The following structure represents: a) Thioguanine, b) Thymidine, c) Mercaptopurine, d) Methotrexate. 5. Which of the following statements about amino group is false: a) It could act as HBD and HBA, b) Amide analogue is essential, c) Interaction through hydrogen bonding, d) Aromatic amines could act only as HBD.
Understand the Problem
The question is asking to answer a series of multiple-choice questions related to pharmacology and chemistry concepts, indicating the knowledge required in these subjects.
Answer
["1. b) Resorcinol","2. a) The aromatic ring is essential","3. d) Hydrogen bonding only","4. c) Mercaptopurine","5. b) Amide analogue is essential"]
["1. b) Resorcinol is not bactericidal.","2. a) The aromatic ring is essential.","3. d) Hydrogen bonding only.","4. c) Mercaptopurine.","5. b) Amide analogue is essential."]
Answer for screen readers
["1. b) Resorcinol is not bactericidal.","2. a) The aromatic ring is essential.","3. d) Hydrogen bonding only.","4. c) Mercaptopurine.","5. b) Amide analogue is essential."]
More Information
Bactericidal drugs kill bacteria directly, whereas sulphonamides require specific structural features to be active. Alcohols primarily engage in hydrogen bonding, while the structure shown is characteristic of mercaptopurine. The amide analogue statement about amino groups is false.
Tips
Misidentifying the drug actions or structural requirements can lead to incorrect answers.
