Isofistularin-3, as a DNA demethylating agent, induces cell cycle arrest and sensitization to TRAIL in cancer cells. Isofistularin-3 can be used as an ADC cytotoxin.Isofistularin-3 is a direct, DNA-competitive DNMT1 inhibitor, with an IC50 of 13.5 μM.
LBW242 is a 3-mer and Smac mimetic and is an effective and orally active proapoptotic IAP inhibitor. LBW242 has activity against multiple myeloma and potentiates TRAIL- and anticancer drug-mediated cell death of ovarian cancer cells. LBW242 displays effec
Azadirone is a limonoid tetranortriterpene. Azadirone can sensitize cancer cells to tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) through ROS-ERK-CHOP-mediated up-regulation of DR4 and DR5 signaling, down-regulation of cell survival prot
Hexyl decanoate, the first trail pheromone compound identified in a stingless bee, Trigona recursa. Hexyl decanoate is dominant component of gland secretions.
PBOX-15 is a novel microtubule-targeting agent that induces apoptosis, upregulates death receptors, and enhances TRAIL-mediated apoptosis in multiple myeloma cells. It also inhibits T cell migration through post-translational modification of tubulin. Pbox
Cyclopamine-KAAD is a potent inhibitor of hedgehog signaling with an IC50 value of 20 nM in a Shh-LIGHT2 assay. It blocks binding of BODIPY-cyclopamine to cells expressing Smoothened (Smo) in a dose-dependent manner. Cyclopamine-KAAD is cell-permeable and binds to SmoA1 to promote its exit from the endoplasmic reticulum. It inhibits the invasion and migration (45.9 and 43.3% inhibition, respectively) of Bel-7402 hepatocarcinoma cells and decreases the expression of nuclear glioma-associated oncogene 1 (Gli1) and cytosolic MMP-9, pERK1, and pERK2 proteins in a dose-dependent manner. Cyclopamine-KAAD also increases TRAIL-mediated cell death in NCH82 and NCH89 human glioblastoma cultures and upregulates expression of the death receptors DR4 and DR5 in LN229 and U251 glioma cells.
Nemadipine A is an L-type calcium channel blocker that induces morphological and growth defects in wild-type C. elegans and those with hypoexpression of egl-19, which encodes the only L-type calcium channel α1-subunit in the C. elegans genome. It also inhibits L-type calcium channels in chick ciliary neurons. Nemadipine A increases TRAIL-induced cytotoxicity and synergistically enhances caspase-8 and caspase-3 activation in a concentration-dependent manner in H1299 lung adenocarcinoma cells. It also decreases Survivin expression when used alone or in combination with TRAIL in A549 cells.
Fluphenazine is a traditional antipsychotic compound that tightly binds the dopamine D2 receptor (Ki = 0.55 nM) and also reversibly inhibits calmodulin at micromolar concentrations. Fluphenazine-N-2-chloroethane is a derivative of fluphenazine that contains an alkylating chlorethylamine chain, which produces irreversible protein binding. It is a relatively selective, irreversible antagonist of D2 receptors both in vitro (IC50 = 100 nM) and in vivo, inactivating approximately 90% of D2 receptors in mice within 4 hours of treatment. Through this action, fluphenazine-B-2-chloroethane can be used to induce catalepsy in mice. It irreversibly inhibits calmodulin at higher doses (IC50 = 10 μM), which can sensitize cancer cells to TRAIL-induced apoptosis.
High affinity XIAP antagonist (Kd = 16 nM for the BIR3 domain of XIAP). Exhibits cytotoxicity in a wide range of cancer cell lines in vitro (EC50 = 13 nM in MDA-MB-231 cells). Also displays antitumor activity in a mouse breast cancer xenograft model. Enhances TRAIL-induced apoptosis in chronic lymphocytic leukemia (CLL) cells.
