  • Patent number: 11001581
    Abstract: RNA polymerase I (Pol I) is a dedicated polymerase for the transcription of the 47S ribosomal RNA precursor subsequently processed into the mature 5.8S, 18S and 28S ribosomal RNAs and assembled into ribosomes in the nucleolus. Pol I activity is commonly deregulated in human cancers. Based on the discovery of lead molecule BMH-21, a series of pyridoquinazolinecarboxamides were synthesized as inhibitors of Pol I and activators of the destruction of RPA194, the Pol I large catalytic subunit protein. The present invention identifies a set of bioactive compounds, including purified stereoisomers, that potently cause RPA194 degradation that function in a tightly constrained chemical space. Pharmaceutical compositions comprising these compounds and their uses in cancer and other Pol I related diseases is also provided.

  • Patent number: 10994015
    Abstract: The present disclosure relates to bifunctional compounds, which find utility as modulators of receptor tyrosine kinase (RTK) proteins. In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a ligand which binds to an E3 ubiquitin ligase and on the other end a moiety which binds a target protein, such that the target protein is placed in proximity to the ubiquitin ligase to effectuate ubiquitination, and therefore, degradation (and inhibition) of the target protein. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of target protein. Diseases or disorders that result from aggregation or accumulation of the target protein are treated or prevented with compounds and compositions of the present disclosure.
