Biochem/physiol Actions

DASA-58 is a potent and selective activator of cancer-specific pyruvate kinase isoform PKM2 (hPKM2 AC50 = 38 nM, Emax = 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).

The pyruvate kinase M2 (PKM2)-mediated aerobic glycolysis has been shown to play a critical role in promoting cell survival and proliferation. However, little is known about the function of intestinal epithelial PKM2 in intestine homeostasis. Here we investigate whether and
