CP-91149 is a GP (glycogen phosphorylase) inhibitor. CP-91149 promotes glycogen resynthesis, but not its overaccumulation. CP-91149 has the potential for Type II (insulin-dependent) diabetes study.

体外研究(In Vitro)
CP-91149 treatment decreases muscle GP activity by converting the phosphorylated AMP-independent α form into the dephosphorylated AMP-dependent b form and inhibiting GP α activity and AMP-mediated GP b activation.
CP-91149 (10, 30, 50 μM) inhibits brain GP and causes glycogen accumulation in A549 cells.
Medlife has not independently confirmed the accuracy of these methods. They are for reference only.
Cell Viability Assay
Cell Line:
Cells were transduced with adenoviruses and incubated in the presence of 25 mM glucose for 2 days.
Concentration:
10 μM (glucose? or glucose+ for 18 h).
Incubation Time:
3 h.
Result:
Promoted the conversion of GP a into GP b, according to α model proposed in hepatocytes.
Western Blot Analysis
Cell Line:
A549 cells.
Concentration:
0, 10, 30, 50 μM.
Incubation Time:
72 h.
Result:
A significant increase in glycogen accumulation was detected at 10 μM of CP-91149 as compared with untreated cells with a maximal glycogen accumulation at 30 μM. Intracellular glycogen content decreased at 50 μM CP-91149, perhaps explained by additional pharmacological effects of the drug. The dose-dependent accumulation of intracellular glycogen in A549 cells by CP-91149 indicates that CP-91149 inhibits brain GP in tissue culture.
