Isatin

Isatin, also known as tribulin, is an organic compound derived from indole with formula C8H5NO2. The compound was first obtained by Otto Linné Erdman and Auguste Laurent in 1840 as a product from the oxidation of indigo dye by nitric acid and chromic acids.

Isatin is a well-known natural product which can be found in plants of the genus Isatis, in Couroupita guianensis, and also in humans, as a metabolic derivative of adrenaline.

It looks like a red-orange powder, and it is usually employed as building block for the synthesis of a wide variety of biologically active compounds including antitumorals, antivirals, anti-HIVs, and antituberculars.

The isatin core is also responsible for the color of “Maya blue” and “Maya yellow” dyes.
