  • PubMed Abstract: 

    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.
