- Design, Synthesis, and Structure-Activity Relationship of Tetrahydropyrido[4,3-d]pyrimidine Derivatives as Potent Smoothened Antagonists with in Vivo Activity
-
Medulloblastoma is one of the most prevalent brain tumors in children. Aberrant hedgehog (Hh) pathway signaling is thought to be involved in the initiation and development of medulloblastoma. Vismodegib, the first FDA-approved cancer therapy based on inhibition of aberrant hedgehog signaling, targets smoothened (Smo), a G-protein coupled receptor (GPCR) central to the Hh pathway. Although vismodegib exhibits promising therapeutic efficacy in tumor treatment, concerns have been raised from its nonlinear pharmacokinetic (PK) profiles at high doses partly due to low aqueous solubility. Many patients experience adverse events such as muscle spasms and weight loss. In addition, drug resistance often arises among tumor cells during treatment with vismodegib. There is clearly an urgent need to explore novel Smo antagonists with improved potency and efficacy. Through a scaffold hopping strategy, we have identified a series of novel tetrahydropyrido[4,3-d]pyrimidine derivatives, which exhibited effective inhibition of Hh signaling. Among them, compound 24 is three times more potent than vismodegib in the NIH3T3-GRE-Luc reporter gene assay. Compound 24 has a lower melting point and much greater solubility compared with vismodegib, resulting in linear PK profiles when dosed orally at 10, 30, and 100 mg/kg in rats. Furthermore, compound 24 showed excellent PK profiles with a 72% oral bioavailability in beagle dogs. Compound 24 demonstrated overall favorable in vitro safety profiles with respect to CYP isoform and hERG inhibition. Finally, compound 24 led to significant regression of subcutaneous tumor generated by primary Ptch1-deficient medulloblastoma cells in SCID mouse. In conclusion, tetrahydropyrido[4,3-d]pyrimidine derivatives represent a novel set of Smo inhibitors that could potentially be utilized to treat medulloblastoma and other Hh pathway related malignancies.

- HEDGEHOG PATHWAY SIGNALING INHIBITORS AND THERAPEUTIC APPLICATIONS THEREOF
-
The hedgehog (Hh) signaling pathway is a pathway which regulates patterning, growth and cell migration during embryonic development, but in adulthood is limited to tissue maintenance and repair. Mutational inactivation of the inhibitory pathway components leads to constitutive ligand-independent activation of the Hh signaling pathway, results in cancers such as basal cell carcinoma and medulloblastoma. Ligand-dependent activation of Hh signaling is involved in prostate cancer, pancreatic cancer, breast cancer and blood cancers. Therefore, inhibition of the aberrant Hh signaling represents a promising approach toward novel anticancer therapy. The invention provides novel molecules of formula I that inhibit hedgehog pathway signaling and provides therapeutic applications for the treatment of malignancies (basal cell carcinoma, medulloblastoma, glioblastoma, non-small cell lung cancer, prostate cancer, pancreatic cancer, blood cancers, mesenchymal cancers, etc.), prevention of tumor regrowth, sensitization of radio-chemo therapies, and other diseases (inflammation, fibrosis and immune disorders).
