SCR1693
SCR1693 is a selective, reversible, orally active and noncompetitive inhibitor of AChE (IC50 = 0.68 μM) as well as a calcium channel blocker. SCR1693 reduces tau phosphorylation levels, and inhibits the generation and release of Aβ. SCR1693 restores insulin signaling and improves cognitive deficits. SCR1693 can be used for the study of Alzheimer's disease, especially which complicated with type 2 diabetes mellitus.

AChE |
SCR1693 (0.4-5 μM, 24 h) reduces total and phosphorylated tau levels in HEK293/tau cells[1].
SCR1693 (0.8-20 μM, 6 h) induces tau dephosphorylation and increases total tau levels in HEK293/tau cells with short-term treatment[1].
SCR1693 (0.4-4 μM, 24 h) inhibits Aβ generation and release in N2a/APP cells[1].
SCR-1693 (3.3-30 μM, 6 h) downregulates tau phosphorylation mainly by regulating its phosphatases in Neuro-2a-tau cells[2].
SCR-1693 (10 μM , 6 h) activates PKA/Akt, inhibits GSK-3β, and enhances PP2A/PP1 activity in Neuro-2a-tau cells[2].
SCR-1693 (10 μM, 6 h) reduces insulin resistance by regulating PP1/PP2A in Neuro-2a-tau cells[2].
SCR-1693 (0.004-2.5 μM, 48 h) inhibits Aβ25-35 (HY-P0128)-induced SH-SY5Y cell death[3].

-
Cell Line:HEK293/tau cells
-
Concentration:0.4, 2, 5 μM
-
Incubation Time:24 h
-
Result:Increased tau dephosphorylation level at Ser198/199/202 sites (Tau 1 epitope) concentration dependently.
Reduced total tau level significantly at 5 μM.
-
Cell Line:HEK293/tau cells
-
Concentration:0.8, 4, 20 μM
-
Incubation Time:6 h
-
Result:Induced tau dephosphorylation at Ser198/199/202 (Tau-1) sites and increased total tau level (4 μM and 20 μM).
-
Cell Line:Neuro-2a-tau cells
-
Concentration:3.3, 10, 30 μM
-
Incubation Time:6 h
-
Result:Decreased tau phosphorylation levels at the sites of Ser199/202, Ser202/T205, T212/Ser214, Thr231, Ser262 and Ser356, rather than Ser422,and increased tau dephosphorylation level.
Activated PKA and Akt, and inhibited GSK-3β activation.
Decreased the negatively regulated phosphorylation of PP2AC and PP1 at the site of Tyr307 and Thr320, respectively.
Enhanced PP2A and PP1 activity.
Enlarged insulin signaling, especially p-IRS-1 Tyr632 and p-Akt Ser473.
SCR1693 (3-30 mg/kg, p.o. single dose) dose-dependently causes the inhibition of brain homogenate AChE activity in wistar rats[3].
SCR1693 (0.1-1 mg/kg, p.o., once daily, 12 days) improves spatial memory in Aβ25-35-treated mice [3].

-
Animal Model:STZ (3 mg/kg) was administered intracerebroventricularly twice in male wistar rats (220-250 g)[2]
-
Dosage:1, 2, 4 mg/kg
-
Administration:i.g., once daily for 20 days
-

Decreased AChE activity.
Prevented Aβ25-35-induced loss of hippocampal pyramidal cells.
Protected hippocampal synaptic transmission and LTP.
Regulated hippocampal protein phosphorylation in Aβ25–35-treated mice.
