Biological Activity
|
CYP11 |
Compare with the FADs and LCI699, BI 689648 is highly selective in vitro, providing an IC50 for CYP11B2 of 2.1 nM and a selectivity factor of 149 over CYP11B1. FAD286, by comparison, shows a similar IC50 for CYP11B2 (2.5 nM); however, its greater potency against CYP11B1 (94 nM) results in a comparatively modest selectivity factor of 38, approximately 4-fold less than BI 689648[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 (8.38 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 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (8.38 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.

Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
Homogenized adrenal glands are used to evaluate test compounds (including BI 689648) in a 96-well plate format. A mixture of concentrated homogenate and substrate is added to compound dilutions for analysis. Values for the concentration required to inhibit CS (CYP11B1) and AS (CYP11B2) enzyme activity by 50% (IC50) are calculated[1].

For aldosterone synthase inhibitors (ASI) evaluation, the study cohort consists of 66 healthy animals. Each separate study day, 12 cyno monkeys are randomized to receive various doses of ASI or vehicle control (n=3/group); the animals are reused across studies, allowing a minimum of 2 weeks washout between studies. Aggregation of data across multiple studies is used to derive in vivo effective concentration (EC) values for aldosterone and cortisol by curve-fitting. Conscious, nonchaired monkeys receive vehicle (n=35), S-FAD (n=9), FAD286 (n=24), LCI699 (n=36), or BI 689648 (n=26) at doses ranging from 0.003 mg/kg to 10 mg/kg. Maximal adrenocorticotropin (ACTH)-induced aldosterone and cortisol production occurs quickly, within 15 minutes after challenge, at which time blood is collected for plasma aldosterone, cortisol, and test compound concentrations[1].
