体内（毎回新しく調製した物を用意してください）

Homogeneous suspension	CMC-NA	≥5mg/ml	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution	5%DMSO 1 40%PEG300 2 55%ddH2O この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。	5.000mg/ml (18.57mM)	Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 400 μL of PEG 300, mix evenly to clarify it; then continue to add 550 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明	Tacedinaline (CI994, PD-123654, GOE-5549, Acetyldinaline) is a selective class I HDAC inhibitor with IC50 of 0.9, 0.9, 1.2, and >20 μM for human HDAC 1, 2, 3, and 8, respectively. Phase 3.
in vitro	CI-994 (< 160 mM) shows cytostatic effect with concomitant increase at G0/G1 phase, a reduction at S phase level and increased apoptosis in A-549 and LX-1 cells. ^[2] CI-994 inhibits growth of LNCaP cell with IC50 of 7.4 μM. ^[3] CI-994 exerts activity against several tumor cell lines with greater cytotoxicity against the solid tumors relative to both the leukemia and normal fibroblast cell lines. ^[4] CI-994 inhibits growth of rat leukemia BCLO cells with IC50 of 2.5 μM. ^[5]
in vivo	CI-994 exerts demonstrated antitumor activity against several tumor models, including the chemo-resistant mouse pancreatic ductal carcinoma as well as the human prostate tumor model LNCaP. ^[4]

	実験の流れ	LNCaP cell lines are maintained in RPMI 1640 medium containing 10% fetal bovine serum, 1% penicillin and streptomycin, as the complete culture medium. Cells (2×10⁴) are seeded in 24-well plates and incubated in a 5% CO₂ incubator at 37 °C for 1 day. Cultures are treated with CI-994, alone and in combination on day 2 and 4. Cells are washed on day 2 and 4 and media are changed. Mitochondrial metabolism is measured as a marker for cell growth by adding 100 μL/well MTT (5 mg/mL in medium) with 2 hours incubation at 37 °C on Day 6. Crystals formed are dissolved in 500 μL of DMSO. The absorbance is determined using a microplate reader at 560 nm. The absorbance data are converted into cell proliferation percentage. Each assay is performed in triplicate.
