a digit is sometimes thought to produce a quicker return to work for the patient than replantation, but this is not borne out by published results."' The outlook in the leg is less clear. Functional results are often poor if a leg is replanted. Nevertheless, filleting may produce useful soft tissue which may be used as a vascularised free tra...

An infertile male patient with a 45,X peripheral blood karyotype and a 45,X/46,X,del(Y)(pter----q11.1:) mosaic skin fibroblast karyotype is described. Steroid sulphatase (STS) activity was normal. Recombinant DNA studies using Y chromosome specific probes suggest that almost the entire long arm of the Y chromosome is deleted.
