Description

BI 689648 is a novel, highly selective aldosterone synthase inhibitor which can inhibit CYP11B1 and CYP11B2 with IC50s of 310 and 2.1 nM, respectively.

IC50 & Target

CYP11

 

In Vitro

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].

In Vivo

After oral administration in cyno monkeys, BI 689648 (5 mg/kg) exhibits a peak plasma concentration of ~500 nM. For BI 689648 (aldosterone EC50=2 nM), appreciable changes in 11-DOC are only noted at plasma concentrations >2000 nM or >1000-fold its aldosterone EC50 while FAD286 shows a window of ~100-fold. BI 689648 exhibits minimal impact on 11-DC and only at very high plasma concentrations (~10 μM)[1].

In Vivo:

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.

  • Protocol 1

    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.
  • Protocol 2

    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.

Cell Assay
[1]

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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Animal Administration
[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].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
