QD-394 is an inducer of reactive oxygen species (ROS) production.1It induces lipid peroxidation, increases in intracellular accumulation of reactive oxygen species (ROS), and decreases in the reduced glutathione (GSH) to oxidized GSH (GSSG) ratio in MIA PaCa-2 pancreatic cancer cells when used at concentrations ranging from 0.5 to 10 μM. QD-394 is cytotoxic to MIA PaCa-2, PANC-1, and BxPC-3 cancer cells (IC50s = 0.64, 0.34, and 0.9 μM, respectively). QD-394 acts synergistically with napabucasin to reduce colony formation in MIA PaCa-2 cells. 1.Hu, S., Sechi, M., Singh, P.K., et al.A novel redox modulator induces a GPX4-mediated cell death that is dependent on iron and reactive oxygen speciesJ.

CAY10760 is an inhibitor of the protein-protein interaction between RAD51 recombinase and BRCA2 (EC50= 19 μM in a cell-free competitive ELISA).1It decreases homologous recombination by 54% in wild-typeBRCA2-expressing BxPC-3 pancreatic cancer cells when used at a concentration of 20 μM. CAY10760 (20 μM) decreases proliferation of BxPC-3, as well as mutantBRCA2-expressing Capan-1, cancer cells when used alone or in combination with the poly(ADP-ribose) polymerase (PARP) inhibitor olaparib . 1.Bagnolini, G., Milano, D., Manerba, M., et al.Synthetic lethality in pancreatic cancer: Discovery of a new RAD51-BRCA2 small molecule disruptor that inhibits homologous recombination and synergizes with olaparibJ.

GM 1489 is a broad-spectrum inhibitor of matrix metalloproteinases (MMPs) with Ki values of 0.002, 0.1, 0.5, 0.2, and 20 μM for MMP-1, MMP-8, MMP-2, MMP-9, and MMP-3, respectively. It reduces 5-aza-2'-deoxycytidine-induced increases in MMP-1, MMP-2, MMP-3, MMP-7, MMP-9, and MMP-14 expression as well as cell invasion in AsPC-1, BxPC-3, Hs766T, MiaPaCa2, and PANC-1 cancer cells. Topical administration of GM 1489 (100 μg) inhibits increases in ear thickness and epidermal hyperplasia induced by phorbol 12-myristate 13-acetate and phorbol dibutyrate (PdiBu) in mice.
