体外研究 | LY2228820作用于RAW 264.7细胞,抑制p38α,和磷酸MAPKAPK-2(pMK2)水平,IC50分别为7 nM 和 34.3 nM。而且, LY2228820作用于小鼠腹腔巨噬细胞,抑制脂多糖 (LPS)-诱导的TNFα形成, IC50为5.2 nM。 200 nM-800 nM LY2228820作用于多发性骨髓瘤(MM)细胞, 包括INA6, RPMI-8226, U266, 和RPMI-Dox40,通过抑制HSP27磷酸化而显著抑制p38MAPK信号, HSP27是p38MAPK下游靶点,不影响 HSP27表达水平。200 nM-400 nM LY2228820增强Bortezomib诱导的细胞毒性和凋亡, 但是LY2228820 单独处理不会抑制MM.1S细胞生长。200 nM-800 nM LY2228820作用于长期骨髓基质干细胞(LT-BMSCs),骨髓单个核细胞(BMMNCs),外周血(PB)CD138 |
体内研究 | LY2228820 作用于LPS诱导的小鼠,有效抑制TNFα 形成,半数有效剂量最小阈值 (TMED 50)小于1 mg/kg。LY2228820 作用于患胶原性关节炎(CIA)大鼠模型,有效作用于足肿胀, 骨质糜烂, 和软骨破坏, 半数有效剂量最小阈值(TMED 50)为 1.5 mg/kg。 |
