Background Herbacetin, a flavonoid present in many types of herbs, which include linaceae, ephedraceae, and crassulaceae, exhibits a range of medicinal properties. 1-methyl-4-phenylpyridinium (MPP+) is one of the neurotoxins used in cell-based Parkinson’s disease (PI) models. Whereas the precise chemical mechanism of iron association with free radical cell damage and apoptosis is yet unknown, intracellular irons are a key factor for MPP+-derived apoptosis. Methods We examine whether the antiapoptotic properties of flaxseed bioflavonoid herbacetin (HB) are associated with the stimulation of the intrinsic caspase-dependent pathway and exposing of MPP+ caused neuronal death in the human dopaminergic neuroblastoma cells. Four groups were created out of the cells. Groups I, II, III, and IV are the control, HB+MPP+, MPP+, and HB, respectively. Following a 24-hour incubation period, the cells were subjected to several parameters. Results We discovered in neuroblastoma cells that HB dramatically reduced the cell death induced by MPP+. Additionally, HB significantly reduced the formation of ROS and counteracted the reduction in MMP resulting from MPP+ treatment. HB reduces the stimulation of the intrinsic caspase-dependent apoptotic mechanism and suppresses the MPP+-mediated apoptotic signalling pathway. Furthermore, HB predicted a better binding interaction with alpha-synuclein and drastically decreased alpha-synuclein expression and accumulation in neuroblastoma cells. Conclusion Consequently, our findings imply that HB shields neurons by reducing oxidative stress, alpha-synuclein misfolding in neuroblastoma, and apoptosis prompts the death of neuroblastoma cells.
