Sigma Aldrich Fine Chemicals Biosciences CREB Inhibitor 666-15 - Ca

Catalog No. 502901753
Encompass

A cell-permeable naphthol derivative that acts as a highly potent and selective inhibitor of cAMP response element-binding protein (CREB)-mediated gene transcription (IC50 81 nM by CREB RLuc reporter assay with transfected HEK 293T cells). Also shown to inhibit forskolin-stimulated transcription of Nurr1/NR4A2 (~ 50 nM). Diminishes CREB phosphorylation and reduces colony forming ability of wild-type AML cells. Inhibits the growth of cancer cells (GI50 46 73 310 and 470 nM for MDA-MB-468 MDA-MB-231 MCf-7 and A549 respectively) without affecting normal cells. Completely suppresses the growth of MDA-MB-468 xenografts in mice (~ 10 mg/kg i.p. 5 days/week for 5 weeks).Please note that the molecular weight for this compound is batch-specific due to variable water content. Please refer to the vial label or the certificate of analysis for the batch-specific molecular weight. The molecular weight provided represents the baseline molecular weight without water.
