Piperlongumine (PL) is a natural product constituent of the fruit of the Long pepper (Piper longum),[1] a pepper plant found in southern India and southeast Asia.

Piperlongumine may have anti-cancer properties. In in vitro experiments, it selectively kills some types cancer cells over normal cells.[1] One study in a xenograft mouse model of cancer showed that piperlongumine inhibits the growth of malignant breast tumors and their associated metastases.[1][2] Its anticancer effects may be due to silencing the GSTP1 gene.[3]

Some piperlongumine derivatives were potent anti-inflammatory agents.[4] The synthesis typically involved Schotten-Baumann reaction between the acid chloride of 3,4,5-trimethoxycinnamic acid with the corresponding amines. Wang et al., evaluated piperlongumine as a novel senolytic agent.[5]
