jnj 40346527

Edicotinib (JNJ-527) 是能够透过血脑屏障的、口服具有活性的、选择性的CSF-1R 抑制剂 (IC50:3.2 nM)。它对 KIT (IC50:20 nM) 和 FLT3 (IC50:190 nM) 的抑制作用较小。它抑制小胶质细胞的扩张，减弱小胶质细胞的增殖和神经退行性变。它可用于研究阿尔茨海默病和类风湿性关节炎。

Edicotinib, also known as JNJ-40346527, is a small molecule and orally available inhibitor of colony-stimulating factor-1 receptor (CSF1R; FMS) with potential antineoplastic activity. FMS tyrosine kinase inhibitor JNJ-40346527 blocks the receptor-ligand interaction between FMS and its ligand CSF1, thereby preventing autophosphorylation of FMS. As a result, unphosphorylated FMS cannot activate FMS-mediated signaling pathways, thus potentially inhibiting cell proliferation in FMS-overexpressed tumor cells.

R 93274 is a radioiodinated 5-HT2A receptor antagonist.
