DASA-58 is a potent and selective activator of cancer-specific pyruvate kinase isoform PKM2 (hPKM2 AC50 = 38 nM, E_max = 82%), but not PKM1, PKR or PKL, that stabilizes PKM2 tetrameric conformation by targeting a site distinct from that of fructose-1,6-bis-phosphate (FBP). DASA-58 exhibits good aqueous solubility (51.2 μg/mL), decreases cellular lactate production and suppresses cell proliferation selectively under hypoxic conditions (30 μM; H1299, 1% O2). When administered in mice, DASA-58 is reported to exhibit anti-thrombotic efficacy in vivo (40 mg/kg via iv).
