A research team is working on the design of a new drug for the treatment of lung cancer. To be most effective, this drug must specifically enter the cytoplasm of lung cells while not entering the cells of other tissues. Which of the following characteristics would likely enhance the specificity of this drug?
A) the relative hydrophobicity of the drug molecule
B) phospholipid composition of lung cell plasma membranes
C) specificity of the drug molecule for binding to the extracellular matrix of lung cells
D) similarity of the drug molecule to other molecules normally transported lung cells

Question

Quizplus · Accepted Answer

The similarity of the drug molecule to other molecules normally transported into lung cells would enhance specificity, as it could utilize existing transport mechanisms specific to lung cells.
