The Bcr-Abl tyrosine kinase oncogene causes chronic myelogenous leukemia (CML) and Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL). We describe a novel selective inhibitor of Bcr-Abl, AMN107 (IC50 <30 nM), which is significantly more potent than imatinib, and active against a number of imatinib-resistant Bcr-Abl mutants.(More)
NVP-LAQ824 is a novel potent hydroxamic acid-derived histone deacetylase inhibitor that induces apoptosis in nanomolar concentrations in myeloid leukemia cell lines and patient samples. Here we show the activity of NVP-LAQ824 in acute myeloid leukemia cells and BCR/ABL-expressing cells of mouse and human origin, both sensitive and resistant to imatinib(More)
A soluble c-type cytochrome was purified to homogeneity from Thiobacillus ferrooxidans. This cytochrome is characterised by an alpha-peak wavelength of 552 nm, a molecular mass of 21 193 Da (as determined by mass spectroscopy), and a pI value of 9. N-terminal sequencing yielded the polypeptide sequence up to the 50th residue. The iron content of 1.9(More)
The sequence of the cyc1 gene encoding the Thiobacillus ferrooxidans ATCC 33020 c552 cytochrome, shows that this cytochrome is a 21-kDa periplasmic c4-type cytochrome containing two similar monohaem domains. The kinetics of reduction and the fact that cytochromes c4 are considered to be physiological electron donors of cytochrome oxidases suggest that the(More)
