Synthesis and Structure Determination of Kahalalide F1,2
Kahalalide F, the only member of the family of peptides called kahalalides, isolated from the sacoglossan mollusc Elysia rufescens and the green alga Bryopsis sp., with important bioactivity, is in… Expand

The aim of this contribution is to offer an unambiguous and general nomenclature system that enables researchers to represent all cyclic and branched homo- and hetero-detic peptides in a coherent manner in one-line text - as long as their as constituents can be represented in (three)-letter codes.

The solid phase synthesis of 132 novel analogues of kahalalide F revealed that KF is highly sensitive to backbone stereotopical modification but not to side chain size modification, suggesting that this compound has a defined conformational structure. Expand
Kahalalide B. Synthesis of a natural cyclodepsipeptide
Abstract A suitable combination of soluble and polymeric protecting groups and coupling reagents has allowed the first synthesis of the natural cyclodepsipeptide of marine origin Kahalalide B to be… Expand

HPLC, high-field NMR, and biological activity studies showed that the correct stereochemistry of the natural product is that proposed by Rinehart et al, whereas the stereochemistry proposed by Scheuer et al. is that of a biologically less active diastereoisomer. Expand
Synthesis of peptides containing α, β-didehydroamino acids. Scope and limitations
α, β-Didehydroamino acids, which are key components of both natural andde novo peptides, are frequently encountered in naturally occurring peptides — mostly of microbial and fungal origin and/or from… Expand
Solid-phase synthesis of the cyclic lipononadepsipeptide [N-Mst(Ser1), d-Ser4, L-Thr6, L-Asp8, L-Thr9]syringotoxin.
An optimized solid-phase strategy for the preparation of the cyclic lipononadepsipeptide is reported, based on the use of a mild orthogonal protection scheme and the incorporation of the nonproteinogenic amino acid (Z)-Dhb into the peptide chain as the dipeptide Fmoc-Thr(tBu)-(Z)-dhb-OH. Expand
