Oxyphenisatine (or oxyphenisatin) is a laxative.[3] It is closely related to bisacodyl, sodium picosulfate, and phenolphthalein. Long-term use is associated with liver damage,[4] and as a result, it was withdrawn in most countries in the early 1970s. The acetate derivative oxyphenisatine acetate was also once used as a laxative.

Natural chemical compounds similar to oxyphenisatine may be present in prunes,[5] but a recent review of the relevant scientific literature suggests that the laxative effect of prunes is due to other constituents including phenolic compounds (mainly neochlorogenic acids and chlorogenic acids) and sorbitol.[6] Oxyphenisatin has cathartic properties.

Synthesis

[edit]

The ketone group of isatin (1) is nonenolizable and has interesting properties. In strong acid it becomes protonated, and the oxygen can be replaced by electron rich moieties.

Oxyphenisatin synthesis:[7]

In 1885, it was reported that condensation of isatin with phenol 2 leads to oxyphenisatin (3), which can then also be acetylated to (4).

Derivatives

[edit]
  1. Phenisatin (Triacetyldiphenolisatin, Laxagetten, Unilax, Trisatin)
  2. Nicoxyphenisatin
  3. Cinnoxyphenisatin
  4. Cofisatine [54063-34-2]
