New nodularins: A general method for structure assignment

A general method has been developed for assigning the structures of nodularin, a potent hepatotoxin, tumor promoter, and protein phosphatase inhibitor, and minor components isolated from a cultured and a bloom sample of the cyanobacterium Nodularia spumigena. It consists of (1) FABMS analysis (determination of molecular weight and molecular formula), (2) 1H NMR spectroscopy on the parent compound and chiral GC analysis of an acid hydrolyzate (identification and stereochemistry of amino acid components), (3) ozonolysis followed by NaBH4 reduction (conversion to a linear peptide), and (4) FABMS/CID/MS analyses of the linear peptide and the parent compound (sequence analysis). The method has been employed in assigning structures to three new nodularins (2-4) and can be applied to other cyclic peptides containing alpha,beta-dehydroamino acid unit(s), especially the related microcystins, cyclic heptapeptide hepatotoxins. Two nodularins, [DMAdda3]nodularin (2) and [(6Z)Adda3]nodularin (3), were obtained from a bloom sample collected from Lake Ellesmere (New Zealand), and [D-Asp1]nodularin (4) was isolated from cultured cells (strain L-575). The LD50s of 2 and 4 were 150 and 75 mug/kg (ip, mice), respectively, but 3 did not show apparent toxicity at 2.0 mg/kg.

beta-Pseudopeptide foldamers. the homo-oligomers of (4R)-(2-oxo-1,3-oxazolidin-4-yl)-acetic acid (D-Oxac)

A total synthesis in solution and a conformational analysis of the homo-oligomers of (4R)-(2-oxo-1,3-oxazolidin-4-yl)-acetic acid (D-Oxac) to the tetramer level are described. As the D-Oxac building block contains both an oxazolidin-2-one and a beta-amino acid group, it may represent a new type of conformationally constrained tool for the construction of beta-pseudopeptide foldamers. A conformational investigation using NMR and an extensive, unconstrained analysis with a Monte Carlo search to the octamer level, both in water and in chloroform, showed that these homo-oligomers tend to fold in a regular helical structure in a competitive solvent, such as water. Since aqueous solutions are of major relevance for biological systems, these molecules are good candidates for application to these environments.

A novel synthesis of a key intermediate for (+)-biotin from L-aspartic acid

The aldol reaction of an N-Cbz-3-amino-4-butanolide 4, derived from L-aspartic acid, with formaldehyde gave the trans-disubstituted 3-amino-4-butanolide 5 stereoselectively. Following protection of the hydroxyl group of 5, amidation and oxidation provided the beta-substituted L-asparagine derivative 6. The Hofmann rearrangement of 6 with sodium hypochlorite in the presence of sodium hydroxide and subsequent hydrogenation gave the bicyclic lactone 11, which upon dibenzylation and thionation, gave the thiolactone 2, a key intermediate for the synthesis of (+)-biotin (1).
