PINK1/Parkin Modulator

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.

BIO-2007817 is a Parkin positive allosteric modulators (PAMs). BIO-2007817 enhances the activity of wildtype Parkin. BIO-2007817 stimulates Parkin (an E3 ligase)autoubiquitination and induces the appearance of monoubiquitinated forms of Miro1 (EC₅₀: 0.17 μM).
