GRP78-IN-4

GRP78-IN-4 is a GRP78 inhibitor with an IC₅₀ value of 1.1 μM. GRP78-IN-4 induces the unfolded protein response through the PERK/eIF2α/ATF4/CHOP and IRE1/XBP1s signaling pathways. GRP78-IN-4 exhibits cytotoxicity in cancer cell lines. GRP78-IN-4 can be used for research on lung cancer.

In Vitro

GRP78-IN-4 (Compound 12) (72 h) selectively kills A549 lung cancer cells with a CC₅₀ of 3.2 μM^[1].
GRP78-IN-4 has an IC₅₀ of 0.6 μM for GRP78 SBD and 1.2 μM for GRP78 FL^[1].
GRP78-IN-4 (0-16 μM) activates the PERK and IRE1 branches of the unfolded protein response (UPR) in A549 cells, increases the phosphorylation level of eIF2α, and upregulates the expression of ATF4 and CHOP as well as the XBP1 splicing product XBP1s^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
