PFK-158

PFK-158 is a potent and selective PFKFB3 inhibitor with an IC₅₀ value 137 nM. PFK-158 reduces glucose uptake, ATP production, lactate release, and induces apoptosis and autophagy in cancer cells. PFK-158 has broad anti-tumor activity. PFK-158 can also enhance Colistin's resistance to bacteria^[1][2][3]. IC50 & Target: IC50 : 137 nM (PFKFB3)^[1][3] In Vitro: PFK-158 (10 µM ; 24 hours; OV2008 and C13 cells) combined with Carboplatin (CBPt; 77-453 μM) results in significant increase in apoptosis in C13 (45%) and OV2008 cells (24.6%)^[1].
PFK-158 (0-10 µM ; 24 hours; C13 and HeyA8MDR cells) treatment results in a dose-dependent decrease in p-PFKFB3, p-cPLA2 and lipid droplet (LD) levels^[1].
PFK-158 (10 μM; 24 hours) has synergistic anti-proliferative effects in vitro when combined with Cisplatin in C13 and HeyA8MDR cells compared to OV2008 and HeyA8, respectively^[1].
PFK-158 (0‐10 μM; 24 h) treatment shows a dose-dependent downregulation of p62/SQSTM1 and upregulation of LC3BII, two markers of autophagy induction, in both C13 and HeyA8MDR cells. PFK-158 treatment also reduces the numbers of LDs^[1]. In Vivo: PFK-158 (15 mg/kg; intraperitoneal injection; once a week; for 4 weeks; female athymic nude mice) plus CBPt (51 mg/kg) treatment leads to significantly enhanced antitumor activity in a gynecologic cancer mouse model^[1].
