Abstract
The cyclomarins are cyclic heptapeptides from marine streptomycetes containing four
rather unusual amino acids. Interestingly, the cyclomarins address two completely
different targets: ClpC1, a subunit of the caseinolytic protease of Mycobacterium tuberculosis (MTB), as well as PfAp3Aase of Plasmodium falciparum. Therefore, the cyclomarins are interesting lead structures for the development of
drugs targeting tuberculosis and malaria. As a result, several synthetic protocols
towards the synthesis of these unusual building blocks as well as the natural products
themselves have been developed, which will be discussed in this review.
