What is the derivative of indole?
What is the derivative of indole?
Tryptophan is a significant indole derivative while serotonin and melatonin are biochemically active indole molecules. There are also many indole alkaloid derivatives found in nature. The plant hormone Auxin contains indol-3-acetic acid. Furthermore, there are many important indole derivatives used in treatment.
Which drug contain indole derivative?
Indole ring containing drug molecules. Yohimbine: Drug for male impotency. Delavirdine: Anti-HIV drug. Apaziquone as anticancer, Oxypertine as antipsychotic and Arbidol as antiviral.
Why is indole not a base?
Basicity. Unlike most amines, indole is not basic: just like pyrrole, the aromatic character of the ring means that the lone pair of electrons on the nitrogen atom is not available for protonation. Strong acids such as hydrochloric acid can, however, protonate indole.
Is mefenamic acid indole derivatives?
Thus a series of mefenamic acid based indole derivatives were designed via a rational approach. Their design was prompted by the literature report on anticancer properties of mefenamic acid. Synthesis of this class of compounds was carried out via a 3-step method starting from the mefenamic acid.
Which of the following drug is an indole derivative Mcq?
Example of indole derivative drugs are indomethacine. ASA comes under salicylates. phenylpropionic acids e.g., ibuprofen, ketoprofen, pyrazalone derivatives e.g., phenylbutazone, disease modifying drugs: e.g. chloroquine.

What is an example of indole alkaloids?
Two plants that contain indole alkaloids are Passiflora incarnata L. (passion flower) and Mitragyna speciosa (Korth.) Havil (kratom), while the other two plants that did not show the presence of indole alkaloids are Piper methysticum G. Forst (kava) and Valeriana officinalis L., deserve special attention.
Which position of indole is reactive?
As shown in Scheme 1, indole is reactive at four different positions including the carbon atom 3, nitrogen atom 1, the C2–C3 π-bond and the C2–N sigma bond. Indole can be protonated with strong acids such as hydrochloric acid, which protonates the C3 position, more easily than the N atom.
Which of the following NSAIDs is an indole derivative?
