  Structure-Based Design of Orally Bioavailable 1H-Pyrrolo[3,2-c]pyridine Inhibitors of Mitotic Kinase Monopolar Spindle 1 (MPS1)

  摘要：

  The protein kinase MPS1 is a crucial component of the spindle assembly checkpoint signal and is aberrantly over-expressed in many human cancers. MPS1 is one of the top 25 genes overexpressed in tumors with chromosomal instability and aneuploidy. PTEN-deficient breast tumor cells are particularly dependent upon MPS1 for their survival, making it a target of significant interest in oncology. We report the discovery and optimization of potent and selective MPS1 inhibitors based on the 1H-pyrrolo[3,2-c]pyridine scaffold, guided by structure-based design and cellular characterization of MPS1 inhibition, leading to 65 (CCT251455). This potent and selective chemical tool stabilizes an inactive conformation of MPS1 with the activation loop ordered in a manner incompatible with ATP and substrate-peptide binding; it displays a favorable oral pharmacokinetic profile, shows dose-dependent inhibition of MPS1 in an HCT116 human tumor xenograft model, and is an attractive tool compound to elucidate further the therapeutic potential of MPS1 inhibition.

  An unprecedented deconstructive reorganization strategy for the de novo synthesis of hydroxylated benzofurans from kojic acid- or maltol-derived alkynes is reported. In this reaction, both the benzene and furan rings were simultaneously constructed, whereas the pyrone moiety of the kojic acid or maltol was deconstructed and then reorganized into the benzene ring as a six-carbon component. Through this

  报道了一种空前的解构重组策略，用于从曲酸或麦芽酚衍生的炔烃从头合成羟基化苯并呋喃。在该反应中，同时构造了苯环和呋喃环，而曲酸或麦芽酚的吡喃酮部分被解构，然后以六碳组分重组为苯环。通过这种策略，以取代模式可调节的方式将至少一个游离羟基引入苯环，而无需进行保护-脱保护和氧化还原调节。通过这种方法，已经有效地制备了具有不同取代模式的大量羟基化苯并呋喃衍生物。
