Biological Activity
| ln Vitro | By blocking OPA1, MYLS22 inhibits vascular tumorization and associated vascular angiogenesis, hence reducing tumor development and metastasis and successfully returning vascular tumor morphology to normal [2]. Acute myeloid leukocyte (AML) cell clonal development is inhibited by MYLS22 (10-30 μM; 7-10 days) with an IC50 of 12.5 μM [1]. In AML cells, MYLS22 (10-30 μM; 7-10 days) can effectively prevent mitochondrial fusion, lowering ROS levels and blocking the cell cycle during the G0/G1 transition phase [1]. |
| ln Vivo | MYLS22 (30 mg/kg; intraperitoneal injection; once daily for 7 days) significantly reduced the total tumor burden in mice [1]. MYLS22 (10 mg/kg; i.p.; once daily for six days) suppresses tumor growth in subcutaneous B16F10 melanoma mice by targeting OPA1 [3]. |

Solubility Data
| Solubility (In Vitro) | DMSO : ~25 mg/mL (~56.37 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 1.25 mg/mL (2.82 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 12.5 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: ≥ 1.25 mg/mL (2.82 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 12.5 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.) |
