Product Description
Represents a new class of natural compounds, which inhibit proliferation in eukaryotes by blocking nuclear export. As potent as leptomycin B (Prod. No. ALX-380-100) and specific for G1/S checkpoint. Cytotoxic secondary metabolite (IC50=50pg/ml in mouse cell line L929) that arrests tumor cells in the G1 phase at remarkably low concentrations (50pg/ml in HeLa cell line KB3.1). Inhibits the binding between the nuclear export signal (NES) of proteins and the chromosome maintenance region protein (CRM1). Anticancer compound. Belongs to the family of orphan ligands which include polyketides like leptomycin B, callystatin A and other related compounds.

Product Description
Cytotoxic secondary metabolite that inhibits cell growth of mammalian cell lines in the picomolar range (IC50=0.2ng/ml with L929 mouse cells) including multidrug resistant (MDR) HeLa cells (IC50=0.1ng/ml with KB-V1). Like leptomycin B (Prod. No. ALX-380-100), ratjadone C binds covalently to the nuclear export protein CRM1. It inhibits cargo protein binding to the leucine-rich nuclear export sequence and thereby blocks nuclear export.

HAZARD: HARMFUL.

Product Description
Inhibitor of intracellular protein transport and protein secretion, interfering with trafficking in the trans-Golgi network, leading to the accumulation of cycling proteins in ERGIC clusters. Blocks ADP-ribosylation factor (Arf) in an inactive GDP-bound conformation and thereby prevents binding of COPI coats to ERGIC and Golgi membranes. Upon brefeldin A treatment the Golgi rapidly tubulates and fuses with the ER by an energy-, temperature-, and microtubule-dependent process. In contrast, the drug has little effect on the ERGIC, which keeps its identity, although the ERGIC clusters become larger and more uniformly distributed in the cytoplasm of the cells. Inhibits intracellular collagen degradation. Also inhibits apical Na+ channels in epithelia. Induces apoptosis.
