Beschreibung:
Two new cycloheptapeptides, tunicyclins F and G, were isolated from the roots of Psammosilene tunicoides. Their chemical structures were elucidated by extensive analysis of 1D- and 2D-NMR, as well as HR-ESI-MS data. Tunicyclin G contains an unusual α , β -dehydrotryptophan (Δ Z -Trp) residue, which mainly occurs in the cyclic peptides from marine sponge and bacteria.
