Halichondrin B is a polyether macrolide originally isolated from the marine sponge Halichondria okadai by Hirata and Uemura in 1986. [1] In the same report, these authors also reported the exquisite anticancer activity of halichondrin B against murine cancer cells both in culture and in in vivo studies. Halichondrin B was highly prioritized for development as a novel anticancer therapeutic by the United States National Cancer Institute [2] and, in 1991, was the original test case for identification of mechanism of action (in this case, tubulin-targeted mitotic inhibitor) by NCI's then-brand-new "60-cell line screen" [3] [4]

The complete chemical synthesis of halichondrin B was achieved by Yoshito Kishi and colleagues at Harvard University in 1992, [5] an achievement that ultimately enabled the discovery and development of the structurally simplified and pharmaceutically optimized analog eribulin (E7389, ER-086526, NSC-707389). [6] [7] Eribulin was approved by the U.S. Food and Drug Administration on November 15, 2010, to treat patients with metastatic breast cancer who have received at least two prior chemotherapy regimens for late-stage disease, including both anthracycline- and taxane-based chemotherapies. [8] Eribulin is marketed by Eisai Co. under the tradename Halaven.

Biosynthesis

While a producer organism for Halichondrin B has never been isolated in pure culture, the structural features of Halichondrin B, such as the 'odd-even' rule of methylation, and the abundance of oxygen heterocycles, suggest it is a product of dinoflagellate polyether metabolism. [9] In support of this conjecture, the known dinoflagellate toxin okadaic acid was isolated from the same species of sponge. [10]

Okadaic acid, C44H68O13, is a toxin produced by several species of dinoflagellates, and is known to accumulate in both marine sponges and shellfish.

A polyketide, polyether derivative of a C38 fatty acid, okadaic acid and other members of its family have shined light upon many biological processes both with respect to dinoflagellete polyketide synthesis as well as the role of protein phosphatases in cell growth.

Agelasines are 7,9-dialkylpurinium salts isolated from marine sponges. They are considered secondary metabolites. Their contribution to the sponge is assumed to be some sort of protection against microorganisms. At the present time a total of eleven 9-methyladeninium salts, agelasine A–I, epiagelasine C and agelin B, are known. All compounds carry a diterpenoid side chain in the adenine 7-position. The agelasines are closely related in structure with the agelasimines.

<span class="mw-page-title-main">Taxane</span> Chemical compound

Taxanes are a class of diterpenes. They were originally identified from plants of the genus Taxus (yews), and feature a taxadiene core. Paclitaxel (Taxol) and docetaxel (Taxotere) are widely used as chemotherapy agents. Cabazitaxel was FDA approved to treat hormone-refractory prostate cancer.

This marine natural product is produced by the obligate marine bacteria Salinispora tropica and Salinispora arenicola, which are found in ocean sediment. Salinosporamide A belongs to a family of compounds, known collectively as salinosporamides, which possess a densely functionalized γ-lactam-β-lactone bicyclic core.

<span class="mw-page-title-main">Mitotic inhibitor</span> Cell division inhibitor

A mitotic inhibitor, microtubule inhibitor, or tubulin inhibitor, is a drug that inhibits mitosis, or cell division, and is used in treating cancer, gout, and nail fungus. These drugs disrupt microtubules, which are structures that pull the chromosomes apart when a cell divides. Mitotic inhibitors are used in cancer treatment, because cancer cells are able to grow through continuous division that eventually spread through the body (metastasize). Thus, cancer cells are more sensitive to inhibition of mitosis than normal cells. Mitotic inhibitors are also used in cytogenetics, where they stop cell division at a stage where chromosomes can be easily examined.

<span class="mw-page-title-main">Taccalonolide</span>

Taccalonolides are a class of microtubule-stabilizing agents isolated from Tacca chantrieri that has been shown to have selective cancer-fighting properties. Other examples of microtubule-stabilizing agents include taxanes and epothilones, both of which prevent cancer cells from dividing by interfering with tubulin. While taxanes like Paclitaxel and docetaxel have been used successfully against breast, ovarian, prostate, and non–small-cell lung cancers, intrinsic and acquired drug resistance limit their anticancer properties. Unlike taxanes, taccalonolides appear to work through a different mechanism of action that does not involve tubulin, although recently isolated taccalonolides AF and AJ have shown tubulin-interaction activity. The discovery of taccalonolides opens up new possibilities to treat cancer cells, especially ones that are taxane or epithilone resistant.

<span class="mw-page-title-main">Halicylindramide</span> Chemical compound

Halicylindramides are a group of antifungal peptides. The first compounds of this type, designated halicylindramides A through E, were isolated from sea sponges of the genus Halichondria. More compounds in the family, designated F, G and H, were found in sponges of the genus Petrosia. Halicylindramide A has been synthesized by chemists.

<span class="mw-page-title-main">Sponge isolates</span>

Lacking an immune system, protective shell, or mobility, sponges have developed an ability to synthesize a variety of unusual compounds for survival. C-nucleosides isolated from Caribbean Cryptotethya crypta, were the basis for the synthesis of zidovudine (AZT), aciclovir (Cyclovir), cytarabine (Depocyt), and cytarabine derivative gemcitabine (Gemzar).

The asymmetric addition of alkynylzinc compounds to aldehydes is an example of a Nef synthesis, a chemical reaction whereby a chiral propargyl alcohol is prepared from a terminal alkyne and an aldehyde. This alkynylation reaction is enantioselective and involves an alkynylzinc reagent rather than the sodium acetylide used by John Ulric Nef in his 1899 report of the synthetic approach. Propargyl alcohols are versatile precursors for the chirally-selective synthesis of natural products and pharmaceutical agents, making this asymmetric addition reaction of alkynylzinc compounds useful. For example, Erick Carreira used this approach in a total synthesis of the marine natural product leucascandrolide A, a bioactive metabolite of the calcareous sponge Leucascandra caveolata with cytotoxic and antifungal properties isolated in 1996.

<span class="mw-page-title-main">Onnamide A</span> Chemical compound

Onnamide A is a bioactive natural product found in Theonella swinhoei, a species of marine sponge whose genus is well known for yielding a diverse set of biologically active natural products, including the swinholides and polytheonamides. It bears structural similarities to the pederins, a family of compounds known to inhibit protein synthesis in eukaryotic cells. Onnamide A and its analogues have attracted academic interest due to their cytotoxicity and potential for combating the growth and proliferation of cancer cells.
