In vitro study | Saracatinib also potently inhibits other Src tyrosine kinase family members, including c-Yes, Fyn, Lyn, Blk, Fgr, and Lck, with an IC50 of 4 to 10 nM. Saracatinib effectively inhibited SrcY530F mutated NIH 3T3 cells with an IC50 of 80 nM. In NBT-II bladder cancer cells, Saracatinib significantly blocked the invasion of HT1080 cells through the three-dimensional collagen matrix and completely inhibited EGF-induced cell dispersal. Saracatinib acts on DU145 and PC3 cells and effectively inhibits Src activation by inhibiting Y419 phosphorylation. Saracatinib inhibited the growth of prostate cancer cells including PC3, DU145, CWR22Rv1, and LNCaP, whereas Saracatinib showed low activity on LAPC-4, PZ-HPV7, and RWPE-1 cells. Saracatinib stops the cell cycle at the G1/S stage, but does not break caspase 3. Saracatinib also significantly inhibited the movement of DU145 and PC3 in The Boyden chamber. Saracatinib potently and persistently inhibits Akt and enhances the sensitivity of A549 and Calu-6 cells to radiation treatment. Saracatinib inhibits osteoblasts in activity, resorption, and composition. Saracatinib also reversibly blocked the movement of osteoblast precursors. |
