LM-189
LM-189 is a β2-adrenergic receptor (β2AR) ligand and G protein-biased modulator with a human β2AR Ki of 0.063 nM.LM-189 promotes β2AR coupling to Gαs and Gαi heterotrimers, stabilizes distinct β2AR conformations including a TM6 outward state, and increases β2AR ICL2 dynamics.LM-189 restricts β2AR ligand-binding pocket conformational heterogeneity, stabilizes polar ligand-receptor interaction networks, and exhibits bias toward Gαi signaling over Gαs signaling.LM-189 enabled cryo-EM structural characterization of the β2AR-Gi complex.LM-189 can be used for the research of congestive heart failure.

β2 adrenoceptor 0.063 nM (Ki) |
Beta-1 adrenergic receptor 28 nM (Ki) |
LM-189 exhibits extremely high affinity for human β2-adrenergic receptors in HEK-293T cell membranes (Ki=0.063 nM), and shows low affinity for human β1-adrenergic receptors (Ki=28 nM)[1].
LM-189 (75 μM; protected from light; 1 h) stabilizes a unique conformation of the β2-adrenergic receptor; the outward movement amplitude of transmembrane helix 6 (TM6) or the proportion of the active state of this conformation is higher than that induced by the full agonist BI-167107 (HY-121251)[1].

DMSO : 100 mg/mL (193.96 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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 (4.85 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 (4.85 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.

Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
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.
