| Toxicity/Toxicokinetics |
Hepatotoxicity
In controlled trials, serum aminotransferase elevations occurred in 2% to 6% patients treated with omacetaxine, but most elevations were mild and transient with only rare patients requiring dose modification or discontinuation for liver test abnormalities. Clinically apparent liver injury with jaundice was not reported in the preregistration trials of omacetaxine and is not mentioned in the product label. Since the approval and more wide scale use of omacetaxine, there have been no publications or descriptions of the hepatotoxicity with jaundice associated with its use. Thus, clinically apparent liver injury due to omacetaxine must be rare, if it occurs at all. Likelihood score: E (unlikely cause of clinically apparent liver injury). |

| Additional Infomation |
Cephalotaxine is a benzazepine alkaloid isolated from Cephalotaxus harringtonia. It is a benzazepine alkaloid, a benzazepine alkaloid fundamental parent, an organic heteropentacyclic compound, an enol ether, a cyclic acetal, a secondary alcohol and a tertiary amino compound.
Omacetaxine is a semisynthetic cephataxine that acts as a protein translation inhibitor and is used to treated chronic myeloid leukemia that is resistant to tyrosine kinase receptor antagonists. Omacetaxine is associated with a low rate of serum enzyme elevation during therapy, but has not been linked to cases of clinically apparent liver injury with jaundice. Cephalotaxine has been reported in Cephalotaxus fortunei, Cephalotaxus hainanensis, and other organisms with data available. Omacetaxine is a protein translation inhibitor and cytotoxic plant alkaloid homoharringtonine isolated from the evergreen tree Cephalotaxus, with potential antineoplastic activity. Although the exact mechanism of action has not been fully elucidated, upon administration, omacetaxine targets and binds to the 80S ribosome in eukaryotic cells and inhibits protein synthesis by interfering with chain elongation. This reduces levels of certain oncoproteins and anti-apoptotic proteins. Semisynthetic derivative of harringtonine that acts as a protein synthesis inhibitor and induces APOPTOSIS in tumor cells. It is used in the treatment of MYELOID LEUKEMIA, CHRONIC. See also: Omacetaxine Mepesuccinate (active moiety of). |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (7.93 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 (7.93 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. View More
Solubility in Formulation 3: ≥ 2.5 mg/mL (7.93 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

*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.
