摘要:
Estrane derivatives of the general formula I ##STR1## wherein one of the substituents X or Z signifies a hydrogen atom and the other together with Y represents a carbon-carbon bond, or wherein the substituents X and Z represent hydrogen atoms and Y represents an .alpha.-position hydroxy group or a .beta.-position alkyl group with up to 6 carbon atoms, are valuable intermediates for preparation of pharmacologically effective substances.
摘要:
The invention relates to the 1.beta., 15.alpha.-dihydroxy-1.alpha.-methyl-5.alpha.-androstane-3,17-dione of formula I ##STR1## and preparation thereof using microorganisms of the genera Glomerella or Fusarium. The invention also relates to further processing of the compound of formula I to obtain pharmacologically effective steroids.
摘要:
6.alpha.-methylhydrocortisones of Formula I ##STR1## wherein R.sub.1 is alkanoyl of 2-6 carbon atoms or benzoyl andR.sub.2 is hydrogen or alkanoyl of 2-6 carbon atomshave valuable antiinflammatory properties.
摘要:
6.alpha.-Methylprednisolone derivatives of Formula I ##STR1## wherein R.sub.1 is 1-oxoalkyl of 2-6 carbon atoms or benzoyl andR.sub.2 is 1-oxoalkyl of 2-6 carbon atoms, are pharmacologically efficacious compounds, e.g., as antiinflammatories.
摘要:
11.beta.-Chloro-.DELTA..sup.15 -steroids of Formula I ##STR1## wherein R.sup.1 is hydrogen or acyl andR.sup.2 is ethynyl, chloroethynyl, or propynyl have strong progestational activity.
摘要:
11-Methylene-.DELTA..sup.15 -steroids of Formula I ##STR1## wherein R.sup.1 is hydrogen or acyl andR.sup.2 is ethynyl, chloroethynyl or propynyl,are distinguished by a strong progestational activity and exhibit only a very low androgenic side effect.
摘要:
Novel corticoid 17-thioacetals of the formula: ##STR1## wherein X is hydrogen, fluorine or methyl,R.sub.1 is hydrogen or C.sub.1 -C.sub.6 alkyl, andR.sub.2 is hydrogen or the acyl group of a C.sub.1-16 - hydrocarbon carboxylic acid,have valuable medicinal properties, e.g., as antiinflammatories.
摘要:
A cleaning implement for damp cleaning of surfaces using mopping water includes a first plastic element which indicates the temperature of the mopping water by a reversible change in its color upon contact with the mopping water.
摘要:
This invention describes new, substituted 7.alpha.-(.xi.-aminoalkyl)-estratrienes of general formula I ##STR1## in which side chain SK is a radical of partial formula ##STR2## as well as their physiologically compatible addition salts with organic and inorganic acids.The new compounds represent compounds with very strong antiestrogenic action.The compounds according to the invention are, on the one hand, pure antiestrogens, or, on the other hand, antiestrogens with estrogenic partial action. Based on this spectrum of action, the new compounds are highly suitable for the production of pharmaceutical agents for tumor therapy and hormone replacement treatment.
摘要:
Known pregnane derivatives are prepared by esterificiation of known androstane derivatives to give new ester of Formula III ##STR1## wherein in each case symbolizes a single bond or a double bond,n is 1 or 2,R.sub.1 is hydrogen or methyl,R.sub.2 is hydrogen or formyl, andR.sub.3 is chlorine, hydroxy or an alkanoyloxy group of up to 6 carbon atoms,and reaction of the latter with Ag(I) and formic acid.
