Adenosine kinase is the key metabolizing enzyme regulating cellular adenosine concentrations. Inhibition of adenosine kinase can selectively enhance the protective actions of adenosine during tissue trauma without producing the nonspecific effects associa
A-286501 is an orally active adenosine kinase inhibitor (IC50=0.47 nM). A-286501 effectively attenuates nociception by a non-opioid, non-non-steroidal anti-inflammatory drug ADO, receptor mediated mechanism.
RO5068760 , a substituted hydantoin, is a potent, highly selective, non-adenosine triphosphate (ATP)-competitive MEK1 2 inhibitors. RO5068760 shows significant efficacy in a broad spectrum of tumors with aberrant mitogen-activated protein kinase pathway activation. In vitro, RO5068760 demonstrates MEK1 kinase inhibitory activity with an IC50 of 0.025 μM in a cRaf MEK ERK cascade assay RO5068760 showed superior efficacy in tumors harboring B-RafV600E mutation.
AP23464 is a potent adenosine 5'-triphosphate (ATP)-based inhibitor of Src and Abl kinases, displays antiproliferative activity against a human CML cell line and Bcr-Abl-transduced Ba F3 cells (IC(50) = 14 nM. AP23464 ablates Bcr-Abl tyrosine phosphorylation, blocks cell cycle progression, and promotes apoptosis of Bcr-Abl-expressing cells. Biochemical assays with purified glutathione S transferase (GST)-Abl kinase domain confirmed that AP23464 directly inhibits Abl activity. Importantly, the low nanomolar cellular and biochemical inhibitory properties of AP23464 extend to frequently observed imatinib mesylate-resistant Bcr-Abl mutants, including nucleotide binding P-loop mutants Q252H, Y253F, E255K, C-terminal loop mutant M351T, and activation loop mutant H396P. AP23464 was ineffective against mutant T315I, an imatinib mesylate contact residue. The potency of AP23464 against imatinib mesylate-refractory Bcr-Abl and its distinct binding mode relative to imatinib mesylate warr......
