Parishin B
Based on 1 publication(s) in Google Scholar
Parishin B is a multi-target biological agent with anti-epileptic, anti-fascioliasis and anti-breast cancer lung metastasis activities. Parishin B regulates the gene/protein activities of ACLY, unc13c, γ-aminobutynergic system, pro-inflammatory system, antioxidant system, monoaminergic system, ferroptosis-related pathways, as well as GST, CatL, Trx and TRIB3. Parishin B modulates energy-lipid metabolism, synaptic function, neurotransmitter balance, neuroinflammation, oxidative stress, parasite detoxification/invasion processes, as well as apoptosis, cell cycle, proliferation and metastasis of cancer cells[1][2][3]. Parishin B can be used for related research of epilepsy, fascioliasis and breast cancer lung metastasis[3].
