설명

일반 설명

A cell-permeable thienopyrrolopyridazinone that acts as a potent allosteric PKM2 activator (AC₅₀ = 92 nM; [PKM2] = 0.1 nM) via stoichiometric interaction (Two activator molecules per tetramer) with FBP-bound PKM2 tetramer (One FBP per monomer) in a similar manner as PKM2 Activator III (Cat. No. 504537), resulting in highly stabilized PKM2 tetramer resistant to dissociation in the presence of phosphotyrosine-containing peptide/protein or upon PKM2 K305Q mutation. Reported to exhibit good aqueous solubility (29.6 µg/mL or 79.5 µM in PBS, pH 7.4) and retard human lung carcinoma H1299 proliferation under hypoxia, but not normoxia, condition in cultures (doubling time = 50 and 35 h, respectively, with or without 30 µM TEPP-46; 1% O₂) in vitro. TEPP-46 is bioavailable in mice via i.p. (T_max = 0.5 h; C_max = 10.854 µg/mL; AUC_INF = 26.994 hr·µg/mL; 10 mg/kg) or p.o. (T_max = 0.25 h; C_max = 10.179 µg/mL; AUC_INF = 24.350 hr·µg/mL; 10 mg/kg) administration and shown to impair H1299 tumorigenesis in mice (%tumor development/av. tumor weight = 30%/0.13 mg and 70%/2.6 mg, respectively, with or without 50 mg/kg/12 h oral dosage for 7 wks) in vivo with no apparent toxicity.
