,Question 1
Which feature of a medicinal plant most directly motivates its
investigation as a potential source of therapeutic agents?
A. Its ability to produce compounds that interact with biological targets
B. Its ability to grow in multiple geographic regions
C. Its resistance to environmental stress
D. Its high concentration of carbohydrates
,Correct Answer: A. Its ability to produce compounds that interact with
biological targets
Rationale:
A is correct because natural products can contain chemically diverse
molecules with biological activity that may serve as therapeutic agents
or lead compounds. B is incorrect because geographic distribution does
not determine therapeutic potential. C is incorrect because
environmental resistance does not establish pharmacological activity. D
is incorrect because carbohydrate abundance does not by itself indicate
drug potential.
Question 2
A researcher isolates a previously unknown compound from a medicinal
plant and finds that it produces a reproducible biological effect in a
cellular assay. What is the most appropriate interpretation of this
finding?
A. The compound is automatically suitable for clinical use.
B. The compound may represent a lead for further drug development.
C. The compound has already demonstrated clinical efficacy.
D. The compound can be marketed as a drug without additional testing.
Correct Answer: B. The compound may represent a lead for further
drug development.
Rationale:
B is correct because an active natural product can serve as a lead
compound that requires additional characterization, optimization,
safety evaluation, and clinical development. A is incorrect because
, cellular activity does not establish suitability for clinical use. C is
incorrect because clinical efficacy requires evidence from appropriately
designed clinical studies. D is incorrect because extensive preclinical
and regulatory evaluation is required before marketing.
Question 3
What is the primary purpose of determining the chemical structure of a
newly identified natural product during drug discovery?
A. To establish whether the plant can be cultivated commercially
B. To understand the compound's chemical properties and guide further
optimization
C. To determine the patient's preferred route of administration
D. To predict the exact clinical dose without additional testing
Correct Answer: B. To understand the compound's chemical properties
and guide further optimization
Rationale:
B is correct because structural characterization helps researchers
understand chemical behavior, identify functional groups, compare
related compounds, and guide medicinal chemistry optimization. A is
unrelated to the pharmacological evaluation of the compound. C cannot
be determined from chemical structure alone. D is incorrect because
dose selection requires pharmacologic, toxicologic, pharmacokinetic,
and clinical data.
