A-366 (A366) is a novel, potent and peptide-competitive inhibitor of the histone methyltransferase G9a with anticancer activity. It inhibits G9a with an IC50 3 nM and > 100-fold selectivity over other methyltransferases and other non-epigenetic targets. A-366 has been shown to inhibit H3K9 methylation in cells with an IC50 of 100 nM and exhibits minimal cellular toxicity compared with previous quinazoline-based probes. A-366 selectively inhibits G9a and the closely related GLP (EHMT1), but not other histone methyltransferases. A-366 has significantly less cytotoxic effects on the growth of tumor cell lines compared to other known G9a/GLP small molecule inhibitors despite equivalent cellular activity on methylation of H3K9me2.
| ln Vitro |
A-366 (0.01-10 μM; 14 days) impacts the viability of MV4;11 cells and causes differentiation [4]. In PC-3 prostate cancer cells, A-366 (0.3-3 μM; 72 hours) decreases overall H3K9me2 levels in a concentration- and time-dependent manner, with a cellular EC50 of roughly 300 nM. A-366 (0.01-10 μM; 4 days; HL-60 cells) decreased differentiation and concomitant proliferation in a dose-dependent manner. A-366-treated HL-60 cells' DNA content analysis revealed an increase of G1 phase cells, which is consistent with cell arrest [4].

| ln Vivo |
Growth suppression occurs when MV4;11 xenografts are treated with A-366 (30 mg/kg; osmotic minipump; once daily for 14 days) [4].

Cell Viability Assay [4]
Cell Types: MV4; 11 cells Tested Concentrations: 0.01-10 μM Incubation Duration: 14 days Experimental Results: Resulted in inhibition of proliferation and diminished viability, corresponding to the dose response observed by CD11b staining. |
| Animal Protocol |
Animal/Disease Models: 6-8 weeks old SCID beige female mice (MV4; 11 xenografts) [4]
Doses: 30 mg/kg Route of Administration: via mini-osmotic pump; one time/day for 14 days Experimental Results: In In the model, A-366 treatment produced a modest 45% tumor growth inhibition. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (7.59 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 25.0 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: ≥ 2.5 mg/mL (7.59 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in 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 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. (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.
