Druggability Rationale: ALOX5 is highly druggable (0.90 score) as a validated enzyme target with a well-characterized active site, demonstrated by 9 available crystal structures and the FDA-approved drug zileuton. The high-resolution structural data (1.98 Å) and multiple PDB complexes provide excellent templates for structure-based drug design, enabling optimization of potent and selective small molecule inhibitors targeting leukotriene synthesis.

Mechanism: Small molecule inhibitors blocking leukotriene synthesis

Selectivity & Safety Considerations

ALOX5 selectivity is achievable due to distinct structural features separating it from other lipoxygenase isoforms (ALOX12, ALOX15); however, off-target lipoxygenase activity should be monitored given the mechanistic overlap within the family. Zileuton's clinical validation demonstrates that selective ALOX5 inhibition is achievable without prohibitive cross-reactivity.
