  Design, Synthesis, and Structure–Activity Relationships of Pyridoquinazolinecarboxamides as RNA Polymerase I Inhibitors

  摘要：

  RNA polymerase I (Pol I) is a dedicated polymerase that transcribes the 45S ribosomal (r) RNA precursor. The 45S rRNA precursor is subsequently processed into the mature 5.8S, 18S, and 28S rRNAs and assembled into ribosomes in the nucleolus. Pol I activity is commonly deregulated in human cancers. On the basis of the discovery of lead molecule BMH-21, a series of pyridoquinazolinecarboxamides have been evaluated as inhibitors of Pol I and activators of the destruction of RPA194, the Poll large catalytic subunit protein. Structure-activity relationships in assays of nucleolar stress and cell viability demonstrate key pharmacophores and their physicochemical properties required for potent activation of Pol I stress and cytotoxidty. This work identifies a set of bioactive compounds that potently cause RPA194 degradation that function in a tightly constrained chemical space. This work has yielded novel derivatives that contribute to the development of Pol I inhibitory cancer therapeutic strategies.

  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.

  RNA聚合酶I（Pol I）是专门用于转录47S核糖体RNA前体的聚合酶，随后将其加工成成熟的5.8S、18S和28S核糖体RNA，并在核仁中组装成核糖体。Pol I活性在人类癌症中常常失调。基于引物分子BMH-21的发现，合成了一系列吡啶喹唑啉羧酰胺作为Pol I的抑制剂和RPA194的破坏激活剂，RPA194是Pol I的大催化亚基蛋白。本发明确定了一组生物活性化合物，包括纯化的立体异构体，它们能够有效地导致RPA194的降解，这些化合物在一个严格受限制的化学空间中发挥作用。还提供了包括这些化合物的药物组合物及其在癌症和其他与Pol I相关疾病中的用途。
