1. Dolastatin 11, a marine depsipeptide, arrests cells at cytokinesis and induces hyperpolymerization of purified actin
R Bai, P Verdier-Pinard, S Gangwar, C C Stessman, K J McClure, E A Sausville, G R Pettit, R B Bates, E Hamel Mol Pharmacol. 2001 Mar;59(3):462-9. doi: 10.1124/mol.59.3.462.
The successful synthesis of dolastatin 11, a depsipeptide originally isolated from the mollusk Dolabella auricularia, permitted us to study its effects on cells. The compound arrested cells at cytokinesis by causing a rapid and massive rearrangement of the cellular actin filament network. In a dose-and time-dependent manner, F-actin was rearranged into aggregates, and subsequently the cells displayed dramatic cytoplasmic retraction. The effects of dolastatin 11 were most similar to those of the sponge-derived depsipeptide jasplakinolide, but dolastatin 11 was about 3-fold more cytotoxic than jasplakinolide in the cells studied. Like jasplakinolide, dolastatin 11 induced the hyperassembly of purified actin into filaments of apparently normal morphology. Dolastatin 11 was qualitatively more active than jasplakinolide and, in a quantitative assay we developed, dolastatin 11 was twice as active as jasplakinolide and 4-fold more active than phalloidin. However, in contrast to jasplakinolide and phalloidin, dolastatin 11 did not inhibit the binding of a fluorescent phalloidin derivative to actin polymer nor was it able to displace the phalloidin derivative from polymer. Thus, despite its structural similarity to other agents that induce actin assembly (all are peptides or depsipeptides), dolastatin 11 may interact with actin polymers at a distinct drug binding site.
2. Biosynthesis of (R)-beta-tyrosine and its incorporation into the highly cytotoxic chondramides produced by Chondromyces crocatus
Shwan Rachid, Daniel Krug, Kira J Weissman, Rolf Müller J Biol Chem. 2007 Jul 27;282(30):21810-7. doi: 10.1074/jbc.M703439200. Epub 2007 Jun 1.
The chondramides are mixed non-ribosomal peptide/polyketide secondary metabolites produced by the myxobacterium Chondromyces crocatus Cm c5, which exhibit strong cytotoxic activity. On the basis of their striking structural similarity to the marine depsipeptides jaspamides, the chondramides have been assumed to incorporate a (R)-beta-tyrosine moiety, an expectation we confirm here. Thus, the recent sequencing of the chondramide biosynthetic gene cluster provided the opportunity to probe the shared origin of this unusual beta-amino acid. We demonstrate here that (R)-beta-tyrosine is produced directly from l-tyrosine by the aminomutase CmdF. Along with the tyrosine aminomutase SgcC4 from the C-1027 enediyne pathway, this enzyme belongs to a novel family of tyrosine aminomutases related to the ammonium lyase family of enzymes but exhibits opposite facial selectivity for the hydroxycinnamate intermediate. We also show that the adenylation (A) domain in the chondramide pathway, which activates the beta-tyrosine building block, exhibits the required preference for (R)-beta-tyrosine, further arguing against alternative origins for the moiety in the chondramides. Comparison to the (S)-beta-tyrosine specific A domain SgcC1 should enhance our understanding of the structural and stereochemical determinants guiding amino acid selection by non-ribosomal peptide synthetase multienzymes.
3. Chondramides, novel cyclodepsipeptides from myxobacteria, influence cell development and induce actin filament polymerization in the green alga Micrasterias
A Holzinger, U Lütz-Meindl Cell Motil Cytoskeleton. 2001 Feb;48(2):87-95. doi: 10.1002/1097-0169(200102)48:23.0.CO;2-C.
The effects of chondramides A-D, new actin targeting cyclodepsipeptides from the myxobacterium Chondromyces crocatus, are probed on the unicellular green alga Micrasterias denticulata, a model organism for studies on cytomorphogenesis. All four chondramides readily enter the cells and cause severe shape malformations when applied during growth. However, the four derivatives have different lowest effective concentrations. Chondramide A: 20 microM, chondramide B: 15 microM, chondramide C: 5 microM chondramide D: 10 microM. At the ultrastructural level, chondramide C, the most effective drug, causes the appearance of abnormal, dense F-actin bundles, and a substantial increase in ER, which covers large parts of the developing semicell. Also the secondary cell wall is malformed by the drug. When chondramide C effects are investigated by means of indirect immunofluorescence, alterations of the F-actin system are also visible. Instead of the cortical F-actin network of untreated controls, distinct parts of the cell are covered by abundant F-actin aggregations. Phalloidin staining of chondramide C treated cells results in a decreased fluorescence in a time-dependent manner due to binding competitions between these drugs. F-actin polymerizing and bundling capacities of chondramides A-D are presented in Micrasterias for the first time, and may in future make this substances a useful tool for cell biological research.
