Product Description:
CX-5461 is an inhibitor of rRNA synthesis, selectively inhibits Pol I-driven transcription of rRNA with IC50 of 142 nM in HCT-116, A375, and MIA PaCa-2 cells, has no effect on Pol II, and possesses
250- to 300-fold selectivity for inhibition of rRNA transcription versus DNA replication and protein translation.
In vitro :
CX-5461 is found to selectively inhibit rRNA synthesis (Pol I IC50=142 nM; Pol II IC50 > 25 μM; selectivity ~200-fold) in the HCT-116 cells. Selective inhibition of rRNA synthesis by CX-5461 is
confirmed in two other human solid tumor cell lines; melanoma A375 (Pol I IC50 = 113 nM; Pol II IC50 > 25 μM) and pancreatic carcinoma MIA PaCa-2 (Pol I IC50=54 nM; Pol II IC50 ~25 mM). CX-5461
possesses 250- to 300-fold selectivity for inhibition of rRNA transcription versus DNA replication and protein translation. CX-5461 exhibits broad antiproliferative potency in a panel of cancer
cell lines in human cancer cell lines, but has minimal effect on viability of nontransformed human cells. The median EC50 across all tested cell lines is 147 nM, yet all normal cell lines have EC50
values of approximately 5, 000 nM. Evaluation of the antiproliferative dose response for HCT-116, A375, and MIA PaCa-2 cell lines yield EC50 values of 167, 58, and 74 nM. CX-5461 induces autophagy
and senescence in solid tumor cancer cells, rather than apoptosis, through a p53-independent process.
