Methotrexate Analogs with Enhanced Efficacy and Safety Profile
Scientists at NCATS have developed an analog of Methotrexate (MTX) that incorporates the proteasome-targeting properties of E3-ubiquitin ligase small molecule ligands (MTX-PROTACs) to directly bind to the MTX target dihydrofolate reductase (DHFR) and mark the protein for proteasomal degradation. This unique property may dramatically lower the therapeutic dose required in a treatment setting.
