Disclosed are novel 6-oxygenated-3,20-dioxo-pregnane derivatives of the general formula I
and specified 1,2-dihydroderivatives thereof. D is
,wherein Z represents specified acylgroups.
The other substituents of formula I include those commonly met in known corticosteroids.
The novel compounds may be prepared by methods known per se. The 6-acyloxy compounds of formula I are preferably prepared by subjecting a corresponding 6-oxo-compound of formula II, as herein defined, to esterification conditions. The 6-oxo-compounds of formula I are preferably prepared by oxidation of the corresponding 6-hydroxy-6,7-dihydro compounds. The novel compounds exhibit anti-inflammatory activity and are therefore useful in the treatment and control of inflammatory conditions.

The present invention relates to the selective conversion of 20-methylpregna-3,5,20(21)- triene-3,21-diol-diacetate to 3-oxo-20-methylpregna-4,20(21)- diene-21-yl-acetate by the use of a halogenated solvent and a halogenated acid. This process provides improved recovery of 3-oxo-20-methylpregna-4,20(21)- diene-21-yl acetate which is a useful intermediate in the preparation of progesterone.

Monoclonal antibodies (MAbs) have been developed to human cytochrome P450 2C8/9 (CYP2C8/9) by the fusion of myeloma tumour cells with isolated B-lymphocytes from spleens of mice immunised with baculovirus-expressed human CYP2C9; the MAbs for CYP2C9 are very powerful inhibitors of CYP2C8/9 activity and stray binders of the enzymes on Western blot and exhibit no cross-reactivity towards any of the other P450 subfamily members; based on these features the MAbs are useful tools for measuring CYP2C8/9 and assessing the role of CY2C8/9 in the metabolism of various compounds.
The invention relates to a sterile, ready-to-use, pharmaceutical oil-in water emulsion composition for parenteral administration comprising: 0.015 to 1.2% wt./vol. of progestogen; 0.5-30% wt./vol.oil, wherein the oil comprises at least 85% wt.wt. triglyceride; 0.0425-12.5% wt./vol phospholipid; 61.4-99.4% wt./vol. aqueous medium; wherein the phospholipid is present in an amount of 6.8% - 43% of the oil (wt./wt.), and wherein the progestogen is present in an amount greater than or equal to 2.1wt% of the oil, preferably greater than or equal to 2.2wt% of the oil. The invention further relates to the use of the aforementioned composition in therapeutic or prophylactic treatment, said treatment comprising intravenous administration of the pharmaceutical composition.
