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.

2-Methylhexacosane is a saturated hydrocarbon and an insect pheromone.1,2It has been found in the cuticle ofM. dasystomusfemales, but not males, where it contributes to the mating behavior of males, as well as inD. melanogasterfemales where it modulates aggression of males towards females. 2-methylhexacosane has also been found in yellow jacket (V. vulgaris) trail extracts.3 1.Spikes, A.E., Pashen, M.A., Millar, J.G., et al.First contact pheromone identified for a longhorned beetle (Coleoptera: Cerambycidae) in the subfamily PrioninaeJ.
