ilk-in-2

ILK-IN-2 (OSU-T315) is a novel potent, orally active ILK (integrin-linked kinase) inhibitor with IC50 of 0.6 μM.

QLT0267 is an inhibitor targeting integrin-linked kinase (ILK; IC50= 26 nM), showing over 10-fold selectivity against cyclin-dependent kinases 1, 2, and 5 (Cdk1, Cdk2, and Cdk5), and over 1,000-fold selectivity against C-terminal Src kinase (CSK), DNA-PK, Pim-1, Akt, PKC, and casein kinase 2 (CK2) at a concentration of 10 mg/ml. This compound effectively inhibits the proliferation of NPA187 papillary thyroid cancer cells with an IC50 of approximately 3 µM and induces apoptosis in NPA187, DRO, and K4 cancer cell lines. In vivo studies reveal that QLT0267, administered at 100 mg/kg, significantly reduces tumor growth in a DRO mouse xenograft model and diminishes both tumor volume and intratumoral vascularization in a U87MG glioblastoma mouse xenograft model, showcasing its potential for therapeutic applications in cancer treatment.
