  Synthesis of Novel Tricyclic Chromenone-Based Inhibitors of IRE-1 RNase Activity

  摘要：

  Inositol-requiring enzyme 1 (IRE-1) is a kinase/RNase ER stress sensor that is activated in response to excessive accumulation of unfolded proteins, hypoxic conditions, calcium imbalance, and other stress stimuli. Activation of IRE-1 RNase function exerts a cytoprotective effect and has been implicated in the progression of cancer via increased expression of the transcription factor XBP-1s. Here, we describe the synthesis and biological evaluation of novel chromenone-based covalent inhibitors of IRE-1. Preparation of a family of 8-formyltetrahydrochromeno[3,4-c]pyridines was achieved via a Duff formylation that is attended by an unusual cyclization reaction. Biological evaluation in vitro and in whole cells led to the identification of 30 as a potent inhibitor of IRE-1 RNase activity and XBP-1s expression in wild type B cells and human mantle cell lymphoma cell lines.

  The present invention includes substituted chromenones that are useful to inhibit the IRE1/XBP-1 pathway. In certain embodiments, the compounds of the invention inhibit IRE1s RNase activity. In other embodiments, the compounds of the invention are useful to treat or prevent a cancer that involve activation of the ER stress response. The invention also relates, in certain aspects, to the discovery that secretory IgM (sIgM) can orchestrate an immunosuppressive microenvironment by recruiting myeloid-derived suppressor cells (MDSCs) into different tumor models, such as but not limited to solid tumors (such as lung cancer) and tumors that have high levels of secreted IgM. In certain embodiments, sIgM produced by B cells or CLL cells can contribute to the accumulation of MDSCs in a tumor. In other embodiments, inhibition of the IRE1/XBP-1 pathway can ablate, minimize, or reduce MDSC levels in a tumor.

  Disclosed are XBP-1/IRE-1 inhibitors having formula disclosed herein. Methods of making and using these inhibitors for the treatment of cancer, in particular B cell cancers, are also disclosed. Also disclosed is a genetic XBP-1-knockout cancer mouse model. In still further aspects, the disclosed subject matter relates to methods for treating oncological and inflammatory disorders in a patient. For example, disclosed herein are methods whereby an effective amount of a compound or composition disclosed herein is administered to a patient having an oncological disorder, for example B-cell chronic lymphocytic leukemia (CLL), and who is in need of treatment thereof. XBP-1 deficiency causes leukemic cells to acquire phenotypes that are disadvantageous for their survival, such as compromised BCR signaling capability and increased surface expression of S1 P1.

  Activation of the IRE-1/XBP-1 pathway has been linked to many human diseases. We report a novel fluorescent tricyclic chromenone inhibitor, D-F07, in which we incorporated a 9-methoxy group onto the chromenone core to enhance its potency and masked the aldehyde to achieve long-term efficacy. Protection of the aldehyde as a 1,3-dioxane acetal led to strong fluorescence emitted by the coumarin chromophore, enabling D-F07 to be tracked inside the cell. We installed a photolabile structural cage on the hydroxy group of D-F07 to generate PC-D-F07. Such a modification significantly stabilized the 1,3-dioxane acetal protecting group, allowing for specific stimulus-mediated control of inhibitory activity. Upon photoactivation, the re-exposed hydroxy group on D-F07 triggered the aldehyde-protecting 1,3-dioxane acetal to slowly decompose, leading to the inhibition of the RNase activity of IRE-1. Our novel findings will also allow for spatiotemporal control of the inhibitory effect of other salicylaldehyde-based compounds currently in development.
