Product Description
Major constituent of St. John’s wort, a herbal remedy widely used for the treatment of depression. Inhibits the reuptake of neurotransmitters in synapses. Activator of the pregnane X receptor (PXR), which serves as a key regulator of CYP3A4 transcription, a member of the cytochrome (CYP) P450 enzyme system. Specifically activates TRPC6 channels. Represents an interesting lead-structure for a new class of antidepressants. Displays several other biological properties of potential pharmacological interest, including antibacterial, anti-inflammational, antitumoral and anti-angiogenic effects. Induces apoptosis in various cancer cells.

Product Description
Exhibits antifungal and cytotoxic activity against some tumor cell lines partly attributed to inhibition of Ras-inducible genes. Inhibits proliferation of mouse and human T cells and modulates production of cytokines during T cell activation. Facilitates the ubiquitinylation process of cyclin D1. Has been identified as a potent and selective inhibitor of threonine/tyrosine-specific kinase, MEK, and other protein kinases that contain a conserved cysteine residue in the ATP-binding site in both in vitro and in vivo studies.

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.
