Question

Name the following drug molecule:

• A. Mechlorethamine
• B. Chlorambucil
• C. Vincristine
• D. 6-Mercaptopurine

Hint:

- Mechlorethamine is an alkylating agent used in chemotherapy. - The presence of two chlorine atoms attached to nitrogen is a key feature of its structure. - Chlorambucil and 6-Mercaptopurine have different chemical structures and uses.

Answer 1

The Correct Option is A

The structure shown is that of Mechlorethamine, which is an alkylating agent commonly used in chemotherapy. It contains two chlorine atoms (Cl) attached to the nitrogen of an ethylene diamine group. This chemical structure is characteristic of Mechlorethamine, also known as Mustine, which is used in the treatment of various cancers, including lymphomas and leukemias. 

Why Other Options Are Incorrect: 
- (B) Chlorambucil: Although Chlorambucil is also an alkylating agent, its structure differs by having an aromatic ring and a different substitution pattern compared to Mechlorethamine. 
- (C) Vincristine: Vincristine is a vinca alkaloid used in chemotherapy but has a completely different structure, containing a complex ring system. 
- (D) 6-Mercaptopurine: 6-Mercaptopurine is a purine analog, not an alkylating agent, and its structure does not resemble the one shown. 

Thus, the correct drug name for the given structure is Mechlorethamine.
