Avrainvillamide ((+)-Avrainvillamide) is a naturally occurring alkaloid with antiproliferation effects that binds to the nuclear chaperone nucleophosmin, an oncogenic protein overexpressed in many different human tumors. Avrainvillamide affects cell biology by binding directly to NPM1 and Crm1 and by inhibiting the binding of these proteins to certain natural cellular partners. The antibiotic Avrainvillamide, also an antibiotic, suppresses the growth of multidrug-resistant Staphylococcus aureus, Streptococcus pyogenes and Enterococcus faecalis, with MICs of 12.5, 12.5 and 25 μg/ml respectively.

Biological Activity

ln Vitro

Avrainvillamide ((+)-Avrainvillamide) exhibits antiproliferative activities in T-47D (breast cancer) cells and LNCaP (prostate cancer) cells with GI50s of 0.33 and 0.42 μM, respectively. It also restores nucleolar localization of certain acute myeloid leukemia (AML)-associated mutant forms of NPM1 and provides evidence that this relocalization is mediated by interactions of Avrainvillamide with mutant NPM1 and exportin-1 (Crm1)[2].

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.

InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently.  (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.
