Selection Model in Drug Discovery: Tissue Targeting & Candidate Identification #3776159 (License: Personal Use)

The diagram outlines a dual-selection workflow: negative selection in healthy animals identifies molecules that avoid off-target binding, while positive selection in diseased models isolates molecules that specifically bind pathological tissue. Iterative rounds of administration, blood sampling, molecule propagation, and characterization refine candidates toward an ideal drug-non-toxic in healthy subjects and highly specific in diseased ones.

Used on biotech/pharma R&D webpages, educational platforms, or grant proposal materials to explain preclinical screening strategies; targets scientists, investors, and students seeking mechanistic insight into targeted drug development.
