Osilodrostat phosphate
Based on 4 publication(s) in Google Scholar
Osilodrostat (LCI699) phosphate is a potent, orally active11β-hydroxylase (CYP11B1) inhibitor with an IC50 value of 35 nM. Osilodrostat phosphate is a potent, orally aldosterone synthase (CYP11B2) inhibitor with IC50 values of 0.7 nM and 160 nM for human aldosterone synthase and rat aldosterone synthase, respectively. Osilodrostat phosphate inhibits aldosterone and corticosterone synthesis. Osilodrostat phosphate has blood pressure lowering ability. Osilodrostat phosphate can be used for research of Cushing syndrome (CS).

Biological Activity
IC50: 35 nM (CYP11B1), 0.7 nM (human aldosterone synthase), and 160 nM (rat aldosterone synthase)[1][2]
Osilodrostat (LCI699; 0.01-10 μM; HAC15 cells, 17 primary human adrenocortical cell cultures, and pituitary adenoma cells) phosphate inhibits cortisol and aldosterone. Osilodrostat results in inhibition of corticosterone, 11-deoxycortisol accumulation, and modest effects on adrenal androgens[2].

Osilodrostat (LCI699; 3-100 mg/kg; p.o.; daily, for 52 weeks) phosphate reduces mean arterial pressure and prolongs survival in dTG rats[1].

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 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (7.69 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
