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].

Preclinical and Toxicology Studies of BRD5529, a Selective Inhibitor of CARD9
Drugs R D 2022 Jun;22(2):165-173.PMID:35486318DOI:10.1007/s40268-022-00389-0.
Background: The caspase recruitment domain-containing protein 9 (CARD9) inhibitor BRD5529 has been shown to be an effective in vitro inhibitor of Pneumocystis β-glucan-induced proinflammatory signaling, suggesting its viability as a candidate for preliminary anti-Pneumocystis drug testing in the rodent Pneumocystis pneumonia (PCP) model. Methods: Mice were injected intraperitoneally (IP) daily with either vehicle or BRD5529 at 0.1 or 1.0 mg/kg for 2 weeks. Mouse weights were taken daily. At day 14, mice were euthanized, weighed, and analyzed by flexiVent™ for lung stiffness. Lungs, liver, and kidney were then harvested for hematoxylin and eosin (H&E) staining and pathology scoring. Lung samples were further analyzed for proinflammatory cytokines via enzyme-linked immunosorbent assay (ELISA) and extracellular matrix generation via quantitative polymerase chain reaction (qPCR). Blood collection postmortem was performed for blood chemistry analysis. Furthermore, administration of BRD5529 prior to the intratracheal inoculation of fungal β-glucans, which are known proinflammatory mediators via the Dectin-1-CARD9 pathway, resulted in significant reductions in lung tissue interleukin-6 and tumor necrosis factor-α, suggesting the exciting possibility of the use of this CARD9 inhibitor as an additional therapeutic tool in fungal infections. Results: BRD5529 at both IP doses resulted in no significant changes in daily or final weight gain, and analysis of lung stiffness by flexiVent™ showed no significant differences between the groups. Furthermore, ELISA results of proinflammatory cytokines showed no major differences in the respective groups. qPCR analysis of extracellular matrix transcripts were statistically similar. Examination and pathology scoring of H&E slides from lung, liver, and kidney in all groups, as well as subsequent pathology scoring, showed no significant change. Blood chemistry analysis revealed similar, non-significant patterns. Conclusions: In our initial general safety and toxicology assessments, BRD5529 displayed no inherent safety concerns in the analyzed parameters. These data support broader in vivo testing of the inhibitor as a timed adjunct therapy to the deleterious proinflammatory host immune response often associated with anti-Pneumocystis therapy.
CARD9 mediates glucose-stimulated insulin secretion in pancreatic beta cells
Biochem Pharmacol 2021 Oct;192:114670.PMID:34233162DOI:10.1016/j.bcp.2021.114670.
Caspase recruitment domain containing protein 9 (CARD9) plays key regulatory role(s) in innate and adaptive immune responses. Recent evidence implicates CARD9 in the onset of metabolic diseases including insulin resistance. However, potential contributory roles of CARD9 in glucose-stimulated insulin secretion (GSIS) remain unknown. Herein, we report that CARD9 is expressed in human islets, rat islets, mouse islets and clonal INS-1 832/13 cells. Subcellularly, CARD9 is predominantly cytosolic (~75%) in INS-1 832/13 cells. siRNA-mediated depletion of CARD9 expression significantly (~50%) suppressed GSIS in INS-1 832/13 cells. Interestingly, glucose-induced activation of Rac1, a small G-protein, which is a requisite for GSIS to occur, is unaffected in CARD9-si transfected cells, suggesting that CARD9-mediates GSIS in a Rac1-independent fashion. Furthermore, insulin secretion promoted by KCl or mastoparan (a global G protein activator), remained resistant to CARD9 depletion in INS-1 832/13 cells. In addition, pharmacological inhibition (BRD5529) of interaction between CARD9 and TRIM62, its ubiquitin ligase, exerted no significant effects on GSIS. Lastly, depletion of CARD9 prevented glucose-induced p38, not ERK1/2 phosphorylation in beta cells. Based on these observations, we propose that CARD9 might regulate GSIS via a Rac1-independent and p38-dependent signaling module.
Targeting CARD9 with Small-Molecule Therapeutics Inhibits Innate Immune Signaling and Inflammatory Response to Pneumocystis carinii β-Glucans
Antimicrob Agents Chemother 2020 Oct 20;64(11):e01210-20.PMID:32839216DOI:10.1128/AAC.01210-20.
Pneumocystis jirovecii, the opportunistic fungus that causes Pneumocystis pneumonia (PCP) in humans, is a significant contributor to morbidity and mortality in immunocompromised patients. Given the profound deleterious inflammatory effects of the major β-glucan cell wall carbohydrate constituents of Pneumocystis through Dectin-1 engagement and downstream caspase recruitment domain-containing protein 9 (CARD9) immune activation, we sought to determine whether the pharmacodynamic activity of the known CARD9 inhibitor BRD5529 might have a therapeutic effect on macrophage innate immune signaling and subsequent downstream anti-inflammatory activity. The small-molecule inhibitor BRD5529 was able to significantly reduce both phospho-p38 and phospho-pERK1 signaling and tumor necrosis factor alpha (TNF-α) release during stimulation of macrophages with Pneumocystis cell wall β-glucans.
