  Inhibition of Cancer-Associated Mutant Isocitrate Dehydrogenases by 2-Thiohydantoin Compounds

  摘要：

  Somatic mutations of isocitrate dehydrogenase 1 (LDH1) at R132 are frequently found in certain cancers such as glioma. With losing the activity of wild-type IDH1, the R132H and R132C mutant proteins can reduce alpha-ketoglutaric acid (alpha-KG) to D-2-hydroxyglutaric acid (D2HG). The resulting high concentration of D2HG inhibits many alpha-KG-dependent dioxygenases, including histone demethylases, to cause broad histone hypermethylation. These aberrant epigenetic changes are responsible for the initiation of these cancers. We report the synthesis, structure activity relationships, enzyme kinetics, and binding thermodynamics of a novel series of 2-thiohydantoin and related compounds, among which several compounds are potent inhibitors of mutant IDH1 with K-i as low as 420 nM. X-ray crystal structures of IDH1(R132H) in complex with two inhibitors are reported, showing their inhibitor-protein interactions. These compounds can decrease the cellular concentration of D2HG, reduce the levels of histone methylation, and suppress the proliferation of stem-like cancer cells in BT142 glioma with IDH1 R132H mutation.

  Previously we reported the discovery of CRA-898 (1), a diazine indole acetic acid containing CRTH2 antagonist. This compound had good in vitro and in vivo potency, low rates of metabolism, moderate permeability, and good oral bioavailability in rodents. However, it showed low oral exposure in nonrodent safety species (dogs and monkeys). In the current paper, we wish to report our efforts to understand and improve the poor PK in nonrodents and development of a new isoquinolinone subseries that led to identification of a new development candidate, CRA-680 (44). This compound was efficacious in both a house dust mouse model of allergic lung inflammation (40 mg/kg qd) as well as a guinea pig allergen challenge model of lung inflammation (20 mg/kg bid).
