生物活性:
CSF1R-IN-15 (compound 23) is an inhibitor targeting CSF1R. The colony-stimulating factor-1 receptor (CSF1R) is a tyrosine kinase embedded in the cell membrane of macrophages. The receptor is activated by colony-stimulating factor-1 (CSF-1) and interleukin-34, and signaling via CSF1R is crucial for the differentiation, proliferation, and survival of macrophages.

体内研究:
CSF1R-IN-15 体内药代动力学指标来自于盒式给药研究。CSF1R-IN-15 在 C57BLKS 小鼠中的 t1/2,C0,AUC0-∞,CLobs 和 Vss,obs 分别为 0.5 h,37 ng/ml,18 h*ng/ml,54 L/h/kg 和 32 L/k。Animal Model:In Vivo Pharmacokinetic Study
Dosage:1mg/kg
Administration:Intravenous injection (i.v.) single dosing of drugs (1 mg/kg each) in a 20% DMSO, 80% PEG400 formulation. Blood sampling was done after 10, 30, 60, 120, 240, and 480 min.
Result:In vivo pharmacokinetic indexes were t1/2 (0.5 h), C0 (37 ng/mL), AUC0-∞ (18 h*ng/mL), CLobs (54 L/h/kg), and Vss,obs (32 L/kg), respectively.

体外研究:
CSF1R-IN-15 (0.007-10 μM, 72 h) 对 Ba/F3 细胞没有活性,而 pexidartinib (HY-16749) 具有优越的活性。CSF1R-IN-15 对血浆蛋白结合的评估是通过平衡透析法进行的。CSF1R-IN-15 (5 μM, 6 h, 37 °C) 与血浆孵化,与小鼠血浆蛋白结合率为 69%。
