Orally active, potent and selective mitogen-activated protein kinase (MAPK) p38alpha (p38α, MAPK14) inhibitor in vitro and in vivo.
SCIO-469 (Talmapimod) is an orally active, potent and selective mitogen-activated protein kinase (MAPK) p38alpha (p38α, MAPK14) inhibitor (IC50 = 9 nM; 10-fold over p38β, >2000-fold over 20 other kinases) with no significant affinity toward a panel of 70 enzymes and receptors. SCIO-469 inhibits multiple myeloma (MM) growth in mice in vivo (150 or 450 mg/kg powder diet; 5T2MM and 5T33MM) and augments proteasome inhibitor in a murine plasmacytoma model of MM (0.2 mg bortezomib/kg i.v. twice weekly with 30 mg SCIO-469/kg b.i.d. p.o.; RPMI8226).
Myelodysplastic syndromes (MDS) are common causes of ineffective hematopoiesis and cytopenias in the elderly. Various myelosuppressive and proinflammatory cytokines have been implicated in the high rates of apoptosis and hematopoietic suppression seen in MDS. We have previously shown that p38

Paclitaxel-based chemotherapy is a common strategy to treat patients with triple-negative breast cancer (TNBC). As paclitaxel resistance is still a clinical issue in treating TNBCs, identifying molecular markers for predicting pathologic responses to paclitaxel treatment is thus urgently needed. Here
Thyroid stimulating hormone (TSH) stimulates the secretion of thyroid hormones by binding the TSH receptor (TSHR). TSHR is well-known to be expressed in thyroid tissue, excepting it, TSHR has also been expressed in many other tissues. In this study, we
