Biological Activity

Targets	EGFR L858R 0.147 nM (IC50) EGFR L858R/T790M 0.063 nM (IC50) EGFR L858R/T790M/C797S 0.083 nM (IC50) EGFRLT/L747S 0.396 nM (IC50)
ln Vitro	Despite the fact that JBJ-09-063 significantly increases apoptosis and is remarkably effective at inhibiting cell growth, H3255GR cells exhibit resistance to gefitinib when administered alone due to an EGFR T790M mutation[1]. When osimertinib-resistant mutations are expressed exogenously in H1975 cells, JBJ-09-063 is efficacious[1]. When JBJ-09-063 is used either by itself or in conjunction with cetuximab, Ba/F3 cells show IC50s of 50 nM and 6 nM [2].
ln Vivo	JBJ-09-063 (3 mg/kg iv, 20 mg/kg po) has favorable pharmacokinetic characteristics and is stable enough to provide good oral dosage results[2].
Animal Protocol	Animal/Disease Models: Mice[2] Doses: 3 mg/kg for iv, 20 mg/kg for po Route of Administration: iv and po; single dosage Experimental Results: pharmacokinetic/PK Parameters of JBJ-09-063 in mice[2]. Cl (mL/min/kg), iv T1/2 (h) Vss (L/kg) F (%) AUC 8h (ng·h/mL) 15.7 2.3 2.5 15 2398

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) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) 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). Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] *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.

Oral Formulation 3: Dissolved in PEG400 Oral Formulation 4: Suspend in 0.2% Carboxymethyl cellulose Oral Formulation 5: Dissolve in 0.25% Tween 80 and 0.5% Carboxymethyl cellulose Oral Formulation 6: Mixing with food powders 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.)
