INCB127443

INCB127443 is an orally active and selective CDK2/cyclin E1 inhibitor (IC₅₀ = 0.99 nM). INCB127443 is an ATP-competitive inhibitor that blocks Rb phosphorylation and cell cycle progression, and inhibits S-phase progression and proliferation in cyclin E-overexpressing ovarian cancer cells. INCB127443 shows antitumor efficacy and inhibits Rb phosphorylation in a cyclin E-overexpressing ovarian cancer xenograft model. INCB127443 can be used for research related to ovarian cancer.

In Vitro

Anti-cancerCell Cycle RegulationOthers

Anti-cancer

INCB127443 (14 days) exhibits a stronger inhibitory effect on the long-term proliferation of CCNE1-high COV318 and OVCAR-3 cells than on CCNE1-low COV504 cells^[1].

Anti-cancer

Cell Cycle Regulation

INCB127443 (1.5-10000 nM) potently induces S-phase inhibition in CCNE1-high COV318 and OVCAR-3 cells, whereas it shows lower potency in CCNE1-low COV504 cells^[1].

Cell Cycle Regulation

INCB127443 (compound 30) potently inhibits CDK2/cyclin E1 with an IC₅₀ of 0.99 nM and shows selectivity over CDK1 and other tested CDK/cyclin complexes; it potently binds CDK2/cyclin E1 in cells with an IC₅₀ of 5.9 nM^[1].
INCB127443 exhibits 20-25-fold cellular selectivity relative to CDK1, CDK4, and CDK6 in tested cells and whole blood models^[1].

Others

INCB127443 has a low intrinsic clearance in human microsomes, moderate Caco-2 permeability, an unbound plasma fraction of 8%, and high FaSSIF solubility^[1].

In Vivo

Anti-cancer

INCB127443 (compound 30) (3-100 mg/kg; p.o.; twice daily; 5 days) dose-dependently inhibits tumor pRb S780 in CCNE1-high OVCAR-3 xenografts^[1].
INCB127443 (3-100 mg/kg; p.o.; twice daily or once daily; 24 days) produces dose-dependent antitumor activity in CCNE1-high OVCAR-3 xenograft tumors, with a tumor growth inhibition rate of 83% at 100 mg/kg twice daily^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
