What is 7-AMINO-4-CHLORO-3-METHOXYISOCOUMARIN?

The Uses of 7-AMINO-4-CHLORO-3-METHOXYISOCOUMARIN

JLK 6 is an inhibitor of γ-secretase, selectively inhibits βAPP cleavage.

Definition

ChEBI: 7-amino-4-chloro-3-methoxy-2-benzopyran-1-one is a member of isocoumarins.

Biological Activity

Inhibitor of γ -secretase that selectively inhibits β APP cleavage without affecting other γ -secretase-mediated pathways. Prevents recovery of A β 40 and A β 42 from HEK293 cell overexpressing wild-type or Swedish-mutated β APP (IC 50 ~ 30 μ M) but displays no effect on Notch cleavage and Notch-mediated intracellular signaling. Displays no activity on BACE1, BACE2, α -secretase, the proteosome or GSK3 β .
