生物活性

GTPL5846 (6-OAU) increased [35S]GTPγS incorporated in Sf9 cell membranes expressing human GPR84-Gαi fusion protein with an EC50 of 512 nM. Stimulation with 6.25 μm 6-OAU began to induce GPR84-EGFP internalization, and the extensive internalization was observed at 200 μm 6-OAU stimulation. In a Transwell assay, 3-OH-C12 and the surrogate agonist, GTPL5846 (6-OAU), provoked chemotaxis of PMNs prepared from human peripheral blood in a concentration-dependent manner with an EC50 of 24.2 μm and 318 nm, respectively.

In vivo, injection of GTPL5846 (6-OAU) suspension in 1% rat serum into the rat jugular vein (10 mg/kg) leads to the elevation of a chemokine, CXCL1 concentration in the serum peaking at 3 h after the injection. In the rat air pouch model, GTPL5846 (6-OAU) at 1 mg/ml dissolved in 0.3% BSA attracted both PMNs and macrophages into the air pouch, peaking at 4 h after GTPL5846 inoculation.

化学数据

不同实验动物依据体表面积的等效剂量转换表（数据来源于FDA指南）

例如，依据体表面积折算法，将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量，需要将20 mg/kg 乘以小鼠的K_m系数（3），再除以大鼠的K_m系数（6），得到化合物用于大鼠的等效剂量为10 mg/kg。
