生物活性

Proteasome inhibitor IX (PS-IX; AM114) is a Chalcone derivative and a chymotrypsin-like activity of the 20S proteasome inhibitor with an IC50 value of ~1 μM. Proteasome inhibitor IX exhibits HCT116 p53+/+ cells growth inhibitory activity with an IC50 value of 1.49 μM. Proteasome inhibitor IX has potent anticancer activity[1][2].

IC50 & Target

IC50: 1 μM (20S proteasome)[1]

体外研究
(In Vitro)

Proteasome inhibitor IX (AM114; 0.1-10 µM; 14 days; HCT116 p53+/+ cells) treatment causes a loss of cell survival in the p53+/+ and p53-/- cells by approximately 70 and 20%, respectively at a concentration of 1 µM[1].
Proteasome inhibitor IX (AM114) exhibits potent activity against p53+/+ cells in colony formation assay, with an IC50 value of 0.6 µM[1].
Incubation of HCT116 p53+/+ cells with 1 µM Proteasome inhibitor IX (AM114) causes 28% of the cells to exhibit positive Annexin V staining at 48 h, and this fraction of dead cells increased to 76% at 72 h[1].
Proteasome inhibitor IX (AM114) treatment inhibits the chymotrypsin-like activity of the 20S proteasome in vitro, leading to a significant accumulation of ubiquitinated p53 and other cellular proteins in whole cells[1].
