QD325 is a potent redox modulator for the Treatment of Pancreatic Ductal Adenocarcinoma. Nascent RNA sequencing following treatments with QD325 revealed induction of stress responses in the nucleus, endoplasmic reticulum, and mitochondria of pancreatic ca
TW9 is a dual inhibitor of bromodomain 2 (BD2) in bromodomain-containing protein 4 (BRD4) and histone deacetylase 1 (HDAC1; IC50s = 0.074 and 0.29 μM, respectively).1It is selective for BD2 over BD1 in BRD4 (IC50= 0.72 μM) and for HDAC1 over HDAC2 (IC50= 2.5 μM). TW9 (50 nM) induces apoptosis in, and inhibits proliferation of, MIA PaCa-2 pancreatic cancer cells. It induces cell cycle arrest at the G1phase in HPAC pancreatic cancer cells when used at a concentration of 2 μM. TW9 acts synergistically with gemcitabine to reduce the viability of HPAC cells. 1.Zhang, X., Zegar, T., Weiser, T., et al.Characterization of a dual BET HDAC inhibitor for treatment of pancreatic ductal adenocarcinomaInt.

Aspulvinone O is a fungal metabolite that has been found in P. variotti and has antioxidant and anticancer activities.1,2 It scavenges 2,2-diphenyl-1-picrylhydrazyl radicals in a cell-free assay (IC50 = 11.6 μM).1 Aspulvinone O inhibits aspartate transaminase 1 (GOT1; Kd = 3.32 μM) and is cytotoxic to PANC-1, AsPC-1, and SW1990 pancreatic cancer cells (IC50s = 20.54-26.8 μM).2 It reduces the oxygen consumption rate (OCR) and induces apoptosis in SW1990 cells. Aspulvinone O (2.5 and 5 mg kg) reduces tumor growth in an SW1990 mouse xenograft model. |1. Zhang, P., Li, X.-M., Wang, J.-N., et al.

Avarol induces apoptosis in pancreatic ductal adenocarcinoma cells by activating PERK-eIF2α-CHOP signaling. Avarl also acts as a competitive AChE inhibitor which are non-hepatotoxic and neuroprotective agents for Alzheimer's disease.
UA8967 is a membrane-active anti-tumor agent. Cytotoxicity studies in six pancreatic cancer cell lines, one normal human pancreatic ductal epithelial line and two colon cancer cells showed the IC50s UA8967 ranged from 12–61 μM for exposure times of 72 h. There was also no selective inhibition of DNA, RNA or protein synthesis after exposure to UA8967. UA8967 is observed to affect the plasma membrane.
Deltarasin is a high affinity PDEδ-KRAS interaction inhibitor. Deltarasin can inhibit KRAS-PDEδ interactions by binding to a hydrophobic pocket on PDEδ, resulting in the impairment of cell growth, KRAS activity, and RAS RAF signaling in human pancreatic ductal adenocarcinoma cell lines. The anti-cancer cell activity of deltarasin can be enhanced by simultaneously blocking tumor protective autophagy
