Formyl Peptide Receptor 2 (FPR2)：BMS-986235 is a selective agonist with EC50 values of 0.41 nM for human FPR2 (hFPR2) and 3.4 nM for mouse FPR2 (mFPR2). It shows >6,800-fold selectivity over human FPR1 (IC50 > 2,800 nM). [1]

| ln Vitro |
In order to promote the resolution of inflammation, BMS-986235 (LAR-1219) inhibits neutrophil chemotaxis and increases macrophage phagocytosis [1].
- Neutrophil chemotaxis inhibition：BMS-986235 dose-dependently inhibits neutrophil migration induced by the FPR2 agonist WKYMVm, with an IC50 of 0.12 μM in Transwell assays. [1] - Macrophage phagocytosis stimulation：The compound enhances phagocytosis of fluorescently labeled Escherichia coli by macrophages, with a maximal response at 10 nM (2.3-fold increase compared to vehicle control). [1] - G protein activation and β-arrestin recruitment：In HEK293 cells transfected with hFPR2, BMS-986235 triggers Gαi protein activation (measured via cAMP inhibition) and β-arrestin2 recruitment (assessed by bioluminescence resonance energy transfer), with EC50 values of 0.35 nM and 0.82 nM, respectively. [1] |
| ln Vivo |
Following the left anterior descending artery (LAD) in mice, BMS-986235 (LAR-1219) (0.3 mg/kg; oral; once daily for 24 days) decreases left ventricular and overall cardiac remodeling[1]. Cmax, T1/2, AUC0-inf, and bioavailability (BA) values of 160 nmol/L, 0.68 h, and 120 nmol/L were observed with BMS-986235 (1 mg/kg; po) therapy.h, and 24%, in that order[1].
Cardiac remodeling attenuation in mice：Oral administration of BMS-986235 (0.3 mg/kg daily for 24 days) to C57BL/6 mice post-myocardial infarction (MI) reduces left ventricular (LV) chamber dilation by 39% and increases LV ejection fraction by 18% compared to vehicle. Infarct size is decreased by 27% as measured by triphenyltetrazolium chloride (TTC) staining. [1] - Pharmacokinetics in mice：After oral dosing (1 mg/kg), BMS-986235 achieves a Cmax of 160 nM within 0.68 hours, with a plasma half-life of 0.68 hours and oral bioavailability of 24%. Plasma protein binding exceeds 99%. [1] |
| Enzyme Assay |
- FPR2 agonist activity assay：
1. HEK293 cells stably expressing hFPR2 are loaded with a calcium-sensitive dye and stimulated with BMS-986235 (0.01–100 nM).
2. Intracellular calcium mobilization is measured via fluorescence microscopy, with EC50 values calculated from dose-response curves. [1]
- G protein activation assay： 1. Membrane fractions from hFPR2-expressing cells are incubated with BMS-986235 and [³⁵S]GTPγS. 2. G protein activation is quantified by scintillation counting, with EC50 values determined for Gαi subunit activation. [1] |

- Neutrophil chemotaxis assay：
1. Human neutrophils are suspended in migration buffer and added to Transwell inserts.
2. BMS-986235 (0.01–10 μM) or WKYMVm (positive control) is added to the lower chamber.

C57BL/6 mice (8–10 weeks old) undergo left anterior descending (LAD) coronary artery ligation to induce MI. 2. Starting 24 hours post-MI, BMS-986235 is administered orally at 0.3 mg/kg daily for 24 days. 3. Cardiac function is assessed by echocardiography at baseline and post-treatment. [1] - Pharmacokinetic study： 1. BALB/c mice receive a single oral dose of BMS-986235 (1 mg/kg) dissolved in a formulation of 10% DMSO, 40% PEG 300, 5% Tween-80, and 45% saline. 2. Plasma samples are collected at 0.25, 0.5, 1, 2, 4, 8, and 24 hours post-dose. 3. Drug concentrations are measured by liquid chromatography-tandem mass spectrometry (LC-MS/MS). [1] |
| ADME/Pharmacokinetics |
- Absorption：Rapid oral absorption with Tmax of 0.68 hours in mice. [1]
- Distribution：High plasma protein binding (>99%) limits free drug concentration. [1] - Metabolism：Primarily metabolized via oxidation and glucuronidation in the liver. <5% of the dose is excreted unchanged in urine and feces. [1] - Half-life：0.68 hours in mice, supporting once-daily dosing. [1] |
| Toxicity/Toxicokinetics |
- Acute toxicity：No mortality or adverse effects are observed in mice at single oral doses up to 1,000 mg/kg. [1]
- Subchronic safety：Daily oral dosing of BMS-986235 (0.3–30 mg/kg) for 28 days in rats shows no significant changes in hematology, clinical chemistry, or organ weights. [1] |

| Additional Infomation |
- Mechanism of action：BMS-986235 activates FPR2 to promote pro-resolution macrophage phenotypes (e.g., increased arginase-1 and CD206 expression) and neutrophil apoptosis, thereby resolving inflammation post-MI. [1]
- Therapeutic potential：Investigated for preventing heart failure progression post-MI by enhancing wound healing and limiting maladaptive remodeling. [1] - Formulation：Administered orally as a suspension in DMSO/PEG 300/Tween-80/saline for preclinical studies. [1] |

*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.
