HERaclenin 是一种天然呋喃香豆素。它浓度依赖性的靶向激活的 T 细胞核因子 (NFAT) ，抑制人原代 T 细胞中 T 细胞受体介导的增殖。

Heraclenin has anticoagulant, and anti-inflammatory activities, it also has mutagenicity in Chlamydomonas reinhardii. Heraclenin can induce apoptosis in Jurkat leukemia cells, it has a strong clastogenic effect . (+)-Heraclenin displays significant levels of antiplasmodial and moderate levels of antimicrobial activities.

METHODS AND RESULTS:Heraclenin, a furocoumarin with an epoxide group in its side chain, was analyzed to see if it induced structural chromosome aberrations and sister-chromatid exchanges (SCEs) in human lymphocytes in vitro. The results were compared directly with those of imperatorin, which differs from Heraclenin only in lacking an epoxide group. An equally strong clastogenic effect was found for both Heraclenin and imperatorin: the number of metaphases with breaks was increased in both cases by approximately a factor of 6. Heraclenin produced a considerable dose-dependent increase in the SCE rate, i.e., by about 60 induced SCEs/metaphase, whereas imperatorin induced only about 4 SCEs/metaphase. CONCLUSIONS: The results are discussed with respect to the occurrence of structural aberrations, which are primarily due to the basic furocoumarin structure itself, whereas the large increase in the SCE rate produced by Heraclenin is most probably significantly influenced by its epoxide group.
