Protein synthesis by native chemical ligation: expanded scope by using straightforward methodology. (1/290)

The total chemical synthesis of proteins has great potential for increasing our understanding of the molecular basis of protein function. The introduction of native chemical ligation techniques to join unprotected peptides next to a cysteine residue has greatly facilitated the synthesis of proteins of moderate size. Here, we describe a straightforward methodology that has enabled us to rapidly analyze the compatibility of the native chemical ligation strategy for X-Cys ligation sites, where X is any of the 20 naturally occurring amino acids. The simplified methodology avoids the necessity of specific amino acid thioester linkers or alkylation of C-terminal thioacid peptides. Experiments using matrix-assisted laser-desorption ionization MS analysis of combinatorial ligations of LYRAX-C-terminal thioester peptides to the peptide CRANK show that all 20 amino acids are suitable for ligation, with Val, Ile, and Pro representing less favorable choices because of slow ligation rates. To illustrate the method's utility, two 124-aa proteins were manually synthesized by using a three-step, four-piece ligation to yield a fully active human secretory phospholipase A(2) and a catalytically inactive analog. The combination of flexibility in design with general access because of simplified methodology broadens the applicability and versatility of chemical protein synthesis.  (+info)

The missing organic molecules on Mars. (2/290)

GC-MS on the Viking 1976 Mars missions did not detect organic molecules on the Martian surface, even those expected from meteorite bombardment. This result suggested that the Martian regolith might hold a potent oxidant that converts all organic molecules to carbon dioxide rapidly relative to the rate at which they arrive. This conclusion is influencing the design of Mars missions. We reexamine this conclusion in light of what is known about the oxidation of organic compounds generally and the nature of organics likely to come to Mars via meteorite. We conclude that nonvolatile salts of benzenecarboxylic acids, and perhaps oxalic and acetic acid, should be metastable intermediates of meteoritic organics under oxidizing conditions. Salts of these organic acids would have been largely invisible to GC-MS. Experiments show that one of these, benzenehexacarboxylic acid (mellitic acid), is generated by oxidation of organic matter known to come to Mars, is rather stable to further oxidation, and would not have been easily detected by the Viking experiments. Approximately 2 kg of meteorite-derived mellitic acid may have been generated per m(2) of Martian surface over 3 billion years. How much remains depends on decomposition rates under Martian conditions. As available data do not require that the surface of Mars be very strongly oxidizing, some organic molecules might be found near the surface of Mars, perhaps in amounts sufficient to be a resource. Missions should seek these and recognize that these complicate the search for organics from entirely hypothetical Martian life.  (+info)

DNA HOMO as a new landmark for nucleic acid properties. ab initio calculations and experimental mapping. (3/290)

Of the non-covalent binding forces in DNA-drug or DNA-protein interaction, electrostatic interaction, stacking interaction, hydrogen bonds and hydrophobic effect have been well established. However, only a few HOMO-LUMO interaction in DNA have been reported. We examined the ab initio calculations of B-DNA duplex 5-mers. Based on the calculated results, we investigated the mapping of HOMO experimentally and found that DNA cleavage patterns with Co(II) and BPO (Benzoyl peroxide) were in good agreement with the ab initio calculation results.  (+info)

A novel histone deacetylase inhibitor identified by high-throughput transcriptional screening of a compound library. (4/290)

Libraries of compounds are increasingly becoming commercially available for the use of individual academic laboratories. A high-throughput system based on a stably integrated transcriptional reporter was used to screen a library of random compounds to identify agents that conferred robust augmentation of a signal transduction pathway. A novel histone deacetylase (HDAC) inhibitor, termed scriptaid, conferred the greatest effect, a 12- to 18-fold augmentation. This facilitation of transcriptional events was generally applicable to exogenous gene constructs, including viral and cellular promoters, different cell lines and reporter genes, and stably integrated and transiently introduced sequences. Scriptaid did not interfere with a further induction provided by stimulation of the cognate signal transduction pathway (transforming growth factor beta/Smad4), which implied the functional independence of ligand-stimulated transcriptional activation and histone acetylation states in this system. Additional insights into this and other signal transduction systems are likely to be afforded through the application of compound screening technologies.  (+info)

Automated solid-phase synthesis of oligosaccharides. (5/290)

Traditionally, access to structurally defined complex carbohydrates has been very laborious. Although recent advancements in solid-phase synthesis have made the construction of complex oligosaccharides less tedious, a high level of technical expertise is still necessary to obtain the desired structures. We describe the automated chemical synthesis of several oligosaccharides on a solid-phase synthesizer. A branched dodecasaccharide was synthesized through the use of glycosyl phosphate building blocks and an octenediol functionalized resin. The target oligosaccharide was readily obtained after cleavage from the solid support. Access to certain complex oligosaccharides now has become feasible in a fashion much like the construction of oligopeptides and oligonucleotides.  (+info)

Selective permeation and organic extraction of recombinant green fluorescent protein (gfpuv) from Escherichia coli. (6/290)

BACKGROUND: Transformed cells of Escherichia coli DH5-alpha with pGFPuv, induced by IPTG (isopropyl-beta-d-thiogalactopyranoside), express the green fluorescent protein (gfpuv) during growth phases. E. coli subjected to the combination of selective permeation by freezing/thawing/sonication cycles followed by the three-phase partitioning extraction (TPP) method were compared to the direct application of TPP to the same culture of E. coli on releasing gfpuv from the over-expressing cells. MATERIAL AND METHODS: Cultures (37 degrees C/100 rpm/ 24 h; mu = 0.99 h(-1)-1.10 h(-1)) of transformed (pGFP) Escherichia coli DH5-alpha, expressing the green fluorescent protein (gfpuv, absorbance at 394 nm and emission at 509 nm) were sonicated in successive intervals of sonication (25 vibrations/pulse) to determine the maximum amount of gfpuv released from the cells. For selective permeation, the transformed previously frozen (-75 degrees C) cells were subjected to three freeze/thaw (-20 degrees C/ 0.83 degrees C/min) cycles interlaid by sonication (3 pulses/6 seconds/25 vibrations). The intracellular permeate with gfpuv in extraction buffer (TE) solution (25 mM Tris-HCl, pH 8.0, 1 mM beta-mercaptoethanol beta-ME, 0.1 mM PMSF) was subjected to the three-phase partitioning (TPP) method with t-butanol and 1.6 M ammonium sulfate. Sonication efficiency was verified on the application to the cells previously treated by the TPP method. The intra-cell releases were mixed and eluted through methyl HIC column with a buffer solution (10 mM Tris-HCl, 10 mM EDTA, pH 8.0). RESULTS: The sonication maximum released amount obtained from the cells was 327.67 microg gfpuv/mL (20.73 microg gfpuv/mg total proteins-BSA), after 9 min of treatment. Through the selective permeation by three repeated freezing/thawing/sonication cycles applied to the cells, a close content of 241.19 microg gfpuv/mL (29.74 microg gfpuv/mg BSA) was obtained. The specific mass range of gfpuv released from the same cultures, by the three-phase partitioning (TPP) method, in relation to total proteins, was higher, between 107.28 microg/mg and 135.10 microg/mg. CONCLUSIONS: The selective permeation of gfpuv by freezing/thawing/sonication followed by TPP separation method was equivalent to the amount of gfpuv extracted from the cells directly by TPP; although selective permeation extracts showed better elution through the HIC column.  (+info)

Teaching target-oriented and diversity-oriented organic synthesis at Harvard University. (7/290)

Natural supramolecular building blocks. Wild-type cowpea mosaic virus. (8/290)

Cowpea mosaic virus (CPMV) can be isolated in gram quantities, possesses a structure that is known to atomic resolution, and is quite stable. It is therefore of potential use as a molecular entity in synthesis, particularly as a building block on the nanochemical scale. CPMV was found to possess a lysine residue with enhanced reactivity in each asymmetric unit, and thus 60 such lysines per virus particle. The identity of this residue was established by a combination of acylation, protein digestion, and mass spectrometry. Under forcing conditions, up to four lysine residues per asymmetric unit can be addressed. In combination with engineered cysteine reactivity described in the accompanying paper, this provides a powerful platform for the alteration of the chemical and physical properties of CPMV particles.  (+info)

Hello students! So many of you are likely in the home stretch of Organic Chemistry class and the final exam is rapidly approaching.. Here are three importnat items to consider when studying for the final exam:. 1) Find out exactly what is on the exam. This sounds simple, but we cannot stress enough the importance of finding out exactly what you are expcted to know on your final. Most of the time the final exam is cumulative, however sometimes it is not. In addition, sometimes the exam focuses on the later part of the semseter- possibly on information that was not tested on prior exams for the course.. 2) Know every reaction backwards and forwards. Final exams love to ask you questions that require you to draw upon a vast background of knowledge. Therefore, you must know each organic chemistry reaction backwards and forwards. Consider this:. Organic chemistry reactions are presented in the following basic framework:. A+B→C. Or. Reactant A + Reactant B → Product. In order to truly learn ...

Electrophilic addition-Just like in football, it is easy to say that one of the players is the most important one in the game. While many (nerdy) organic chemists could have a robust debate over a pint as to which of the compound class is most valuable in the reaction, we are going to treat them all as important. In its most basic form, they are all essential in some way or another to the reactions success. Hence, we are going to start with acids and discuss all of the compound classes one by one.. Electrophiles are one of the two most important reactants in organic chemistry. As we have discussed previously on this blog, organic chemistry reactions are all about the flow of electrons, and electrophiles are the ones who want those electrons. When you think of the word electrophile you should think of the Greek word Philos which means to love. Therefore, an electrophilic species is one that loves electrons. Easy enough, right?

The A.E. Favorsky Irkutsk Institute of Chemistry, Siberian Branch of the Russian Academy of Sciences (IrICh) called the Irkutsk Institute of Organic Chemistry until recently, is one of the first academic institutes in the Eastern Siberia. It was founded in 1957. Professor M. F. Shostakovsky of the Moscow Institute of Organic Chemistry, Ac. Sci. USSR, Corresponding Member, Ac. Sci. USSR, was appointed first director-organizer. A close associate of Academician A. E. Favorsky (St. Petersburg, Moscow), a classic of organic chemistry, Shostakovsky laid the basis for dynamic development of the largest Russian classic chemical school - the school of Favorsky on the Siberian ground. Soon the Institute held a world lead in the chemistry of acetylene and silicon (especially, of silico-acetylenic compounds). In 2000 the Institute was given name after A.E. Favorsky.

Gas chromatography-mass spectrometry (GC-MS) is a powerful analytical tool for detection, identification, and quantification of many volatile organic compounds. However, many colleges and universities have not fully incorporated this technique into undergraduate teaching laboratories despite its wide application and ease of use in organic chemistry. In this article, a set of experiments are provided to educators for the purposeful integration of the GC-MS technique into undergraduate organic chemistry laboratories. The laboratories provide students experimental opportunities to use GC-MS as the main analytical tool for (a) identification and quantification of major and minor product(s) formed in three common organic synthesis reactions and (b) extraction, separation, and identification of multiple natural products found in fruits and vegetables.

Bioorganic chemistry is a rapidly growing scientific discipline that combines organic chemistry and biochemistry. While biochemistry aims at understanding biological processes using chemistry, bioorganic chemistry attempts to expand organic-chemical researches (that is, structures, synthesis, and kinetics) toward biology. When investigating metalloenzymes and cofactors, bioorganic chemistry overlaps bioinorganic chemistry. Biophysical organic chemistry is a term used when attempting to describe intimate details of molecular recognition by bioorganic chemistry. Bioorganic chemistry is that branch of life science that deals with the study of biological processes using chemical methods. Nelson J. Leonard, Bioorganic chemistry-a scientific endeavour in continuous transition Pure Appl. Chem., Vol. 66, No. 4, pp. 659-662 ...
Whilst Chemistry is a universal science, studying it at IB is quite different from other courses. The most distinctive difference is that it has considerably more breadth in the coverage of topics. The 11 topic core include: Quantitative Chemistry, Atomic Structure, Periodicity, Bonding, Energetics, Kinetics and Organic Chemistry.. The seven optional topics include modern analytical chemistry, human biochemistry, medicines and drugs, food chemistry, chemistry in industry and society, further organic chemistry and environmental chemistry. Youll be expected to become adept at practical laboratory work, data collection and manipulation, and build a strong scientific awareness. External assessment consists of three written papers, which you may find easier to face having accessed the Marked by Teachers collection of IB Chemistry essays. Internal assessment, which makes up 24% of the marks, consists of an interdisciplinary project, a variety of short and long-term practical investigations and some ...

This module develops and enhances the knowledge of organic chemistry gained in the Level 4 module Organic Chemistry, which underpins both the industrial chemistry and the biological applications of organic molecules. It underpins an in-depth study of the chemistry of carbon compounds from the viewpoint of their synthesis, reactions and mechanisms. The relevance of atomic structure, stereochemistry and functional group chemistry is also developed further to unify the underlying chemistry.. ...
Youre right; the definition in your book is simplistic. A terminal alkyne would be better defined as an alkyne with the formula $\ce{RC_2H}$, differentiating from an internal alkyne, which would have the formula $\ce{RC_2R}$ and the added stipulation that neither R nor R can be a hydrogen. Equivalently stated as in Wikipedia, an internal alkyne has carbon substitutents on all acetylenic carbons, and a terminal alkyne is therefore not an internal alkyne because at least one acetylenic carbon has a hydrogen bonded to it.. The example formula you cite is vinylacetylene, systematic name butenyne or 1-buten-3-yne (heres your IUPAC nomenclature rules favoring double bonds at work; otherwise itd be ethynylbutene or similar). It is indeed an example of a terminal alkyne, having the exploded formula (C2H3)C2H.. ...

A CO-free palladium-catalyzed cyclizative carbonylation of 2-benzylpyridines was developed, leading to pyridoisoquinolinones. This procedure proceeded with the sequential carbonylation of the ortho-C-H bond and the dearomative C-N bond formation. The combination of acetic anhydride and formic acid rather than toxic
As you should know already, carbon is generally found in a tetravalent state - it forms four covalent bonds with other atoms. As you know from the section on alkenes, all four bonds are not necessarily to different atoms, because carbon atoms can double-bond to one another. What this does is create the appearance of only being bound to three other atoms, but in actuality four bonds exist. Alkenes are molecules that consist of carbon and hydrogen atoms where one or more pairs of carbon atoms participate in a double bond, which consists of one sigma (σ) and one pi (π) bond. Alkynes are also molecules consisting of carbon and hydrogen atoms, but instead of forming a double bond with only one sigma (σ) and one pi (π) bond, the alkyne has at least one pair of carbon atoms who have a σ and two π bonds -- a triple bond. The carbon-carbon triple bond, then, is a bond in which the carbon atoms share an s and two p orbitals to form just one σ and two π bonds between them. This results in a linear ...
Alkenes, like Alkanes, have carbon backbones but contain at least one carbon-carbon double bond. Double bonds are reactive and can be reduced to single bonds using hydrogen gas, pressure, and a catalyst, such as Pd or Pt. Alternatively, Alkenes can be reduced to Alkanes by reacting with Hydrogen gas over a Nickel catalyst. Nickel acts as a heterogeneous surface catalyst, weakening the H-H bonds in hydrogen, thus speeding up the reaction. This also leads to syn addition, where both of the hydrogens are added to the same side of the double bond. General Alkene Formula: CnH2n. Suffix: ene Example: CH2CH2 - Ethene See the alkane naming scheme for branched molecules, as the same principal applies to alkenes we simply retain the ene rather than the ane ending. However, the placement of the double bond matters when naming. Example: CH3(CH)2CH3 - 2-butene Example: CH2CHCH2CH3 - 1-butene IUPAC rules actually specify that alkenes should be named as but-1-ene, but-2-ene, and so on; but the practice ...
Alkenes and alkynes can be transformed into almost any other functional group you can name! We will review their nomenclature, and also learn about the vast possibility of reactions using alkenes and alkynes as starting materials.
Presentation Speech by Professor Hj. Théel, President of the Swedish Royal Academy of Sciences on December 10, 1902. Your Majesty, Your Royal Highnesses, Ladies and Gentlemen.. The Royal Academy of Sciences has resolved to award the 1902 Nobel Prize for Chemistry to Dr. Emil Fischer, Professor at Berlin University and Geheimrat, for the extraordinary services he has rendered by his work on sugar and purine syntheses.. One of the main tasks of organic chemistry is to investigate and reproduce artificially those processes occurring in living matter, both animal and vegetable, in order thereby to provide a firm basis for the concepts regarding biological phenomena. Apart from the protein substances there is no group of carbon compounds more important for organic life than the carbohydrates. For that reason the carbohydrates, and in particular the sugars, have been the object of countless studies since the beginning of organic chemistry. Owing to the nature of these substances their study was ...

So isobutyraldehyde cannot escape its ultimate fate --- the irreversible Cannizzaro reaction. While hydroxide adds reversibly to the carbonyl group of isobutyraldehyde to provide alkoxide 5, transfer of hydride to isobutyraldehyde is irreversible (red arrows; its all downhill from here!). The bis-alkoxide 5 has been suggested as the active hydride transfer species. The immediate products are isobutyric acid (6) and the alkoxide 7. Proton exchange as shown for economy of space but more like via the agency of aqueous NaOH, gives the respective carboxylate 8 and isobutyl alcohol 9. If these two species are independently subjected to the reaction conditions, isobutyraldehyde will not be formed. Moreover, treatment of aldol 4 under the reaction conditions will also channel itself into the anion of isobutyric acid (8) and isobutyl alcohol (9 ...

Peptoid-type oligoamides is a particular class of foldamers that, due to their intrinsic properties, do not adopt secondary structure induced by a network of intramolecular hydrogen bonds.[1] The chemists, notably the PEPTOID group from ICCF, have made the conformational flexibility of the peptoid backbone an asset by developing conformational control tools that allow the personalized design of various secondary structures.[2] The doctoral work will focus on the design, synthesis and study of new peptoid-type amphiphilic architectures with varied secondary structures (helix, ribbon …etc). For the design of these architectures, the project is based on i) the intrinsic properties of different peptoid-type skeletons, ii) new structuring tools and iii) promising results concerning the antibacterial activities of short peptoid oligomers based on triazolium.[3] For the preparation of the various edifices, synthesis methods in solution or on support will be used to access linear or cyclic oligomers. ...

Alistair Stephen was educated at South African College School (SACS) and at UCT, where he obtained the BSc (with distinctions in Chemistry and Physics), MSc and PhD. He then proceeded to Oxford University on a Rhodes Scholarship, duly completing the DPhil under supervision of the legendary Sir Robert Robinson, who during that period was awarded the 1947 Nobel Prize for Chemistry. On his return to South African in 1949 he worked first at the CSIR in Pretoria, before his appointment as a lecturer in Chemistry at UCT in 1951, and in 1962 as Mally Chair of Organic Chemistry, a position he occupied until his retirement in 1987. During this period he headed the Department of Organic Chemistry, which was part of the School of Chemistry at that time, and also established and directed the CSIR Carbohydrate Research Unit. The latter represented a consolidation of his seminal scientific contributions in the area of structural studies on polysaccharides and glycoconjugates of bacterial and plant origin. He ...
You note that the surprising result from Bordens work is the inverse H/D isotope effect, but I find more surprising the quoted reported magnitude of the 12C/14C effect (k(14C/12C)=5.46 in the blog). I have checked Bordens article, and the magnitude is indeed what is quoted (although its not discussed in the text unless I missed it). In my experience, carbon isotope effects are normally measured as small percentages, and I think it far more likely that what was meant was a 5.46% effect, ie 1.055. A 546% effect, which is how Bordens paper reads, would be way by far the largest carbon isotope effect ever recorded (and since carbon does not really tunnel, it cannot be due to that effect), and indeed is up there with hydrogen isotope effects! There is a minor error in the blog, it should be k(12C/14C) rather than the way you have it (heavier isotopes do normally react more slowly). Have I missed something in Bordens article, or should we invite the man himself to comment on this blog?. ...
