Oxindole (2-indolone) is an aromatic heterocyclic organic compound. It has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered nitrogen-containing ring. Oxindole is a modified indoline with a substituted carbonyl at the second position of the 5-member indoline ring.
Oxindole is a tryptophan derivative and in human biology is formed by gut bacteria ("normal flora"). It is normally metabolized and detoxified from the body by the liver. In excess, it can cause sedation, muscle weakness, hypotension, and coma. Patients with hepatic encephalopathy have been recorded to have elevated serum oxindole levels. Recently, oxindoles, as the anticancer agents, have drawn wide attention. An interesting finding is that steroid-oxindole hybrids have shown excellent cytotoxicity against human cancer cell lines and can inhibit cell cycle and induce cell apoptosis.
