Reaction of androst-5-en-17-one (1) with hypobromous acid using a short reaction time (30 min) along with a careful isolation procedure gave, for the first time, the addition product, 5 alpha-bromo-6 beta-hydroxyandrostan-17-one (3), in 43% yield. This bromohydrin was much more

To verify the aldosterone amplifying action of 19-hydroxyandrostenedione (19-OH-AD), we investigated [3H]aldosterone and [3H]19-OH-AD binding to type I (mineralocorticoid) receptor in the renal cytosol of adrenalectomized and ovariectomized rat, and human mononuclear leucocytes (MNL). In the [3H]aldosterone binding study, the

Diabetes complicates 2-3% of all pregnancies and is associated with an increase in both perinatal morbidity and mortality, though reasons for these adverse outcomes are unknown. Estrogen biosynthesis is a critical factor during pregnancy and is carried out in the

Because of the association of preeclampsia with hydatidiform mole, and since levels of 19-hydroxyandrostenedione (19-OH-A) and androstenedione (A) are raised in hypertensive diseases of pregnancy, we compared plasma 19-OH-A and A in hydatidiform mole patients with control early pregnant women.
Aromatase activity in the foetal rat testis was demonstrated by the conversion of [3H] testosterone into oestradiol. However, the conversion rate was low, around 0.06%, probably because the radioactive precursor was heavily diluted by the large amounts of endogenous testosterone
