生物活性

製品説明 CP-91149は、選択的グリコーゲンホスホリラーゼ(GP)阻害剤であり、グルコース存在下でのIC50は0.13 μMです。グルコース非存在下では、5〜10倍効力が低下します。
in vitro

CP-91149 displays 200-fold higher inhibitory activity against human liver glycogen phosphorylase a (HLGPa) than caffeine (IC50 = 26 μM). This compound (10-100 μM) inhibits -stimulated glycogenolysis in isolated rat hepatocytes in a dose-dependent manner, and in primary human hepatocytes with IC50 of ~2.1 μM. It also potently inhibits the activities of human muscle phosphorylase a and b with IC50 of 0.2 μM and ~0.3 μM, respectively. Treatment with this chemical at 2.5 μM induces inactivation of phosphorylase and sequential activation of glycogen synthase in hepatocytes, and increases glycogen synthesis by 7-fold at 5 mM glucose and by 2-fold at 20 mM glucose. It can partially counteract the effects of phosphorylase overexpression. This compound also potently inhibits brain GP with IC50 of 0.5 μM in A549 cells. Treatment at 10-30 μM causes significant glycogen accumulation in A549 and HSF55 cells. It treatment increases G1-phase cells with a significant reduction of the S-phase population in HSF55 cells, correlated with increased expression of p21 and p27. This chemical also promotes the dephosphorylation and activation of GS (glycogen synthase) in non-engineered or GP-overexpressing cultured human muscle cells, but exclusively in glucose-deprived cells.

in vivo

Oral administration of CP-91149 to diabetic ob/ob mice at 25-50 mg/kg causes rapid (3 hours) glucose lowering by 100-120 mg/dl without producing hypoglycemia, resulting from inhibition of glycogenolysis in vivo. This compound treatment does not lower glucose levels in normoglycemic, nondiabetic mice. In the non-fasted Goto-Kakizaki (GK) rats, administration of this chemical in combination with CS-917 suppresses hepatic glycogen reduction by CS-917 and decreases plasma glucose more than single administration of CS-917.

プロトコル(参考用のみ)

キナーゼアッセイ Phosphorylase enzyme assay
Human liver glycogen phosphorylase a (HLGPa, 85 ng) activity is measured in the direction of glycogen synthesis by the release of phosphate from glucose-1-phosphate at 22°C in 100 μL of buffer containing 50 mM Hepes (pH 7.2), 100 mM KCl, 2.5 mM EGTA, 2.5 mM MgCl2, 0.5 mM glucose-1-phosphate, and 1 mg/mL glycogen. Phosphate is measured at 620 nm, 20 minutes after the addition of 150 μL of 1 M HCl containing 10 mg/mL ammonium molybdate and 0.38 mg/mL malachite green. Increasing concentrations of this compound are added to the assay in 5 μL of 14% DMSO.
細胞アッセイ 細胞株 HSF55 and T98G
濃度 Dissolved in DMSO, final concentrations ~50 μM
反応時間 72 hours
実験の流れ

Cells are exposed to various concentrations of CP-91149 for 72hours. Viability is determined with manual cell counts following staining with trypan blue exclusion assay. Cells are fixed with 70% ethanol. DNA is stained with propidium iodide and the intensity of fluorescence is measured using a Becton-Dickinson flow cytometer at 488nm for excitation and at 650nm for emission. The cell cycle profile is analyzed using Modifit's Sync Wizard.
