Question

The source for synthesis of psoralen is _______

• A. \( \text{Coumarin} \)
• B. \( \text{Terpene} \)
• C. \( \text{Warfarin} \)
• D. \( \text{Diosgenin} \)

Hint:

Remember that psoralen is a furocoumarin. The "coumarin" part of "furocoumarin" should hint at its biosynthetic origin.

Answer 1

The Correct Option is A

Psoralen is a naturally occurring furocoumarin compound. Furocoumarins, including psoralen, are biosynthesized through a pathway that involves coumarin derivatives. Specifically, psoralen is formed by the addition of an isoprene unit to a coumarin precursor followed by cyclization.
