Biochem/physiol Actions

LY345899 (LY354899) is a methylenetetrahydrofolate dehydrogenase inhibitor (MTHFD1 IC50 = 96 nM with 30 μM folitixorin and 400 μM NADP+; MTHFD2 IC50 = 663 nM with 5 μM folitixorin and 250 μM NAD+) that exerts antiproliferation activity against cancer cells by targeting the folate cycle. Co-administer LY345899 with the dihydrofolate reductase (DHFR) inhibitor methotrexate (MTX) overcomes AML MTX resistance (50 mg/kg) in mice in vivo (10 mg/kg q.o.d. i.p.).

Metabolic reprogramming by oncogenic signaling is a hallmark of cancer. Hyperactivation of Wnt/β-catenin signaling has been reported in hepatocellular carcinoma (HCC). However, the mechanisms inducing hyperactivation of Wnt/β-catenin signaling and strategies for targeting this pathway are incompletely understood. In this

5,6,7,8-Tetrahydro-N5,N10-carbonylfolic acid (LY354899) has been demonstrated to inhibit the dehydrogenase activity of C1-tetrahydrofolate synthase. This compound was only moderately antiproliferative toward CCRF-CEM lymphocytic leukemia cells in culture, but induced apoptosis after long incubation times. Slightly greater potency was observed in

The folate metabolism enzyme MTHFD2 (methylenetetrahydrofolate dehydrogenase/cyclohydrolase) is consistently overexpressed in cancer but its roles are not fully characterized, and current candidate inhibitors have limited potency for clinical development. In the present study, we demonstrate a role for MTHFD2 in
Josep Tarragó-Celada et al.
Cancers, 13(3) (2021-01-28)
With most cancer-related deaths resulting from metastasis, the development of new therapeutic approaches against metastatic colorectal cancer (mCRC) is essential to increasing patient survival. The metabolic adaptations that support mCRC remain undefined and their elucidation is crucial to identify potential
