Paraptosis Inducer

MCB-613 is a potent Steroid receptor coactivator SRC small molecule ‘stimulator’ (SMS), super-stimulates SRCs’ transcriptional activity. MCB-613 increases SRCs’ interactions with other coactivators and markedly induces ER stress coupled to the generation of reactive oxygen species (ROS). MCB-613 is a SMS that target oncogenes can be exploited as anti-cancer agents by over-stimulating the SRC oncogenic program.

BQZ-485 is a a potent GDI2 inhibitor through the interaction with Tyr245. BQZ-485 disrupts the intrinsic GDI2-Rab1A interaction, thereby abolishing vesicular transport from the endoplasmic reticulum (ER) to the Golgi apparatus and initiating subsequent paraptosis events.

DHW-221 is a potent orally active dual PI3K/mTOR inhibitor, exhibiting low nanomolar potency against all four Class I PI3K isoforms and mTOR (PI3Kα, IC₅₀ = 0.50 nM; PI3Kβ, IC₅₀ = 1.9 nM; PI3Kγ, IC₅₀ = 1.8 nM; PI3Kδ, IC₅₀ = 0.74 nM; mTOR, IC₅₀ = 3.9 nM). DHW-221 exerts antitumor effects by blocking the PI3K/Akt/mTOR pathway and inducing mitochondrial apoptosis and paraptosis (via Endoplasmic Reticulum (ER) stress and MAPK signaling) and arrests cell cycle, thereby inhibiting cell migration, invasion and angiogenesis. DHW-221 inhibits tumor growth in both the A549/Taxol (HY-B0015) and the HCC827 xenograft mouse models. DHW-221 can be used for non-small cell lung cancer (NSCLC), colon and breast cancer research.

fac-[Re(CO)3(L3)(H2O)][NO3] (compound 3), the rhenium(I) tricarbonyl aqua complex, is an anticancer agent associated with mitochondrial dysfunction. fac-[Re(CO)3(L3)(H2O)][NO3] is cytotoxic to prostate cancer cells with IC₅₀=0.32 μM (PC-3 cells). fac-[Re(CO)3(L3)(H2O)][NO3] mainly accumulates in mitochondria, down-regulates ATP production in PC3 cells, and promotes paraptosis. However, fac-[Re(CO)3(L3)(H2O)][NO3] did not induce necrosis, apoptosis and autophagy.

Chalcomoracin is an orally effective anticancer agent. Chalcomoracin exhibits anticancer, antibacterial, and α-glucosidase inhibitory activities, with an IC₅₀ of 14.23 µM against yeast α-glucosidase and an IC₅₀ of 5.5 μM against FabI of Staphylococcus aureus. Chalcomoracin reduces the phosphorylation levels of ERK, JNK, and P38; enhances the phosphorylation level of ERK1/2; regulates the MAPK, mTOR, AKT, and p53 signaling pathways; upregulates the expression of Chop, Bip, PINK1, GRP78, and GADD153; and downregulates the expression of Alix. Chalcomoracin induces apoptosis (apoptosis), endoplasmic reticulum stress (endoplasmic reticulum stress), paraptosis (paraptosis), ROS production, mitophagy (mitophagy), and autophagy (autophagy); it inhibits cancer cell viability, colony-forming ability, migration, invasion, proliferation, tumorigenesis, fatty acid synthesis, S. aureus growth, vitreous-stimulated retinal cell activity, and cell cycle progression at the G0/G1 phase. Chalcomoracin can be used in research related to hepatocellular carcinoma, non-small cell lung cancer, triple-negative breast cancer, prostate cancer, proliferative vitreoretinopathy, pancreatic cancer, diabetes, and bacterial infections.

(E/Z)-MCB-613 is a pan-Steroid Receptor Coactivator (SRC) stimulator. (E/Z)-MCB-613 overstimulates SRC activity in cancer cells resulting in excessive generation of reactive oxygen species (ROS), leading to cell stress and death by a process called paraptosis. (E/Z)-MCB-613 is a cytotoxic molecule that plays an important role in cancer.

[Ag(2,2′-bipy)(dppe)][CF3SO3] (compound 4) can induce cell paraptosis, and can be used for stusy of resistant ovarian cancer.
