scope, and concepts presented in this chapter only.
,Chapter 1 — Drug Discovery: From Medicinal Plants to
Computer-Aided Drug Design
Goodman & Gilman, 14th Edition
1. Which historical observation most directly contributed to
the early development of pharmacology as a scientific
discipline?
A. Systematic synthesis of chemical libraries
B. Identification of receptor subtypes
C. Empirical use of medicinal plants for therapeutic effects
D. Development of randomized clinical trials
Correct Answer: C
Rationale: Early pharmacology evolved from empirical
observations of therapeutic effects of natural substances,
especially medicinal plants, before molecular targets were
understood.
Citation: Goodman & Gilman, 14th ed., Chapter 1 – Drug
Discovery: From Medicinal Plants to Computer-Aided Drug
Design
2. Which characteristic best defines a “lead compound” in
drug discovery?
A. It is already approved for clinical use
B. It demonstrates desired biologic activity but requires
,optimization
C. It has maximal potency and no toxicity
D. It is produced exclusively by recombinant technology
Correct Answer: B
Rationale: A lead compound shows promising biologic activity
and serves as a starting point for chemical modification to
improve efficacy and safety.
Citation: Goodman & Gilman, 14th ed., Chapter 1
3. Which process involves systematic modification of a
compound to improve selectivity and potency?
A. High-throughput screening
B. Structure–activity relationship analysis
C. Pharmacovigilance
D. Bioequivalence testing
Correct Answer: B
Rationale: Structure–activity relationship (SAR) analysis
examines how chemical structure influences biologic activity to
guide rational drug optimization.
Citation: Goodman & Gilman, 14th ed., Chapter 1
4. High-throughput screening is best described as:
A. Clinical testing in large patient populations
B. Evaluation of drug safety after approval
, C. Rapid testing of large numbers of compounds against
biological targets
D. Computer modeling of receptor binding
Correct Answer: C
Rationale: High-throughput screening allows rapid
experimental evaluation of thousands of compounds for activity
at a biological target.
Citation: Goodman & Gilman, 14th ed., Chapter 1
5. Which advantage of natural products is emphasized in early
drug discovery?
A. Predictable pharmacokinetics
B. Structural diversity with biologic activity
C. Minimal adverse effects
D. High oral bioavailability
Correct Answer: B
Rationale: Natural products offer complex structural diversity
that has historically yielded biologically active compounds.
Citation: Goodman & Gilman, 14th ed., Chapter 1
6. Computer-aided drug design primarily relies on which
principle?
A. Empirical dosing in humans
B. Random compound synthesis
