CAY10603
CAY10603 is a potent and selective inhibitor of HDAC6 (IC50 = 2 pM, as compared with 271, 252, 0.42, 6851, and 90.7 nM for HDAC1, 2, 3, 8, and 10, respectively)[1].?
CAY10603 inhibits the proliferation and induces apoptosis of lung adenocarcinoma cells. In addition, CAY10603 works in concert with gefitinib to induce apoptosis in lung adenocarcinoma cell lines, in part due to EGFR instability and EGFR pathway inactivation[2].?
In C57BL/6 mice model of endotoxemia, CAY10603 (intraperitoneal injection, 5 mg/kg, 2h) pretreatment significantly inhibits endotoxin-induced caspase-3 activation and reduces endotoxin-induced pulmonary edema form[3].?

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. |

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. |
