KYP 2047

KYP-2047 is a potent and BBB-penetrating prolyl-oligopeptidase (POP) inhibitor, with an Ki value of 0.023 nM. KYP-2047 reduces glioblastoma proliferation through angiogenesis and apoptosis modulation[1][2].

KYP-2047 (0-100 μM) decreases U-87, U-138 and A-172 cell viability in a concentration-dependent manner[2]. KYP-2047 (0-100 μM) increases the pro-apoptotic protein Bax, p53 and caspase-3 expression whereas reduces Bcl-2 expression, and reduced significantly TGF-β expression[2]. Cell Proliferation Assay Cell Line: U-87, U-138 and A-172 cell[2] Concentration: 0.01 μM, 0.1 μM, 0.5 μM, 1 μM, 10 μM, 30 μM, 50 μM and 100 μM Incubation Time: 24 h Result: Decreased U-87, U-138 and A-172 cell viability in a concentration-dependent manner. Western Blot Analysis Cell Line: U-87 cell[2] Concentration: 0, 50, 100 μM Incubation Time: 24 h Result: Increased the pro-apoptotic protein Bax, p53 and cleaved-caspase-3 expression, reduced significantly Bcl2 expression, reduced Ang1 and Ang2 expression, and decreased Ki-67 expression.

KYP-2047 (1 or 5 mg/kg, 30 min before daily testing) dose-dependently improved the escape performance (i.e. latency to find the hidden platform and swimming path length) of the young but not the old rats in the water maze[1]. KYP-2047 (9 or 27 μmol/kg; IP; once, 1 or 3 h before decapitation; two daily doses for 10 days) increases neurotensin concentration in the hypothalamus[1]. KYP-2047 (0-5 mg/kg) significantly reduces tumor mass and neutrophil infiltration[2]. KYP-2047 (0-5 mg/kg) significantly reduces vascular endothelial-growth-factor (VEGF), CD34, angiopoietins (Ang) and endothelial-nitric-oxide synthase (eNOS) expression[2].
