Alpha-glucosidase inhibitory constituents from Cuscuta reflexa. (1/21)
Two new compounds, 7'-(3',4'-dihydroxyphenyl)-N-[(4-methoxyphenyl)ethyl]propenamide (4), and 7'-(4'-hydroxy,3'-methoxyphenyl)-N-[(4-butylphenyl)ethyl]propenamide (5) have been isolated from Cuscuta reflexa along with five known compounds, 6,7-dimethoxy-2H-1-benzopyran-2-one (1), 3-(3,4-dihydroxyphenyl)-2-propen-1-ethanoate (2), 6,7,8-trimethoxy-2H-1-benzopyran-2-one (3), 3-(4-O-beta-D-glucopyranoside-3,5-dimethoxyphenyl)-2-propen-1-ol (6), 2-(3-hydroxy-4-methoxyphenyl)-3,5-dihydroxy-7-O-beta-D-glucopyranoside-4H-1-benzo pyrane-4-one (7), reported for the first time from this species. Structures of these compounds were determined by spectral analysis. These compounds showed strong inhibitory activity against alpha-glucosidase. (+info)Signal transduction controlling the blue- and red-light mediated gene expression of S-adenosylmethionine decarboxylase in Pharbitis nil. (2/21)
The signal transduction processes involved in the regulation of SAMDC gene expression by blue and red light were examined using pharmacological inhibitors of signalling pathways. Calcium and calmodulin positively regulated SAMDC gene expression in red light, whereas in blue light they regulated negatively. These results indicate that calcium homeostasis is involved in both red and blue light induction of SAMDC expression. Both signal transduction pathways also require new protein synthesis. (+info)Immunohistochemistry of active gibberellins and gibberellin-inducible alpha-amylase in developing seeds of morning glory. (3/21)
Gibberellins (GAs) in developing seeds of morning glory (Pharbitis nil) were quantified and localized by immunostaining. The starch grains began to be digested after the GA contents had increased and reached a plateau. Immunohistochemical staining with the antigibberellin A(1)-methyl ester-antiserum, which has high affinity to biologically active GAs, showed that GA(1) and/or GA(3) were localized around starch grains in the integument of developing young seeds, suggesting the participation of GA-inducible alpha-amylase in this digestion. We isolated an alpha-amylase cDNA (PnAmy1) that was expressed in the immature seeds, and using an antibody raised against recombinant protein, it was shown that PnAmy1 was expressed in the immature seeds. GA responsiveness of PnAmy1 was shown by treating the young fruits 9 d after anthesis with GA(3). RNA-blot and immunoblot analyses showed that PnAmy1 emerged soon after the rapid increase of GA(1/3). An immunohistochemical analysis of PnAmy1 showed that it, like the seed GA(1/3), was also localized around starch grains in the integument of developing young seeds. The localization of GA(1/3) in the integument coincident with the expression of PnAmy1 suggests that both function as part of a process to release sugars for translocation or for the further development of the seeds. (+info)Dodder infection induces the expression of a pathogenesis-related gene of the family PR-10 in alfalfa. (4/21)
A full-length cDNA, PPRG2, representing a gene highly expressed in dodder (Cuscuta trifolii Bab et. Gibs)-infected alfalfa (Medicago sativa L.) stems was isolated by differential screening. The predicted protein contains 157 amino acids and belongs to the PR-10 family of the pathogenesis-related genes with putative ribonuclease activities. Northern hybridizations showed that PPRG2 is transcribed in root and crops of uninfected alfalfa and is induced not only by dodder attack but also by bacterial infections and a large variety of environmental stresses. (+info)Candida leandrae sp. nov., an asexual ascomycetous yeast species isolated from tropical plants. (5/21)
The novel yeast species Candida leandrae is described based on eight isolates from decaying fruits of Leandra reversa Cogn. (Melastomataceae) in an Atlantic rainforest site in Brazil, one from a Convolvulaceae flower in Costa Rica and one from a drosophilid in Hawai'i. The strains differed in their colony morphology, one being butyrous and smooth and the other being filamentous and rugose. Sequences of the D1/D2 domains of the large-subunit rRNA gene from both morphotypes were identical. C. leandrae belongs to the Kodamaea clade and is closely related to Candida restingae. The two species can be separated on the basis of growth at 37 degrees C and the assimilation of melezitose, negative in the novel species. The type culture of C. leandrae is strain UNESP 00-64R(T) (=CBS 9735(T)=NRRL Y-27757(T)). (+info)Structures of new flavonoids, erycibenins D, E, and F, and NO production inhibitors from Erycibe expansa originating in Thailand. (6/21)
A new flavanol, erycibenin D, and two new flavans, erycibenins E and F, were isolated from the stems of Erycibe expansa originating in Thailand. The structures of new flavonoids were elucidated on the basis of chemical and physicochemical evidence. In addition, the inhibitory activities of the isolated constituents from E. expansa on lipopolysaccharide-activated nitric oxide production in mouse peritoneal macrophages were examined. Among the principal constituents, two isoflavones, clycosin (IC50 = 13 microM) and erythrinin B (18 microM), and two rotenoids, deguelin (26 microM) and rotenone (27 microM), were found to show potent inhibitory activity. (+info)Anti-stress constituents of Evolvulus alsinoides: an ayurvedic crude drug. (7/21)
Bioactivity-guided purification of n-BuOH soluble fraction from the ethanol extract of Evolvulus alsinoides resulted in the isolation of two new compounds, 2,3,4-trihydroxy-3-methylbutyl 3-[3-hydroxy-4-(2,3,4-trihydroxy-2-methylbutoxy)-phenyl]-2-propenoate (1) and 1,3-di-O-caffeoyl quinic acid methyl ester (2) along with six known compounds, caffeic acid (3), 6-methoxy-7-O-beta-glucopyranoside coumarin (4), 2-C-methyl erythritol (5), kaempferol-7-O-beta-glucopyranoside (6), kaempferol-3-O-beta-glucopyranoside (7) and quecetine-3-O-beta-glucopyranoside (8). The structure of new compounds 1 and 2 were elucidated by spectroscopic analysis, while known compounds were confirmed by direct comparison of their NMR data with those reported in literature. This is the first report of the presence of phenolic constituents in Evolvulus alsinoides. The isolated compounds 1-5 and 8 were screened for anti-stress activity in acute stress induced biochemical changes in adult male Sprague-Dawley rats. Stress exposure has resulted in significant increase of plasma glucose, adrenal gland weight, plasma creatine kinase (CK), and corticosterone levels. Compound 1 displayed most promising antistress effect by normalizing hyperglycemia, plasma corticosterone, CK and adrenal hypertrophy, while compounds 2 and 3 were also effective in normalizing most of these stress parameters, however compounds 4, 5 and 8 were ineffective in normalizing these parameters. (+info)Systematics and plastid genome evolution of the cryptically photosynthetic parasitic plant genus Cuscuta (Convolvulaceae). (8/21)
BACKGROUND: The genus Cuscuta L. (Convolvulaceae), commonly known as dodders, are epiphytic vines that invade the stems of their host with haustorial feeding structures at the points of contact. Although they lack expanded leaves, some species are noticeably chlorophyllous, especially as seedlings and in maturing fruits. Some species are reported as crop pests of worldwide distribution, whereas others are extremely rare and have local distributions and apparent niche specificity. A strong phylogenetic framework for this large genus is essential to understand the interesting ecological, morphological and molecular phenomena that occur within these parasites in an evolutionary context. RESULTS: Here we present a well-supported phylogeny of Cuscuta using sequences of the nuclear ribosomal internal transcribed spacer and plastid rps2, rbcL and matK from representatives across most of the taxonomic diversity of the genus. We use the phylogeny to interpret morphological and plastid genome evolution within the genus. At least three currently recognized taxonomic sections are not monophyletic and subgenus Cuscuta is unequivocally paraphyletic. Plastid genes are extremely variable with regards to evolutionary constraint, with rbcL exhibiting even higher levels of purifying selection in Cuscuta than photosynthetic relatives. Nuclear genome size is highly variable within Cuscuta, particularly within subgenus Grammica, and in some cases may indicate the existence of cryptic species in this large clade of morphologically similar species. CONCLUSION: Some morphological characters traditionally used to define major taxonomic splits within Cuscuta are homoplastic and are of limited use in defining true evolutionary groups. Chloroplast genome evolution seems to have evolved in a punctuated fashion, with episodes of loss involving suites of genes or tRNAs followed by stabilization of gene content in major clades. Nearly all species of Cuscuta retain some photosynthetic ability, most likely for nutrient apportionment to their seeds, while complete loss of photosynthesis and possible loss of the entire chloroplast genome is limited to a single small clade of outcrossing species found primarily in western South America. (+info)Convolvulaceae is a family of flowering plants, also known as the bindweed or morning glory family. It includes both annual and perennial vines, herbs, and shrubs, with over 1,650 species spread across around 60 genera. The plants in this family are characterized by their twining stems and funnel-shaped flowers. Some of the well-known members of Convolvulaceae include the sweet potato (Ipomoea batatas), morning glory (Ipomoea spp.), and bindweed (Convolvulus spp.).
Many species in this family contain ergoline alkaloids, which can have hallucinogenic effects. Some indigenous cultures have used these plants for their psychoactive properties in religious or spiritual ceremonies. However, it's important to note that some of these alkaloids can be toxic and even fatal if ingested in large quantities.
In a medical context, certain species of Convolvulaceae may be relevant due to their potential toxicity or as weeds that can cause problems in agriculture. For example, field bindweed (Convolvulus arvensis) is a notorious agricultural weed that can reduce crop yields and increase the difficulty of farming.
"Ipomoea" is a botanical term that refers to a genus of plants in the morning glory family, Convolvulaceae. These plants are primarily found in tropical and warm temperate regions around the world. Some species of Ipomoea have medicinal uses, but it's important to note that 'Ipomoea' itself is not a medical term or concept.
For instance, one species, Ipomoea batatas, commonly known as sweet potato, has been used in traditional medicine for various purposes, such as treating wounds and gastrointestinal disorders. However, any medicinal use would refer to the specific plant or extract, not simply the genus name 'Ipomoea'.
As always, if you're considering using any plant or herb for medicinal purposes, it's crucial to consult with a healthcare provider first to ensure safety and efficacy.
Calystegia is a genus of perennial, twining plants in the bindweed family (Convolvulaceae). These plants are characterized by their large, funnel-shaped flowers that can be white, pink, or purple. They are commonly known as "morning glories" and are native to North America, Europe, and Asia. Some common species of Calystegia include C. sepium (hedge bindweed), C. silvatica (woodland bindweed), and C. spithamaea (marsh bindweed).
It is worth noting that while the term "calystegia" refers to a specific genus of plants, it is not a medical term and does not have a specific definition in the context of medicine.
'Cuscuta' is a genus of parasitic plants in the morning glory family, Convolvulaceae. Commonly known as dodder, these plants have reduced leaves and stems that are twining tendrils, which coil around the stems of other plants to draw nutrients from them. Cuscuta species can cause significant damage to crops and are considered pests in agriculture.
In a medical context, 'Cuscuta' is not commonly used as a term. However, some species of Cuscuta have been used in traditional medicine in various parts of the world. For example, Cuscuta chinensis and Cuscuta europaea are sometimes used in Traditional Chinese Medicine (TCM) for their supposed benefits to the kidneys, liver, and eyesight. However, it is important to note that the scientific evidence supporting these claims is limited, and more research is needed before any firm conclusions can be drawn about their safety and efficacy as medical treatments.
In a medical context, "resins, plant" refer to the sticky, often aromatic substances produced by certain plants. These resins are typically composed of a mixture of volatile oils, terpenes, and rosin acids. They may be present in various parts of the plant, including leaves, stems, and roots, and are often found in specialized structures such as glands or ducts.
Plant resins have been used for centuries in traditional medicine and other applications. Some resins have antimicrobial, anti-inflammatory, or analgesic properties and have been used to treat a variety of ailments, including skin conditions, respiratory infections, and pain.
Examples of plant resins with medicinal uses include:
* Frankincense (Boswellia spp.) resin has been used in traditional medicine to treat inflammation, arthritis, and asthma.
* Myrrh (Commiphora spp.) resin has been used as an antiseptic, astringent, and anti-inflammatory agent.
* Pine resin has been used topically for its antimicrobial and anti-inflammatory properties.
It's important to note that while some plant resins have demonstrated medicinal benefits, they should be used with caution and under the guidance of a healthcare professional. Some resins can have adverse effects or interact with medications, and it's essential to ensure their safe and effective use.
In the context of medical terminology, "germination" is not typically used as a term to describe a physiological process in humans or animals. It is primarily used in the field of botany to refer to the process by which a seed or spore sprouts and begins to grow into a new plant.
However, if you are referring to the concept of germination in the context of bacterial or viral growth, then it could be defined as:
The process by which bacteria, viruses, or other microorganisms become active and start to multiply, often after a period of dormancy or latency. This can occur when the microorganisms encounter favorable conditions, such as moisture, warmth, or nutrients, that allow them to grow and reproduce. In medical contexts, this term is more commonly used in relation to infectious diseases caused by these microorganisms.
In medical terms, "seeds" are often referred to as a small amount of a substance, such as a radioactive material or drug, that is inserted into a tissue or placed inside a capsule for the purpose of treating a medical condition. This can include procedures like brachytherapy, where seeds containing radioactive materials are used in the treatment of cancer to kill cancer cells and shrink tumors. Similarly, in some forms of drug delivery, seeds containing medication can be used to gradually release the drug into the body over an extended period of time.
It's important to note that "seeds" have different meanings and applications depending on the medical context. In other cases, "seeds" may simply refer to small particles or structures found in the body, such as those present in the eye's retina.
Glycosides are organic compounds that consist of a glycone (a sugar component) linked to a non-sugar component, known as an aglycone, via a glycosidic bond. They can be found in various plants, microorganisms, and some animals. Depending on the nature of the aglycone, glycosides can be classified into different types, such as anthraquinone glycosides, cardiac glycosides, and saponin glycosides.
These compounds have diverse biological activities and pharmacological effects. For instance:
* Cardiac glycosides, like digoxin and digitoxin, are used in the treatment of heart failure and certain cardiac arrhythmias due to their positive inotropic (contractility-enhancing) and negative chronotropic (heart rate-slowing) effects on the heart.
* Saponin glycosides have potent detergent properties and can cause hemolysis (rupture of red blood cells). They are used in various industries, including cosmetics and food processing, and have potential applications in drug delivery systems.
* Some glycosides, like amygdalin found in apricot kernels and bitter almonds, can release cyanide upon hydrolysis, making them potentially toxic.
It is important to note that while some glycosides have therapeutic uses, others can be harmful or even lethal if ingested or otherwise introduced into the body in large quantities.
