Taking the 1 mL working solution as an example, add 50 μL of 80 mg/ml clarified DMSO stock solution to 450 μL of PEG 300, mix evenly to clarify it; then continue to add 500 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	THZ1 is a covalent CDK7 inhibitor which has the unprecedented ability to target a remote cysteine residue located outside of the canonical kinase domain, providing an unanticipated means of achieving selectivity for CDK7.
in vitro	THZ1 uses a unique mechanism, combining ATP-site and allosteric covalent binding, as a means of attaining potency and selectivity for CDK7. THZ1 irreversibly inhibits RNAPII CTD phosphorylation by covalently targeting a unique cysteine located outside the kinase domain of CDK7. THZ1, but not THZ1-R, completely inhibits the phosphorylation of the established intracellular CDK7 substrate RNAPII CTD at Ser 5 and Ser 7, with concurrent loss of Ser 2 phosphorylation at 250 nM in Jurkat cells. THZ1 exhibits strong antiproliferative effects across a broad range of cancer cell lines from various cancer types. In Jurkat cells, low-dose THZ1 has a profound effect on a small subset of genes, including the key regulator RUNX1, thus contributing to subsequent loss of the greater gene expression program and cell death^[1]. THZ1 causes defects in Pol II(polymerase II) phosphorylation, co-transcriptional capping, promoter proximal pausing, and productive elongation^[2].
in vivo	THZ1 reduces the proliferation of KOPTK1 T-ALL cells in a human xenograft mouse model. THZ1 is well tolerated at 10 mg/kg with no observable body weight loss or behavioural changes, suggesting that it causes no overt toxicity in the animals^[1].

	実験の流れ	Cells are treated with THZ1, THZ1-R or dimethylsulphoxide (DMSO) for 0-6 h to assess the effect of time on the THZ1-mediated inhibition of RNAPII CTD phosphorylation. For subsequent experiments cells are treated with compounds for 4 h as determined by the time-course experiment described earlier, unless otherwise noted. For inhibitor washout experiments, cells are treated with THZ1, THZ1-R or DMSO for 4 h. Medium containing inhibitors is subsequently removed to effectively 'washout' the compound and the cells are allowed to grow in the absence of inhibitor. For each experiment, lysates are probed for RNAPII CTD phosphorylation and other specified proteins.
