Trichostatin A

カタログ番号 T6270   CAS 58880-19-6
別名: TSA

Trichostatin A (TSA) is a natural derivative of diene isohydroxamic acids. Trichostatin A is a histone deacetylase inhibitor (IC50=1.8 nM) that is reversible and specific. Trichostatin A leads to the hyperacetylation of core histones, which regulates chromatin structure.

説明 Trichostatin A (TSA) is a natural derivative of diene isohydroxamic acids. Trichostatin A is a histone deacetylase inhibitor (IC50=1.8 nM) that is reversible and specific. Trichostatin A leads to the hyperacetylation of core histones, which regulates chromatin structure.
ターゲット&IC50 HDAC:1.8 nM
In vitro METHODS: Eight breast cancer cells MCF-7, T-47D, ZR-75-1, BT-474, MDA-MB-231, MDA-MB-453, CAL 51 and SK-BR-3 were treated with Trichostatin A (10-12 -10-5 M) for 96 h. The viability of the cells was determined by SRB. Cell viability was determined by SRB
RESULTS: Trichostatin A inhibited the proliferation of eight breast cancer cell lines with a mean IC50=124.4±120.4 nM (range 26.4-308.1 nM). [1]
METHODS: Esophageal squamous cell carcinoma cells EC9706 and EC1 were treated with Trichostatin A (0.3-1 μM) for 48 h. Apoptosis was detected using Flow Cytometry.
RESULTS: There was no significant increase in the percentage of early apoptosis at 0.3 and 0.5 μM Trichostatin A doses. However, 1.0 μM Trichostatin A treatment significantly induced early apoptosis compared with control. In addition, the percentage of mid- and late-stage apoptosis increased in a concentration-dependent manner. [2]
METHODS: Esophageal squamous cell carcinoma cells EC9706 and EC1 were treated with Trichostatin A (0.3-1 μM) for 60 min, and the expression levels of target proteins were detected using Western Blot.
RESULTS: Trichostatin A decreased the protein levels of PI3K as well as p-Akt and p-ERK1/2 in a dose-dependent manner. acetylation of histone H4 was increased in a concentration-dependent manner. [2]
In vivo METHODS: To assay antitumor activity in vivo, Trichostatin A (500 μg/kg) was injected subcutaneously into rats with NMU-induced mammary carcinoma tumors once daily for four weeks.
RESULTS: Trichostatin A showed significant antitumor activity in vivo. tumors in Trichostatin A-treated rats had benign phenotypes, fibroadenomas or tubular adenomas, suggesting that the antitumor activity of Trichostatin A may be attributable to induction of differentiation. [1]
METHODS: To assay antitumor activity in vivo, Trichostatin A (0.5-1 mg/kg twice weekly) and Quercetin (10 mg/kg three times weekly) were injected intraperitoneally into nude mice bearing human lung adenocarcinoma tumor A549 for thirteen weeks.
RESULTS: High-dose Trichostatin A significantly inhibited tumor growth, while low-dose Trichostatin A and Quercetin alone had no effect. However, the combination of low-dose Trichostatin A and Quercetin significantly inhibited tumor growth. [3]
キナーゼ試験 In vitro HDAC activity: Total cellular extracts are prepared from each breast cancer cell line (MCF-7, T-47D, ZR-75-1, BT-474, MDA-MB-231, MDA-MB-453, CAL 51, or SK-BR-3). A 20 μL crude cell extract (~2.5 ×105 cells), in the presence of varying concentrations of Trichostatin A in 0.1% (v/v) ethanol or 0.1% (v/v) ethanol as vehicle control, are incubated for 60 minutes at 25 °C with 1 μL (~1.5 × 106 cpm) of [3H]acetyl-labeled histone H4 peptide substrate (NH2-terminal residues 2-20) that has been acetylated with [3H]acetic acid, sodium salt (3.7 GBq/mmol) by an in vitro incorporation method. Each 200 μL reaction is quenched with 50 μL of 1 M HCl/0.16 M acetic acid and extracted with 600 μL of ethyl acetate, and released [3H]acetate is quantified by scintillation counting. IC50 values are determined graphically using nonlinear regression to fit inhibition data to the appropriate dose-response curve.
細胞研究 Cells are exposed to various concentrations of Trichostatin A for 96 hours. After treatment, cell proliferation is estimated using the sulforhodamine B colorimetric assay. Cell viability is determined by trypan blue exclusion. (Only for Reference)
