AMI-1
Based on 7 publication(s) in Google Scholar
AMI-1 is a potent, cell-permeable and reversible inhibitor of protein arginine N-methyltransferases (PRMTs), with IC50s of 8.8 μM and 3.0 μM for human PRMT1 and yeast-Hmt1p, respectively. AMI-1 exerts PRMTs inhibitory effects by blocking peptide-substrate binding.

AMI-1 can inhibit the in vitro methylation reactions performed by all five recombinantly active PRMTs (PRMT1, -3, -4, and -6 and Hmt1p)[2].
AMI-1 not only inhibits type I PRMTs (PRMT1, 3, 4 and 6) but also type II PRMT5[2].
AMI-1 specifically inhibits arginine, but not lysine, methyltransferase activity in vitro and does not compete for the AdoMet binding site[3].
AMI-1 inhibits methylation of GFP-Npl3 and cellular proteins[3].
AMI-1 (0.6-2.4 mM; 48-96 hours) inhibits the cell viability of sarcoma in S180 and U2OS cells in a time-dependent and dose-dependent manner in vitro[4].
AMI-1 (1.2-2.4 mM; 48-72 hours) reduces S180 cell viability through the induction of cell apoptosis[4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

AMI-1 (0.5 mg; intratumorally; daily; for 7 days) downregulates PRMT5 but does not regulate the expression of PRMT7 in a tumor xenograft model[4].
AMI-1 (0.5 mg; intratumorally; daily; for 7 days) decreases the levels of H4R3me2s and H3R8me2s in a tumor xenograft model[4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (4.56 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (4.56 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
