Mechanism of Action

Targets/IC₅₀/Ki	FAK 0.4 nM(Ki)
In vitro	GSK2256098 has been developed to inhibit FAK activity through targeting the phosphorylation site of FAK, tyrosine (Y) 397. After a 30-min incubation, this compound inhibits FAK activity or Y397 phosphorylation in cancer cell lines, OVCAR8 (ovary), U87MG (brain), and A549 (lung), at IC50 values of 15, 8.5 and 12 nM, respectively. In addition, the data suggests that cellular inhibition of FAK by this chemical can occur as early as 30 min in cultured cells and lasts up to 12 hours in mouse tumor xenografts. Its inhibition of FAK kinase activity can decrease Akt and ERK activity. PI3K/Akt and ERK signaling contributes to cell survival, implying a pharmacological value of this compound in attenuation of abnormal survival pathways in specific types of PDAC cells. It can promote apoptosis in L3.6P1 cells through caspase-9/PARP-related pathways. It attenuates abnormal growth and aberrant motility of PDAC cells in a FAK specific manner. This compound also inhibits growth, migration, and invasion and induces apoptosis in a subset of GBM cell lines.
In vivo	Pharmacokinetic (PK) studies in mice and rats with an intact blood brain barrier indicate that the penetration of GSK2256098 into the CNS is poor. However, it achieves concentrations in tumor of patients with GBM(glioblastoma) exceeding those associated with preclinical activity. This compound has an acceptable safety profile, has evidence of target engagement at doses at or below the MTD (maximum tolerated dose), and has clinical activity in patients with mesothelioma, particularly those with merlin loss. In the Ishikawa orthoptopic murine model, treatment with this compound results in lower tumor weights and fewer metastases than mice inoculated with Hec1A cells. Tumors treated with this chemical have lower microvessel density (CD31), less cellular proliferation (Ki67), and higher apoptosis (TUNEL) rates in the Ishikawa model when compared to the Hec1a model. It may be therapeutically beneficial to patients with PTEN-mutant uterine cancer, and PTEN represents a potential predictive biomarker.
