Question

Terpene indole alkaloid derived from L-Tryptophan via secologanin is:

• A. Morphine
• B. Codeine
• C. Ajamalicine
• D. Thebaine

Answer 1

The Correct Option is C

The question pertains to the identification of a terpene indole alkaloid derived from L-Tryptophan via secologanin. Let's break down the solution step-by-step:

Understanding Alkaloids

Alkaloids are a class of naturally occurring organic compounds that mostly contain basic nitrogen atoms. They are known for their pharmacological effects and are primarily found in plants.

Terpene Indole Alkaloids

Terpene indole alkaloids are a group of alkaloids that originate from the amino acid L-Tryptophan and often involve a terpene moiety. The biosynthesis of these compounds involves a key intermediate known as secologanin, which is a monoterpene glycoside.

Analyzing the Options

1. Morphine: Morphine is an opiate alkaloid derived from the opium poppy. It is not synthesized from L-Tryptophan nor involves secologanin.
2. Codeine: Similar to morphine, codeine is also an opiate alkaloid. It does not derive from L-Tryptophan and does not fall under the category of terpene indole alkaloids.
3. Ajamalicine: Ajmalicine, also known as raubasine, is a terpene indole alkaloid. It is derived from L-Tryptophan and involves the intermediate secologanin, making it the correct answer.
4. Thebaine: Thebaine is another opiate alkaloid, related to morphine and codeine, and does not involve secologanin or L-Tryptophan.

Conclusion

The correct answer is Ajamalicine, as it is a terpene indole alkaloid derived from L-Tryptophan via secologanin. Understanding the biosynthetic pathways and structural components is crucial in determining the correct alkaloid.
