Structure-activity relationships were studied in vitro on a number of natural and artificial steroids in order to assess their progestagen specificity. These substances included a new compound derived from 19 nor progesterone, TX066 or nomegestrol acetate, and two synthetic intermediates

Estrogen receptors of human endometrial cancer Ishikawa cells were found to be present in moderate amounts (160-200 fmol/mg protein), and to specifically bind moxestrol (R2858) with a very high affinity characterized by a Kd around 60 pM, when measured under

Five synthetic progestins of the 19-nortestosterone type (norethisterone, NET; levonorgestrel, LN; gestodene, GEST; NET-3-oxime, NETO; norgestimate, NGM) were investigated in the in vitro hepatocyte model. Radiolabelled progestins were added to hepatocyte suspensions (3 x 10(6) cells/ml) freshly prepared from female
19-Nor-corticosteroids are potentially important mineralocorticoids and hypertensive agents. We tested the mineralocorticoid potency of 19-nor-progesterone (19-NOR-P) and 19-nor-corticosterone (19-NOR-B) compared with aldosterone using the toad bladder short-circuit current as a measure of sodium transport. 19-NOR-B (10(-7) M) increased sodium transport
The mineralocorticoid potency of 19-nor-progesterone was evaluated by both its effect on electrolyte excretion in adrenalectomized animals and its ability to cause hypertension and electrolyte changes in mononephrectomized, salt-loaded rats. The mineralocorticoid activity, measured using an adrenalectomized rat bioassay, indicated
