Perophora namei is a sea squirt species in the genus Perophora found in Central Indo-Pacific.
Perophora namei produces the alkaloid perophoramidine. [1]
Alkaloids are a class of basic, naturally occurring organic compounds that contain at least one nitrogen atom. This group also includes some related compounds with neutral and even weakly acidic properties. Some synthetic compounds of similar structure may also be termed alkaloids. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen or sulfur. Rarer still, they may contain elements such as phosphorus, chlorine, and bromine.
Convolvulaceae, commonly called the bindweeds or morning glories, is a family of about 60 genera and more than 1,650 species. These species are primarily herbaceous vines, but also include trees, shrubs and herbs. The tubers of several species are edible, the best known of which is the sweet potato.
Ergoline is a chemical compound whose structural skeleton is contained in a variety of alkaloids, referred to as ergoline derivatives or ergoline alkaloids. Ergoline alkaloids, one being ergine, were initially characterized in ergot. Some of these are implicated in the condition ergotism, which can take a convulsive form or a gangrenous form. Even so, many ergoline alkaloids have been found to be clinically useful. Annual world production of ergot alkaloids has been estimated at 5,000–8,000 kg of all ergopeptines and 10,000–15,000 kg of lysergic acid, used primarily in the manufacture of semi-synthetic derivatives.
Mandragora officinarum is the type species of the plant genus Mandragora in the nightshade family Solanaceae. It is often known as mandrake, although this name is also used for other plants. As of 2015, sources differed significantly in the species they use for Mandragora plants native to the Mediterranean region. The main species found around the Mediterranean is called Mandragora autumnalis, the autumn mandrake. In a broader circumscription, all the plants native to the regions around the Mediterranean Sea are placed in M. officinarum, which thus includes M. autumnalis. The names autumn mandrake and Mediterranean mandrake are then used. Whatever the circumscription, Mandragora officinarum is a perennial herbaceous plant with ovate leaves arranged in a rosette, a thick upright root, often branched, and bell-shaped flowers followed by yellow or orange berries.
Phlebobranchia is an order of sea squirts in the class Ascidiacea, first described by Fernando Lahille in 1886.
Erythravine is a tetrahydroisoquinoline alkaloid found in the plant Erythrina mulungu and other species of the genus Erythrina.
Hodgkinsine is an alkaloid found in plants of the genus Psychotria, particularly Psychotria colorata, although it is also found in Psychotria lyciiflora and probably other species in this family,
Rhynchophylline is an alkaloid found in certain Uncaria species (Rubiaceae), notably Uncaria rhynchophylla and Uncaria tomentosa. It also occurs in the leaves of Mitragyna speciosa (kratom) and Mitragyna tubulosa, a tree native to Thailand. Chemically, it is related to the alkaloid mitragynine.
Conessine is a steroidal alkaloid found in a number of plant species from the family Apocynaceae, including Holarrhena floribunda, Holarrhena antidysenterica and Funtumia elastica. It acts as a histamine antagonist, selective for the H3 subtype (with an affinity of pKi = 8.27; Ki = ~5 nM). It was also found to have long CNS clearance times, high blood–brain barrier penetration and high affinity for the adrenergic receptors.
Coronaridine, also known as 18-carbomethoxyibogamine, is an alkaloid found in Tabernanthe iboga and related species, including Tabernaemontana divaricata for which it was named.
Ibogamine is an anti-convulsant, anti-addictive, CNS stimulant alkaloid found in Tabernanthe iboga and Crepe Jasmine. Basic research related to how addiction affects the brain has used this chemical.
Perophora is a sea squirt genus in the family Perophoridae. Most species are found in shallow warm water but a few are found in higher latitudes. A colony consists of a number of zooids which bud off from a long slender stolon.
Perophora viridis, the honeysuckle tunicate, is a species of colonial sea squirt in the genus Perophora found in the tropical western Atlantic Ocean.
Akuammicine is a monoterpene indole alkaloid of the Vinca sub-group. It is found in the Apocynaceae family of plants including Picralima nitida, Vinca minor and the Aspidosperma.
Amathia verticillata, commonly known as the spaghetti bryozoan, is a species of colonial bryozoans with a bush-like structure. It is found in shallow temperate and warm waters in the western Atlantic Ocean and the Caribbean Sea and has spread worldwide as a fouling organism. It is regarded as an invasive species in some countries.
Perophora multiclathrata is a species of colonial sea squirt in the genus Perophora. It is native to the tropical Indo-Pacific and the western Atlantic Ocean.
Dioscorine is an alkaloid toxin isolated from the tubers of tropical yam on several continents. It has been used as a monkey poison in some African countries, and as an arrow poison to aid in hunting in several parts of Asia. It was first isolated from Dioscorea hirsute by Boorsma in 1894 and obtained in a crystalline form by Schutte in 1897, and has since been found in other Dioscorea species. Dioscorine is a neurotoxin that acts by blocking the nicotinic acetylcholine receptor. Dioscorine is generally isolated in tandem with other alkaloids such as dioscin but is usually the most potent toxin in the mixture. It is a convulsant, producing symptoms similar to picrotoxin, with which it shares a similar mechanism of action.
The Solanaceae, or the nightshades, is a family of flowering plants that ranges from annual and perennial herbs to vines, lianas, epiphytes, shrubs, and trees, and includes a number of agricultural crops, medicinal plants, spices, weeds, and ornamentals. Many members of the family contain potent alkaloids, and some are highly toxic, but many—including tomatoes, potatoes, eggplant, bell, and chili peppers—are used as food. The family belongs to the order Solanales, in the asterid group and class Magnoliopsida (dicotyledons). The Solanaceae consists of about 98 genera and some 2,700 species, with a great diversity of habitats, morphology and ecology.
Apparicine is a monoterpenoid tricyclic indole alkaloid. It is named after Apparicio Duarte, a Brazilian botanist who studied the Aspidosperma species from which apparicine was first isolated. It was the first member of the vallesamine group of indole alkaloids to be isolated and have its structure established, which was first published in 1965. It has also been known by the synonyms gomezine, pericalline, and tabernoschizine.
Perophora listeri is a species of colonial sea squirt in the genus Perophora, native to the North Atlantic.
