BRD5529 is a selective CARD9-E3 ubiquitin ligase TRIM62 protein-protein interaction inhibitor with an IC50 of 8.6 μM. BRD5529 directly and selectively binds CARD9, disrupts TRIM62 recruitment, inhibits TRIM62-mediated ubiquitinylation and activation of CARD9, and demonstrates cellular activity and selectivity in CARD9-dependent pathways[1].
