摘要:
Stilbene derivatives having at least one further phenyl substituent in the para-position to a benzene ring in the stilbene are optical brighteners particularly suitable for incorporation on spinning masses.
摘要:
Monostyryl-1-naphthalenes and analogous compounds having a naphthalene, thiophene, furane or pyridine nucleus instead of the phenyl moiety of the styryl residue, which are obtained by the Horner synthesis, are useful as optical brighteners.
摘要:
SUBSTITUTED ALKENOIC ACIDS HAVING TWO PHENYL OR LOWER ALKOXYPHENYL GROUPS AND CERTAIN DERIVATIVES HAVE BEEN FOUND TO HAVE EXTROGENIC, E.G., ANTI-FERTILITY PROPERTIES FOR TREATING MENOPAUSAL DISORDERS OR FOR ESTROGENIC REPLACEMENT. TYPICAL COMPOUNDS ARE 2-CARBOXY-5,5-DIPHENYL-4METHYLPENT--4-ENOIC ACIDS, 2-METHYL-4-ETHYL-5,5-DIPHENYL2-CARBOXYPENT-4-ENOIC ACID AND 2,4-DIMETHYL-5-PHENYL5-(4-METHOXY-PHENYL)PENT-4-ENOIC ACID. THE NEW COMPOUNDS ARE FORMULATED AS TABLETS AND CAPSULES FOR ORAL USE AND AS INJECTABLE WITH STERILE WATER,
摘要:
Substituted phenyl acetic acids e.g. p-(1-t-butyl vinyl) phenyl acetic acids are prepared by dehydrating corresponding (ppivaloyl phenyl) acetic acids and are useful as hypolipidemic agents.
摘要:
5-Oxa phenyl- and phenoxy-substituted prostaglandin-type compounds and processes for making them. These compounds are useful for a variety of pharmacological purposes, including antiulcer, inhibition of platelet aggregation, increase of nasal patency, labor inducement at term, and wound healing.

Benzyl esters and thiolesters of 4-aryl-3-butenoic acids, intermediates therefor, synthesis thereof, and the use of said esters and thiolesters for the control of pests.
摘要:
A compound of the formula (1) ##STR1## in which X and X' stand for an optionally functionally modified carboxy or sulfo group and wherein the naphthalene nuclei may carry further non- chromophoric substituents and a process for their preparation. These compounds are valuable optical brighteners and can be applied by the methods known in this field.
