Chalcomoracin
Chalcomoracin is an orally active 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.

Elevated LC3B and cleaved Caspase-3 levels in tumors as confirmed by immunohistochemistry and immunofluorescence.
Caused no significant change in mouse body weight, indicating no overt toxicity.
Achieved a 124.07% T/C rate and 0% tumor inhibition rate.
Failed to increase LC3-II and cleaved Caspase-3 levels in Atg7-knockdown tumors.
Showed no significant effect on p-mTOR/mTOR or p-S6/S6 levels relative to the vehicle group.
Caused no significant change in mouse body weight.
-
Animal Model:BALB/c nude (female, 5 weeks old, 18 g, subcutaneous xenograft model injected with PANC-1 cells)[5]
-
Dosage:20 mg/kg
-
Administration:i.p.; daily; 27 days
-
Result:Alone achieved a 52.50% T/C rate and 47.80% tumor inhibition rate.
Alone downregulated p-mTOR/mTOR and p-S6/S6 levels in tumor tissues.
Alone upregulated cleaved Caspase-3 expression in tumor tissues.
Alone increased the LC3-II/LC3-I ratio in tumor tissues.
Concurrent NAC treatment reversed these effects, resulting in a 172.11% T/C rate and 0% tumor inhibition rate, with no significant change in autophagy or apoptosis markers relative to the NAC-only group.
Caused no significant change in mouse body weight across groups.
