    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.

    摘要: The use of etilefrin or etilefrin pivalate in the long term treatment of circulatory disorders not due to hypotonia, such as for example peripheral arterial stenoses, leads surprisingly to a continuous stable rise in systolic blood pressure and blood pressure amplitude and an improved cardiac output, without affecting the diastolic blood pressure or the cardiac frequency. The pharmaceutical effect is enhanced by using etilefrin in combination with an extract of horse chestnut seeds in a long term treatment.

    摘要: The preparation of the pure enantiomers of LIFIBROL and its alkyl esters is achieved with surprisingly good yield by reacting the pure enantiomeric forms of S(-) R(+)-4-(4-tert.butylphenyl)-1,2-epoxy butane with 4-hydroxybenzoic acid alkyl ester at elevated temperature in DMF and in the presence of 4-hydroxybenzoic acid alkyl ester sodium salt. Thereafter, the raw reaction product is separated. Either the stereochemically pure LIFIBROL ester is then recovered by recrystallization or the precipitated LIFIBROL enantiomer is made in pure crystalline form by mild alkaline saponification and subsequent acidification.
