BML-210 (also known as BML210; CAY-10433) is novel and potent HDAC inhibitor (IC50 value: 5 μM) with anticancer activity. BML-210 induces growth inhibition and apoptosis and regulates HDAC and DAPC complex expression levels in cervical cancer cells. BML-210 can inhibit cell growth and induce apoptosis in cervical cancer cells, what correlates with down-regulation of HDAC class I and II and changes in the DAPC expression levels. Cell cycle analysis indicated that HeLa cell treatment with 20 and 30 μM concentration of BML-210 increased the proportion of cells in G0/G1 phase, and caused accumulation in subG1, indicating that the cells are undergoing apoptosis.

Biological Activity
| Targets | HDAC4; HDAC4-VP16-driven reporter |
| ln Vitro | NB4 cells are inhibited in their growth and proliferation by BML-210 (10, 20 μM; 24, 48 hours) [2]. The amount of S phase NB4 cells was reduced by BML-210 (10, 20 μM; 24, 48 hours), and at 20 μM, G0 BML-210 (10, 20 μM; 24, 48 hours) had a cytotoxic effect on NB4 cells. A dose of 10 μM is sufficient for BML-210 to cause cell death [2]. In NBT4 cells, BML-210 (10, 20 μM; 24, 48 hours) suppresses HDAC expression and activity [2]. HDAC4-VP16 expression is not downregulated by BML-210[1].Cell lines. NB4 cells Concentration: 10, 20 μM Incubation period: 24, 48 hours Outcomes: Reduced NB4 cell growth and proliferation in a time- and dose-dependent manner. |
| ln Vivo |
BML-210 (20 mg/kg; intraperitoneal injection; three times weekly for two weeks) markedly reduced the amount of body weight and tumor growth. In immunodeficient nude mice, BML-210 has no influence on tumor growth or body weight (Nu/J).
In this study, researchers show that the epigenetic inhibitors GSK-LSD1, CUDC-101 and BML-210, identified by the screen, display antitumour activities in orthotopic mammary tumours in mice, that they upregulate antigen presentation mediated by the major histocompatibility complex class I on breast tumour cells and that treatment with BML-210 substantially sensitized breast tumours to the inhibitor of the checkpoint programmed death-1. Standardized measurements of tumour-cell killing activity facilitated by tumour-organoid-T-cell screens may help with the identification of candidate immunotherapeutics for a range of cancers[3]. |
| Enzyme Assay |
HDAC Activity Analysis[2] Proteins were isolated using ProteoJET™ Mammalian Cell Lysis Reagent (Fermentas, Vilnius, Lithuania) according to the manufacturer's instructions. HDAC activity analysis was determined using EpiQuik™ HDAC Activity/Inhibition Assay Kit according to the manufacturer’s instructions. Absorbance was measured using Tecan-Control, Infinite 200 microplate reader at 450 nm. Activity (ng/h/mL) was calculated using formula.[2] Drug treatment and luciferase assay[1] For the two-hybrid assay, cells were treated with 10 µM drug overnight unless indicated otherwise. The amount of DMSO was kept below 0.2% V/V. A luciferase assay was performed according to the manufacturer’s protocol. The luciferase response was normalized against the Renilla Luciferase as an internal control. The data are presented as a mean ± SD (n = 2) of normalized HDAC4:MEF2 luciferase response against the normalized response values for GAL4-VP16 for each condition to correct for non-specific inhibition of the luciferase signal. |
