A Phase Ib Study of Fruquintinib in 3rd Line mCRC

ABSTRACT: Fruquintinib is a novel oral small molecule compound discovered and developed by Hutchison MediPharma that selectively inhibits vascular endothelial growth factor receptors (VEGFR) 1, 2, and 3 and has demonstrated potent inhibitory effects on multiple human tumor xenografts.Based on first-in-human study, both 4mg QD and 5mg 3wks on/1wk off are safety and efficacy, this phase Ib study is to evaluable the safety, tolerability and efficacy of these 2 regimens with mCRC failed 2nd therapy or more and to determine the recommended dose and regimen in phase II/III study.

Hepatic Arterial Infusion Chemotherapy With Fruquintinib for Colorectal Cancer Liver Metastases As Third-line Therapy

Project description:Fruquintinib (HMPL-013) is a novel oral small molecule that selectively inhibits vascular endothelial growth factor receptors (VEGFR) 1, 2, and 3 and has demonstrated potent inhibitory effects on multiple human tumor xenografts. Combined with hepatic arterial infusion chemotherapy (HAIC), this study is conducted to assess the efficacy and safety of this regimen in patients with unresectable colorectal cancer liver metastases as the third-line therapy.

EED226, an allosteric PRC2 inhibitor, modulates gene transcription in EZH2 mutant lymphoma cell Karpas422 through PRC2 inhibition

Project description:Polycomb repressive complex (PRC) 2, containing minimally EZH2, EED and Suz12, is the H3 lysine 27 methyltransferase playing pivotal roles in transcriptional regulation. EZH2 is the catalytic subunit, and H3K27me3 activates PRC2 through binding EED to propagate the repressive mark. Cofactor SAM-competitive (SAM-C) PRC2 inhibitors (PRC2is) have been discovered to treat lymphoma and rhabdoid tumors. Here we report the discovery of EED226, a potent and selective PRC2i directly binding to the H3K27me3 pocket of EED. Upon binding, EED226 induces conformational change in EED protein. Interestingly, it inhibits both the basal and the H3K27me3-stimulated PRC2 activities. Furthermore, EED226 selectively pulled down the endogenous PRC2 complex from human cell lysates, specifically modulates H3K27 methylation and target genes similarly as SAM-C PRC2 inhibitors, and effectively regresses human lymphoma xenograft tumor in mouse. More importantly, EED226 potently inhibits the SAM-C inhibitor-resistant PRC2 and synergizes with SAM-C PRC2i in cell proliferation blocking. Together, EED226 is an inhibitor of PRC2 with a novel mechanism and represent a potential complementary strategy for PRC2-targeted cancer therapy.

MManassantin A iTRAQ-SPROX Drug Mode-of-Action

Project description:Manassantin A is a natural product that has been isolated from the perennial herb Saururus chinensis Baill and the aquatic plant Saururus cernuus. Manassantin A has been shown to possess potent hypoxia inducible factor 1 alpha (HIF-1α) inhibitory activity in a cell-based assay screen of thousands of natural products. Manassantin A holds promise as an anti-cancer drug since it has been shown to selectively target tumor cells over normal cells. Due to the complex biological pathways involved in cancer and hypoxia, it is difficult to determine the mode-of-action by which manassantin A inhibits HIF-1. While some of the biological activities of manassantin A have been discovered in various cell-based activity assays, the molecular basis of manassantin A’s biological activities is not well characterized. The proteins in a hypoxic MDA-MB-231 cell lysate were screened for interactions with manassantin A using large scale experiments to uncover novel manassantin A interactions that lead to the drug’s HIF-1 inhibition and anti-cancer activity. Two energetics-based approaches were utilized in this manassantin A mode-of-action study: iTRAQ-SPROX and SILAC-Pulse Proteolysis. In these energetics-based approaches, protein stability is measured using the chemical denaturant dependence of either a methionine oxidation reaction (iTRAQ-SPROX) or a thermolysin protease digest (SILAC-Pulse Proteolysis). Using boh of these techniques, the stability of proteins in the absence and presence of excess manassantin A was monitored to assess ligand-induced protein stability changes.

Expression Profiling of Mixed Lineage Leukemia Cells Treated with a Potent Small-Molecule DOT1L Inhibitor

Project description:Cell lines bearing MLL translocations (MV4-11 and MOLM-13) were treated with a potent, selective inhibitor of the DOT1L histone methyl transferase. Treatment of MLL-rearranged cell lines with the DOT1L inhibitor selectively inhibits H3K79 methylation and blocks expression of leukemogenic genes. Here we provide expression profiling data of cells treated with DOT1L inhibitor or vehicle control.

Identification of biomarkers for tumor endothelial cell proliferation through gene expression profiling

Project description:Extensive efforts are underway to identify anti-angiogenic therapies for the treatment of human cancers. Many proposed therapeutics target vascular endothelial cell growth factor (VEGF) or the kinase insert domain receptor (KDR/VEGFR-2/FLK-1), the mitogenic VEGF receptor tyrosine kinase expressed by endothelial cells. Inhibition of KDR catalytic activity blocks tumor neo-angiogenesis, reduces vascular permeability, and, in animal models, inhibits tumor growth and metastasis. Using a gene expression profiling strategy in rat tumor models, we identified a set of six genes that are selectively overexpressed in tumor endothelial cells relative to tumor cells, and whose pattern of expression correlates with the rate of tumor endothelial cell proliferation. In addition to being potential targets for anti-angiogenesis tumor therapy, the expression patterns of these genes or their protein products may aid the development of pharmacodynamic assays for small molecule inhibitors of the KDR kinase in human tumors.
