About These Diagrams

Every diagram in this library was created exclusively for CompoundReview. Each mechanism diagram traces the step-by-step signaling pathway from receptor binding through downstream cellular effects, using the site's navy and gold design language for visual consistency. Comparison charts place two or three compounds side-by-side at the receptor level, making it easy to identify where pathways converge and diverge.
