• Biologische Aktivität

  DDO-7263, a 1,2,4-Oxadiazole derivative, is a potent Nrf2-ARE activator. DDO-7263 upregulates Nrf2 through binding to Rpn6 to block the assembly of 26S proteasome and the subsequent degradation of ubiquitinated Nrf2. DDO-7263 induces Nrf2 translocation into the nucleus. DDO-7263 inhibits of NLRP3 inflammasome activation. DDO-7263 exerts anti-inflammatory activity and has the potential for neurodegenerative diseases research, such as Parkinson's disease (PD)[1][2]. DDO-7263 (20 μM; 2-24 h) can upregulate the protein levels of HO-1 and NQO1 in concentration-dependent manners[1]. DDO-7263 (2.5, 5, 10, 20, 40, 80 μM; 24 h) can upregulate the survival rate of PC12 and THP-Ms cell after 400 μM H2O2 in a concentration-dependent manner. DDO-7263 alone has no significant decrease on cell survival rate[1]. DDO-7263 (10-100 mg/kg/day; IP; for 10 days) improves the behavioral abnormalities induced by MPTP in mice, significantly attenuates chemically induced dopaminergic neuron loss of tyrosine hydroxylase (TH) in the substantia nigra (SN) and striatum of the mouse brain and inhibits the secretion of inflammatory factors[1]. DDO-7263 (7, 35, 70 mg/kg; IP) has a T1/2 of 3.32 hours and a Cmax of 1.38 mg/mL for rats[1].
