SIAIS164018
SIAIS164018 is a multi-kinase (ALK, EGFR, FAK, PYK2, PTK6) PROTAC degrader, with IC50 values of 2.5 nM and 6.6 nM against ALK and ALK (G1202R), respectively. SIAIS164018 promotes the ubiquitination and degradation of ALK, EGFR, FAK, PYK2 and PTK6. SIAIS164018 induces cell cycle arrest at the G1 phase and triggers cell Apoptosis. SIAIS164018 exhibits preferential inhibitory activity against FER kinase. SIAIS164018 can be used in research related to non-small cell lung cancer, ovarian cancer and triple-negative breast cancer.

Solvent & Solubility
DMSO : 100 mg/mL (113.21 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (2.83 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
