Description

NN-390 is a potent and selective HDAC6 inhibitor, with an IC50 of 9.8 nM. NN-390 penetrates the blood-brain barrier (BBB). NN-390 shows study potential in metastatic Group 3 MB (medulloblastoma)[1].

In Vitro

NN-390 exhibits cellular potency with IC50 values of 1.19 μM in MV4-11 cells and 1.38 μM in MM.1S cells while having minimal effects on noncancerous counterparts (IC50 > 50 μM in MRC-9)[1].
NN-390 (72 h) strongly decreases proliferation in HD-MB03 cells, with an IC50 of 0.13 μM, and significantly impairs self-renewal of BTIC-enriched HD-MB03s[1].
NN-390 (0-2 μM, 1 h) markedly increases acetylation of α-tubulin and minimally changes acetylated histone H3[1].
NN-390 (6 h) results in acetylation of α-tubulin from concentrations as low as 0.1 μM (0-0.2 μM), and dose-dependent increases in acetylation of α-tubulin (0-0.2 μM)[1].
NN-390 (0-2 μM, 24 h) promotes cancer cells apoptosis in MV4-11 cells[1].

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.
