ARD-2128 是一种高效的 PROTAC 雄激素受体 (AR) 降解剂。ARD-2128 可有效降低 AR 蛋白并抑制肿瘤组织中 AR 调节的基因，在没有毒性迹象的情况下抑制肿瘤生长。ARD-2128 作用在前列腺癌的研究上。
ARD-2128 is a highly potent, orally bioavailable PROTAC androgen receptor (AR) degrader. ARD-2128 effectively reduces AR protein, suppresses AR-regulated genes in tumor tissues, and inhibits growth of tumor without signs of toxicity. ARD-2128 has the potential for the research of the prostate cancer[1].
ARD-2128 is highly potent and effective in the inhibition of cell growth in the VCaP cell line and LNCaP cell line with the IC50 values of 4 nM and 5 nM, respectively[1].ARD-2128 (1, 10, 100, and 1000 nM; 24 hours) effectively reduces the AR protein level by >50% at 1 nM and achieves the AR degradation of >90% at 10, 100, and 1000 nM, respectively, in VCaP cell[1].
ARD-2128 (20 mg/kg; p.o.; once) is effective in reducing the level of AR protein in mice after 24 hours[1].ARD-2128 (10-40 mg/kg; p.o.; daily for 21 days) shows antitumor activity in the VCaP xenograft model in mice[1].ARD-2128 (5mg/kg; p.o.) treatment shows the Cmax, AUC0-t and t1/2 values of 1304 ng/mL, 22361 ng h/mL and 18.8 hours, respectively[1].
