Overview

First-in-class MTHFD2 inhibitor, impairing cancer progression in vivo, preventing thymidine production leading to misincorporation of uracil into DNA and replication stress

Mechanism & Target Enzymes

  • TH7299 inhibits MTHFD2 (mitochondrial methylenetetrahydrofolate dehydrogenase 2), but it is not very selective: it also inhibits MTHFD2L (an isoform) and MTHFD1. 

  • Some reported potencies:

    EnzymeIC₅₀ for TH7299
    MTHFD2~ 254 nM PMC+2probechem.com+2
    MTHFD1~ 89 nM PMC+2probechem.com+2
    MTHFD2L~ 126 nM PMC+2probechem.com+2

  • Binding mode: TH7299 binds in the folate binding site of MTHFD2 / MTHFD2L. The structure of human MTHFD2L in complex with TH7299 has been solved (PDB 7QEI). Chemistry Europe+2RCSB PDB+2

  • Key interactions include hydrogen bonds between the diaminopyrimidine head group and residues like Asp169, Val145 / Leu147; interactions via the urea linker with Asn101, Lys102, Gln146; pi-stacking with Tyr98; the glutamate tail interacting with Gly324 and Tyr292; plus hydrophobic contacts. Chemistry Europe

Biological Effects & Potential Uses

  • In cellular assays (acute myeloid leukemia cells in vitro & in vivo), TH7299 (along with related inhibitors) causes:

    1. Reduced replication fork speed

    2. Replication stress

    3. S-phase cell cycle arrest

    4. Apoptosis (cell death) in some settings. PMC

  • It also leads to disruption of thymidine production, causing uracil misincorporation into DNA. These are hallmarks of perturbing folate-1C metabolism. PMC+1

  • As of now, TH7299 is for research use only; it is preclinical (not approved for human or veterinary use). 

Strengths & Limitations

Strengths:

  • Nanomolar potency against multiple folate pathway enzymes → can be useful as a tool compound for studying those pathways. PMC

  • Crystallographic data available → structure-guided drug design possible. RCSB PDB+1

Limitations:

  • Lack of high isoform selectivity: TH7299 also inhibits MTHFD1 and MTHFD2L, which may lead to off-target effects or toxicity in settings where those isoforms are essential. PMC+1

  • Lead times / supply may be long for some vendors; stock is sometimes unavailable.
