MG-149 (MG149) is a novel, potent and selective histone acetyltransferase (HAT) inhibitor with anticancer activity. It inhibits HAT with IC50 of 74 μM and 47 μM for Tip60 and MOF, respectively. It shows little potent for PCAF and p300(IC50 >200 uM). Docking study (molecular modeling) shows that the inhibition of Tip60 by MG 149 is competitive with respect to Ac-CoA in the Ac-CoA binding pocket of Tip60. MG 149 also inhibits the activity of HAT in nuclear extracts from HeLa cells using biotinylated histone H3 or histone H4 peptides as substrates. It is found to be more potent for histone H3 compared to histone H4.
ln Vitro |
MG 149 (Tip60 HAT inhibitor) inhibits roughly 90% of Tip60 activity at 200 μM, but has no inhibitory effect on p300 and PCAF. MG 149 essentially competes with Ac-CoA but not with histone substrates. HAT inhibition experiments with MG 149 indicated that both drugs strongly suppressed HAT activity in nuclear extracts from different locations (p < 0.05) [1].

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.75 mg/mL (8.08 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (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 27.5 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.75 mg/mL (8.08 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 27.5 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.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
