CAY10603 (BML-281) is a potent and selective HDAC6 inhibitor, with an IC50 of 2 pM; CAY10603 (BML-281) also inhibits HDAC1, HDAC2, HDAC3, HDAC8, HDAC10, with IC50s of 271, 252, 0.42, 6851, 90.7 nM.
CAY10603 (Compound 7) shows potent inhibitory activities against pancreatic cancer cell lines, with IC50s of 1, 0.3, 0.1, 0.1, 0.6, <1, 0.5 μM for BxPC-3, HupT3, Mia Paca-2, Panc 04.03, SU.86.86, HMEC, HPDE6c7, respectively. CAY10603 (100 nM, 200-300 nM) is active against both the Mia Paca-2 and Panc04.03 cell lines[1]. CAY10603 inhibits HDAC6 deacetylase activity, and supresses the proliferation of lung adenocarcinoma cells. CAY10603 also induces apoptosis of lung adenocarcinoma cells. Furthermore, CAY10603 synergizes with gefitinib to induce apoptosis in lung adenocarcinoma cell lines, partly through the destabilization of EGFR and inactivation of the EGFR pathway[2].

Applications |
CAY10603 showed potent antiproliferative activity against pancreatic cancer cell lines with IC50 of <1 μM. CAY10603 was active against both the Mia Paca-2 and Panc04.03 cell lines at the 100 nM level and at the 200–300 nM level against HupT3. CAY10603 (0.1 μM, 6 h) blocked TNF-α-induced caspase-3 activation in endothelial cells. In HPAECs, pre-treated with CAY10603 (CAY, 0.1 μM) for 6 h inhibited TNF-α-induced endothelial permeability. CAY10603 (0.05 μM) significantly decreased the cell viability of NSCLC cells. In A549 and H460 cells, CAY10603 (0.01-0.16 μM) dose-dependently decreased total EGFR levels and the phosphorylation of EGFR, AKT, and ERK. In two human lung adeno-carcinoma cell lines: A549 and HCC827, CAY10603 treatment dose-dependently (0.02-0.32 μM) decreased cell proliferation. CAY10603 decreased clone numbers of the lung adenocarcinoma cell lines. CAY10603 clearly induced apoptosis in the lung adenocarcinoma cell line A549. Combination of CAY10603 (0.01 μM) and gefitinib (1 μM) for 48h remarkably inhibited the clono-genic survival of the A549 cells. |

Intraperitoneal injection, 5 mg/kg, 2 h |
|
Application |
In a C57BL/6 mouse model of endotoxemia, pre-treatment with CAY10603 significantly inhibited endotoxin-induced caspase-3 activation and attenuated endotoxin-induced lung edema formation in the lung tissues. |

Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
