, each of the R groups may be the same or different, or the two R groups, together with the nitrogen atom to which they are attached, may form a 5-14 membered heterocyclic ring. These compounds display activity against a range of mammalian cancer cell lines. New synthetic routes to new and known variolin compounds, together with novel intermediates, are also disclosed. New antitumour activity of known variolin compounds is also described.
