HDM201 R Enantiomer 1448867-42-2_Others_Signaling Pathways_Products

HDM201 R Enantiomer is the R enantiomer of HDM201 (also called NVP-HDM201, HDM stands for 'human double minute 2 homolog'). HDM201 is an orally bioavailable, highly potent and selective inhibitor of the p53-Mdm2 protein-protein interaction. It has high affinity for Mdm2 in the picomolar range and a selectivity ratio of more than 10000-fold vs Mdm4. HDM201 is currently undergoing phase I clinical trial for cancer treatment. HDM201 inhibits the binding of the HDM2 protein to the transcriptional activation domain of the tumor suppressor protein p53. By preventing this HDM2-p53 protein-protein interaction, the proteosome-mediated enzymatic degradation of p53 is inhibited, which results in the restoration of both p53 signaling and p53-mediated induction of tumor cell apoptosis.

Biological Activity

ln Vitro

In vitro activity: HDM201 acts by binding to the p53 binding-site of the Mdm2 protein, thereby disrupting the interaction of the two proteins (p53 and Mdm2) and leading to the activation of the p53 pathway. It induces robust p53-dependent cell cycle arrest and apoptosis in human p53 wild-type tumor cells. HDM201 exhibits highly selectivity across a panel of cancer cell lines

Kinase Assay:

Cell Assay: The in vitro combination screen was performed at Horizon Discovery (Cambridge, MA) on cancer cell lines, and data analysis was performed as described previously. Here we focused the data analysis on combinations with CGM097, a previous class of selective TP53-MDM2 inhibitors. A total of 485 cancer cell lines were treated with varying concentrations of CGM097 and for 25 other compounds. We integrated the information on TP53 mutation status and differentiated cell lines with no TP53 mutation from cell lines with TP53 alteration. We assessed the synergistic effect of combinations of HDM201and A-1155463 as described previously.

ln Vivo

Treatment was initiated when the tumors engrafted in the flank were at least 150 mm3. Random enrollment was applied. Efficacy studies, tumor response, and relapse were reported with the measures of tumor volumes at the start of treatment. HDM201 was administered at 100 mg/kg in 0.5% methylcellulose and 0.1% Tween 80 orally twice a week, with alternating intervals of 3 d and 4 d. Vehicle was generated according to the formulation. Treatments were administered in the morning.

Animal Protocol

HDM201 was administered at 100 mg/kg in 0.5% methylcellulose and 0.1% Tween 80 orally twice a week

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.
Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline)

Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Note: Please be aware that the above formulations are for reference only. 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.)

Preparing Stock Solutions		1 mg	5 mg	10 mg
	1 mM	1.8005 mL	9.0024 mL	18.0047 mL

*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.
