JR4-187

JR4-187 is an orally active, copper-dependent anticancer agent. JR4-187 downregulates genes involved in oxidative phosphorylation, MYC targets and E2F targets in cancer cells, while upregulates genes involved in the TNF-α signaling pathway, p53 pathway and KRAS signaling pathway, and downregulates CTR1 protein. JR4-187 induces ROS production, apoptosis, copper-dependent cytotoxicity, and exhibits selective cytotoxicity against KRAS-mutant cancer cells. JR4-187 is well tolerated in mouse models of pancreatic cancer. JR4-187 can be used in research related to cancers such as pancreatic ductal adenocarcinoma, colon cancer and rectal cancer.

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.
