Solasodamine
Solasonine is a glycoalkaloid that is found in Solanum plants of the family Solanaceae. Solasonine is a poisonous chemical compound when used at high levels. It is a glycoside of solasodine. Glycoalkaloids such as Solasonine have various applications including pharmacology, cancer treatments and even a role as a pesticide. High levels of glycoalkaloids are toxic to humans due to their ability to disrupt cell-membrane function. There is a loss of membrane integrity which puts the cell at risk for apoptosis (cell death) due to the ability of any chemical coming into contact with the cell. Solasonine was one component of the unsuccessful experimental cancer drug candidate Coramsine. Side Effects Although, solasonine has anti-infection properties it has many adverse side effects as a steroidal glycoalkaloid. These side effects include low blood pressure, a decrease in respiratory activity, rapid heart beat etc. These side effects are the direct result of the cytotoxic properties ...

Glycoalkaloid
Glycoalkaloids are a family of chemical compounds derived from alkaloids to which sugar groups are appended. Several are potentially toxic, most notably the poisons commonly found in the plant species ''Solanum dulcamara'' (bittersweet nightshade) and other plants in the genus ''Solanum'', including potato. A prototypical glycoalkaloid is solanine (composed of the sugar solanose and the alkaloid solanidine), which is found in the potato. The alkaloidal portion of the glycoalkaloid is also generically referred to as an aglycone. The intact glycoalkaloid is poorly absorbed from the human gastrointestinal tract, gastrointestinal tract but causes gastrointestinal irritation. The aglycone is absorbed and is believed to be responsible for observed nervous system signs. Glycoalkaloids are typically bitter (taste), bitter tasting, and produce a burning irritation in the back of the mouth and side of the tongue. The Aymara people of Bolivia use taste to detect the levels of glycoalkaloids ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solanaceae
The Solanaceae , or nightshades, are 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. The name Solanaceae derives from the genus ''Solanum''. The etymology of the Latin word is unclear. The name may come from a perceived resemblance of certain solanaceous flowers to the sun and its rays. At least one species of ''Solanum'' is known as the "sunberry". Alternatively, the name could originate from the Latin verb ''sol ...

Poisonous
Poison is a chemical substance that has a detrimental effect to life. The term is used in a wide range of scientific fields and industries, where it is often specifically defined. It may also be applied colloquially or figuratively, with a broad sense. Whether something is considered a poison may change depending on the amount, the circumstances, and what living things are present. Poisoning could be accidental or deliberate, and if the cause can be identified there may be ways to neutralise the effects or minimise the symptoms. In biology, a poison is a chemical substance causing death, injury or harm to organisms or their parts. In medicine, poisons are a kind of toxin that are delivered passively, not actively. In industry the term may be negative, something to be removed to make a thing safe, or positive, an agent to limit unwanted pests. In ecological terms, poisons introduced into the environment can later cause unwanted effects elsewhere, or in other parts of the food ...

Chemical Compound
A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) containing atoms from more than one chemical element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound. A compound can be transformed into a different substance by a chemical reaction, which may involve interactions with other substances. In this process, bonds between atoms may be broken and/or new bonds formed. There are four major types of compounds, distinguished by how the constituent atoms are bonded together. Molecular compounds are held together by covalent bonds; ionic compounds are held together by ionic bonds; intermetallic compounds are held together by metallic bonds; coordination complexes are held together by coordinate covalent bonds. Non-stoichiometric compounds form a disputed marginal case. A chemical formula specifies the number of atoms of each element in a compound molecule, using the s ...

Glycoside
In chemistry, a glycoside is a molecule in which a sugar is bound to another functional group via a glycosidic bond. Glycosides play numerous important roles in living organisms. Many plants store chemicals in the form of inactive glycosides. These can be activated by enzyme hydrolysis, which causes the sugar part to be broken off, making the chemical available for use. Many such plant glycosides are used as medications. Several species of ''Heliconius'' butterfly are capable of incorporating these plant compounds as a form of chemical defense against predators. In animals and humans, poisons are often bound to sugar molecules as part of their elimination from the body. In formal terms, a glycoside is any molecule in which a sugar group is bonded through its anomeric carbon to another group via a glycosidic bond. Glycosides can be linked by an O- (an ''O-glycoside''), N- (a ''glycosylamine''), S-(a ''thioglycoside''), or C- (a '' C-glycoside'') glycosidic bond. According to th ...

Solasodine
Solasodine is a poisonous alkaloid chemical compound that occurs in plants of the family Solanaceae such as potatoes and tomatoes. Solasonine and solamargine are glycoalkaloid derivatives of solasodine. Solasodine is teratogenic to hamster fetuses in a dose of 1200 to 1600 mg/kg. Literature survey reveals that solasodine has diuretic, anticancer, antifungal, cardiotonic, antispermatogenetic, antiandrogenic, immunomodulatory, antipyretic and various effects on central nervous system. Uses It is commercially used as a precursor for the production of complex steroidal compounds such as contraceptive pills, via a 16-DPA intermediate.

Coramsine
Coramsine (SBP002) was an experimental cancer drug that was evaluated in preliminary clinical trials, but was abandoned by Solbec Pharmaceuticals Ltd after the results were insufficient for them to raise investment capital to continue its development. Composition Coramsine is a chemotherapeutic and immunomodulating agent whose primary ingredients are two solasodine glycoalkaloids, solasonine and solamargine, which are derived from the plant ''Solanum linnaeanum'' (Devil's Apple). History The study of glycoalkaloids as potential anti-cancer agents began with Queensland researcher Bill Cham in the late 1970s. Cham heard reports from farmers that topical application of the Devil's Apple plant was effective in slowing the growth of various skin cancers on horses and cattle. Animal studies and ''in vitro'' studies showed positive results, however Cham decided to focus his energies on developing the glycoalkaloid mixture, patented as BEC, as a topical cream for non- melanoma skin can ...

Steroidal Alkaloids
Steroidal alkaloids have organic ring backbones which feature nitrogen-based functional groups. More specifically, they are distinguished by their tetracyclic cyclopentanophenanthrene backbone that marks their close relationship with sterols. They fall in two major categories: Solanum alkaloids and Veratrum alkaloids. A Steroidal alkaloid has also been found in ''Chonemorpha fragrans'' (Frangipani vine), 'chonemorphine' was used to treat intestinal infections in Wistar rats. (Chatterjee DK et al (1987) Parasitol Res 74, 1, 30-33). ''Solanum'' alkaloids These compounds generally appear as their corresponding glycoside in plants of the genus ''Solanum''. ''Solanum'' includes plants like potatoes, tomatoes, and various nightshades Starting with cholesterol, the biosynthesis of these compounds follow a similar general mechanism including hydroxylation, oxidation, and transamination before differentiating. Alkaloids found in these plants include chaconine, solanine, solasodine, tomat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alkaloid Glycosides
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, sulfur and, more rarely, other elements such as chlorine, bromine, and phosphorus.Chemical Encyclopedia: alkaloids xumuk.ru Alkaloids are produced by a large variety of organisms including , , |
Plant Toxins
A toxin is a naturally occurring organic poison produced by metabolic activities of living cells or organisms. Toxins occur especially as a protein or conjugated protein. The term toxin was first used by organic chemist Ludwig Brieger (1849–1919) and is derived from the word toxic. Toxins can be small molecules, peptides, or proteins that are capable of causing disease on contact with or absorption by body tissues interacting with biological macromolecules such as enzymes or cellular receptors. Toxins vary greatly in their toxicity, ranging from usually minor (such as a bee sting) to potentially fatal even at extremely low doses (such as botulinum toxin). Toxins are largely secondary metabolites, which are organic compounds that are not directly involved in an organism's growth, development, or reproduction, instead often aiding it in matters of defense. Terminology Toxins are often distinguished from other chemical agents strictly based on their biological origin. Less s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
