| 產(chǎn)品描述： | CX-5461 is a potent and oral rRNA synthesis inhibitor. It inhibits RNA polymerase I-driven transcription of rRNA with IC50s of 142, 113, and 54 nM in HCT-116, A375, and MIA PaCa-2 cells, respectively |
| 靶點： |
IC50: 54 nM (rRNA synthesis, MIA PaCa-2 cells), 113 nM (rRNA synthesis, A375 cells), 142 nM (rRNA synthesis, HCT-116 cells);DNA/RNASynthesis |
| 體內(nèi)研究： |
CX-5461 displays antitumor activity against human solid tumors in murine xenograft models. CX-5461 (50 mg/kg, p.o.) shows significant MIA PaCa-2 growth inhibition with TGI equal to 69% on day 31 and 79% TGI on A375 on day 32. CX-5461 (50 mg/kg, p.o.) inhibits the Eμ-Myc tumor cells with 84% repression in Pol I transcription at 1 hr posttreatment in C57BL/6 mice. CX-5461 also induces a rapid reduction in tumor burden in the lymph nodes and a concomitant reduction of spleen size to within the normal range |
