ARS-1630 (ARS1630) is the less active isomer of ARS-1620, which is a novel and potent inhibitor of mutant K-ras G12C found in patent WO 2015054572 A1. It might possess anticancer properties.
| Targets |
KRAS(G12C)
|
|---|---|
| ln Vitro |
Recent research has revealed that KRASG12C may be druggable through allele-specific covalent targeting of Cys-12 close to an inducible allosteric switch II pocket (S-IIP). Since the S-IIP is only accessible in the GDP-bound state, the effectiveness of this strategy depends on KRASG12C actively cycling between its active-GTP and inactive-GDP conformations. In vitro, this approach shows promise for suppressing mutant KRAS [2].

| Additional Infomation |
ARS-1620 is a qinazoline derivative carrying chloro and fluoro substituents at positions 6 and 8 respectively, a 2-fluoro-6-hydroxyphenyl group at position 7, and a 4-(prop-2-enoyl)piperazin-1-yl group at position 4. A potent, selective, and orally bioavailable covalent KRAS-G12C inhibitor, it inhibits the protein coding gene KRAS (Kirsten rat sarcoma virus) with high potency in cells and animals. It has a role as an inhibitor, an antiviral agent and an antineoplastic agent.

| Solubility (In Vitro) |
DMSO: ≥ 100 mg/mL (~232.1 mM)

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (5.80 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 (5.80 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. 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
Solubility in Formulation 3: ≥ 2.5 mg/mL (5.80 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

*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.
