Two new metabolites, perthamides C and D, have been isolated from the marine sponge Theonella swinhoei. Their structures were determined by interpretation of NMR and ESIMS data. All compounds exhibited in vivo potent anti-inflammatory activity. Biological

The peptide antibiotic P168 contained a new amino acid, (2S,4S)-2-amino-6-hydroxy-4-methyl-8-oxodecanoic acid (6) and an amine, (S)-N1,N1-dimethylpropane-1,2-diamine (4) along with other unusual amino acids.The structure of the peptide was determined as (I) by in-beam mass spectrometry.

The Hofmann-Loeffler-Freytag reaction, carried out by irradiation in sulphuric acid of N-chloro-l-amino-acids 3a-d, gives δ-chlorinated compounds which can be cyclized to l-prolines 4a-e. This convenient synthesis does not affect the asymmetric centres of
