Odor: characteristic
Use: Imperatorin inhibit T cell-receptor-mediated proliferation in human primary T cells in a concentration-dependent manner. Both compounds also induce apoptosis. While imperatorin induces DNA fragmentation at the G1/S phase of the cell cycle, heraclenin induces DNA fragmentation at the G2/M phases of the cell cycle, thus despite a close structural similarity they induce apoptosis in mechanistically different ways. Imperatorin inhibits HIV-1 replication as well as the expression of ICAM-1 in U937 foam cells. Imperatorin can function as a cancer suppressor by inducing apoptosis in HepG2 cells through both death-receptor- and mitochondria-mediated pathways. Furthermore, the in vivo antitumor activities of Imperatorin are significant with negligible weight loss and damage to the host. Imperatorin can also cause apoptosis in human promyelocytic leukaemia, HL-60 via the cytochrome c/caspase-9 pathway. Imperatorin was mutagenic and induced transformation of mouse fibroblast cell lines, whereas it provided inhibiting effects on mutagenesis and carcinogenesis induced by various carcinogens.
