We report the characterization of BMS-911543, a potent and selective small-molecule inhibitor of the Janus kinase (JAK) family member, JAK2. Functionally, BMS-911543 displayed potent anti-proliferative and pharmacodynamic (PD) effects in cell lines dependent upon JAK2 signaling, and had little activity in cell types dependent upon other pathways, such as(More)
The BET (bromodomain and extra-terminal) proteins bind acetylated histones and recruit protein complexes to promote transcription elongation. In hematologic cancers, BET proteins have been shown to regulate expression of MYC and other genes that are important to disease pathology. Pharmacologic inhibition of BET protein binding has been shown to inhibit(More)
Myeloproliferative disorders (MPDs) are clonal malignancies that arise from hematopoietic progenitors and characterized by overproduction of mature, functional blood cells. These disorders can be broadly characterized into Philadelphia chromosome-positive (Ph(+)) or negative (Ph(−)) genetic groupings. Chronic myeloid leukemia (CML) is a Ph(+) MPD that is(More)
CARM1 (co-activator-associated arginine methyltransferase 1) is a PRMT (protein arginine N-methyltransferase) family member that catalyses the transfer of methyl groups from SAM (S-adenosylmethionine) to the side chain of specific arginine residues of substrate proteins. This post-translational modification of proteins regulates a variety of transcriptional(More)
The chemokine receptor CCR4 is broadly expressed on cells of the immune system. It is known to play a central role in T cell migration to the thymus, and T cell maturation and education. In addition, CCR4 is known to modulate T cell migration to several sites of inflammation in the body, including the skin, and lungs. It is best known as a drug target for(More)
