R406R406是一种有效的Syk抑制剂，无细胞试验中IC50为41 nM，对Syk抑制作用强，但是不抑制Lyn，对Flt3的作用比对Syk低5倍。Phase 1。 |
Platelets (3 x 108/mL) were preincubated with Y27632 (10 uM), R406 (1 uM), or a combination of Y27632 and R406 for 20 minutes followed by stimulation with oxLDL (50 ug/mL) for 15 seconds and lysis. Samples were then separated by SDS-PAGE and were immunoblotted for phospho-MLCSer19, followed by reprobing for β-tubulin. (Fi) Representative blots. (Fii) Densitometric analysis of 3 independent experiments. *P < .05. Data are presented as mean ± SEM. Experiments were carried out in the presence of apyrase (2 U/mL), indomethacin (10 uM), and EGTA (1 mM).

(C) Z-138 and JEKO-1 cells were simultaneously exposed to sorafenib and R406 at the indicated doses, and cell viability was determined at 48 hours by annexin V/PI staining. Bars represent the mean ± SD of 3 independent experiments. CI value is indicated for each combination. (D) Primary MCL cells from 7 patients were simultaneously exposed to sorafenib and R406 at the indicated doses for 48 hours, and cell viability was determined as above. Bars represent the mean ± SEM of all the samples analyzed. CI value is indicated for each combination. |
