Olafertinib, formerly known as CK-101 and Olafertinib, is a potent and orally bioavailable EGFR mutant-specific inhibitor. CK-101 specifically and covalently binds to and inhibits specific EGFR mutations, with particularly high selectivity against the T790M mutation; this prevents EGFR mutant-mediated signaling and leads to cell death in EGFR mutant-expressing tumor cells. Compared to some other EGFR inhibitors, CK-101 may have therapeutic benefits in tumors with T790M-mediated drug resistance. References:

| Additional Infomation |
CK-101, an EGFR mutation-specific inhibitor, is an orally administered third-generation selective EGFR inhibitor that inhibits certain activating mutations of the epidermal growth factor receptor (EGFR), including resistance mutations T790M, L858R, and del 19, and possesses potential antitumor activity. After administration, CK-101 specifically covalently binds to and inhibits specific EGFR mutations, exhibiting particularly high selectivity for the T790M mutation, thereby blocking EGFR mutation-mediated signaling and ultimately leading to the death of tumor cells expressing EGFR mutations. Compared to some other EGFR inhibitors, CK-101 may offer a therapeutic advantage against T790M-mediated resistant tumors. This drug exhibits very low activity against wild-type EGFR (WT EGFR) and does not cause the dose-limiting toxicities associated with the use of non-selective EGFR inhibitors (which also inhibit WT EGFR). EGFR is a receptor tyrosine kinase that is mutated in various tumor cell types and plays a crucial role in tumor cell proliferation and tumor angiogenesis.

| Solubility (In Vitro) |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (3.92 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 20.8 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: ≥ 2.08 mg/mL (3.92 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (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 20.8 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. (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.
Calculation results
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.
