| In vitro | Saracatinib also potently inhibits other Src tyrosine kinase family members including c-Yes, Fyn, Lyn, Blk, Fgr, and Lck with IC50 from 4-10 nM. Saracatinib sensitively inhibits Src Y530F NIH 3T3 with IC50 of 80 nM. Saracatinib significantly impairs the invasion of HT1080 cells through a 3-dimensional collagen matrix and completely inhibits EGF-induced cell scattering in NBT-II bladder cancer cells. [1] Saracatinib potent inhibits Src activation in DU145 and PC3 cells, which through inhibition of Y419 phosphorylation. Saracatinib inhibits the growth of prostate cancer including PC3, DU145, CWR22Rv1 and LNCaP, while Saracatinib shows low activity in LAPC-4, PZ-HPV7 and RWPE-1 cells. Saracatinib induces cell cycle arrest at G1/S but not caspase 3 cleavages. Saracatinib also significantly inhibits DU145 and PC3 migration in the Boyden chamber. [2] Saracatinib gives a potent and sustained blockage of AKT and enhancs the sensitivity to irradiation in A549 and Calu-6 cells. [3] Saracatinib inhibits osteoclast in activity, resorption and formation. Saracatinib also reversibly prevents osteoclast precursor migration. [4] | |||||
| In vivo | Saracatinib shows great tumor growth inhibiton in Src3T3 allografts and a moderate growth delay in Calu-6, MDA-MB-231, AsPc-1 and BT474C xenografts. [1] Saracatinib shows great antitumor activity in orthotopic DU145 xenograft mice at a dose of 25mg/kg (orally administered, daily). [2] | |||||
| Clinical Trials | Saracatinib is currently in Phase II clinical trial in recurrent osteosarcoma localized to the lung. | |||||
| Features | Saracatinib is the first Src inhibitor to show inhibition of the Src pathway in human tumor tissue. | |||||
| Kinase Assay | IC50 of tyrosine kinase activity is measured by an enzyme-linked immunosorbent assay (ELISA) with recombinant catalytic domains of a panel of receptor and non-receptor tyrosine kinases (in some cases only part of the catalytic domain is used). Saracatinib dose ranges from 0.001–10 mM. Specificity assays against a panel of serine/threonine kinases are performed using a filter capture assay with 32P. Briefly, multidrop 384 plates containing 0.5 μL Saracatinib or controls (DMSO) alone or pH 3.0 buffer controls) are incubated with 15 μL of enzyme plus peptide/protein substrate for 5 min before the reaction is initiated by the addition of 10 μL of 20 mM Mg-ATP. For all enzymes the final concentration is approximated to the Michaelis constant (Km). Assays are carried out for 30min at room temperature before termination by the addition of 5 μL orthophosphoric acid. After mixing, the well contents are harvested onto a P81 Unifilter plate, using orthophosphoric acid as the wash buffer. Then IC50 is calculated. |

IP assay of tyrosine phosphorylation of VDR in the plasmamembrane. Primary human hepatocytes were treated with Veh, 1α, 25(OH)2-VD3 (50nM), LCA-acetate (10 μM), and/or the c-Src inhibitor AZD0530 (AZD) (5 μM) for 6 h.A rabbit anti-VDR antibody was used to immunoprecipitate VDR from cell membrane extracts (300 μg). A mouse anti-phospho-tyrosine was used to detect phosphotyrosines in VDR. A mouse anti-VDR was used to detect immunoprecipitated VDR. Ten % cell extract was set aside as input. Q-PCR assay of the effects of AZD on CYP7A1,CYP27A1, and CYP24A1 mRNA expression in primary human hepatocytes. Primary human hepatocytes were treated with Veh, 1α, 25(OH)2-VD3 (50 nM), LCA-acetate (10 μM), and/or AZD (5 μM) for 16 h. An $, *, or # indicates statistically significant difference, p < 0.05, AZD-treated versus vehicle control, 1α, 25(OH)2-VD3 or LCAacetate-treated versus vehicle control, or 1α, 25(OH)2-VD3 plus AZD or LCA-acetateplus AZD co-treated versus 1α, 25(OH)2-VD3 or LCA-acetate-treated. All the datarepresent one of three separate experiments using primary human hepatocytes from different liver donors (#HH1479, #HH1483, #HH1493, #HH1524, #HH1560, and#HH1567).
