PINK1 Inhibitor

MG149 (Tip60 HAT inhibitor) is a selective and potent Tip60 inhibitor with IC₅₀ of 74 uM, similar potentcy for MOF (IC₅₀ = 47 uM); little potent for PCAF and p300 (IC₅₀ >200 uM). MG 149 inhibits KAT8 and blocks PINK1 kinase activity. MG149 inhibits the phosphorylation of Parkin and ubiquitin, thereby suppressing the initiation of PINK1-dependent mitophagy. MG 149 can reverse chronic restraint stress (CRS) induced hypertension and related molecular changes. MG 149 commonly used in research on diseases such as hypertension and Parkinson's disease.

Isopimaric acid is a coniferous tree defense compound. Isopimaric acid binds to AKT and inhibits mTOR phosphorylation, thereby regulating the AKT/mTOR pathway. Isopimaric acid inhibits oxidative stress, inflammation, microglial migration, apoptosis, autophagic flux, ornithine decarboxylase activity, breast cancer proliferation and metastasis, and fungal spore germination. Isopimaric acid also induces M2 microglial polarization, mitochondrial damage, ROS accumulation, starvation-induced colon cancer cell apoptosis, and breast cancer cell cycle arrest. Isopimaric acid activates potassium channels, regulates sodium channels and calcium channels, reduces myocardial excitability, and improves arrhythmia. Isopimaric acid acts as an oxidative substrate for CYP6BW1/3, down-regulates PINK1/Parkin, and regulates calcium homeostasis, oxidative phosphorylation, EMT, and the Wnt pathway. Isopimaric acid exhibits activity against drug-resistant Staphylococcus aureus, repels feeding, and promotes the growth of rice seedlings. Isopimaric acid is suitable for research related to epilepsy, tumors, drug-resistant bacterial infections, atrial fibrillation, hypertension, hyperlipidemia, pulmonary tuberculosis, etc.
