Cort108297

Research use only, not for human use.

Cort108297 is a selective glucocorticoid receptor modulator and a selective GR antagonist with no affinity for other steroid receptors. Cort108297 showed a high affinity for GRs (Ki: 0.45nM).

Cort108297 is a specific glucocorticoid receptor (GR) antagonist. Cort108297 has a high affinity for GRs with a Ki of 0.45 nM.

In LAPC4 cells, co-treatment with Dexamethasone induces steady-state SGK1 expression 1.7-fold compared to R1881/Enzalutamide (RE) treatment alone. Addition of CORT118335 (1μM) inhibits Dexamethasone-induced SGK1 expression 50% while Cort108297 completely blocks the Dexamethasone-mediated SGK1 increase (p<0.05). KLK3 expression is increased 2.5-fold by Dexamethasone compared to treatment with RE. Both Cort108297 and CORT118335 antagonize Dexamethasone-induced KLK3 expression (by 48% and 60%, respectively, p<0.05). Following 3 days of Dexamethasone±SGRMs in CWR-22Rv1 cells, SGK1 gene expression is dramatically induced by ~100-fold compared to RE-treated cells and this induction is completely abrogated by both Cort108297 and CORT118335 (p<0.01). KLK3 is also induced (7.5-fold) by Dexamethasone compared to RE in CWR-22Rv1 cells; Cort108297 and CORT118335 inhibits this induction by 70% and 75%, respectively (p<0.01).

Ten-week-old, male, C57BL/6J mice are fed a diet containing 60% fat calories and water supplemented with 11% sucrose for 4 weeks. Groups (n=8) receive one of the following: Cort108297 (80?mg/kg QD), Cort108297 (40?mg/kg BID), Mifepristone (30?mg/kg BID), Rosiglitazone (10?mg/kg QD), or vehicle. Compared to mice receiving a high-fat, high-sugar diet plus vehicle, mice receiving a high-fat, high-sugar diet plus either Mifepristone or Cort108297 gain significantly less weight. At the end of the four week treatment period, mice receiving Cort108297 40?mg/kg BID or Cort108297 80?mg/kg QD also have significantly lower steady plasma glucose than mice receiving vehicle. Male rats are treated for five days with Mifepristone (10 mg/kg), Cort108297 (30 mg/kg and 60 mg/kg), Imipramine (10mg/kg) or vehicle and exposed to forced swim test (FST) or restraint stress. Both doses of Cort108297 potently suppress peak corticosterone responses to FST and restraint stress. However, only the higher dose of Cort108297 (60mg/kg) significantly decreases immobility in the forced swim test (FST) .
