MTX-531 is an orally active small molecule that inhibits EGFR (IC50 = 14.7 nM) and multiple PI3K isoforms, with IC50 values of 6.4 nM (PI3Kα), 233 nM (PI3Kβ), 8.3 nM (PI3Kγ), and 1.1 nM (PI3Kδ), demonstrating potent antitumor activity. Additionally, MTX-531 functions as a weak PPARγ agonist (IC50 = 2.5 µM), which may mitigate PI3K inhibitor-induced hyperglycemia.
