Mixed Lineage Kinase Activator

RIP1/RIP3/MLKL activator 1 (Compound 6i) is a potent anti-glioma agent. RIP1/RIP3/MLKL activator 1 induces necroptosis through RIP1/RIP3/MLKL pathway. RIP1/RIP3/MLKL activator 1 exerts acceptable BBB permeability.

Necroptosis inducer 2 is a necroptosis inducer and copper chelator. Necroptosis inducer 2 chelates intracellular free copper ions, disrupts redox homeostasis, elevates ROS levels, disrupts mitochondrial membrane potential, and induces cancer cell necroptosis. Necroptosis inducer 2 upregulates the necroptosis markers p-MLKL and p-RIP3 expression. Necroptosis inducer 2 exhibits anti-tumor activity in mice. Necroptosis inducer 2 can be used for the research of cancer, such as triple-negative breast cancer.

ZBP1/RIP3/MLKL activator 1 (compound 3a) is a synthetically derived quinoline compound. ZBP1/RIP3/MLKL Activator 1 induces DNA damage, enhances intracellular levels of reactive oxygen species (ROS), and triggers apoptosis via the caspase pathway. Furthermore, when apoptosis is inhibited, ZBP1/RIP3/MLKL Activator 1 promotes necroptotic cell death through the ZBP1-RIP3-MLKL pathway. ZBP1/RIP3/MLKL Activator 1 is utilized in oncological research, particularly in the selective targeting of cells with impaired apoptotic function.

RETRA is a RIPK1/RIPK3/MLKL and p73 activator. RETRA mediates plasma membrane disruption, induces ROS accumulation, triggers early mitochondrial hyperpolarization, and synergistically drives necroptosis. RETRA inhibits cancer cells carrying mutant p53 via a p73-dependent salvage pathway. RETRA can be used in research related to cervical cancer and cancers with mutant p53.

NecroIr2 is an iridium(III) complex, serves as necroptosis inducers in Cisplatin (HY-17394)-resistant lung cancer cells (A549R). NecroIr2 selectively accumulates in mitochondria, leading to oxidative stress and loss of mitochondrial membrane potential (MMP). NecroIr2 activates receptor-interacting serine-threonine kinase 3 (RIPK3) and mixed lineage kinase domain-like pseudokinase (MLKL), and regulates CDK4 expression.

NecroIr1 is an iridium(III) complex, serves as necroptosis inducers in Cisplatin (HY-17394)-resistant lung cancer cells (A549R). NecroIr1 selectively accumulates in mitochondria, leading to oxidative stress and loss of mitochondrial membrane potential (MMP). NecroIr1 activates receptor-interacting serine-threonine kinase 3 (RIPK3) and Mixed Lineage Kinase (MLKL), and regulates CDK4 expression.

(E)-2-Hexadecenal (trans-2-Hexadecenal) is an MLK3 activator that induces cytoskeletal remodeling, leading to cell rounding, detachment, and ultimately apoptosis in human and mouse cells. (E)-2-Hexadecenal activates the MLK3 signaling pathway, phosphorylating MKK4/7 and JNK, subsequently activating downstream targets of JNK, such as c-Jun phosphorylation, cytochrome c release, Bax activation, Bid cleavage, and Bim translocation to mitochondria. (E)-2-Hexadecenal has potential applications in research related to sphingolipid signaling pathways.

Topoisomerase I/II Inhibitor 8 (Compound Ru7) is a dual catalytic inhibitor of Topoisomerase I/II, capable of inducing DNA damage and PARP-1 activation, which subsequently leads to the activation of RIPK1, RIPK3, and MLKL, ultimately triggering necroptosis. Topoisomerase I/II Inhibitor 8 demonstrates remarkable anticancer activity by effectively targeting the nuclei of cancer cells and inducing cell death through necroptosis, showing great clinical potential in circumventing drug resistance in cancer treatment.

Anticancer agent 267 (Compound 5q) is the activator for RIPK3 and MLKL. Anticancer agent 267 inhibits the proliferation in a variety of cancer cell lines (IC₅₀ for MDA-MB-231, MDA-MB-486 and MCF-7 is 9.79, 10.77 and 5.94 μM, respectively), arrests cell cycle at subG1 phase, and induces necroptosis in cell MDA-MB-231. Anticancer agent 267 exhibits antitumor activity in mouse xenograft models.
