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.

The present invention relates to a method of treatment and method of therapy selection for patient suffering from cancer. The inventors provide the first demonstration of a dual role of IRE1 downstream signaling in cancer. Indeed, the inventors demonstrate that the modulation of IRE1 signaling characteristics in GBM cells controls tumor aggressiveness. Furthermore, the inventors provide evidence supporting a novel concept where IRE-downstream signals play combined/integrated roles in cancer development, where XBP1s provides pro-tumoral signals, whereas RIDD of mRNA and miR17 rather elicits anti-tumoral features. Their data, obtained using established cell lines, patient tumor samples and primary GBM lines, depict a complex scenario where IRE1 signaling orchestrates distinct aspects of GBM biology. In particular, the invention relates to a method for predicting whether a subject will be eligible to a treatment with an IRE1 RNase inhibitor.
