The 13 pages that link to Indole, each with the reason it gives.

• Heterocyclic compoundBroader topic: Its fused framework shows how a heterocycle can share aromaticity with a carbocycle.

• TryptophanRelated: Tryptophan's bulky indole side chain gives it distinctive chemical and protein interactions.

• PyrroleRelated: Indole embeds a pyrrole-like nitrogen ring in the structures of tryptophan and many natural products.

• EumelaninNarrower topic: Indole-derived structures form much of eumelanin’s complex polymer framework.

• BenzimidazoleCompared with: It has a similar fused framework but a pyrrole ring instead of imidazole.

• Fused ringBroader topic: This fused heterocycle occurs in tryptophan and many bioactive compounds.

• Indole-3-acetic acidNarrower topic: IAA contains an indole group, which gives the molecule its name and chemical scaffold.

• TryptamineRelated: Tryptamine consists of this fused-ring scaffold attached to an ethylamine side chain.

• CarbazoleCompared with: Like carbazole, it fuses benzene to a nitrogen-containing ring, but has only one benzene ring.

• IsoquinolineCompared with: Its fused nitrogen ring is five-membered, unlike isoquinoline’s six-membered ring.

• SkatoleCompared with: Indole lacks skatole's methyl substituent and has a distinct odor.

• Anthranilic acidRelated: Tryptophan biosynthesis transforms anthranilate-derived material into the indole framework.

• BenzofuranCompared with: Replacing furan’s oxygen with pyrrole’s nitrogen gives a closely related fused-ring framework.
