S6962 TPEN

TPEN (TPEDA) is a specific cell-permeable heavy metal chelator that induces apoptosis in NB4 cells via negatively regulating intracellular NO and Zn2+ signaling. This compound may be a potential therapeutic strategy for APL (acute promyelocytic leukemia). It induces DNA damage and increases intracellular ROS production and also inhibits cell proliferation.

S3292 (3R,8S)-Falcarindiol Falcarindiol (FAD, (3R,8S)-Falcarindiol, FaDOH) is a natural polyacetylene compound found rich in many plants of the Umbelliferae family. Falcarindiol suppresses LPS-stimulated expression of inducible nitric oxide synthase (iNOS), tumor necrosis factor alpha (TNFα), interleukin-6 (IL-6), and interleukin-1 beta (IL-1β). Falcarindiol attenuates the LPS-induced activation of JNK, ERK, STAT1, and STAT3 signaling molecules.

S9374 2',5'-Dihydroxyacetophenone 2',5'-Dihydroxyacetophenone (DHAP, 2-Acetylhydroquinone, Quinacetophenone) is a mixture of dihydroxyacetophenone isomers is used in food flavouring. This compound significantly inhibits NO production via the suppression of iNOS expression. It significantly decreases levels of the pro-inflammatory cytokines TNF-α and IL-6 by blocking the ERK1/2 and NF-κB signaling pathways.
