摘要:
The present disclosure relates to steroid carboxylic acids and derivatives thereof. More particularly, the disclosure is concerned with D-homosteroid carboxylic acids and their derivatives, a process for the preparation thereof and pharmaceutical compositions containing same. The instant compounds are active endocrinal agents, especially as antiinflammatory agents.
摘要:
17.alpha.-hyroxy- and 17a.alpha.-hydroxy-D-homoetiocarboxylic acids of the formula ##STR1## wherein n is 1 or 2,A is ##STR2## and R.sub.1 is H or CH.sub.3are prepared by hydrating the corresponding 17-nitriles with a mixture of a lower carboxylic acid and its anhydride in the presence of perchloric acid. The resultant 17.beta.-N-acylcarboxamide is then treated with an alkali metal hydroxide in a polyhydric alcohol at an elevated temperature. The product acids are intermediates, e.g., for the production of steroids having antiinflammatory activity.
摘要:
The present disclosure is concerned with 9.alpha.-chloro-17-(m-iodobenzyloxy) steroids and a process for their manufacture. The subject compounds are useful as intermediates in the synthesis of pharmacologically-active substances and have themselves been found to exhibit pharmacological activity.
摘要:
The present invention is directed to 3-oxo, 6,9-hydro or halo, 11-oxo or (.alpha.--H,.beta.--OH), 17a-alkanoyloxy, 17a.beta.-carboxylate D-homosteroids which are useful as antiinflammatory agents.
摘要:
D-homopregnanes of the formula ##STR1## wherein R.sup.6 is hydrogen, chloro, fluoro or methyl; X is .beta.-hydroxymethylene or carbonyl; R.sup.17a is hydroxy, lower alkanoyloxy or aroyloxy; R.sup.21 is hydrogen, chloro, fluoro, hydroxy, lower alkanoyloxy, aroyloxy, sulfate or phosphate; and the dotted line in the 1,2-position of the A-ring denotes an additional carbon-carbon bondAnd pharmaceutically acceptable salts thereof, processes for the preparation thereof and pharmaceutical compositions containing them as the active ingredient are disclosed. The D-homopregnanes of the present invention exhibit hormonal activity and are useful for the treatment of inflammation.
摘要:
D-Homopregnanes of the formula ##STR1## wherein the dotted line in the 1,2-position together with the corresponding solid line denotes a single or double carbon-carbon bond; R.sup.6 is hydrogen, fluoro, chloro or methyl; R.sup.9 is hydrogen, fluoro, chloro or bromo; R.sup.11 is hydroxyl, acyloxy, fluoro or chloro; and R.sup.17a is hydroxyl or acyloxy with the proviso that when R.sup.9 is fluoro, chloro or bromo and R.sup.11 is fluoro or chloro, the atomic number of R.sup.11 is less than or equal to that of R.sup.9 ; and with the further proviso that when R.sup.6 is hydrogen, and R.sup.11 and R.sup.17a are hydroxy or when R.sup.6 is fluoro, R.sup.11 and R.sup.17a are hydroxyl and the dotted line in the 1,2-position together with the corresponding solid line denotes a single carbon-carbon bond, R.sup.9 is fluoro, chloro or bromo and processes for the preparation thereof are disclosed.
