MTOB sodium is a potent C-terminal binding protein (CtBP) inhibitor. MTOB sodium attenuates repetitive head injury-elicited neurologic dysfunction and neuroinflammation via inhibition of the transactivation activity of CtBP1 and CtBP2. MTOB sodium antagonizes the transcriptional regulatory activity of CtBP1 and CtBP2 by eviction from their target promoters in breast cancer cell lines.

Description

MTOB sodium is a potent C-terminal binding protein (CtBP) inhibitor. MTOB sodium attenuates repetitive head injury-elicited neurologic dysfunction and neuroinflammation via inhibition of the transactivation activity of CtBP1 and CtBP2. MTOB sodium antagonizes the transcriptional regulatory activity of CtBP1 and CtBP2 by eviction from their target promoters in breast cancer cell lines[1][2].

IC50 & Target

CtBP[1]
In Vitro

MTOB sodium (10 mM) causes significant derepression (P<0.05) of 40% of CtBP target genes (including FGF9, CTNNB1, CEBPB, et al.) in MCF-7 and 46% in MBA-MD-231; increases the pro-epithelial E-cadherin/Vimentin ratio while reducing the pro-mesenchymal CD44/CD24 ratio, with a more significant trend (P<0.05) in MCF-7[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
