Disease

IDHC_HUMAN Defects in IDH1 are involved in the development of glioma (GLM) [MIM:137800. Gliomas are central nervous system neoplasms derived from glial cells and comprise astrocytomas, glioblastoma multiforme, oligodendrogliomas, and ependymomas. Note=Mutations affecting Arg-132 are tissue-specific, and suggest that this residue plays a unique role in the development of high-grade gliomas. Mutations of Arg-132 to Cys, His, Leu or Ser abolish magnesium binding and abolish the conversion of isocitrate to alpha-ketoglutarate. Instead, alpha-ketoglutarate is converted to R(-)-2-hydroxyglutarate. Elevated levels of R(-)-2-hydroxyglutarate are correlated with an elevated risk of malignant brain tumors.

Publication Abstract from PubMed

Inhibition of mutant IDH1 is being evaluated clinically as a treatment option for oncology. Here we describe the structure-based design and optimization of quinoline lead compounds to identify FT-2102, a potent, orally bioavailable, brain penetrant, and selective mIDH1 inhibitor. FT-2102 has excellent ADME/PK properties and reduces 2-hydroxyglutarate levels in an mIDH1 xenograft tumor model. This compound has been selected as a candidate for clinical development in hematologic malignancies, solid tumors, and gliomas with mIDH1.
