A macromolecule comprising a dendrimer having surface amino groups to which at least one platinum-containing moiety is attached is provided. The macromolecule may have a plurality of platinum-containing moieties attached to the surface amino groups. Alternatively, the macromolecule may comprise a dendrimer having surface amino groups to which at least two different moieties are attached, a first moiety being a platinum-containing moiety and the second moiety being a pharmacokinetic modifying agent or targeting agent. Pharmaceutical compositions comprising the macromolecules and uses of the macromolecules for treating or suppressing the growth of a cancer is also described.

The first total synthesis of oxazolomycin A, a structurally novel oxazole polyene gamma-lactam/beta-lactone antibiotic, is described. Key features Include the stereocontrolled construction of the right-hand heterocyclic core by taking advantage of an In(III)-catalyzed Conia-ene type cyclization and the asymmetric synthesis of the left-hand segment starting with a Cinchona alkaloid-catalyzed cyclocondensation of an aldehyde with an acid chloride.
