Discodermia dissoluta is a species of deep-water sea sponge found in the Eastern, Southern, and Southwestern Caribbean, as well as in the Greater Antilles. This sponge is of particular interest to bio and organic chemists due to its production of a potent chemical compound called (+)-discodermolide, which has potential therapeutic applications for cancer treatment. [2]

Contents

Description

D. dissoluta has a distinctive morphology, with a thick, smooth surface and a flattened, disc-shaped body that can grow up to 30 cm in diameter. The sponge's body is composed of a complex network of spicules and spongin fibers, which provide structural support and protection against predators.

Distribution and habitat

D. dissoluta is found in deep-water environments in the Caribbean, typically at depths ranging from 70 to 1,200 meters. It is commonly found on rocky substrates and coral reefs, where it may compete with other benthic organisms for space and resources.

Biochemical properties

D. dissoluta has garnered attention from the scientific community due to its production of (+)-discodermolide, a polyketide natural product with potent anticancer and immunosuppressive properties. [2] [3] (+)-Discodermolide was first isolated and characterized in 1990 by researchers at Harbor Branch Oceanographic Institution, who noted its remarkable structural complexity and unique mechanism of action.

The discovery of (+)-discodermolide sparked significant interest in the potential therapeutic applications of natural products derived from marine organisms, and led to extensive research into the biochemical properties and pharmacological effects of this compound.

Applications in cancer treatment

Studies have demonstrated that (+)-discodermolide exhibits potent cytotoxicity against a wide range of cancer cell lines, including those resistant to other chemotherapeutic agents. This has led to considerable interest in the development of (+)-discodermolide and related compounds as potential cancer therapies.

(+)-Discodermolide has also been found to have immunosuppressive properties, making it a potential candidate for use in transplant medicine and other applications. [3]

Conservation status

Due to its deep-water habitat and limited distribution, little is known about the population size or conservation status of Discodermia dissoluta. However, like many other marine organisms, it is threatened by human activities such as overfishing, pollution, and habitat destruction.

Research and conservation efforts

D. dissoluta is the subject of ongoing research into its biochemistry, ecology, and potential therapeutic applications. In addition, conservation efforts are underway to protect the species and its habitat from human impacts. These efforts include marine protected areas, sustainable fishing practices, and public outreach and education.

The Venus' flower basket is a glass sponge in the phylum Porifera. It is a marine sponge found in the deep waters of the Pacific ocean, usually at depths below 500 meters. Like other sponges, they feed by filtering sea water to capture plankton and marine snow. Similar to other glass sponges, they build their skeletons out of silica, which forms a unique lattice structure of spicules. The sponges are usually between 10 cm and 30 cm tall, and their bodies act as refuge for their mutualist shrimp partners. This body structure is of great interest in materials science as the optical and mechanical properties are in some ways superior to man-made materials. Little is known regarding their reproduction habits, however fluid dynamics of their body structure likely influence reproduction and it is hypothesized that they may be hermaphroditic.

<span class="mw-page-title-main">Natural product</span> Chemical compound or substance produced by a living organism, found in nature

A natural product is a natural compound or substance produced by a living organism—that is, found in nature. In the broadest sense, natural products include any substance produced by life. Natural products can also be prepared by chemical synthesis and have played a central role in the development of the field of organic chemistry by providing challenging synthetic targets. The term natural product has also been extended for commercial purposes to refer to cosmetics, dietary supplements, and foods produced from natural sources without added artificial ingredients.

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

(+)-Discodermolide is a polyketide natural product found to stabilize microtubules. (+)-discodermolide was isolated by Gunasekera and his co-workers at the Harbor Branch Oceanographic Institute from the deep-sea sponge Discodermia dissoluta in 1990. (+)-Discodermolide was found to be a potent inhibitor of tumor cell growth in several MDR cancer cell lines. (+)-discodermolide also shows some unique characters, including a linear backbone structure, immunosuppressive properties both in vitro and in vivo, potent induction of an accelerated senescence phenotype, and synergistic antiproliferative activity in combination with paclitaxel. Discodermolide was recognized as one of the most potent natural promoters of tubulin assembly. A large number of efforts toward the total synthesis of (+)-discodermolide were directed by its interesting biological activities and extreme scarcity of natural sources. The compound supply necessary for complete clinical trials cannot be met by harvesting, isolation, and purification. As of 2005, attempts at synthesis or semi-synthesis by fermentation have proven unsuccessful. As a result, all discodermolide used in preclinical studies and clinical trials has come from large-scale total synthesis.

The latrunculins are a family of natural products and toxins produced by certain sponges, including genus Latrunculia and Negombata, whence the name is derived. It binds actin monomers near the nucleotide binding cleft with 1:1 stoichiometry and prevents them from polymerizing. Administered in vivo, this effect results in disruption of the actin filaments of the cytoskeleton, and allows visualization of the corresponding changes made to the cellular processes. This property is similar to that of cytochalasin, but has a narrow effective concentration range. Latrunculin has been used to great effect in the discovery of cadherin distribution regulation and has potential medical applications. Latrunculin A, a type of the toxin, was found to be able to make reversible morphological changes to mammalian cells by disrupting the actin network.

Marine pharmacognosy is the investigation and identification of medically important plants and animals in the marine environment. It is a sub branch of terrestrial pharmacognosy. Generally the drugs are obtained from the marine species of bacteria, virus, algae, fungi and sponges. It is a relatively new field of study in western medicine, although many marine organisms were used in Traditional Chinese Medicine. It was not until 2004 that the first FDA approval of a drug came directly from the sea: ziconotide, which was isolated from a marine cone snail.

Sea sponge aquaculture is the process of farming sea sponges under controlled conditions. It has been conducted in the world's oceans for centuries using a number of aquaculture techniques. There are many factors such as light, salinity, pH, dissolved oxygen and the accumulation of waste products that influence the growth rate of sponges. The benefits of sea sponge aquaculture are realised as a result of its ease of establishment, minimum infrastructure requirements and the potential to be used as a source of income for populations living in developing countries. Sea sponges are produced on a commercial scale to be used as bath sponges or to extract biologically active compounds which are found in certain sponge species. Techniques such as the rope and mesh bag method are used to culture sponges independently or within an integrated multi-trophic aquaculture system setting. One of the only true sustainable sea sponges cultivated in the world occur in the region of Micronesia, with a number of growing and production methods used to ensure and maintain the continued sustainability of these farmed species.

Tubulin inhibitors are chemotherapy drugs that interfere directly with the tubulin system, which is in contrast to those chemotherapy drugs acting on DNA. Microtubules play an important role in eukaryotic cells. Alpha- and beta-tubulin, the main components of microtubules, have gained considerable interest because of their function and biophysical properties and has become the subject of intense study. The addition of tubulin ligands can affect microtubule stability and function, including mitosis, cell motion and intracellular organelle transport. Tubulin binding molecules have generated significant interest after the introduction of the taxanes into clinical oncology and the general use of the vinca alkaloids. These compounds inhibit cell mitosis by binding to the protein tubulin in the mitotic spindle and preventing polymerization or depolymerization into the microtubules. This mode of action is also shared with another natural agent called colchicine.

Tectitethya crypta is a species of demosponge belonging to the family Tethyidae. Its classified family is characterized by fourteen different known genera, one of them being Tectitethya. It is a massive, shallow-water sponge found in the Caribbean Sea. This sponge was first discovered by Werner Bergmann in 1945 and later classified by de Laubenfels in 1949. It is located in reef areas situated on softer substrates such as sand or mud. Oftentimes, it is covered in sand and algae. This results in an appearance that is cream colored/ gray colored; however, when the animal is washed free of its sediment coverings, its body plan appears more green and gray. It's characterized with ostia peaking out of its body cavity, with the ability to abruptly open or close, changing its desired water flow rate through its mesohyl.
