Oxyphenisatine

A stimulant laxative first obtained in 1885 by chemists Baeyer and Lazarus, by condensing isatin with phenol. A close relative of bisacodyl and phenolphthalein, it was withdrawn in most countries in the early 1970s. This family brings together the active ingredient and other impurities.

Did you know?In 1951 a molecule of the same family, a diphenylisatin, was reported in California prunes; today, however, the laxative effect of prunes is credited mainly to other components, such as sorbitol.
