Anti-leishmanial activity of alkaloidal extract from Aspidosperma ramiflorum. (1/18)

Infections due to protozoa of the genus Leishmania are a major worldwide health problem, with high endemicity in developing countries. The drugs of choice for the treatment of leishmaniasis are the pentavalent antimonials (SbV), which present renal and cardiac toxicity. Besides, the precise chemical structure and mechanism of action of these drugs are unknown up to date. In order to find new drugs against leishmaniasis, we have been studying extracts of Brazilian trees. In the present study, we have evaluated the effectiveness of an alkaloid extract of Aspidosperma ramiflorum Muell. Arg. (Apocynaceae), against the extracellular forms promastigotes of L. (L.) amazonensis and L. (V.) braziliensis. The alkaloid extract of A. ramiflorum was much more effective against L. (L.) amazonensis (LD50 < 47 microg/ml) than L. (V.) braziliensis. Based on these in vitro results against L. (L.) amazonensis new studies should be made to find the compounds with anti-leishmanial activity.  (+info)

Revisiting a classic approach to the Aspidosperma alkaloids: an intramolecular Schmidt reaction mediated synthesis of (+)-aspidospermidine. (2/18)

[reaction: see text] A total synthesis of (+)-aspidospermidine (1) is described. The key reactions used in the synthesis of this pentacyclic Aspidosperma alkaloid were a deracemizing imine alkylation/Robinson annulation sequence, a selective "redox ketalization", and an intramolecular Schmidt reaction. A Fischer indolization step carried out on a tricyclic ketone mirrored the sequence reported by Stork and Dolfini in their classic aspidospermine synthesis.  (+info)

Antibacterial activity of indole alkaloids from Aspidosperma ramiflorum. (3/18)

We evaluated the antibacterial activities of the crude methanol extract, fractions (I-V) obtained after acid-base extraction and pure compounds from the stem bark of Aspidosperma ramiflorum. The minimum inhibitory concentration (MIC) was determined by the microdilution technique in Mueller-Hinton broth. Inoculates were prepared in this medium from 24-h broth cultures of bacteria (10(7) CFU/mL). Microtiter plates were incubated at 37 masculineC and the MICs were recorded after 24 h of incubation. Two susceptibility endpoints were recorded for each isolate. The crude methanol extract presented moderate activity against the Gram-positive bacteria B. subtilis (MIC = 250 microg/mL) and S. aureus (MIC = 500 microg/mL), and was inactive against the Gram-negative bacteria E. coli and P. aeruginosa (MIC > 1000 microg/mL). Fractions I and II were inactive against standard strains at concentrations of < or =1000 microg/mL and fraction III displayed moderate antibacterial activity against B. subtilis (MIC = 500 microg/mL) and S. aureus (MIC = 250 microg/mL). Fraction IV showed high activity against B. subtilis and S. aureus (MIC = 15.6 microg/mL) and moderate activity against E. coli and P. aeruginosa (MIC = 250 microg/mL). Fraction V presented high activity against B. subtilis (MIC = 15.6 microg/mL) and S. aureus (MIC = 31.3 microg/mL) and was inactive against Gram-negative bacteria (MIC > 1000 microg/mL). Fractions III, IV and V were then submitted to bioassay-guided fractionation by silica gel column chromatography, yielding individual purified ramiflorines A and B. Both ramiflorines showed significant activity against S. aureus (MIC = 25 microg/mL) and E. faecalis (MIC = 50 microg/mL), with EC50 of 8 and 2.5 microg/mL for ramiflorines A and B, respectively, against S. aureus. These results are promising, showing that these compounds are biologically active against Gram-positive bacteria.  (+info)

Formal synthesis of aspidosperma alkaloids via the intramolecular [3 + 2] cycloaddition of 2-azapentdienyllithiums. (4/18)

[reaction: see text] A formal synthesis of the Aspidosperma alkaloids aspidospermidine, aspidospermine, and quebrachamine is reported through an efficient preparation of Stork's penultimate intermediate. The key step of the sequence involved an intramolecular [3 + 2] cycloaddition of the 2-azapentadienyllithium 21 formed in situ from the corresponding imine 1, which after N-alkylation of the resulting cycloadduct provided 2 in excellent yield. The synthesis represents a new disconnection of the classical tricyclic ketone used for appendage of the requisite indole.  (+info)

Application of the Rh(II) cyclization/cycloaddition cascade for the total synthesis of (+/-)-aspidophytine. (5/18)

[Structure: see text] A new strategy for the synthesis of (+/-)-aspidophytine has been developed and is based on a Rh(II)-catalyzed cyclization/dipolar cycloaddition sequence. The resulting [3+2]-cycloadduct undergoes an efficient Lewis acid mediated cascade that rapidly provides the complete skeleton of aspidophytine. The synthesis also features a mild decarbomethoxylation reaction.  (+info)

Toward general access to the aspidosperma-type terpenoid indole alkaloids: synthesis of the key 3,3-disubstituted piperidones through enantioselective intramolecular heck-type reaction of chloroformamides. (6/18)

An enantioselective intramolecular Heck-type reaction of chloroformamides has been developed for the synthesis of 3,3-disubstituted piperidones. The desired piperidone was formed in the presence of a palladium catalyst, an optically active phosphoramidite ligand, K3PO4 and Ag3PO4. The obtained piperidone was converted to epieburnamonine.  (+info)

Itaipu goes beyond the reforestation of previously existing woodlands around the lake. The power plant also produces the seedlings to be planted.. Of the 23 million seedlings already planted on the lakes protection strip, 14 million came from the three forest nurseries operated by the company in the cities of Foz do Iguaçu, Santa Helena and Guaíra.. Today, the two Foz do Iguaçu and Santa Helena nurseries work in collaboration with the Western Paraná State University (Universidade Estadual do Oeste do Paraná - Unioeste).. Itaipu nurseries develop seedlings of 75 native tree species, especially peroba (Aspidosperma polyneuron), lapacho (Tabebuia. avellanedae), cedar (Cedrela fissilis), pau-marfim (Balfourodendron riedelianum) and yellow poinciana (Peltophorum dubium).. A program developed by Itaipu to prevent incest among trees allows the company to produce high-quality seeds characterized by what scientists call high degree of genetic variability.. These seeds are the result of ...
Note that this is just one of the many ways that ATP is used as a energy storage unit: in order to make a high energy acyl phosphate molecule from a low energy carboxylate, the cell must spend the energy of one ATP molecule.. An excellent example of biological activated carboxylic acids is seed in the biosynthesis of fatty acids. In the biologically active form of fatty acids, the carboxylate groups have been converted to thioesters using coenzyme A. For example, the activated form of the C16 fatty acid palmitate is:. ...

Chondrodendron tomentosum undergoes sexual reproduction like other flowering plants. It is a dioecious plant, meaning it has male and female flowers. The plant produces sperm, which is what most of us call pollen, and is distributed by wind and animals to other plants. The sperm then has to unite with an egg inside the stigma of the plant. A seed is produced from the fertilized egg, and this then germinates once in the ground. The germinating seed then continues to grow into the adult plant and the process repeats itself. The diagram below shows the cycle. The ovary of the Chondrodendron tomentosum is quite underdeveloped compared to the other flowering plants. It is a primitive plant with the other Ranunculales plants.. ...
The Schmidt reaction is an organic reaction in which an azide reacts with a carbonyl group to give an amine or amide, with expulsion of nitrogen. It is named after Karl Friedrich Schmidt (1887-1971), who first reported it in 1924 by successfully converting benzophenone and hydrazoic acid to benzanilide. Surprisingly, the intramolecular reaction wasnt reported until 1991 but has become important in the synthesis of natural products The carboxylic acid Schmidt reaction starts with acylium ion 1 obtained from protonation and loss of water. Reaction with hydrazoic acid forms the protonated azido ketone 2, which goes through a rearrangement reaction with the alkyl group R, migrating over the C-N bond with expulsion of nitrogen. The protonated isocyanate is attacked by water forming carbamate 4, which after deprotonation loses carbon dioxide to the amine. The reaction is related to the Curtius rearrangement except that in this reaction the azide is protonated and hence with different intermediates. ...

Quebracho (also known as Luciano malo) is a common name in Spanish to describe very hard (density 1.15 - 1.35) wood tree species. The etymology of the name derived from quiebrahacha, or quebrar hacha, meaning axe-breaker. There are at least three similar commercially important tree species that grow in the Gran Chaco region of South America. the red quebracho Schinopsis lorentzii (the red quebracho), of the family Anacardiaceae Schinopsis balansae (the willow-leaf red quebracho), of the same family the white quebracho or Aspidosperma quebracho-blanco of the family Apocynaceae A fourth species, Jodina rhombifolia (syn. Iodinia rhombifolia, the Quebracho flojo (the loose quebracho) or quebrachillo) of the family Santalaceae, is also sometimes mentioned. These species provide tannin and a very hard, durable timber. Quebracho is sometimes used as a commercial name for the tannin derived from the trees or their timber. Other species with less economical significance are also locally known as ...
p-Menthane-3-carboxaldehyde is a readily available chiral auxiliary used to prepare cycloalkenes and heterocycles bearing a chiral tertiary or quaternary carbon of high enantiomeric purity. The auxiliary is available in both enantiomeric forms and is inexpensive and recyclable. It is cleaved by a ring-closing alkene metathesis reaction directly yielding the cycloalkene.Key words: chiral auxiliary, cleavage reaction, cyclization, ring-closing alkene metathesis, enantioenriched cycloalkenes.
The second alkene metathesis step was the coupling of 12 with 13. The most effective catalyst in this case was the second generation Grubbs. Note that the free alcohol 13 participated successfully in the cross-coupling. According to the authors, this is one of just a few examples of successful cross coupling of an alkene adjacent to a quaternary center.. The stereocontrolled construction of trisubstituted alkenes by metathesis is a particular challenge. In his synthesis (Org. Lett. 2007, 9, 2585. ) of amphidinolide Y (21), a modestly cytotoxic macrolide antibiotic, Wei-Min Dai of Zhejian University and the Hong Kong University of Science and Technology took up this challenge. The substrate for cyclization was prepared by coupling the acid 15 with the alcohol 16, followed by selective deprotection and oxidation. Medium-ring conformational effects played an important role in this metathesis. The cyclization was also attempted with the TES ethers of the two diastereomeric secondary alcohols ...
The approaches to immobilization of metal-complex catalysts for organic processes of hydrogenation, alkene metathesis, and cross-coupling on silica and polymeric and other carriers are considered. The advantages and lack of modern approaches to the creation of such systems are analyzed. It was shown that the stability of the catalyst with immobilized metal complex in the respective process was directly related to the mechanism of its catalytic action, namely, ligand cleavage in the catalytic cycle. Among the considered catalysts for various types of reactions, the catalysts for hydrogenation processes had the highest stability; this peculiarity is associated with specific features of their action.. ...
