Application


  • Booklice Liposcelis bostrychophila are efficiently attracted by the combination of 2,3,5,6-tetramethylpyrazine and ultraviolet light.: This study demonstrates that the combination of 2,3,5,6-tetramethylpyrazine and ultraviolet light effectively attracts booklice, suggesting a potential application for pest management in stored product environments (Tanaka et al., 2024).

  • 2,3,5,6-Tetramethylpyrazine protects retinal photoreceptors against endoplasmic reticulum stress by modulating ATF4-mediated inhibition of PRP aggregation.: The research highlights the neuroprotective effects of 2,3,5,6-tetramethylpyrazine, showing its potential in treating retinal diseases by protecting photoreceptors from stress-induced damage (Huang et al., 2021).

  • Tetramethylpyrazine-Inducible Promoter Region from Rhodococcus jostii TMP1.: The study identifies a promoter region in Rhodococcus jostii TMP1 that is inducible by tetramethylpyrazine, which could be utilized in genetic engineering and biotechnology applications (Stanislauskienė et al., 2018).

A series of novel acylpiperazinyl Ligustrazine derivatives was designed, synthesized, and their protective effects on damaged ECV-304 cells and antiplatelet aggregation activities were evaluated. The results showed that compound E33 displayed most potential protective effects on the ECV-304 cells damaged
