体外研究
(In Vitro) | NN-390 exhibits cellular potency withIC50values 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 anIC50of 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].
Immunofluorescence | Cell Line: | HeLa cells[1] | | Concentration: | 0, 0.1, 0.25, 1, 2 μM | | Incubation Time: | 1 h | | Result: | Markedly increased acetylation of α-tubulin and minimally changed acetylated histone H3. |
Western Blot Analysis | Cell Line: | AML (MV4-11) cells[1] | | Concentration: | 0, 0.1, 0.5, 1, 5 μM | | Incubation Time: | 6 h | | Result: | Resulted in acetylation of α-tubulin from concentrations as low as 0.1 μM and with limited acetylation of histone H3 at only the highest concentration of 5 μM. |
Western Blot Analysis | Cell Line: | Group 3 MB (HD-MB03) cells[1] | | Concentration: | 0, 0.053, 0.106, 0.158, 0.211 μM | | Incubation Time: | 6 h | | Result: | Dose-dependent increased in acetylation of α-tubulin from the lowest concentration of 53 nM, with no observable change in acetylation of off-target histone H3 up to 211 nM. |
Apoptosis Analysis | Cell Line: | MV4-11 cells[1] | | Concentration: | 0, 0.25, 0.75, 1, 2 μM | | Incubation Time: | 24 h | | Result: | Promoted cancer cells apoptosis, 39% of cancer cells were undergoing late-stage apoptosis after 18 h at 2 μM, and 11% of cells were in the late apoptosis stage at 0.25 μM. |
