Abstract 2542: TG02, a novel multi-kinase inhibitor with potent anti-leukemic activity (original) (raw)

Cancer Research, 2010

Abstract

Kinase inhibitors have found applications in multiple oncology settings due to their ability to target key signaling pathways in many different cancers. In general, the broad-spectrum kinase inhibitors have yielded better clinical outcomes than more selective ones because they block more than one pathway critical for tumor growth. We describe herein the pharmacological profile of TG02, a multi-kinase inhibitor being developed by Tragara Pharmaceuticals, which combines cell cycle regulatory and transcriptional CDK inhibition with activity against kinase targets important in the etiology of various leukemias. In vitro potency against the kinases was evaluated using recombinant enzymes with synthetic substrates. Potency on intracellular signaling pathways was assessed by Western blot analyses of the phosphorylated substrates in cell lysates. Functional potency was assessed using proliferation assays performed on human tumor cell lines as well as hematopoietic progenitors expanded from ...
