Use | PCI 29732 is an effective reversible BTK inhibitor with Kiapp values of 8.2, 4.6 and 2.5 nM for BTK, Lck and Lyn respectively. PCI 29732 has only moderate inhibitory activity on Itk, another Tec family kinase. PCI 29732 inhibit the function of ABCG2 by competitively binding the ATP binding site of ABCG2. |
In vitro study | PCI29732 shows cytotoxicity in different cells. The IC 50 values are 7.94 μM for S1, 7.79 μM for S1-MI-80, 6.55 μM for H460, 6.34 μM for H460/MX20, 6.14 μM for KB, 6.02 μM for KBv200, 12.45 μM for HEK293/pcDNA3, 14.58 μM for HEK293-ABCG2-482-R2, and 13.24 μM for HEK293-ABCG2-482-T7 cells. PCI-29732 blocks the transcriptional up-regulation of a panel of B-cell activation genes in human CD20+ B cells stimulated at the B-cell antigen receptor (BCR). |
In vivo study | PCI 29732 inhibits the function of ABCG2 by competitively binding to the ATP-binding site of ABCG2 and enhances the anti-tumor efficacy of substrate chemotherapeutic agents. PCI 29732 (20 mg/kg; p.o.; every 3 d × 5 times) enhances the anticancer efficacy of Topotecan in the H460/MX20 cell xenograft nude mice model. Animal Model: 5-6 weeks old athymic nude mice (bearing H460/MX20 cells) Dosage: 20 mg/kg (combination with Topotecan; every 3 d × 5 times, i.p., 3 mg/kg; topotecan was given 1 h after PCI29732 administration) Administration: P.o.; every 3 d × 5 times Result: Significant reductions in tumor weight and volume were observed in the group treated with PCI29732 in combination with Topotecan. |
