This molecule comprises the bicyclic indole framework (a six-membered benzene ring fused to a five-membered ring containing one nitrogen). The nitrogen in the five-membered ring is substituted by a hydroxyl group. On the same five-membered ring, the carbon adjacent to the nitrogen (position 2 relative to N) bears a carboxymethyl substituent (-CH2-COOH). There is no additional stereochemistry to specify.
