title: A new endothelin C-terminal analogue IBDP 064 antagonizes endothelin-3-induced cell proliferation.
abstract: A series of C-terminal linear endothelin analogues were prepared and their activities in C6 rat glioma cell line were tested. Among the synthetic analogues, IBDP 064, Fmoc-Leu-Asp-Ile-Ile-Trp-OH, was the most potent and selective inhibitor of endothelin-3-induced cell proliferation. Its action was comparable with that of the previously described peptide IRL 1038, [Cys11-Cys15]-ET-1(11-21), an ETB specific inhibitor.
