Morphology

mercaptopurine = purine (opaque) = mercapto + purine

The prefix 'mercapto-' is a technical chemical combining form denoting a thiol substituent and is not interpretable by general learners, so the compound's meaning is not derivable from its parts for B1 learners.

Etymology

Mercaptopurine joins mercapto ('mercury-catching', a sulfur-containing part) and purine ('a basic part of DNA and RNA'). So mercaptopurine is a purine-like chemical with a sulfur group, which helps explain why the drug works by affecting purine metabolism in cells.
