J Org Chem . 2010 Apr; 75(13):4344-55. PMID: 20402515
A new sulfated cyclic depsipeptide, termed mutremdamide A, and six new highly N-methylated peptides, termed koshikamides C-H, were isolated from different deep-water specimens of Theonella swinhoei and Theonella cupola. Their...

J Nat Prod . 2010 Jan; 73(3):485-8. PMID: 20078073
Three new anabaenopeptin-like peptides, named paltolides A-C, were isolated from a deep-water specimen of the marine sponge Theonella swinhoei from Palau. Paltolides belong to a rare subgroup of sponge-derived anabaenopeptins...

J Org Chem . 2008 Dec; 74(2):504-12. PMID: 19072692
Six new depsipeptides belonging to two different structural classes, termed celebesides A-C and theopapuamides B-D, have been isolated from the marine sponge Siliquariaspongia mirabilis. Their structures were determined using extensive...

Org Lett . 2007 Jan; 9(4):671-4. PMID: 17256869
The search for a 2'-OH protecting group that would impart ribonucleoside phosphoramidites with coupling kinetics and coupling efficiencies comparable to those of deoxyribonucleoside phosphoramidites led to an assessment of 2'-O-(4-nitrogenated...
