ITRI-90
ITRI-90 is an orally active androgen receptor (AR) PROTAC degrader. ITRI-90 effectively degrades both full-length AR (AR-FL) and the splice variant AR-V7 protein via the ubiquitin-proteasome system, thereby inhibiting AR transcriptional activity and the target gene expression. ITRI-90 significantly inhibits the proliferation of prostate cancer cells and induces apoptosis, include Enzalutamide-resistant growth cell. ITRI-90 exhibits favorable pharmacokinetic properties and demonstrates potent antitumor efficacy in vivo. ITRI-90 can be used for prostate cancer research.

Biologische Aktivität
ITRI-90 (0-20 μM,24 h) reduces AR-FL and AR-V(ΔLBD) proteins in LNCaP, CWR22Rv1, VCaP cells (with DC50 = 2.12, 5.73 and 8.67 nM for AR-FL proteins and DC50 = 4.72 and 0.29 nM for AR-V proteins in CWR22Rv1, VCaP cells respectively) [1].
ITRI-90 (10 μM, 24 h) demonstrates a prolonged duration of effect, enabling less frequent dosing in LNCaP, CWR22Rv1 and VCaP cells[1].
ITRI-90 (10 μM, 6 or 10 h) degrades AR protein levels via ubiquitin-proteasome dependent system in CWR22Rv1 and ITRI-126, cells[1].
ITRI-90 (0.1-1 μM,24 h) less efficiently inhibits AR target expression on both AR and AR-V7 signaling and exerts AR inhibition mediated via NTD-targeted protein degradation or direct blockade of ligand binding in LNCaP and CWR22Rv1 cells[1].
ITRI-90 (0.001-100 μM, 24 h or 7 days) specifically and effectively inhibits cancer cell proliferation and induces apoptosis in LNCaP, CWR22Rv1 and VCaP cells[1].
ITRI-90 (5 or 10 μM, one day ) effectively degrades Enzalutamide (HY-70002)-induced AR-FL and truncated AR V(ΔLBD) proteins in both short-term treated and long term acquired resistant cells, thereby significantly impairing the enzalutamide-resistant cell growth in VCaP, C4-2B and C4-2B/EnzR cells[1].
ITRI-90 shows low plasma clearance rate (6.62 mL/min/kg) and achieves well actual body exposure (AUC/Dose = 2502.4) in mouse liver microsomes[1].
