Description: Sardomozide (formerly SAM-486A; CGP-48664) is a novel and 2nd-generation polyamine synthesis inhibitor and S-adenosylmethionine decarboxylase (SAMDC) inhibitor with a broad spectrum antiproliferative and antitumor activity. SAM486 is more potent and specific than the first-generation SAMDC inhibitor methylglyoxal (bis) guanylhydrazone (MGBG). Preclinical testing confirmed promising antiproliferative activity. The in vitro tests showed that p53 wild-type NB cells were highly sensitive to SAM486A treatment. Most notably, SAM486A treatment resulted in the rapid accumulation of proapoptotic proteins p53 and Mdm2.

Biological Activity

Targets	IC50: 5 nM (SAMDC)[1]
ln Vitro	An IC50 of 5 nM was observed in a cell experiment for the S-adenosylmethionine decarboxylase (SAMDC) inhibitor sardomozide. After being treated with 3 μM Sardomozide for 48 hours, intracellular SAMDC activity drops to 10% of the control level[1]. Vacuole production is not seen in CHO/664 cells grown in the presence of Sardomozide and treated with DENSPM; instead, the cells exhibit growth inhibition and DENSPM levels comparable to those of the original CHO cells[2].
Cell Assay	The parent CHO cell line is chronically exposed to increasing levels of Sardomozide for at least eight passages beginning at 0.1 μM. Cell lines are serially exposed to increasing concentrations until a panel of sublines is obtained resistant to 1 (CHO/1). 3 (CHO/3), 10 (CHO/10), 30 (CHO/30), and 100 (CHO/100) μM Sardomozide for comparative studies[2].

Additional Infomation	Sardomozide is a methylglyoxal-bis(guanylhydrazone) (MGBG) derivative with potential antineoplastic and antiviral properties. Sardomozide selectively binds to and inhibits S-adenosylmethionine decarboxylase (SAMDC), an enzyme essential for the biosynthesis of polyamines, such as spermine and spermidine that bind to DNA and play critical roles in cell division, cell differentiation and membrane function. By inhibiting SAMDC, sardomozide reduces the intracellular polyamine concentration, thereby interfering with cell growth and differentiation. In addition, this agent also exhibits anti-HIV effect via suppressing expression of eukaryotic translation initiation factor 5A (eIF-5A), which is essential for retroviral replication.

Solubility Data

Solubility (In Vitro)

May dissolve in DMSO (in most cases), if not, try other solvents such as H2O, Ethanol, or DMF with a minute amount of products to avoid loss of samples

Solubility (In Vivo)

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples. Injection Formulations (e.g. IP/IV/IM/SC) Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a 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.
