EAI045 is a fourth generation allosteric inhibitor of mutant EGFR, which inhibits EGFR at 10 μM ATP, EGFRL858R, EGFRT790M and EGFRL858R/T790M with IC50 values of 1.9, 0.019, 0.19 and 0.002 μM respectively.
| Cell Experiment | |
|---|---|
| Cell lines | H1975, H3255 and HaCaT cell lines |
| Preparation method | H1975, H3255 and HaCaT cell lines are plated in solid white 384-well plates at 500 cells per well in 10% FBS RPMI penicillin/streptomycin media. Using a Pin Tool, 50 nl of serial diluted compounds are transferred to the cells. After 3 days, cell viability is measured. |
| Concentrations | Serial dilution (0-100 μM) |
| Incubation time | 3 days |
| Animal Experiment | |
|---|---|
| Animal models | EGFR(TL) (bearing L858R/T790M point mutations) and EGFR(TD) (bearing exon19del/T790M point mutations) mice |
| Formulation | 10% NMP (10% 1-methyl-2-pyrrolidinone:90% PEG-300) |
| Dosages | 60 mg/kg |
| Administration | oral gavage |
| Molecular Weight | 383.40 |
| Formula | C19H14FN3O3S |
| CAS Number | 1942114-09-1 |
| Solubility (25°C) | 76 mg/mL in DMSO |
| Storage |
Powder -20°C 3 years ; 4°C 2 years In solvent -80°C 6 months ; -20°C 1 month |
| Species | Mouse | Rat | Rabbit | Guinea pig | Hamster | Dog |
| Weight (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
| Body Surface Area (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
| Km factor | 3 | 6 | 12 | 8 | 5 | 20 |
| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
