生物活性:
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).

体内研究:
NN-390 (male CD-1 mice, 20 mg/kg, IP, single dose) increases plasma stability.NN-390 can improve PAMPA (parallel artificial membrane permeability assay)-BBB (blood-brain barrier) score.Pharmacokinetic Parameters of NN-390 in male male CD-1 mice.CompoundKT-531 5a; NN-390

体外研究:
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).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.NN-390 (0-2 μM, 1 h) markedly increases acetylation of α-tubulin and minimally changes acetylated histone H3.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).NN-390 (0-2 μM, 24 h) promotes cancer cells apoptosis in MV4-11 cells.
