摘要: In the course of screening for anti-Parkinsonian drugs from a library traditional herbal medicines, we found that extracts choi-joki-to and daio-kanzo-to protected cells MPP+-induced cell death. Because commonly contain genus Glycyrrhiza, isolated licopyranocoumarin (LPC) glycyrurol (GCR) as potent neuroprotective principals Glycyrrhiza. LPC GCR markedly blocked neuronal PC12D death disappearance mitochondrial membrane potential, which were mediated by JNK. inhibited JNK activation through suppression reactive oxygen species (ROS) generation, thereby inhibiting These results indicated derived would be promising drug leads PD treatment in future.
