摘要:
The invention relates to p-oxibenzoic acid derivatives of the general formula (1) where: ##STR1## their diastereomers and enantiomers in pure form or as mixture of stereoisomeric forms and their physiologically compatible salts, a process for the preparation thereof and the use thereof for preparing drugs with hypolipemic effect.
摘要:
Para substituted benzoic acid derivatives of general formula (1) ##STR1## and their physiologically compatible salts, where R.sup.1 may be H, isopropyl, t-butyl p0 X may be ##STR2## and R.sup.2 may be --OH, --OR', where R' is a linear or branched, saturated or unsaturated C.sub.1 to C.sub.3 alkylmoiety, or a --NHCH.sub.2 COOH-- group, have hypolipedemic activity. They may be obtained by known methods either from the corresponding unsaturated ketones or from saturated hydroxycompounds, where the esterified benzoic acid moiety may be saponified or converted to a carboxymethylamide.

摘要:
P-oxybenzoic acid derivatives of formula (1) ##STR1## wherein R.sup.1 is hydrogen, or straight or branched alkyl of one to four carbon atoms;n is 1 or 2;X is ##STR2## and R.sup.2 is --OH or --NHCH.sub.2 COOH; and non-toxic pharmaceutically acceptable salts thereof.The compounds exhibit a hypolipemic effect. They may be prepared by methods known in themselves from the corresponding ester or acid halide compounds, wherein optionally the secondary alcohol group may be oxidized to a keto group.

摘要:
Compounds of the formula ##STR1## wherein R.sup.1 is Cl, Br, CH(CH.sub.3).sub.2 or C(CH.sub.3).sub.3 ; A is a single bond, --CH.dbd.CH-- or --CH.sub.2 --CH.sub.2 --; and R.sup.2 is H, the cation of a pharmaceutically acceptable salt or an alkyl of up to three carbons, are strong hypolipaemic agents.
摘要:
Novel (E)-1-[4'-(2-alkylaminoethoxy)phenyl]-1- (3'-hydroxyphenyl)-2-phenylbut-1-enes of the general formula ##STR1## wherein R.sup.1 and R.sup.2 may be the same or different, provided that, when R.sup.1 and R.sup.2 are the same, each of them is a methyl or ethyl radical, and when R.sup.1 and R.sup.2 are different, one of them is hydrogen and the other is a methyl or ethyl radical, and the therapeutically compatible salts thereof, have a marked anti-estrogenic effect and are suitable for treating hormone-dependent mammary tumors.The compounds can be prepared by dehydrating carbinols of the general formula ##STR2## wherein R.sup.1 and R.sup.2 may be the same or different, provided that, when R.sup.1 and R.sup.2 are the same, each of them is a methyl or ethyl radical, and when R.sup.1 and R.sup.2 are different, one of them is a benzyl radical and the other is a methyl or ethyl radical; and wherein R.sup.3 is hydrogen or an easily hydrolyzable protecting group, through the action of mineral acid while removing any protecting group present, isolating through crystallization the E-form from the pair of isomers obtained, and removing by hydrogenolysis any benzyl group present.Compositions comprising the subject 1,1,2-triphenylbut-1-ene derivatives are described also. The corresponding novel 1,1,2-triphenylbut-1-ene derivatives having the (Z) configuration are also disclosed.
