Product Description
The furanocoumarins heraclenin (Prod. No. ALX-350-303) and imperatorin (Prod. No. ALX-350-302) 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. Inhibits voltage-dependent calcium channel.
