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.
本发明包括有用于抑制IRE1/XBP-1途径的取代香豆素。在某些实施方式中,本发明的化合物抑制IRE1的RNase活性。在其他实施方式中,本发明的化合物用于治疗或预防涉及ER应激反应激活的癌症。本发明还涉及在某些方面的发现,即分泌型IgM(sIgM)可以通过将髓样来源的抑制细胞(MDSCs)招募到不同的肿瘤模型中,如但不限于固体肿瘤(如肺癌)和具有高水平分泌IgM的肿瘤。在某些实施方式中,由B细胞或CLL细胞产生的sIgM可以促进肿瘤中MDSCs的积累。在其他实施方式中,抑制IRE1/XBP-1途径可以消除、最小化或减少肿瘤中的MDSC水平。
