Horsfiline
Horsfiline is an oxindole alkaloid found in the plant '' Horsfieldia superba'', which is used in traditional herbal medicine. It has analgesic effects and has been the subject of research both to produce it synthetically by convenient routes and to develop analogues and derivatives which may have improved analgesic effects. It is a member of the spiroindolone The spiroindolones are a class of compounds in which an indolone ring is substituted with another ring in a spiro arrangement. Alkaloids in this class include horsfiline, rhynchophylline, gelsemine, carapanaubine, and maremycin E. Spiroind ... class. Elacomine has a similar chemical structure.

Spiroindolone
The spiroindolones are a class of compounds in which an indolone ring is substituted with another ring in a spiro arrangement. Alkaloids in this class include horsfiline, rhynchophylline, gelsemine, carapanaubine, and maremycin E. Spiroindolones are also an emerging class of antimalarial drugs whose mode of action is to inhibit protein synthesis in the target parasite. The most advanced compound in this class in terms of drug development Drug development is the process of bringing a new pharmaceutical drug to the market once a lead compound has been identified through the process of drug discovery. It includes preclinical research on microorganisms and animals, filing for regu ... is cipargamin (NITD609). References Antimalarial agents Spiro compounds {{antiinfective-drug-stub ...

Horsfieldia Superba
''Horsfieldia'' is a genus of evergreen trees. The genus consists of about 100 species and is distributed across South Asia, from India to the Philippines and Papua New Guinea. Some species are used for timber. Species in the genus sometimes contain alkaloids, including horsfiline, which has analgesic effects.

Alkaloid
Alkaloids are a broad class of natural product, naturally occurring organic compounds that contain at least one nitrogen atom. Some synthetic compounds of similar structure may also be termed alkaloids. Alkaloids are produced by a large variety of organisms including bacteria, fungus, fungi, Medicinal plant, plants, and animals. They can be purified from crude extracts of these organisms by acid-base extraction, or solvent extractions followed by silica-gel column chromatography. Alkaloids have a wide range of pharmacology, pharmacological activities including antimalarial medication, antimalarial (e.g. quinine), asthma, antiasthma (e.g. ephedrine), chemotherapy, anticancer (e.g. omacetaxine mepesuccinate, homoharringtonine), cholinomimetic (e.g. galantamine), vasodilation, vasodilatory (e.g. vincamine), Antiarrhythmic agent, antiarrhythmic (e.g. quinidine), analgesic (e.g. morphine), antibacterial (e.g. chelerythrine), and anti-diabetic, antihyperglycemic activities (e.g. berb ...

Herbal Medicine
Herbal medicine (also called herbalism, phytomedicine or phytotherapy) is the study of pharmacognosy and the use of medicinal plants, which are a basis of traditional medicine. Scientific evidence for the effectiveness of many herbal treatments remains limited, prompting ongoing regulatory evaluation and research into their safety and efficacy. Standards for purity or dosage are generally not provided. The scope of herbal medicine sometimes includes fungal and bee products, as well as minerals, shells and certain animal parts. Paraherbalism is the pseudoscientific use of plant or animal extracts as medicine, relying on unproven beliefs about the safety and effectiveness of minimally processed natural substances. Herbal medicine has been used since at least the Paleolithic era, with written records from ancient Sumer, Egypt, Greece, China, and India documenting its development and application over millennia. Modern herbal medicine is widely used globally—especially in Asia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Analgesic
An analgesic drug, also called simply an analgesic, antalgic, pain reliever, or painkiller, is any member of the group of drugs used for pain management. Analgesics are conceptually distinct from anesthetics, which temporarily reduce, and in some instances eliminate, sensation, although analgesia and anesthesia are neurophysiologically overlapping and thus various drugs have both analgesic and anesthetic effects. Analgesic choice is also determined by the type of pain: For neuropathic pain, recent research has suggested that classes of drugs that are not normally considered analgesics, such as tricyclic antidepressants and anticonvulsants may be considered as an alternative. Various analgesics, such as many NSAIDs, are available over the counter in most countries, whereas various others are prescription drugs owing to the substantial risks and high chances of overdose, misuse, and addiction in the absence of medical supervision.

A European Journal
A, or a, is the first letter and the first vowel letter of the Latin alphabet, used in the modern English alphabet, and others worldwide. Its name in English is '' a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version is often written in one of two forms: the double-storey and single-storey . The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English, '' a'' is the indefinite article, with the alternative form ''an''. Name In English, the name of the letter is the ''long A'' sound, pronounced . Its name in most other languages matches the letter's pronunciation in open syllables. History The earliest known ancestor of A is ''aleph''—the first letter of the Phoenician ...
