Darovasertib (LXS-196; IDE-196) is a novel, potent, selective and orally bioactive inhibitor of protein kinase C (PKC) with IC50 values of 1.9 nM, 0.4 nM and 3.1 μM for PKCα, PKCθ and GSK3β, respectively. It can be used for the treatment of uveal melanoma. LXS-196 can be potentially used for the treatment of uveal melanoma. After oral administration, protein kinase C inhibitor LXS196 binds to and inhibits PKC, which prevents the activation of PKC-mediated signaling pathways. This may lead to the induction of cell cycle arrest and apoptosis in susceptible tumor cells. PKC, a serine/threonine protein kinase overexpressed in certain types of cancer cells, is involved in tumor cell differentiation, proliferation, invasion and survival.
| ln Vitro |
Following the toxin, PKC is bound by the protein product C-head Darovasertib (LXS196), which inhibits PKC and stops PKC-mediated signal amplifiers from activating. In tumor cells that are vulnerable, this could result in the production of cell cycle candles and HCC. PKC is a serine/threonine protein stall that is overexpressed in some cancer cell types and linked to ischemia, tumor cell sudden death, urogenital tract, and sudden death [1].

| ln Vivo |
In a dose-dependent manner, darovasertib (LXS196; Compound 9) inhibits tumor growth in the 92.1 GNAQ grape melanoma xenograft model [2]. Uveal melanoma cells with a 92.1 GNAQ mutation were implanted into mice [2].

| Animal Protocol |
Animal/Disease Models: Mice implanted with 92.1 GNAQ mutant uveal melanoma cells[2].
Doses: 15, 30, 75, 150 mg/kg Route of Administration: P.O. (bid) for 35 days Experimental Results:Dose-dependently suppressed the tumor growth. |

Solubility in Formulation 1: ≥ 2.5 mg/mL (5.29 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 (5.29 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in 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 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

*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.
