  • Publication number: 20180362574
    Abstract: The present invention provides compounds of Formula (I) or (II), which are thought to be able to inhibit mTOR (mammalian target of rapamycin) signaling pathway, induce UPR (unfolded protein response), and/or perturb mitochondrial function of a cyst cell (e.g., a cyst cell causing polycystic kidney disease (PKD, e.g., autosomal dominant PKD (ADPKD) or autosomal recessive PKD (ARPKD)) or polycystic liver disease (PLD, e.g., autosomal dominant PLD (ADPLD) or autosomal recessive PLD (ARPLD)). The invention also provides pharmaceutical compositions, kits, and methods involving the compounds described herein for use in treating PKD or PLD, inhibiting the growth of a cyst cell, and/or killing a cyst cell.

  • Publication number: 20090062236
    Abstract: The compositions and methods disclosed herein provide heterobifunctional programmable genotoxic compounds that can be designed to kill selected cells present in a heterogenous cell population. The present compounds comprise a first agent that inflicts damage on cellular DNA, and a second agent that attracts a macromolecular cell component such as a protein, which in turn shields genomic lesions from repair. Unrepaired lesions therefore persist in the cellular genome and contribute to the death of selected cells. In contrast, lesions formed in nonselected cells, which lack the cell component, are unshielded and thus are repaired. As a result, compounds described herein are less toxic to nonselected cells. Compounds of this invention can be designed to cause the selective killing of transformed cells, viral-infected cells and the like.
