Biological Activity
| Enzyme Assay | Auto-acetylation reactions of full-length p300 were performed in lysine acetyltransferase assay buffer at 30°C for 10 min with or without TTK21, followed by the addition of 1 μl of 4.7 Ci/mmol [3H]acetyl-CoA (NEN–PerkinElmer). The reaction mixture was further incubated for another 10 min at 30°C. The 3H-labeled acetylated p300 was visualized by fluorography followed by autoradiography.[1] |
| Cell Assay |
One equivalent of SOCl2 diluted in DCM was added dropwise to a suspension of 100 mg of CSP in DCM, followed by the addition of few drops of DMF . The reaction mixture was stirred at room temperature for 8–9 h. TTK21 dissolved in DCM was added dropwise to this solution. The reaction mixture was stirred for 8–9 h at room temperature. The solvent was then evaporated and washed with cold water. The crude product was centrifuged and the supernatant (i.e., water) was removed; this procedure was repeated 7–8 times. Washing was then performed using DCM and the supernatant was subsequently tested for absence of TTK21. The CSP-TTK21 conjugated was then dried at 60°C for 2–3 d.[1] Highly purified HeLa core histones were incubated in HAT assay buffer at 30°C for 10 min with or without baculovirus-expressed recombinant p300 or CBP in the presence or absence of TTK21, followed by addition of 1 μl of 3.6 Ci/mmol [3H]acetyl-CoA (NEN–PerkinElmer) and incubated for 10 min in a final volume of 30 μl at 30°C.[1] |

Solubility Data
| Solubility (In Vitro) | DMSO : ~100 mg/mL (~279.52 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (6.99 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
