Serdemetan (formerly JNJ26854165; JNJ-26854165; JNJ 26854165) which was initially created as a p53 activator, is now thought to be a brand-new, powerful, and orally bioactive HDM-2 ubiquitin ligase antagonist with antitumor properties. Additionally, it causes cellular proliferation inhibition and delayed apoptosis in the absence of functional p53. It also causes early apoptosis in p53 wild-type cells.

p53; HDM2; Mdm2

| ln Vitro |
JNJ 26854165 is a novel tryptamine derivative which activates p53 and acts as a HDM2 ubiquitin ligase antagonist. JNJ 26854165 inhibits cell growth and triggers apoptosis in leukemia cell lines, with IC50 values for OCI-AML-3, MOLM-13, NALM-6, and REH cells being 0.24, 0.33, 0.32, and 0.44 M at 72 hours, respectively. JNJ 26854165 also counteracts the transcriptional induction of p21 by p53 and speeds up the proteasome-mediated degradation of p21. Additionally, it delays S-phase and increases the expression of E2F1 in p53 mutant cells, which favors the apoptosis of S-phase cells.[1] JNJ 26854165 is an oral Mdm2 inhibitor that binds to Mdm2's RING domain to prevent the Mdm2-p53 complex from interacting with the proteasome and raise p53 levels.[2]

| ln Vivo |
JNJ 26854165 causes statistically significant differences in the EFS distribution in 5 of 7 (71%) and 17 of 36 (47%) of the evaluable ALL xenografts and 17 of 36 (47%) of the evaluable solid tumor xenografts, respectively. [4]

| Cell Assay |
Fetal calf serum (FCS), which has been heat-inactivated to 10%, is used to maintain cell lines in RPMI 1640 medium. OCI-AML-3, MOLM-13, NB4, and U937 cells come from AML patients, K562 from a CML patient going through a blast crisis, and NALM-6, REH, and P12-ICHIK cells come from patients with chronic myelogenous leukemia.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (7.61 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 (7.61 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

*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.

Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
