Abstract:

Homeodomain-interacting protein kinase 2 (HIPK2) is a conserved serine/threonine kinase, which regulate transcription, cell differentiation, proliferation and apoptosis. Previous evidences indicated that HIPK2 could be involved in the pathogenesis of neurodegenerative diseases, suggesting as a novel target for Parkinson's disease (PD) therapeutic development. Herein, gene microarray analysis was performed to verify the key regulatory function of HIPK2 in PD. (Z)-methylp-hydroxycinnamate (ZMHC, 7) with other eighteen compounds were isolated from Cannabis sativa subsp. sativa, growing in Bama Yao Autonomous County, one of the five largest longevity regions of the world. Intriguingly, ZMHC was identified to bind HIPK2 with high affinity through molecular modeling and molecular dynamics (MD) simulations. Moreover, cell morphology, flow cytometry and western blot assay suggested that ZMHC inhibited HIPK2, which attenuated MPP(+)-induced apoptosis in SH-SY5Y cells. In conclusion, these findings discovered a natural product that inhibited HIPK2, and highlighted that ZMHC could be a potential precursor agent for future PD therapy.
