Cyclotheonellazoles D-I, Potent Elastase Inhibitory Thiazole-Containing Cyclic Peptides from Theonella sp. (2131)
Description
                Six new thiazole-containing cyclic peptides, the cyclotheonellazoles D-I (1-6), were isolated from the Australian marine sponge Theonella sp. (2131) with their structures assigned by comprehensive 1D and 2D NMR spectroscopic and MS spectrometric
