摘要:
The invention relates to a 11-(substituted phenyl)-estra-4,9-diene derivative of formula I ##STR1## wherein A, X, R.sub.1 and R.sub.2 are as defined by the specification. The compounds of the invention have anti-glucocorticoid activity and can be used in treating or preventing glucocorticoid-dependent diseases.
摘要:
The invention relates to novel 4-azaandrostene intermediates of formula (I), ##STR1## wherein R is hydrogen or a C.sub.1-3 alkyl group;X is chlorine, bromine or iodine; and the---- bond line is a single or double bond.
摘要:
The invention includes compounds of formula (I): ##STR1## in which R.sup.1 is hydrogen, alkyl, aryl-substituted alkyl or aromatic heterocyclic-substituted alkyl; R.sup.2 is aryl-substituted alkyl, aromatic heterocyclic-substituted alkyl or diarylamino; and R.sup.3 is carboxy or a group of formula --CONHSO.sub.2 R.sup.4 wherein R.sup.4 is alkyl; and pharmaceutically acceptable salts and esters of the compounds. The compounds have valuable 5.alpha.-reductase inhibitory activity and can thus be used for the treatment and prophylaxis of, inter alia, prostatic hypertrophy as well as other disorders arising from excess levels of 5.alpha.-dihydro-testosterone.
摘要:
8-En-19,11.beta.-bridged steroids of general formula I ##STR1## that have the 8,9-double bond as a new structural feature, and a process for their production are described. The substituents R.sup.1 R.sup.4 -Y, R.sup.4' -Y.sup.', X and Z have the meaning indicated in the description. The new compounds especially have at their disposal pronounced antigestagen effectivenss and are suitable for the production of pharmaceutical preparations.

摘要:
A method of treating topical inflammation in mammals by the administration of 16.alpha.,17.alpha.-cyclopentylidenedioxy-9.alpha.-fluoro-11.beta.,21-dihydroxy-1,4-pregnadiene-3,20-dione 21-acetate in a pharmaceutically acceptable carrier.
摘要:
A process is disclosed for making 17-monoesters of 17 .alpha., 21-dihydroxy steroids by acylating a 17 .alpha., 21-dihydroxy steroid phosphate and then subjecting the intermediate 17-acyloxy-21-phosphate to dephosphorylation using an acid phosphatase to achieve enzymatic hydrolysis. Several new 17-monoesters having an anti-inflammatory property are also disclosed.
摘要:
Novel steroid compounds are provided represented by the formula: ##SPC1##Wherein each of R.sup.1 and R.sup.2 represents hydrogen or methyl group or R.sup.1 and R.sup.2 may be combined with each other to represent methylene group, n is 2 or 3 and the dotted line means a double bond at 6-exo-position when n is 2 or between 6- and 7-position when n is 3.These novel compounds show a strong anti-androgenic activity, especially by oral administration, and can be used as a remedy for the prostatomegaly.
