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).
Potent and selective activator of cancer-specific pyruvate kinase PKM2 in vitro and in vivo, but not PKM1, PKR or PKL.
Nonalcoholic steatohepatitis (NASH) is the most prevalent cause of chronic liver disease worldwide. Macrophage-mediated inflammation plays a critical role in NASH pathogenesis; however, optimum therapies for macrophage activation and NASH remain elusive. HSPA12A encodes a novel member of the HSP70

The metabolism of cancer cells is altered to support rapid proliferation. Pharmacological activators of a tumor cell specific pyruvate kinase isozyme (PKM2) may be an approach for altering the classic Warburg effect characteristic of aberrant metabolism in cancer cells yielding

Chaetocin is a fungal metabolite that possesses a potential anti-inflammatory activity. Acute gout is a self-limiting inflammatory response to monosodium urate (MSU) crystals. However, the effect of cheatocin on gout has not been elucidated. In the study, we found that
Antibody affinity maturation occurs in germinal centers (GCs), where B cells cycle between the light zone (LZ) and the dark zone. In the LZ, GC B cells bearing immunoglobulins with the highest affinity for antigen receive positive selection signals from

Reactive oxygen species (ROS) can act as second messengers in various signaling pathways, and abnormal oxidation contributes to multiple diseases, including cancer. Detecting and quantifying protein oxidation is crucial for a detailed understanding of reduction-oxidation reaction (redox) signaling. We developed
