Y15 is a potent and specific inhibitor of focal adhesion kinase (FAK) that inhibits its autophosphorylation activity, decreases the viability of cancer cells, and blocks tumor growth.

FAK^[1]

Y15 directly blocks autophosphorylation activity of FAK. Y15 inhibits Y397 phosphorylation of FAK starting at 0.1 μM in Panc-1 cells. At a dose of 100 μM, Y15 has the same or better inhibition as TAE226. Of note, total FAK is downregulated at higher doses of Y15. Y15 also blocks phosphorylation of the FAK downstream substrate, paxillin. Total paxillin is decreased at higher doses similar to FAK. Thus, Y15 inhibits FAK phosphorylation in a dose-dependent manner^[1]. MTS assay is completed using a range of Y15 doses on all cell lines (TT, K1, BCPAP, and TPC1, respectively).Y15 inhibited cell viability in a dose-dependent manner across all thyroid cell lines evaluated. IC₅₀ is 2.05, 5.74, 9.99, and 17.54 μM for TT, TPC1, BCPAP, and K1, respectively^[2].

Nude mice bearing Panc si-ctrl xenografts are treated with TAE226, a dual FAK and IGF-1R tyrosine kinase inhibitor, to provide a reference for the antitumor effect of dual inhibition of FAK and IGF-1R. Without drug treatment, Panc si5-IGF-1R xenografts grew slower than Panc si-ctrl xenografts (Panc si5-IGF-1R/PBS vs. Panc si-ctrl/PBS), suggesting moderate tumor suppression by inhibiting the IGF-1R pathway only. Further inhibition of FAK activity by Y15 treatment suppresses the growth of Panc si5-IGF-1R xenografts more drastically (Panc si5-IGF-1R/PBS vs. Panc si5-IGF-1R/Y15). A similar antitumor effect is seen in Panc si-ctrl xenografts treated with TAE226 (Panc si5-IGF-1R/Y15 vs. Panc si-ctrl/TAE226). Mice demonstrates normal grooming and eating habits throughout the experiment^[3].

10 μCi of [γ-³²P]-ATP in a kinase buffer 20 mM HEPES, pH 7.4, 5 mM MgCl₂, 5 mM MnCl₂, 0.1 mM Na₃VO₄ with 0.1 μg of purified FAK protein are incubated in a kinase buffer with 10 μCi of [γ-³²P]-ATP. The kinase reaction is performed for 5 minutes at room temperature and stopped by addition of 2× Laemmli buffer. Proteins are separated on a Ready SDS-10% PAGE gel, and the phosphorylated enolase is visualized by autoradiography^[1]

The cells are treated with Y15 or TAE226 at different concentrations for 24 hours. The 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium compound from Promega Viability kit is added, and the cells are incubated at 37°C for 1-2 hours. The optical density on 96-plate is analyzed with a microplate reader at 490 nm to determine cell viability. In addition, cells are stained with trypan blue after 24 hours of treatment with Y15 and the percent of cells that stained positive are determined with a hemacytometer^[1]

Mice^[3]
Six-week-old, female nude mice are used. 5×10⁶ Panc si5-IGF-1R cells are mixed with matrigel and injected subcutaneously into the flank of athymic nude mice (day 0). Animals are randomly divided into two groups on day 7. One group (n=5) received Y15 (30 mg/kg) and the other received PBS as control treatment (n=5). For Panc si-ctrl xenografts, 5×10⁶ Panc si-ctrl cells are mixed with matrigel and injected subcutaneously into the flank of nude mice. These animals are also randomly divided into two groups on day 7, and one group (n=5) received TAE226 (30 mg/kg), the other group received PBS (n=5) as control treatment. The drugs and PBS are administered through intraperitoneal injection in a total volume of 0.1 mL. Tumor sizes are measured every 3 or 4 d in length (mm)×width (mm) starting from day 10. Tumor volume is calculated as volume (cm³)= 1/2×length (cm)×width(cm)².
