APS-2-79 is a KSR-Dependent Antagonist of RAF-Mediated MEK Phosphorylation
Deregulation of the Ras-MAPK pathway is an early event in many different cancers and a key driver of resistance to targeted therapies. Kinase suppressor of Ras (KSR) is a MAPK scaffold. KSR exhibits allosteric regulation through dimerization with RAF. In this study, researchers developed a class of compounds that...
IMT1 is a First-in-Class Specific and Noncompetitive Human POLRMT Inhibitor
Mitochondria provide cellular energy through its oxidative phosphorylation system, which needs to coordinate the expression of genes encoded by nuclear and mitochondrial genomes (mtDNA). Specifically, the transcription of mtDNA in circular mammals depends on a single mitochondrial RNA polymerase (POLRMT). Besides, three proteins are required for mitochondrial transcription initiation:...
CXD101 is a Selective and Orally Active Class I HDAC Inhibitor
Aberrant expression of classical HDACs associates with a variety of malignancies, including solid and hematological tumors. HDACs have also been found broadly dysregulated in multiple myeloma (MM). In particular, the mechanisms that HDACs regulate tumorigenesis are quite diverse. HDACs induce a range of cellular and molecular effects through the...
MCP110 is an Inhibitor of Ras/Raf-1 Interaction
Ras is a small GTPase and interacts with the protein Raf to create activated Ras-Raf complex that activates the downstream effectors in the ERK pathway. Malfunctioning Ras-Raf switches cause cancer. Ras-Raf interaction has taken a center stage in cancer research. Ras is a peripheral membrane protein that acts as...
DM-01 is a Powerful and Selective EZH2 Inhibitor
Enhancer of zeste homolog 2 (EZH2) is a histone methyltransferase and a catalytic component of polycomb repressive complex 2 (PRC2). EZH2 catalyzes tri-methylation of histone H3 at Lys 27 (H3K27me3) to regulate gene expression through epigenetic machinery. In addition, EZH2 also functions both as a transcriptional suppressor and a...
