,1. Which statement best describes the historical role of
medicinal plants in drug discovery?
A. They primarily provided inactive placebo compounds
B. They served as direct sources of pharmacologically active
molecules
C. They were used mainly to validate synthetic drug libraries
D. They contributed only to toxicology research
Correct Answer: B
Rationale:
Goodman & Gilman describes medicinal plants as foundational
sources of bioactive compounds that directly led to the
discovery of many therapeutic agents.

Plants to Computer-Aided Drug Design
2. Which limitation of natural products is emphasized as a
challenge in modern drug development?
A. Lack of biological activity
B. Structural simplicity
C. Difficulty in large-scale synthesis and standardization
D. Inability to interact with human receptors
Correct Answer: C
,Rationale:
The chapter highlights challenges such as complex structures
and difficulties in synthesis and reproducibility when developing
drugs from natural products.

3. What is the primary goal of lead compound optimization?
A. Eliminate all adverse effects
B. Improve potency, selectivity, and pharmacokinetic properties
C. Reduce molecular weight below a fixed threshold
D. Ensure complete receptor antagonism
Correct Answer: B
Rationale:
Lead optimization focuses on enhancing efficacy, selectivity, and
drug-like properties while minimizing toxicity, as described in
the drug discovery process.
Citation:

4. Which term refers to a compound that shows desirable
biological activity but requires modification before clinical
use?
, A. Prodrug
B. Lead compound
C. Biomarker
D. Excipient
Correct Answer: B
Rationale:
A lead compound is identified during screening as having
promising activity and serves as the starting point for further
chemical refinement.
Citation:
Goodman & Gilman, 14th ed., Drug Discovery chapter
5. High-throughput screening (HTS) is best described as:
A. Manual testing of compounds in animal models
B. Computational prediction of drug–receptor binding
C. Automated testing of large compound libraries against
biological targets
D. Post-marketing surveillance of adverse drug reactions
Correct Answer: C
Rationale:
The chapter defines HTS as an automated method allowing
rapid evaluation of thousands of compounds for biological
activity.
