| 16 alpha-hydroxyprogesterone dehydratase | <enzyme> From rat intestinal anaerobic bacteria; forms 16-dehydroprogesterone Registry number: EC 4.2.1.- Synonym: 16 alpha-dehydratase (26 Jun 1999) |
|---|---|
| 17a-hydroxyprogesterone | 17a-Hydroxy-4-pregnen-3,20-dione;medical use is similar to that of progesterone. The acetate is an orally effective derivative, useful in conditions in which parenterally administered progesterone or the caproate is indicated; it possesses some androgenic potency and may cause virilizing changes in a female foetus. The caproate or hexanoate has essentially the same actions and uses as progesterone, but is more potent and has a longer duration of action. A precursor of the androgens and adrenocortical hormones.

| 17 alpha-hydroxyprogesterone aldolase | <enzyme> An enzyme of the lyase class that catalyses the cleavage of the bond between carbons 17 and 20 in 17-alpha hydroxyprogesterone to form delta 4-androstene-3,17-dione, an androgen. It also catalyses the conversion of 17 alpha-hydroxypregnenolone to dehydroepiandrosterone. Chemical name: 17 alpha-hydroxyprogesterone acetaldehyde-lyase Registry number: EC 4.1.2.30 (12 Dec 1998) |
| 17-hydroxyprogesterone | A hydroxyprogesterone with medical uses similar to that of progesterone. (12 Dec 1998) |
| 21-hydroxyprogesterone | 11-Deoxycorticosterone; 21-hydroxypregn-4-ene-3,20-dione;an adrenocortical steroid, principally a biosynthetic precursor of corticosterone and possibly aldosterone, that rarely appears in adrenocortical secretions; a potent mineralocorticoid with no appreciable glucocorticoid activity. Synonym: 21-hydroxyprogesterone, cortexone, deoxycortone, desoxycortone. Deoxycorticosterone acetate, desoxycorticosterone acetate;acetate salt used for intramuscular injection for replacement therapy of the adrenocortical steroid. Deoxycorticosterone pivalate, desoxycorticosterone pivalate;pivalate salt of the steroid. (05 Mar 2000) |
